Home / VBA / VBA IF OR (Test Multiple Conditions)
You can use the OR operator with the VBA IF statement to test multiple conditions. When you use it, it allows you to test two or more conditions simultaneously and returns true if any of those conditions are true. But if all the conditions are false only then it returns false in the result.
Use OR with IF
- First, start the IF statement with the “IF” keyword.
- After that, specify the first condition that you want to test.
- Next, use the OR keyword to specify the second condition.
- In the end, specify the second condition that you want to test.
To have a better understanding let’s see an example.
Sub myMacro()
'two conditions to test using OR
If 1 = 1 Or 2 < 1 Then
MsgBox "One of the conditions is true."
Else
MsgBox "None of the conditions are true."
End If
End Sub
If you look at the above example, we have specified two conditions one if (1 = 1) and the second is (2 < 1), and here only the first condition is true, and even though it has executed the line of code that we have specified if the result is true.
Now let’s see if both conditions are false, let me use a different code here.
Sub myMacro()
'two conditions to test using OR
If 1 = 2 Or 2 < 1 Then
MsgBox "One of the conditions is true."
Else
MsgBox "None of the conditions are true."
End If
End Sub
In the above code, both conditions are false, and when you run this code, it executes the line of code that we have specified if the result is false.
In the same way, you can also test more than two conditions at the same time. Let’s continue the above example and add the third condition to it.
Sub myMacro()
'three conditions to test using OR
If 1 = 1 And 2 > 1 And 1 - 1 = 0 Then
MsgBox "one of the conditions is true."
Else
MsgBox "none of the conditions are true."
End If
End Sub
Now we have three conditions to test, and we have used the OR after the second condition to specify the third condition. As you learned above that when you use OR, any of the conditions need to be true to get true in the result. When you run this code, it executes the line of code that we have specified for the true.
And if all the conditions are false, just like you have in the following code, it returns false.
Sub myMacro()
'three conditions to test using OR
If 1 < 1 And 2 < 1 And 1 + 1 = 0 Then
MsgBox "one of the conditions is true."
Else
MsgBox "none of the conditions are true."
End If
End Sub

VBA If Statement
If Then
VBA If Statements allow you to test if expressions are TRUE or FALSE, running different code based on the results.
Let’s look at a simple example:
If Range("a2").Value > 0 Then Range("b2").Value = "Positive"
This tests if the value in Range A2 is greater than 0. If so, setting Range B2 equal to “Positive”
Note: When testing conditions we will use the =, >, <, <>, <=, >= comparison operators. We will discuss them in more detail later in the article.
Here is the syntax for a simple one-line If statement:
If [test_expression] then [action]
To make it easier to read, you can use a Line Continuation character (underscore) to expand the If Statements to two lines (as we did in the above picture):
If [test_expression] then _
[action]
If Range("a2").Value > 0 Then _
Range("b2").Value = "Positive"
End If
The above “single-line” if statement works well when you are testing one condition. But as your IF Statements become more complicated with multiple conditions, you will need to add an “End If” to the end of the if statement:
If Range("a2").Value > 0 Then
Range("b2").Value = "Positive"
End If
Here the syntax is:
If [test_expression] then
[action]
End If
The End If signifies the end of the if statement.
Now let’s add in an ElseIF:
ElseIF – Multiple Conditions
The ElseIf is added to an existing If statement. ElseIf tests if a condition is met ONLY if the previous conditions have not been met.
In the previous example we tested if a cell value is positive. Now we will also test if the cell value is negative with an ElseIf:
If Range("a2").Value > 0 Then
Range("b2").Value = "Positive"
ElseIf Range("a2").Value < 0 Then
Range("b2").Value = "Negative"
End If
You can use multiple ElseIfs to test for multiple conditions:
Sub If_Multiple_Conditions()
If Range("a2").Value = "Cat" Then
Range("b2").Value = "Meow"
ElseIf Range("a2").Value = "Dog" Then
Range("b2").Value = "Woof"
ElseIf Range("a2").Value = "Duck" Then
Range("b2").Value = "Quack"
End If
End Sub
Now we will add an Else:
Else
The Else will run if no other previous conditions have been met.
We will finish our example by using an Else to indicate that if the cell value is not positive or negative, then it must be zero:
If Range("a2").Value > 0 Then
Range("b2").Value = "Positive"
ElseIf Range("a2").Value < 0 Then
Range("b2").Value = "Negative"
Else
Range("b2").Value = "Zero"
End If
If-Else
The most common type of If statement is a simple If-Else:
Sub If_Else()
If Range("a2").Value > 0 Then
Range("b2").Value = "Positive"
Else
Range("b2").Value = "Not Positive"
End If
End Sub
Nested IFs
You can also “nest” if statements inside of each other.
Sub Nested_Ifs()
If Range("a2").Value > 0 Then
Range("b2").Value = "Positive"
Else
If Range("a2").Value < 0 Then
Range("b2").Value = "Negative"
Else
Range("b2").Value = "Zero"
End If
End If
End Sub

IF – Or, And, Xor, Not
Next we will discuss the logical operators: Or, And, Xor, Not.
If Or
The Or operator tests if at least one condition is met.
The following code will test if the value in Range A2 is less than 5,000 or greater than 10,000:
If Range("a2").Value < 5000 Or Range("a2").Value > 10000 Then
Range("b2").Value = "Out of Range"
End If
You can include multiple Ors in one line:
If Range("a2").Value < 5000 Or Range("a2").Value > 10000 Or Range("a2").Value = 9999 Then
Range("b2").Value = "Out of Range"
End If
If you are going to use multiple Ors, it’s recommended to use a line continuation character to make your code easier to read:
If Range("a2").Value < 5000 Or _
Range("a2").Value > 10000 Or _
Range("a2").Value = 9999 Then
Range("b2").Value = "Out of Range"
End If
If And
The And operator allows you to test if ALL conditions are met.
If Range("a2").Value >= 5000 And Range("a2").Value <= 10000 Then
Range("b2").Value = "In Range"
End If

If Xor
The Xor operator allows you to test if exactly one condition is met. If zero conditions are met Xor will return FALSE, If two or more conditions are met, Xor will also return false.
I’ve rarely seen Xor used in VBA programming.
If Not
The Not operator is used to convert FALSE to TRUE or TRUE To FALSE:
Sub IF_Not()
MsgBox Not (True)
End Sub
Notice that the Not operator requires parenthesis surrounding the expression to switch.
The Not operator can also be applied to If statements:
If Not (Range("a2").Value >= 5000 And Range("a2").Value <= 10000) Then
Range("b2").Value = "Out of Range"
End If
If Comparisons
When making comparisons, you will usually use one of the comparison operators:
Comparison Operator | Explanation |
---|---|
= | Equal to |
<> | Not Equal to |
> | Greater than |
>= | Greater than or Equal to |
< | Less than |
<= | Less than or Equal to |
However, you can also use any expression or function that results in TRUE or FALSE
If – Boolean Function
When build expressions for If Statements, you can also use any function that generates TRUE or False. VBA has a few of these functions:
Function | Description |
---|---|
IsDate | Returns TRUE if expression is a valid date |
IsEmpty | Check for blank cells or undefined variables |
IsError | Check for error values |
IsNull | Check for NULL Value |
IsNumeric | Check for numeric value |
They can be called like this:
If IsEmpty(Range("A1").Value) Then MsgBox "Cell Empty"
Excel also has many additional functions that can be called using WorksheetFunction. Here’s an example of the Excel IsText Function:
If Application.WorksheetFunction.IsText(Range("a2").Value) Then _
MsgBox "Cell is Text"
You can also create your own User Defined Functions (UDFs). Below we will create a simple Boolean function that returns TRUE. Then we will call that function in our If statement:
Sub If_Function()
If TrueFunction Then
MsgBox "True"
End If
End Sub
Function TrueFunction() As Boolean
TrueFunction = True
End Function
Comparing Text
You can also compare text similar to comparing numbers:
Msgbox "a" = "b"
Msgbox "a" = "a"
When comparing text, you must be mindful of the “Case” (upper or lower). By default, VBA considers letters with different cases as non-matching. In other words, “A” <> “a”.
If you’d like VBA to ignore case, you must add the Option Compare Text declaration to the top of your module:
Option Compare Text
After making that declaration “A” = “a”:
Option Compare Text
Sub If_Text()
MsgBox "a" = "A"
End Sub

VBA If Like
The VBA Like Operator allows you to make inexact comparisons of text. Click the “Like Operator” link to learn more, but we will show a basic example below:
Dim strName as String
strName = "Mr. Charles"
If strName Like "Mr*" Then
MsgBox "True"
Else
MsgBox "False"
End If
Here we’re using an asterisk “*” wildcard. The * stands for any number of any characters. So the above If statement will return TRUE. The Like operator is an extremely powerful, but often under-used tool for dealing with text.
If Loops
VBA Loops allow you to repeat actions. Combining IF-ELSEs with Loops is a great way to quickly process many calculations.
Continuing with our Positive / Negative example, we will add a For Each Loop to loop through a range of cells:
Sub If_Loop()
Dim Cell as Range
For Each Cell In Range("A2:A6")
If Cell.Value > 0 Then
Cell.Offset(0, 1).Value = "Positive"
ElseIf Cell.Value < 0 Then
Cell.Offset(0, 1).Value = "Negative"
Else
Cell.Offset(0, 1).Value = "Zero"
End If
Next Cell
End Sub
If Else Examples
Now we will go over some more specific examples.
Check if Cell is Empty
This code will check if a cell is empty. If it’s empty it will ignore the cell. If it’s not empty it will output the cell value to the cell to the right:
Sub If_Cell_Empty()
If Range("a2").Value <> "" Then
Range("b2").Value = Range("a2").Value
End If
End Sub
AutoMacro | Ultimate VBA Add-in | Click for Free Trial!
Check if Cell Contains Specific Text
The Instr Function tests if a string of text is found in another string. Use it with an If statement to check if a cell contains specific text:
If Instr(Range("A2").value,"text") > 0 Then
Msgbox "Text Found"
End If
Check if cell contains text
This code will test if a cell is text:
Sub If_Cell_Is_Text()
If Application.WorksheetFunction.IsText(Range("a2").Value) Then
MsgBox "Cell is Text"
End If
End Sub
If Goto
You can use the result of an If statement to “Go to” another section of code.
Sub IfGoTo ()
If IsError(Cell.value) Then
Goto Skip
End If
'Some Code
Skip:
End Sub
Delete Row if Cell is Blank
Using Ifs and loops you can test if a cell is blank and if so delete the entire row.
Sub DeleteRowIfCellBlank()
Dim Cell As Range
For Each Cell In Range("A2:A10")
If Cell.Value = "" Then Cell.EntireRow.Delete
Next Cell
End Sub

If MessageBox Yes / No
With VBA Message Boxes you’re able to ask the user to select from several options. The Yes/No Message Box asks the user to select Yes or No. You can add a Yes / No Message Box to a procedure to ask the user if they would like to continue running the procedure or not. You handle the user’s input using an If statement.
Here is the Yes/No Message Box in practice:
Sub MsgBoxVariable()
Dim answer As Integer
answer = MsgBox("Do you want to Continue?", vbQuestion + vbYesNo)
If answer = vbYes Then
MsgBox "Yes"
Else
MsgBox "No"
End If
End Sub
VBA If, ElseIf, Else in Access VBA
The If, ElseIf and Else functions work exactly the same in Access VBA as in Excel VBA.
You can use an If statement to check if there are records in a Recordset.
IF OR is not a single statement. Rather, these are two logical functions used together in VBA when we have more than one criteria to check. When we use the IF statement, if any criteria meet, we get the TRUE result. OR statement is used between the two criteria of the IF statement.
IF OR Function in VBA
Logical functions are the heart of any criteria-based calculations. The IF function is the most popular logical function, be it a worksheet function or a VBA function because it serves excellently for our needs. But one more logical function, OR in excel, is the most underrated. It is also important to master when it comes to solving complex calculations. This article will take you through the VBA IF OR function in detail. Read the full article to get the function in detail.

How to Use IF with OR Function in VBA?
We will show you a simple example of using the IF OR function in VBA.
You can download this VBA IF OR Excel Template here – VBA IF OR Excel Template
A combination of logical functions is the best pair in Excel. However, combining many logical formulas inside the other logical formula suggests that calculation requires many conditions to test.
Now, look at the syntax of the IF OR function in VBA.
[Test] OR [Test] OR [Test]
It is the same as we saw in the worksheet example. For a better understanding, look at the below example.
We have the previous month’s price, the last 6-month average price, and the current monthly price here.
To decide whether to buy the product, we need to do some tests here, and those tests are.
If the Current Price is less than or equal to any of the other two prices, we should get the result as “Buy” or else should get the result as “Do Not Buy.”
Step 1: Open the IF condition inside the Sub procedure.
Code:
Sub IF_OR_Example1() If End Sub
Step 2: Inside the IF condition, apply the first logical test as Range(“D2”).Value <= Range(“B2”).Value
Code:
Sub IF_OR_Example1() If Range(“D2”).Value <= Range(“B2”).Value End Sub
Step 3: The first logical condition completes. Now, open OR statement.
Code:
Sub IF_OR_Example1() If Range("D2").Value <= Range("B2").Value OR End Sub
Step 4: Now, apply the second logical condition as Range(“D2”).Value <= Range(“C2”).Value
Code:
Sub IF_OR_Example1() If Range("D2").Value <= Range("B2").Value OR Range("D2").Value <= Range("C2").Value End Sub
Step 5: We are done with the logical tests here. After the logical tests, put the word “Then.”
Code:
Sub IF_OR_Example1() If Range("D2").Value <= Range("B2").Value Or Range("D2").Value <= Range("C2").Value Then End Sub
Step 6: In the next line, write what the result should be if the logical testA logical test in Excel results in an analytical output, either true or false. The equals to operator, “=,” is the most commonly used logical test.read more is TRUE. If the condition is TRUE, we need the result as “Buy” in cell E2.
Code:
Sub IF_OR_Example1() If Range("D2").Value <= Range("B2").Value Or Range("D2").Value <= Range("C2").Value Then Range("E2").Value = "Buy" End Sub
Step 7: If the result is FALSE, we should get the result as “Do Not Buy.” So in the next line, put “Else” and write the code in the next line.
Code:
Sub IF_OR_Example1() If Range("D2").Value <= Range("B2").Value Or Range("D2").Value <= Range("C2").Value Then Range("E2").Value = "Buy" Else Range("E2").Value = "Do Not Buy" End Sub
Step 8: Close the IF statement with “End If.”
Code:
Sub IF_OR_Example1() If Range("D2").Value <= Range("B2").Value Or Range("D2").Value <= Range("C2").Value Then Range("E2").Value = "Buy" Else Range("E2").Value = "Do Not Buy" End If End Sub
We complete the coding part.
Let us run this code using F5 or manually through the run option and see the result in cell E2.
We got the result as “Buy” because the current monthly price of Apple is less than the price of both “Previous Month” as well as “6 Month Average Price”.
IF OR VBA Function with Loops (Advanced)
Once you understand the formula, try to use it with a larger number of cells. In the case of a larger number of cells, we cannot write any line of code, so we need to use VBA loopsA VBA loop in excel is an instruction to run a code or repeat an action multiple times.read more.
We have added a few more lines for the above data set.
We need to use the For Next Loop here.
Just keep the current code as it is.
Declare the variable as an Integer.
Now, open For Next Loop from 2 to 9.
Now, wherever we have cell referenceCell reference in excel is referring the other cells to a cell to use its values or properties. For instance, if we have data in cell A2 and want to use that in cell A1, use =A2 in cell A1, and this will copy the A2 value in A1.read more, change the current number, and concatenate the variable “k” with them.
For example, Range (“D2”).Value should be Range (“D” & k).Value
Now, run the code. First, we should get the status in all the cells.
You can copy the code below.
Code:
Sub IF_OR_Example1() Dim k As Integer For k = 2 To 9 If Range("D" & k).Value <= Range("B" & k).Value Or Range("D" & k).Value <= Range("C" & k).Value Then Range("E" & k).Value = "Buy" Else Range("E" & k).Value = "Do Not Buy" End If Next k End Sub

Introduction
One of the most common things to do in coding is to build logic that checks for the occurrence of multiple conditions. As a coder, whether novice or experienced, hopefully you agree that this is one of the most common coding tasks.
In VBA, If statements are commonly used to build such logic. For example, you could build logic that checks if the weather is good today.
If it is, then you can leave home. If it is not, then check if it’s slightly raining or if it’s a blizzard. If it is slightly raining and you have your rain coat ready, then you can leave. This is a simple scenario, but it resembles a lot of common coding problems.
We mostly can handle such logic by using the IF statement with multiple conditions. An alternative that makes sense under certain conditions is to use the Select Case statement. In this guide, we will focus on the If Statement with multiple conditions, but we will also briefly mention the basics of Select Case statement as well as when to use it.
IF Statement Syntax Table
Description | Format | Example |
If Then | If [condition is true] Then [do something] End If | If Good_Weather = True Then MsgBox “Go Out” End If |
If without End If (only one line) | If [condition is true] Then [do something] | If Good_Weather then MsgBox “Go Out” |
If Else | If [condition is true] Then [do something] Else [do something] End If | If Rain_Coat_Ready = True Then MsgBox “Go Out” Else MsgBox “Stay Home” End If |
If ElseIf | If [condition 1 is true] Then [do something] ElseIf [condition2 is true] Then [do something] End If | If Good_Weather = True Then Msgbox “Go Out” ElseIf Good_Weather = False AND Rain_Coat_Ready = True Then Msgbox “Go Out” End if |
ElseIf and Else (must be in this order) | If [condition1 is true] Then [do something] ElseIf [condition 2 is true] Then [do something] End If | If Good_Weather = True Then Msgbox “Go Out” ElseIf Good_Weather = False AND Rain_Coat_Ready = True Then Msgbox “Go Out” Else Msgbox “Stay Home” End if |
Logic Gates
X | Y | AND RESULT | OR RESULT |
TRUE | TRUE | AND | TRUE |
TRUE | FALSE | FALSE | TRUE |
FALSE | TRUE | FALSE | TRUE |
FALSE | FALSE | FALSE | FALSE |
Example 1: Should I go out today?
We will develop the logic for the above diagram step-by-step.
Sub ShouldIGoOutToday() 'Set the weather to good or bad Good_Weather = False 'Set the Rain coat to ready or not Rain_Coat_Ready = True 'Set the type of bad weather Bad_Weather = "Some Rain" If Good_Weather = True Then 'if weather is good then go out MsgBox "Go Out" Else 'if weather is not good If Bad_Weather = "Some Rain" Then 'If the bad weather is some rain If Rain_Coat_Ready = True Then 'If the bad weather is some rain and the rain coat is ready MsgBox "Go Out" Else 'if the bad weather is some reain and the rain coat is not ready MsgBox "Stay Home" End If ElseIf Bad_Weather = "Blizzard" Then 'if the bad weather is blizzard MsgBox " Stay Home" End If End If End Sub
Example 2: Using AND / OR
You could specify multiple conditions within the same condition by using AND and OR. Instead of checking that condition = True
, we could check that condition1 = True AND condition2 = True
. This can be applied to the above example by checking if the bad weather is ‘some rain’ AND the rain coat is ready.
Sub ShouldIGoOutTodayEx2() 'Set the weather to good or bad Good_Weather = False 'Set the Rain coat to ready or not Rain_Coat_Ready = True 'Set the type of bad weather Bad_Weather = "Some Rain" If Good_Weather = True Then 'if weather is good then go out MsgBox "Go Out" Else 'if weather is not good If Bad_Weather = "Some Rain" And Rain_Coat_Ready = True Then 'If the bad weather is some rain AND the rain coat is ready then Go Out MsgBox "Go Out" ElseIf Bad_Weather = "Blizzard" Or Rain_Coat_Ready = False Then 'if the bad weather is blizzard or the rain coat is not ready then Stay Home MsgBox " Stay Home" End If End If End Sub
For more on using AND and OR with If statements, see this article:
Alternative to If Statement: Select Case
The most obvious way to select case is to do something when we are only interested in the value of a particular variable and the things we do will depend on the value of that variable.
In our above example, there is no single variable that we depend on to decide the outcome. We will attempt to implement the above logic using Select Case.
The main difference between the Select Case and If statements is that Select Case allows you to only ‘do something’ based on the value of the Select Case variable. In order to overcome this hurdle, you can set the Select Case variable to True. You would then specify the full condition after the keyword Case and the thing we want to do when it is met on the next line.
Hence, instead of this syntax:
If X = 2 and Y = 3 then
[do something]
End if
With Select Case, it is this syntax:
Select Case True
Case X = 2 and Y = 3
[do something]
End Select
The full implementation of the above examples using Select Case is shown below:
Sub ShouldIGoOutTodayEx3() 'Set the weather to good or bad Good_Weather = False 'Set the Rain coat to ready or not Rain_Coat_Ready = False 'Set the type of bad weather Bad_Weather = "Some Rain" Select Case True Case Good_Weather = True MsgBox "Go Out" Case Good_Weather = False And Bad_Weather = "Some Rain" And Rain_Coat_Ready = True MsgBox "Go Out" Case Good_Weather = False And Bad_Weather = "Some Rain" And Rain_Coat_Ready = False MsgBox "Stay Home" Case Good_Weather = False And Bad_Weather = "Blizzard" MsgBox "Stay Home" End Select End Sub
Summary
If statements are ideal for handling simple and complex logic that involves multiple conditions and things we want to happen accordingly. On the other hand, Select Case could also be used as an alternative, but it’s usually meant for a situation where we want to select a single thing to do out of a number of potential things. When the logic gets more complex and multiple levels get added to the logic, the Select Case becomes less intuitive.

In Excel VBA, IF Then Else statement allows you to check for a condition, and perform an action accordingly.
This is extremely valuable in many situations as we will see in the examples later in this tutorial.
To give you a simple example, suppose you have a list of grades in Excel and you want to highlight all those students who have scored an A. Now, if I ask you to do this manually, you will check each student’s grade and if it’s an A, you’ll highlight it, and if it isn’t, then you’ll leave it as is.
The same logic can be built in VBA using the If Then Else statement as well (and of course do a lot more than just highlighting grades).
In this tutorial, I’ll show you different ways the ‘If Then Else’ construct can be used in Excel VBA, and some practical examples in action.
But before I get into the specifics, let me give you the syntax of the ‘IF Then Else’ statement.
If you’re interested in learning VBA the easy way, check out my Online Excel VBA Training.
Syntax – IF Then Else
Below is the generic syntax of If Then Else construct in VBA
IF condition Then true_code [Else false_code]
Or
IF condition Then true_code Else false_code End IF
Note that the Else part of this statement is optional.
Now if you’re wondering what’s the difference between the two syntaxes, let me clarify.
The first syntax is a simple one-line IF THEN ELSE statement where you don’t need to use the END IF statement.
However, in the second syntax, the true_code part is in the second line. This is helpful when the code that you need to run in case the IF condition is true is long and consists of multiple lines.
When you split the IF statement into multiple lines, you need to tell VBA where the IF Then construct ends.
Hence you need to use the End IF statement.
In case you don’t use End IF when required, VBA will show you an error – “Block IF without END IF”
Examples of Using IF Then Statement in VBA
To give you an idea of how the IF-THEN statement works in VBA, let me start with some basic examples (some practical and more useful examples are covered later in this tutorial).
Suppose you have a student’s score in cell A1 and you want to check whether the student passed the exam or not (passing marks threshold being 35).
Then you can use the following code:
Sub CheckScore() If Range("A1").Value >=35 Then MsgBox "Pass" End Sub
The above code has a single line of IF statement that checks the value in cell A1.
If it’s more than 35, it shows the message – “Pass”.
If it’s less than 35, nothing happens.
But what if you want to show a message in both the cases, whether a student passed or failed the exam.
The below code would do this:
Sub CheckScore() If Range("A1").Value >= 35 Then MsgBox "Pass" Else MsgBox "Fail" End If End Sub
The above code uses the IF as well as the ELSE statement to execute two different conditions. When the score is more than (or equal to) 35, the IF condition is true, and the code right below it gets executed (everything before the Else statement).
But when the IF condition is FALSE, the code jumps to the Else part and executes the code block in it.
Note that when we use a single line of IF Then statement, we don’t need to use End IF. But when we split it into more than one line, we need to use the End If statement.
Nested IF Then (Multiple IF Then statements)
So far we have used a single IF Then statement.
In case you have multiple conditions to check, you can use:
- Multiple IF conditions
- If Then Else statement
- IF Then ElseIf Else construct
Let me show you how these differ and how to use this in Excel VBA.
Multiple IF Then Statements
Let’s take the same example of using a student’s score.
If the student scores less than 35, the message to display is ‘Fail’, if the score is more than or equal to 35, the message to display is ‘Pass’.
We can use the below code to get this done:
Sub CheckScore() If Range("A1").Value < 35 Then MsgBox "Fail" If Range("A1").Value >= 35 Then MsgBox "Pass" End Sub
You can use multiple IF Then statement as shown above. While this works, it’s not an example of good coding (as you will see the alternatives below).
In case you decide to use this, remember that these statements should either be independent or mutually exclusive. The important thing to know here is that in the above construct, all the IF statements are evaluated and the ones where the condition is true, the code is executed.
So even if the first IF statement is correct, the second would still be evaluated.
IF Then Else Statement
Suppose this time, instead of just displaying the message Pass/Fail, we have one more condition.
If the student scores less than 35, the message to display is ‘Fail’, if the score is more than or equal to 35, the message to display is ‘Pass’, and if the score is more than 80, the message to display is ‘Pass, with Distinction’.
We can use the below code to get this done:
Sub CheckScore() If Range("A1").Value < 35 Then MsgBox "Fail" Else If Range("A1").Value < 80 Then MsgBox "Pass" Else MsgBox "Pass, with Distinction" End If End If End Sub
In the above code, we have used multiple IF statements (nested IF Then) with the help of Else.
So there is an ‘IF Then Else’ construct within an ‘IF Then Else’ construct. This type of nesting allows you to check for multiple conditions and run the relevant block of code.
IF Then ElseIf Else Statement
The above code (that we saw in the previous section) can be further optimized by using the ElseIf statement.
Here is what we’re trying to do – If the student scores less than 35, the message to display is ‘Fail’, if the score is more than or equal to 35, the message to display is ‘Pass’, and if the score is more than 80, the message to display is ‘Pass, with Distinction’.
Sub CheckScore() If Range("A1").Value < 35 Then MsgBox "Fail" ElseIf Range("A1").Value < 80 Then MsgBox "Pass" Else MsgBox "Pass, with Distinction" End If End Sub
The above code uses ElseIf, which allows us to keep all the conditions within one single IF Then statement.
Using AND and OR in IF Then Else
So far in this tutorial, we have only checked for a single condition at a time.
However, when you have multiple dependent conditions, you can use the AND or OR statement with the IF conditions.
Below is the syntax of using AND/OR condition with the IF Then statement.
IF Condition1 AND Condition2 Then true_code Else false_code End IF
In the above code, only when both Condition1 and Condition2 are met, the true_code is executed. Even if one of the conditions is false, it will execute the false_code.
With OR, even if one of the conditions are true, it will execute the true_code. Only when all the conditions are false, it executes the false_code.
Now let’s see how AND and OR statement work with the IF Then Else construct.
Suppose you have the scores for two subjects instead of one, and you want to check for the following conditions:
- Fail – When the score is less than 35 in any of the subjects.
- Pass – When the score is more than or equal to 35, but less than 80 in both the subjects.
- Pass, with Distinction – When the score is more than 35 in both the subjects and is more than or equal to 80 in one or both the subjects.
Here is the code that will do this:
Sub CheckScore() If Range("A1").Value < 35 Or Range("B1").Value < 35 Then MsgBox "Fail" ElseIf Range("A1").Value < 80 And Range("B1").Value < 80 Then MsgBox "Pass" Else MsgBox "Pass, with Distinction" End If End Sub
The above code uses both OR and AND statements.
You can also write this same code with a slight change (using OR instead of AND).
Sub CheckScore() If Range("A1").Value < 35 Or Range("B1").Value < 35 Then MsgBox "Fail" ElseIf Range("A1").Value > 80 Or Range("B1").Value > 80 Then MsgBox "Pass, with Distinction" Else MsgBox "Pass" End If End Sub
Both the above VBA codes will give you the same result. Personally, I prefer the first one as it has a logical flow of checking the scores (but that’s just me).
Using Not Equal to in If Then
In all the examples above, we have used the conditions that check whether a value equal to a specified value or not.
You can also use similar codes when checking when the value is not equal to a specified value in the VBA code. Not equal to represented by <> the Excel VBA.
To see a practical example of using <>, have a look at Example 1 below.
Using If Then Else with Loops in VBA
So far, we have been going through some examples that are good to understand how the ‘IF-THEN’ statements work in VBA, however, are not useful in the practical world.
If I need to grade students, I can easily do that using Excel functions.
So let’s have a look at some useful and practical examples that can help you automate some stuff and be more efficient.
Example 1 – Save and Close All Workbooks Except The Active Workbook
If you have a lot of workbooks open and you quickly want to close all, except the active workbook, you can use the below code,
Sub SaveCloseAllWorkbooks() Dim wb As Workbook For Each wb In Workbooks On error resume next If wb.Name <> ActiveWorkbook.Name Then wb.Save wb.Close End If Next wb End Sub
The above code would save and close all the workbooks (except the active one).
It uses the For Next loop to go through the collection of all the open workbooks and checks the name using the IF condition.
If the name is not the same as that of the Active workbook, it saves and closes it.
In case there is a VBA code in any of the workbooks and you haven’t saved it as .xls or .xlsm, you will see a warning (as the vba codes are lost when you save it in .xlsx format).
Example 2 – Highlight Cells with Negative Values
Suppose that you have a column full of numbers and you want to quickly highlight all the cells with negative values in red, you can do that using the below code.
Sub HighlightNegativeCells() Dim Cll As Range For Each Cll In Selection If Cll.Value < 0 Then Cll.Interior.Color = vbRed Cll.Font.Color = vbWhite End If Next Cll End Sub
The above code uses the For Each loop and checks each cell in the selection that you have made. If the cell has a value that is negative, it’s highlighted in red with white font color.
Example 3 – Hide All the Worksheet Except the Current Worksheet
In case you want to quickly hide all the worksheets except the active one, you can use the below code:
Sub HideAllExceptActiveSheet() Dim ws As Worksheet For Each ws In ThisWorkbook.Worksheets If ws.Name <> ActiveSheet.Name Then ws.Visible = xlSheetHidden Next ws End Sub
The above code uses the For Each loop to go through a collection of worksheets. It checks the name of each worksheet and hides it if it’s not the active worksheet.
Example 4 – Extract the Numeric Part from an Alphanumeric String
If you have alphanumeric strings in cells and you want to extract the numeric part from it, you can do that using the below code:
Function GetNumeric(CellRef As String) Dim StringLength As Integer StringLength = Len(CellRef) For i = 1 To StringLength If IsNumeric(Mid(CellRef, i, 1)) Then Result = Result & Mid(CellRef, i, 1) Next i GetNumeric = Result End Function
This code will create a custom function in Excel that can use within the worksheet (just like a regular function).
Where to Put the VBA Code?
Wondering where the VBA code goes in your Excel workbook?
Excel has a VBA backend called the VB editor. You need to copy and paste the code in the VB Editor module code window.
Here are the steps to do this:
- Go to the Developer tab.
- Click on Visual Basic option. This will open the VB editor in the backend.
- In the Project Explorer pane in the VB Editor, right-click on any object for the workbook in which you want to insert the code. If you don’t see the Project Explorer go to the View tab and click on Project Explorer.
- Go to Insert and click on Module. This will insert a module object for your workbook.
- Copy and paste the code in the module window.

Quick Guide to the VBA If Statement
Description | Format | Example |
---|---|---|
If Then | If [condition is true] Then [do something] End If |
If score = 100 Then Debug.Print «Perfect» End If |
If Else | If [condition is true] Then [do something] Else [do something] End If |
If score = 100 Then Debug.Print «Perfect» Else Debug.Print «Try again» End If |
If ElseIf | If [condition 1 is true] Then [do something] ElseIf [condition 2 is true] Then [do something] End If |
If score = 100 Then Debug.Print «Perfect» ElseIf score > 50 Then Debug.Print «Passed» ElseIf score <= 50 Then Debug.Print «Try again» End If |
Else and ElseIf (Else must come after ElseIf’s) |
If [condition 1 is true] Then [do something] ElseIf [condition 2 is true] Then [do something] Else [do something] End If |
If score = 100 Then Debug.Print «Perfect» ElseIf score > 50 Then Debug.Print «Passed» ElseIf score > 30 Then Debug.Print «Try again» Else Debug.Print «Yikes» End If |
If without Endif (One line only) |
If [condition is true] Then [do something] | If value <= 0 Then value = 0 |
The following code shows a simple example of using the VBA If statement
If Sheet1.Range("A1").Value > 5 Then Debug.Print "Value is greater than five." ElseIf Sheet1.Range("A1").Value < 5 Then Debug.Print "value is less than five." Else Debug.Print "value is equal to five." End If

What is the VBA If Statement
The VBA If statement is used to allow your code to make choices when it is running.
You will often want to make choices based on the data your macros reads.
For example, you may want to read only the students who have marks greater than 70. As you read through each student you would use the If Statement to check the marks of each student.
The important word in the last sentence is check. The If statement is used to check a value and then to perform a task based on the results of that check.
The Test Data and Source Code
We’re going to use the following test data for the code examples in this post:
You can download the test data with all the source code for post plus the solution to the exercise at the end:
Format of the VBA If-Then Statement
The format of the If Then statement is as follows
If [condition is true] Then
The If keyword is followed by a Condition and the keyword Then
Every time you use an If Then statement you must use a matching End If statement.
When the condition evaluates to true, all the lines between If Then and End If are processed.
If [condition is true] Then [lines of code] [lines of code] [lines of code] End If
To make your code more readable it is good practice to indent the lines between the If Then and End If statements.
Indenting Between If and End If
Indenting simply means to move a line of code one tab to the right. The rule of thumb is to indent between start and end statements like
Sub … End Sub
If Then … End If
If Then… ElseIf … Else … Endif
For … Next
Do While … Loop
Select Case … End Case
To indent the code you can highlight the lines to indent and press the Tab key. Pressing Shift + Tab will Outdent the code i.e. move it one tab to the left.
You can also use the icons from the Visual Basic Toolbar to indent/outdent the code
Select code and click icons to indent/outdent
If you look at any code examples on this website you will see that the code is indented.
A Simple If Then Example
The following code prints out the names of all students with marks greater than 50 in French.
' https://excelmacromastery.com/ Sub ReadMarks() Dim i As Long ' Go through the marks columns For i = 2 To 11 ' Check if marks greater than 50 If Sheet1.Range("C" & i).Value > 50 Then ' Print student name to the Immediate Window(Ctrl + G) Debug.Print Sheet1.Range("A" & i).Value & " " & Sheet1.Range("B" & i).Value End If Next End Sub

Using Conditions with the VBA If Statement
The piece of code between the If and the Then keywords is called the condition. A condition is a statement that evaluates to true or false. They are mostly used with Loops and If statements. When you create a condition you use signs like >,<,<>,>=,<=,=.
The following are examples of conditions
Condition | This is true when |
---|---|
x < 5 | x is less than 5 |
x <= 5 | x is less than or equal to 5 |
x > 5 | x is greater than 5 |
x >= 5 | x is greater than or equal to 5 |
x = 5 | x is equal to 5 |
x <> 5 | x does not equal 5 |
x > 5 And x < 10 | x is greater than 5 AND x is less than 10 |
x = 2 Or x >10 | x is equal to 2 OR x is greater than 10 |
Range(«A1») = «John» | Cell A1 contains text «John» |
Range(«A1») <> «John» | Cell A1 does not contain text «John» |
You may have noticed x=5 as a condition. This should not be confused with x=5 when used as an assignment.
When equals is used in a condition it means “is the left side equal to the right side”.
The following table demonstrates how the equals sign is used in conditions and assignments
Using Equals | Statement Type | Meaning |
---|---|---|
Loop Until x = 5 | Condition | Is x equal to 5 |
Do While x = 5 | Condition | Is x equal to 5 |
If x = 5 Then | Condition | Is x equal to 5 |
For x = 1 To 5 | Assignment | Set the value of x to 1, then to 2 etc. |
x = 5 | Assignment | Set the value of x to 5 |
b = 6 = 5 | Assignment and Condition | Assign b to the result of condition 6 = 5 |
x = MyFunc(5,6) | Assignment | Assign x to the value returned from the function |
The last entry in the above table shows a statement with two equals. The first equals sign is the assignment and any following equals signs are conditions.
This might seem confusing at first but think of it like this. Any statement that starts with a variable and an equals is in the following format
[variable] [=] [evaluate this part]
So whatever is on the right of the equals sign is evaluated and the result is placed in the variable. Taking the last three assignments again, you could look at them like this
[x] [=] [5]
[b] [=] [6 = 5]
[x] [=] [MyFunc(5,6)]
Using ElseIf with the VBA If Statement
The ElseIf statement allows you to choose from more than one option. In the following example we print for marks that are in the Distinction or High Distinction range.
' https://excelmacromastery.com/ Sub UseElseIf() If Marks >= 85 Then Debug.Print "High Destinction" ElseIf Marks >= 75 Then Debug.Print "Destinction" End If End Sub
The important thing to understand is that order is important. The If condition is checked first.
If it is true then “High Distinction” is printed and the If statement ends.
If it is false then the code moves to the next ElseIf and checks it condition.
Let’s swap around the If and ElseIf from the last example. The code now look like this
' https://excelmacromastery.com/ Sub UseElseIfWrong() ' This code is incorrect as the ElseIf will never be true If Marks >= 75 Then Debug.Print "Destinction" ElseIf Marks >= 85 Then ' code will never reach here Debug.Print "High Destinction" End If End Sub
In this case we check for a value being over 75 first. We will never print “High Distinction” because if a value is over 85 is will trigger the first if statement.
To avoid these kind of problems we should use two conditions. These help state exactly what you are looking for a remove any confusion. The example below shows how to use these. We will look at more multiple conditions in the section below.
If marks >= 75 And marks < 85 Then Debug.Print "Destinction" ElseIf marks >= 85 And marks <= 100 Then Debug.Print "High Destinction" End If
Let’s expand the original code. You can use as many ElseIf statements as you like. We will add some more to take into account all our mark classifications.
If you want to try out these examples you can download the code from the top of this post.
Using Else With the VBA If Statement
The VBA Else statement is used as a catch all. It basically means “if no conditions were true” or “everything else”. In the previous code example, we didn’t include a print statement for a fail mark. We can add this using Else.
' https://excelmacromastery.com/ Sub UseElse() If Marks >= 85 Then Debug.Print "High Destinction" ElseIf Marks >= 75 Then Debug.Print "Destinction" ElseIf Marks >= 55 Then Debug.Print "Credit" ElseIf Marks >= 40 Then Debug.Print "Pass" Else ' For all other marks Debug.Print "Fail" End If End Sub
So if it is not one of the other types then it is a fail.
Let’s write some code to go through our sample data and print the student and their classification:
' https://excelmacromastery.com/ Sub AddClass() ' get the last row Dim startRow As Long, lastRow As Long startRow = 2 lastRow = Sheet1.Cells(Sheet1.Rows.Count, 1).End(xlUp).Row Dim i As Long, Marks As Long Dim sClass As String ' Go through the marks columns For i = startRow To lastRow Marks = Sheet1.Range("C" & i).Value ' Check marks and classify accordingly If Marks >= 85 Then sClass = "High Destinction" ElseIf Marks >= 75 Then sClass = "Destinction" ElseIf Marks >= 55 Then sClass = "Credit" ElseIf Marks >= 40 Then sClass = "Pass" Else ' For all other marks sClass = "Fail" End If ' Write out the class to column E Sheet1.Range("E" & i).Value = sClass Next End Sub
The results look like this with column E containing the classification of the marks
Results
Remember that you can try these examples for yourself with the code download from the top of this post.
Using Logical Operators with the VBA If Statement
You can have more than one condition in an If Statement. The VBA keywords And and Or allow use of multiple conditions.
These words work in a similar way to how you would use them in English.
Let’s look at our sample data again. We now want to print all the students that got over between 50 and 80 marks.
We use And to add an extra condition. The code is saying: if the mark is greater than or equal 50 and less than 75 then print the student name.
' https://excelmacromastery.com/ Sub CheckMarkRange() Dim i As Long, marks As Long For i = 2 To 11 ' Store marks for current student marks = Sheet1.Range("C" & i).Value ' Check if marks greater than 50 and less than 75 If marks >= 50 And marks < 80 Then ' Print first and last name to Immediate window(Ctrl G) Debug.Print Sheet1.Range("A" & i).Value & Sheet1.Range("B" & i).Value End If Next End Sub

In our next example we want the students who did History or French. So in this case we are saying if the student did History OR if the student did French:
' Description: Uses OR to check the study took History or French. ' Worksheet: Marks ' Output: Result are printed to the Immediate Windows(Ctrl + G) ' https://excelmacromastery.com/vba-if Sub UseOr() ' Get the data range Dim rg As Range Set rg = shMarks.Range("A1").CurrentRegion Dim i As Long, subject As String ' Read through the data For i = 2 To rg.Rows.Count ' Get the subject subject = rg.Cells(i, 4).Value ' Check if subject greater than 50 and less than 80 If subject = "History" Or subject = "French" Then ' Print first name and subject to Immediate window(Ctrl G) Debug.Print rg.Cells(i, 1).Value & " " & rg.Cells(i, 4).Value End If Next End Sub

Using Multiple conditions like this is often a source of errors. The rule of thumb to remember is to keep them as simple as possible.
Using If And
The AND works as follows
Condition 1 | Condition 2 | Result |
TRUE | TRUE | TRUE |
TRUE | FALSE | FALSE |
FALSE | TRUE | FALSE |
FALSE | FALSE | FALSE |
What you will notice is that AND is only true when all conditions are true
Using If Or
The OR keyword works as follows
Condition 1 | Condition 2 | Result |
TRUE | TRUE | TRUE |
TRUE | FALSE | TRUE |
FALSE | TRUE | TRUE |
FALSE | FALSE | FALSE |
What you will notice is that OR is only false when all the conditions are false.
Mixing AND and OR together can make the code difficult to read and lead to errors. Using parenthesis can make the conditions clearer.
' https://excelmacromastery.com/ Sub OrWithAnd() Dim subject As String, marks As Long subject = "History" marks = 5 If (subject = "French" Or subject = "History") And marks >= 6 Then Debug.Print "True" Else Debug.Print "False" End If End Sub
Using If Not
There is also a NOT operator. This returns the opposite result of the condition.
Condition | Result |
TRUE | FALSE |
FALSE | TRUE |
The following two lines of code are equivalent.
If marks < 40 Then If Not marks >= 40 Then
as are
If True Then If Not False Then
and
If False Then If Not True Then
Putting the condition in parenthesis makes the code easier to read
If Not (marks >= 40) Then
A common usage of Not when checking if an object has been set. Take a worksheet for example. Here we declare the worksheet
Dim mySheet As Worksheet ' Some code here
We want to check mySheet is valid before we use it. We can check if it is nothing.
If mySheet Is Nothing Then
There is no way to check if it is something as there is many different ways it could be something. Therefore we use Not with Nothing
If Not mySheet Is Nothing Then
If you find this a bit confusing you can use parenthesis like this
If Not (mySheet Is Nothing) Then
The IIF function
Note that you can download the IIF examples below and all source code from the top of this post.
VBA has an fuction similar to the Excel If function. In Excel you will often use the If function as follows:
=IF(F2=””,””,F1/F2)
The format is
=If(condition, action if true, action if false).
VBA has the IIf statement which works the same way. Let’s look at an example. In the following code we use IIf to check the value of the variable val. If the value is greater than 10 we print true otherwise we print false:
' Description: Using the IIF function to check a number. ' Worksheet: Marks ' Output: Result are printed to the Immediate Windows(Ctrl + G) ' https://excelmacromastery.com/vba-if Sub CheckNumberIIF() Dim result As Boolean Dim number As Long ' Prints True number = 11 result = IIf(number > 10, True, False) Debug.Print "Number " & number & " greater than 10 is " & result ' Prints false number = 5 result = IIf(number > 10, True, False) Debug.Print "Number " & number & " greater than 10 is " & result End Sub
In our next example we want to print out Pass or Fail beside each student depending on their marks. In the first piece of code we will use the normal VBA If statement to do this:
' https://excelmacromastery.com/ Sub CheckMarkRange() Dim i As Long, marks As Long For i = 2 To 11 ' Store marks for current student marks = Sheet1.Range("C" & i).Value ' Check if student passes or fails If marks >= 40 Then ' Write out names to to Column F Sheet1.Range("E" & i) = "Pass" Else Sheet1.Range("E" & i) = "Fail" End If Next End Sub
In the next piece of code we will use the IIf function. You can see that the code is much neater here:
' Description: Using the IIF function to check marks. ' Worksheet: Marks ' Output: Result are printed to the Immediate Windows(Ctrl + G) ' https://excelmacromastery.com/vba-if Sub CheckMarkRange() ' Get the data range Dim rg As Range Set rg = shMarks.Range("A1").CurrentRegion Dim i As Long, marks As Long, result As String ' Go through the marks columns For i = 2 To rg.Rows.Count ' Store marks for current student marks = rg.Cells(i, 3).Value ' Check if student passes or fails result = IIf(marks >= 40, "Pass", "Fail") ' Print the name and result Debug.Print rg.Cells(i, 1).Value, result Next End Sub
You can see the IIf function is very useful for simple cases where you are dealing with two possible options.
Using Nested IIf
You can also nest IIf statements like in Excel. This means using the result of one IIf with another. Let’s add another result type to our previous examples. Now we want to print Distinction, Pass or Fail for each student.
Using the normal VBA we would do it like this
' https://excelmacromastery.com/ Sub CheckResultType2() Dim i As Long, marks As Long For i = 2 To 11 ' Store marks for current student marks = Sheet1.Range("C" & i).Value If marks >= 75 Then Sheet1.Range("E" & i).Value = "Distinction" ElseIf marks >= 40 Then ' Write out names to to Column F Sheet1.Range("E" & i).Value = "Pass" Else Sheet1.Range("E" & i).Value = "Fail" End If Next End Sub
Using nested IIfs we could do it like this:
' Description: Using a nested IIF function to check marks. ' Worksheet: Marks ' Output: Result are printed to the Immediate Windows(Ctrl + G) ' https://excelmacromastery.com/vba-if Sub UsingNestedIIF() ' Get the data range Dim rg As Range Set rg = shMarks.Range("A1").CurrentRegion Dim i As Long, marks As Long, result As String ' Go through the marks columns For i = 2 To rg.Rows.Count marks = rg.Cells(i, 3).Value result = IIf(marks >= 55, "Credit", IIf(marks >= 40, "Pass", "Fail")) Debug.Print marks, result Next i End Sub
Using nested IIf is fine in simple cases like this. The code is simple to read and therefore not likely to have errors.
What to Watch Out For
It is important to understand that the IIf function always evaluates both the True and False parts of the statement regardless of the condition.
In the following example we want to divide by marks when it does not equal zero. If it equals zero we want to return zero.
marks = 0 total = IIf(marks = 0, 0, 60 / marks)
However, when marks is zero the code will give a “Divide by zero” error. This is because it evaluates both the True and False statements. The False statement here i.e. (60 / Marks) evaluates to an error because marks is zero.
If we use a normal IF statement it will only run the appropriate line.
marks = 0 If marks = 0 Then 'Only executes this line when marks is zero total = 0 Else 'Only executes this line when marks is Not zero total = 60 / marks End If
What this also means is that if you have Functions for True and False then both will be executed. So IIF will run both Functions even though it only uses one return value. For example
'Both Functions will be executed every time total = IIf(marks = 0, Func1, Func2)
(Thanks to David for pointing out this behaviour in the comments)
If Versus IIf
So which is better?
You can see for this case that IIf is shorter to write and neater. However if the conditions get complicated you are better off using the normal If statement. A disadvantage of IIf is that it is not well known so other users may not understand it as well as code written with a normal if statement.
Also as we discussed in the last section IIF always evaluates the True and False parts so if you are dealing with a lot of data the IF statement would be faster.
My rule of thumb is to use IIf when it will be simple to read and doesn’t require function calls. For more complex cases use the normal If statement.
Using Select Case
The Select Case statement is an alternative way to write an If statment with lots of ElseIf’s. You will find this type of statement in most popular programming languages where it is called the Switch statement. For example Java, C#, C++ and Javascript all have a switch statement.
The format is
Select Case [variable] Case [condition 1] Case [condition 2] Case [condition n] Case Else End Select
Let’s take our AddClass example from above and rewrite it using a Select Case statement.
' https://excelmacromastery.com/ Sub AddClass() ' get the last row Dim startRow As Long, lastRow As Long startRow = 2 lastRow = Sheet1.Cells(Sheet1.Rows.Count, 1).End(xlUp).Row Dim i As Long, Marks As Long Dim sClass As String ' Go through the marks columns For i = startRow To lastRow Marks = Sheet1.Range("C" & i).Value ' Check marks and classify accordingly If Marks >= 85 Then sClass = "High Destinction" ElseIf Marks >= 75 Then sClass = "Destinction" ElseIf Marks >= 55 Then sClass = "Credit" ElseIf Marks >= 40 Then sClass = "Pass" Else ' For all other marks sClass = "Fail" End If ' Write out the class to column E Sheet1.Range("E" & i).Value = sClass Next End Sub
The following is the same code using a Select Case statement. The main thing you will notice is that we use “Case 85 to 100” rather than “marks >=85 And marks <=100”.
' https://excelmacromastery.com/ Sub AddClassWithSelect() ' get the first and last row Dim firstRow As Long, lastRow As Long firstRow = 2 lastRow = Cells(Cells.Rows.Count, 1).End(xlUp).Row Dim i As Long, marks As Long Dim sClass As String ' Go through the marks columns For i = firstRow To lastRow marks = Sheet1.Range("C" & i).Value ' Check marks and classify accordingly Select Case marks Case 85 To 100 sClass = "High Destinction" Case 75 To 84 sClass = "Destinction" Case 55 To 74 sClass = "Credit" Case 40 To 54 sClass = "Pass" Case Else ' For all other marks sClass = "Fail" End Select ' Write out the class to column E Sheet1.Range("E" & i).Value = sClass Next End Sub
Using Case Is
You could rewrite the select statement in the same format as the original ElseIf. You can use Is with Case.
' https://excelmacromastery.com/ Select Case marks Case Is >= 85 sClass = "High Destinction" Case Is >= 75 sClass = "Destinction" Case Is >= 55 sClass = "Credit" Case Is >= 40 sClass = "Pass" Case Else ' For all other marks sClass = "Fail" End Select
You can use Is to check for multiple values. In the following code we are checking if marks equals 5, 7 or 9.

VBA Logical Operators: AND, OR, NOT, IF NOT in Excel VBA
Updated January 20, 2023
Excel VBA Logical Operators
Let’s say you want to process a customer order. For that, you want to first check to see if the ordered product exists or not. If it does, you also want to check if the quantity on hand is enough. Logical operators come in handy in such cases. Logical operators are used to evaluate more than one condition.
The main Excel VBA logical operators AND, OR, NOT are listed in the table below:
S/N | Operator | Description | Example | Output |
---|---|---|---|---|
1 | AND | AND: This is used to combine more than one condition. If all the conditions are true, AND evaluates to true. If any of the condition is false, AND evaluates to false | If true = true AND false = true THEN | false |
2 | OR | OR: This is used to combine more than one condition. If any of the conditions evaluate to true, OR returns true. If all of them are false, OR returns false | If true = true OR true = false THEN | true |
3 | NOT | NOT: This one works like an inverse function. If the condition is true, it returns false, and if a condition is false, it returns true. | If NOT (true) Then | false |

VBA IF OR (Test Multiple Conditions)
You can use the OR operator with the VBA IF statement to test multiple conditions. When you use it, it allows you to test two or more conditions simultaneously and returns true if any of those conditions are true. But if all the conditions are false only then it returns false in the result.
Use OR with IF
- First, start the IF statement with the “IF” keyword.
- After that, specify the first condition that you want to test.
- Next, use the OR keyword to specify the second condition.
- In the end, specify the second condition that you want to test.
To have a better understanding let’s see an example.
If you look at the above example, we have specified two conditions one if (1 = 1) and the second is (2
Now let’s see if both conditions are false, let me use a different code here.
In the above code, both conditions are false, and when you run this code, it executes the line of code that we have specified if the result is false.
Multiple Conditions with IF OR
In the same way, you can also test more than two conditions at the same time. Let’s continue the above example and add the third condition to it.
Now we have three conditions to test, and we have used the OR after the second condition to specify the third condition. As you learned above that when you use OR, any of the conditions need to be true to get true in the result. When you run this code, it executes the line of code that we have specified for the true.
And if all the conditions are false, just like you have in the following code, it returns false.

VBA If – And, Or, Not
In this Article
This article will demonstrate how to use the VBA If statement with And, Or and Not.
When we us an IF statement in Excel VBA, the statement will execute a line of code if the condition you are testing is true.
- We can use AND statement and OR statements in conjunction with IF statements to test for more than one condition and direct the code accordingly.
- We can also use a NOT statement with an IF statement to check if the condition is NOT true – it basically is the inverse of the IF statement when used alone.
IF…AND
We can use the IF…AND combination of logical operators when we wish to test for more than one condition where all the conditions need to be true for the next line of code to execute.
For example, consider the following sheet:
To check if the Profit is over $5,000, we can run the following macro:
This macro will check that the cell C5 is greater or equal to $10,000 AND check that the cell B6 is less than $5,000. If these conditions are BOTH true, it will show the message box.
If we amend the macro to check if C5 is just greater than $10,000, then the profit would not be achieved!
We can use the IF…OR combination of logical operators when we wish to test for more than one condition where only one of the conditions needs to be true for the next line of code to execute.
The format for this is almost identical to the IF…AND example above.
However, with this macro, because we are using an IF …OR statement, only one of the conditions needs to be true.
IF NOT…
IF..NOT changes the IF statement around – it will check to see if the condition is NOT true rather than checking to see if the condition is true.
In this example above, the IF statement is checking to see if the value in C5 is NOT smaller than 10000.
Therefore this line of code:
and this this line of code:
are testing for the same thing!

VBA IF OR
IF OR is not a single statement. Rather, these are two logical functions used together in VBA when we have more than one criteria to check. When we use the IF statement, if any criteria meet, we get the TRUE result. OR statement is used between the two criteria of the IF statement.
IF OR Function in VBA
Logical functions are the heart of any criteria-based calculations. The IF function is the most popular logical function, be it a worksheet function or a VBA function because it serves excellently for our needs. But one more logical function, OR in excel, is the most underrated. It is also important to master when it comes to solving complex calculations. This article will take you through the VBA IF OR function in detail. Read the full article to get the function in detail.

How to Use IF with OR Function in VBA?
We will show you a simple example of using the IF OR function in VBA.
A combination of logical functions is the best pair in Excel. However, combining many logical formulas inside the other logical formula suggests that calculation requires many conditions to test.
Now, look at the syntax of the IF OR function in VBA.
It is the same as we saw in the worksheet example. For a better understanding, look at the below example.
We have the previous month’s price, the last 6-month average price, and the current monthly price here.
To decide whether to buy the product, we need to do some tests here, and those tests are.
If the Current Price is less than or equal to any of the other two prices, we should get the result as “Buy” or else should get the result as “Do Not Buy.”
Step 1: Open the IF condition inside the Sub procedure.
Code:
Step 2: Inside the IF condition, apply the first logical test as Range(“D2”).Value
Step 3: The first logical condition completes. Now, open OR statement.
Code:
Step 4: Now, apply the second logical condition as Range(“D2”).Value
Step 5: We are done with the logical tests here. After the logical tests, put the word “Then.”
Code:
Step 6: In the next line, write what the result should be if the logical test Logical Test A logical test in Excel results in an analytical output, either true or false. The equals to operator, “=,” is the most commonly used logical test. read more is TRUE. If the condition is TRUE, we need the result as “Buy” in cell E2.
Code:
Step 7: If the result is FALSE, we should get the result as “Do Not Buy.” So in the next line, put “Else” and write the code in the next line.
Code:
Step 8: Close the IF statement with “End If.”
Code:
We complete the coding part.
Let us run this code using F5 or manually through the run option and see the result in cell E2.
We got the result as “Buy” because the current monthly price of Apple is less than the price of both “Previous Month” as well as “6 Month Average Price”.
IF OR VBA Function with Loops (Advanced)
Once you understand the formula, try to use it with a larger number of cells. In the case of a larger number of cells, we cannot write any line of code, so we need to use VBA loops Use VBA Loops A VBA loop in excel is an instruction to run a code or repeat an action multiple times. read more .
We have added a few more lines for the above data set.
We need to use the For Next Loop here.
Just keep the current code as it is.
Declare the variable as an Integer.
Now, open For Next Loop from 2 to 9.
For example, Range (“D2”).Value should be Range (“D” & k).Value
Now, run the code. First, we should get the status in all the cells.
You can copy the code below.

VBA If, ElseIf, Else (Ultimate Guide to If Statements)
In this Article
VBA If Statement
If Then
VBA If Statements allow you to test if expressions are TRUE or FALSE, running different code based on the results.
Let’s look at a simple example:
This tests if the value in Range A2 is greater than 0. If so, setting Range B2 equal to “Positive”
Note: When testing conditions we will use the =, >, , = comparison operators. We will discuss them in more detail later in the article.
Here is the syntax for a simple one-line If statement:
To make it easier to read, you can use a Line Continuation character (underscore) to expand the If Statements to two lines (as we did in the above picture):
End If
The above “single-line” if statement works well when you are testing one condition. But as your IF Statements become more complicated with multiple conditions, you will need to add an “End If” to the end of the if statement:
Here the syntax is:
The End If signifies the end of the if statement.
Now let’s add in an ElseIF:
ElseIF – Multiple Conditions
The ElseIf is added to an existing If statement. ElseIf tests if a condition is met ONLY if the previous conditions have not been met.
In the previous example we tested if a cell value is positive. Now we will also test if the cell value is negative with an ElseIf:
You can use multiple ElseIfs to test for multiple conditions:
Now we will add an Else:
The Else will run if no other previous conditions have been met.
We will finish our example by using an Else to indicate that if the cell value is not positive or negative, then it must be zero:
If-Else
The most common type of If statement is a simple If-Else:
Nested IFs
You can also “nest” if statements inside of each other.

IF – Or, And, Xor, Not
Next we will discuss the logical operators: Or, And, Xor, Not.
If Or
The Or operator tests if at least one condition is met.
The following code will test if the value in Range A2 is less than 5,000 or greater than 10,000:
You can include multiple Ors in one line:
If you are going to use multiple Ors, it’s recommended to use a line continuation character to make your code easier to read:
If And
The And operator allows you to test if ALL conditions are met.
If Xor
The Xor operator allows you to test if exactly one condition is met. If zero conditions are met Xor will return FALSE, If two or more conditions are met, Xor will also return false.
I’ve rarely seen Xor used in VBA programming.
If Not
The Not operator is used to convert FALSE to TRUE or TRUE To FALSE:
Notice that the Not operator requires parenthesis surrounding the expression to switch.
The Not operator can also be applied to If statements:
If Comparisons
When making comparisons, you will usually use one of the comparison operators:
Comparison Operator | Explanation | |||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|
= | Equal to | |||||||||||
<> | Not Equal to | |||||||||||
> | Greater than | |||||||||||
>= | Greater than or Equal to | |||||||||||
If – Boolean Function
When build expressions for If Statements, you can also use any function that generates TRUE or False. VBA has a few of these functions:
They can be called like this: Excel also has many additional functions that can be called using WorksheetFunction. Here’s an example of the Excel IsText Function: You can also create your own User Defined Functions (UDFs). Below we will create a simple Boolean function that returns TRUE. Then we will call that function in our If statement: Comparing TextYou can also compare text similar to comparing numbers: When comparing text, you must be mindful of the “Case” (upper or lower). By default, VBA considers letters with different cases as non-matching. In other words, “A” <> “a”. If you’d like VBA to ignore case, you must add the Option Compare Text declaration to the top of your module: After making that declaration “A” = “a”: VBA If LikeThe VBA Like Operator allows you to make inexact comparisons of text. Click the “Like Operator” link to learn more, but we will show a basic example below: Here we’re using an asterisk “*” wildcard. The * stands for any number of any characters. So the above If statement will return TRUE. The Like operator is an extremely powerful, but often under-used tool for dealing with text. If LoopsVBA Loops allow you to repeat actions. Combining IF-ELSEs with Loops is a great way to quickly process many calculations. Continuing with our Positive / Negative example, we will add a For Each Loop to loop through a range of cells: If Else ExamplesNow we will go over some more specific examples. Check if Cell is EmptyThis code will check if a cell is empty. If it’s empty it will ignore the cell. If it’s not empty it will output the cell value to the cell to the right: Check if Cell Contains Specific TextThe Instr Function tests if a string of text is found in another string. Use it with an If statement to check if a cell contains specific text: Check if cell contains textThis code will test if a cell is text: If GotoYou can use the result of an If statement to “Go to” another section of code. Delete Row if Cell is BlankIf MessageBox Yes / NoWith VBA Message Boxes you’re able to ask the user to select from several options. The Yes/No Message Box asks the user to select Yes or No. You can add a Yes / No Message Box to a procedure to ask the user if they would like to continue running the procedure or not. You handle the user’s input using an If statement. Here is the Yes/No Message Box in practice: VBA If, ElseIf, Else in Access VBAThe If, ElseIf and Else functions work exactly the same in Access VBA as in Excel VBA.

We use the IF statement in Excel to test one condition and return one value if the condition is met and another if the condition is not met.
However, we use multiple or nested IF statements when evaluating numerous conditions in a specific order to return different results.
This tutorial shows four examples of using nested IF statements in Excel and gives five alternatives to using multiple IF statements in Excel.
General Syntax of Nested IF Statements (Multiple IF Statements)
The general syntax for nested IF statements is as follows:
=IF(Condition1, Value_if_true1, IF(Condition2, Value_if_true2, IF(Condition3, Value_if_true3, Value_if_false)))
This formula tests the first condition; if true, it returns the first value.
If the first condition is false, the formula moves to the second condition and returns the second value if it’s true.
Each subsequent IF function is incorporated into the value_if_false argument of the previous IF function.
This process continues until all conditions have been evaluated, and the formula returns the final value if none of the conditions is true.
The maximum number of nested IF statements allowed in Excel is 64.
Now, look at the following four examples of how to use nested IF statements in Excel.
Example #1: Use Multiple IF Statements to Assign Letter Grades Based on Numeric Scores
Let’s consider the following dataset showing some students’ scores on a Math test.
We want to use nested IF statements to assign student letter grades based on their scores.
We use the following steps:
- Select cell C2 and type in the below formula:
=IF(B2>=90,"A",IF(B2>=80,"B",IF(B2>=70,"C",IF(B2>=60,"D","F"))))
- Click Enter in the cell to get the result of the formula in the cell.
- Copy the formula for the rest of the cells in the column
The assigned letter grades appear in column C.
Explanation of the formula
=IF(B2>=90,”A”,IF(B2>=80,”B”,IF(B2>=70,”C”,IF(B2>=60,”D”,”F”))))
This formula evaluates the value in cell B2 and assigns an “A” if the value is 90 or greater, a “B” if the value is between 80 and 89, a “C” if the value is between 70 and 79, a “D” if the value is between 60 and 69, and an “F” if the value is less than 60.
Notice that it can be challenging to keep track of which parentheses go with which arguments in nested IF functions.
Therefore, as we enter the formula, Excel uses different colors for the parentheses at each level of the nested IF functions to make it easier to see which parts of the formula belong together.

Example #2: Use Multiple IF Statements to Calculate Commission Based on Sales Volume
Here’s the dataset showing the sales of specific salespeople in a particular month.
We want to use multiple IF statements to calculate the tiered commission for the salespeople based on their sales volume.
We proceed as follows:
- Select cell C2 and enter the following formula:
=IF(B2>=40000, B2*0.14,IF(B2>=20000,B2*0.12,IF(B2>=10000,B2*0.105,IF(B2>0,B2*0.08,0))))
- Press the Enter key to get the result of the formula.
- Double-click or drag the Fill Handle to copy the formula down the column.
The commission for each salesperson is displayed in column D.
Explanation of the formula
=IF(B2>=40000, B2*0.14,IF(B2>=20000,B2*0.12,IF(B2>=10000,B2*0.105,IF(B2>0,B2*0.08,0))))
This formula evaluates the value in cell B2 and then does the following:
- If the value in cell B2 is greater than or equal to 40,000, the figure is multiplied by 14% (0.14).
- If the figure in cell B2 is less than 40,000 but greater than or equal to 20,000, the value is multiplied by 12% (0.12).
- If the number in cell B2 is less than 20,000 but greater than or equal to 10,000, the figure is multiplied by 10.5% (0.105).
- If the value in cell B2 is less than 10,000 but greater than 0 (zero), the number is multiplied by 8% (0.08).
- If the value in cell B2 is 0 (zero), 0 (zero) is returned.
Example #3: Use Multiple IF Statements to Assign Sales Performance Rating Based On Sales Target Achievement
The following is a dataset showing regional sales data of a specific technology company in a particular year.
We want to use multiple IF statements to assign a sales performance rating to each region based on their sales target achievement.
We use the following steps:
- Select cell C2 and type in the below formula:
=IF(B2>500000, "Excellent", IF(B2>400000, "Good", IF(B2>275000, "Average", "Poor")))
- Click Enter on the Formula bar.
- Drag or double-click the Fill Handle to copy the formula down the column.
The performance ratings of the regions are shown in column C.
Explanation of the formula
=IF(B2>500000, “Excellent”, IF(B2>400000, “Good”, IF(B2>275000, “Average”, “Poor”)))
In this formula, if the sales target in cell B2 is greater than 500,000, the formula returns “Excellent.”
If it’s between 400,000 and 500,000, the formula returns “Good.”
If it’s between 275,000 and 400,000, the formula returns “Average.” And if it’s below 275,000, the formula returns “Poor.”
Example #4: Use Multiple IF Statements in Excel to Check For Errors and Return Error Messages
Suppose we have the following dataset of students’ English test scores. Some scores are less than 0 or greater than 100, and there are no scores in some cases.
We want to use nested IF statements to check for scores in column B and display error messages in column C if there are no scores or the scores are less than 0 or greater than 100.
If the score in column B is valid, we want the formula to return an empty string in column C.
Here are the steps to follow:
- Select cell C2 and enter the following formula:
=IF(OR(B2<0,B2>100),"Score out of range",IF(ISBLANK(B2),"Invalid score",""))
- Click Enter on the Formula bar.
- Drag the Fill Handle to copy the formula down the column.
The error messages are shown in column C.
Explanation of the formula
=IF(OR(B2<0,B2>100),”Score out of range”,IF(ISBLANK(B2),”Invalid score”,””))
This formula uses the OR function to check if the score in cell B2 is less than 0 or greater than 100, and if it is, it returns the error message “Score out of range.”
The formula also uses the ISBLANK function to check if cell B2 is blank, and if it is, it returns the error message “Invalid score.”
If there is no error, the formula returns an empty string, meaning no message is displayed in column B.
Alternatives to Using Multiple IF Statements in Excel
Formulas using nested IF statements can become difficult to read and manage if we have more than a few conditions to test.
In addition, if we exceed the maximum allowed limit of 64 nested IF statements, we will get an error message.
Fortunately, Excel offers alternative ways to use instead of nested IF functions, especially when we need to test more than a few conditions.
We present the alternative ways in this tutorial.
Alternative #1: Use the IFS Function
The IFS function tests whether one or more conditions are met and returns a value corresponding to the first TRUE condition.
Before the release of the IFS function in 2018 as part of the Excel 365 update, the only way to test multiple conditions and return a corresponding value in Excel was to use nested IF statements.
However, multiple IF statements have the downside of resulting in unwieldy formulas that are difficult to read and maintain.
In some situations, the IFS function is designed to replace the need for multiple IF functions.
The syntax of the IFS function is more straightforward and easier to read than nested IF statements, and it can handle up to 127 conditions.
Here’s an example:
Let’s consider the following dataset showing some students’ scores on a Math test.
We want to use the IFS function to assign letter grades to the students based on their scores.
We use the following steps:
- Select cell C2 and type in the below formula:
=IFS(B2>=90, "A", B2>=80, "B", B2>=70, "C", B2>=60, "D", B2<60, "F")
- Click Enter on the Formula bar.
- Drag or double-click the Fill Handle to copy the formula down the column.
The student’s letter grades are shown in column C.
Explanation of the formula
=IFS(B2>=90, “A”, B2>=80, “B”, B2>=70, “C”, B2>=60, “D”, B2<60, “F”)
This formula tests the score in cell B2 against each condition and returns the corresponding grade letter when the condition is true.
Limitation of IFS Function
The IFS function in Excel is designed to simplify complex nested IF statements.
However, there are situations where the IFS function may not be able to replace nested IF functions completely.
One such situation is when you must calculate or operate based on a condition or set of conditions.
While the IFS function can return a value or text string based on a condition, it cannot perform calculations or operations on that value like nested IF statements.
Another situation where the IFS function may be less useful is when you need to test for a range of conditions rather than just a specific set.
This is because the IFS function requires you to specify each condition and corresponding result separately, which can become cumbersome if you have many conditions to test—in contrast, nested IF statements allow you to test for a range of conditions using logical operators like AND and OR.
The IFS function is a powerful tool for simplifying complex logical tests in Excel.
However, there may be situations where nested IF statements are more appropriate for your needs.
We recommend that you consider both options and choose the one that best fits the specific requirements of your task.
Alternative #2: Use Nested IF Functions
We can use multiple IFS functions in a formula if we have more than one condition to test.
For example, let’s say we have the following dataset of student names and scores on a Physics test in columns A and B.
We want to assign a letter grade to each score and include a pass or fail designation based on whether the score is above or below 75.
Here are the steps to use:
- Select cell C2 and enter the following formula
=IFS(B2>=90,"A",B2>=80,"B",B2>=70,"C",B2>=60,"D",B2<60,"F")&" "&IFS(B2>=75,"Pass",B2<75,"Fail")
- Click Enter on the Formula bar.
- Drag or double-click the Fill Handle to copy the formula down the column.
The letter grade and designation of the student scores are displayed in column C.
Explanation of the formula
=IFS(B2>=90,”A”,B2>=80,”B”,B2>=70,”C”,B2>=60,”D”,B2<60,”F”)&” “&IFS(B2>=75,”Pass”,B2<75,”Fail”)
This formula uses the first IFS function to assign a letter grade based on the score in column A and the second IFS function to give a pass/fail designation based on the score in column A.
The two IFS functions are combined using the ampersand (&) operator to create a single text string that displays each score’s letter grade and pass/fail designation.
Alternative #3: Use the Combination of CHOOSE and XMATCH Functions
The CHOOSE function selects a value or action from a value list based on an index number.
The XMATCH function locates and returns the relative position of an item in an array. We can combine these functions in a formula instead of nested IF functions.
Here’s an example:
Suppose we have the following dataset showing some students’ scores and letter grades on a Biology test.
We want to use a formula combining the CHOOSE and XMATCH functions to assign corresponding grade points in column D to each letter grade.
We use the following steps:
- Select cell D2 and type in the below formula:
=CHOOSE(XMATCH(C2,{"F","E","D","C","B","A"},0),0,1,2,3,4,5)
- Click Enter on the Formula bar.
- Drag or double-click the Fill Handle to copy the formula down the column.
The grade points for each student are displayed in column D.
Explanation of the formula
=CHOOSE(XMATCH(C2,{“F”,”E”,”D”,”C”,”B”,”A”},0),0,1,2,3,4,5)
This formula applies the XMATCH function to find the position of the letter grade in the array {“F”,”E”,”D”,”C”,”B”,”A”}, and then uses the CHOOSE function to return the corresponding grade points.
Alternative #4: Use the VLOOKUP Function
The VLOOKUP function looks for a value in the leftmost column of a table and then returns a value in the same row from a specified column.
We can use the VLOOKUP function instead of nested IF functions in Excel.
The following is an example of using the VLOOKUP function instead of nested IF functions in Excel:
Suppose we have the following dataset showing some students’ scores and letter grades on a Biology test.
We want to use the VLOOKUP function to assign grade points to each student’s letter grade in column D.
We use the steps below:
- Create a table that lists the grades and their corresponding grade points in cell range F1:G7.
- In cell D2, type the following formula:
=VLOOKUP(C2,$F$2:$G$7,2,FALSE)
Note: Use the dollar signs to lock down the cell range F2:G7.
- Click Enter on the Formula bar.
- Drag or double-click the Fill Handle to copy the formula down the column.
The grade points for each student appear in column D.
Explanation of the formula
=VLOOKUP(C2,$F$2:$G$7,2,FALSE)
This formula uses the VLOOKUP function to look up the grade in cell C2 in the table in F2:G7 and return the corresponding grade point in the second column (i.e., column G).
The “FALSE” argument ensures that an exact match is required.
Alternative #5: Use a User-Defined Function
If you need to test more than a few conditions, consider creating a User Defined Function in VBA that can handle many conditions.
Here’s an example of using VBA code to replace nested IF functions in Excel:
Suppose we have the following dataset showing the sales of specific salespeople in a particular month.
We want to use a User Defined Function to calculate the commission for each salesperson based on the following rates:
- If the total sales are less than $10,000, the commission rate is 8%.
- If the total sales are equal to or greater than $10,000 but less than $20,000, the commission rate is 10.5%.
- If the total sales are equal to or greater than $20,000 but less than $40,000, the commission rate is 12%.
- If the sales are equal to or greater than $40,000, the commission rate is 14%
We use the following steps:
- Open the worksheet containing the sales dataset.
- Press Alt + F11 to launch the Visual Basic Editor.
- Click Insert on the menu bar and choose Module to insert a new module.
- Enter the following VBA code.
'Code developed by Steve Scott from https://spreadsheetplanet.com
Function COMMISSION(Sales As Double) As Double
Const Rate1 = 0.08
Const Rate2 = 0.105
Const Rate3 = 0.12
Const Rate4 = 0.14
'Calculate sales commissions
Select Case Sales
Case 0 To 9999.99: COMMISSION = Sales * Rate1
Case 10000 To 19999.99: COMMISSION = Sales * Rate2
Case 20000 To 39999.99: COMMISSION = Sales * Rate3
Case Is >= 40000: COMMISSION = Sales * Rate4
End Select
End Function
- Save the function procedure and the workbook as a Macro-Enabled Workbook.
- Press Alt + F11 to switch to the active worksheet with the sales dataset.
- Select cell C2 and enter the following formula:
=COMMISSION(B2)
- Click Enter on the Formula bar.
- Drag or double-click the Fill Handle to copy the formula down the column.
The commission for each salesperson is displayed in column C.
This VBA function takes the sales amount as an argument and returns the corresponding commission.
The User-Defined Function is a much simpler and easier-to-read solution than using nested IF functions.

Краткое руководство по VBA If Statement
Описание | Формат | Пример |
If Then | If [условие верно] Then [действие] End If |
If score = 100 Then Debug.Print «Отлично» End If |
If Else | If [условие верно] Then [действие] Else [действие] End If |
If score = 100 Then Debug.Print «Отлично» Else Debug.Print «Попробуй снова» End If |
If ElseIf | If [1 условие верно] Then [действие] ElseIf [2 условие верно] Then [действие] End If |
If score = 100 Then Debug.Print «Отлично» ElseIf score > 50 Then Debug.Print «Пройдено» ElseIf score <= 50 Then Debug.Print «Попробуй снова» End If |
Else и ElseIf (Else должно идти после ElseIf’s) |
If [1 условие верно] Then [действие] ElseIf [2 условие верно] Then [действие] Else [действие] End If |
If score = 100 Then Debug.Print «Отлично» ElseIf score > 50 Then Debug.Print «Пройдено» ElseIf score > 30 Then Debug.Print «Попробуй снова» Else Debug.Print «Ой» End If |
If без Endif (Только одна строка) |
If [условие верно] Then [действие] |
If value <= 0 Then value = 0 |
В следующем коде показан простой пример использования
оператора VBA If
If Sheet1.Range("A1").Value > 5 Then Debug.Print "Значение больше 5." ElseIf Sheet1.Range("A1").Value < 5 Then Debug.Print "Значение меньше 5." Else Debug.Print "Значение равно 5." End If
Что такое IF и зачем оно тебе?
Оператор VBA If используется, чтобы позволить вашему коду
делать выбор, когда он выполняется.
Вам часто захочется сделать выбор на основе данных, которые
читает ваш макрос.
Например, вы можете захотеть читать только тех учеников, у
которых оценки выше 70. Когда вы читаете каждого учащегося, вы можете
использовать инструкцию If для проверки отметок каждого учащегося.
Важным словом в последнем предложении является проверка. Оператор
If используется для проверки значения, а затем для выполнения задачи на основе
результатов этой проверки.
Тестовые данные
Мы собираемся использовать следующие тестовые данные для
примеров кода в этом посте.
Формат операторов VBA If Then
Формат оператора If Then следующий
За ключевым словом If следуют условие и ключевое слово Then
Каждый раз, когда вы используете оператор If Then, вы должны использовать соответствующий оператор End If.
Когда условие оценивается как истинное, обрабатываются все
строки между If Then и End If.
If [условие верно] Then [строки кода] [строки кода] [строки кода] End If
Чтобы сделать ваш код более читабельным, рекомендуется
делать отступы между операторами If Then и End If.
Отступ между If и End If
Отступ означает просто переместить строку кода на одну вкладку вправо. Правило большого пальца состоит в том, чтобы сделать отступ между начальным и конечным операторами, такими как:
Sub … End Sub
If Then … End If
If Then… ElseIf … Else … Endif
For … Next
Do While … Loop
Select Case … End Case
Для отступа в коде вы можете выделить строки для отступа и нажать клавишу Tab. Нажатие клавиш Shift + Tab сделает отступ кода, т.е. переместит его на одну вкладку влево.
Вы также можете использовать значки на панели инструментов Visual Basic для отступа кода.
Если вы посмотрите на примеры кода на этом сайте, вы увидите, что код имеет отступ.
Простой пример If Then
Следующий код выводит имена всех студентов с баллами более 50.
Sub ChitatOcenki() Dim i As Long ' Пройдите столбцы отметок For i = 2 To 11 ' Проверьте, больше ли баллов,чем 50 If Sheet1.Range("C" & i).Value > 50 Then ' Напечатайте имя студента в «Immediate Window» (Ctrl + G) Debug.Print Sheet1.Range("A" & i).Value & " " & Sheet1.Range("B" & i).Value End If Next End Sub
Результаты:
- Василий Кочин
- Максим Бородин
- Дмитрий Маренин
- Олеся Клюева
- Евгений Яшин
Поэкспериментируйте с этим примером и проверьте значение или знак > и посмотрите, как изменились результаты.
Условия IF
Часть кода между ключевыми словами If и Then называется условием. Условие — это утверждение, которое оценивается как истинное или ложное. Они в основном используются с операторами Loops и If. При создании условия вы используете такие знаки, как «>, <, <>,> =, <=, =».
Ниже приведены примеры условий:
Условие | Это верно, когда |
x < 5 | x меньше,чем 5 |
x <= 5 | x меньше, либо равен 5 |
x > 5 | x больше, чем 5 |
x >= 5 | x больше, либо равен 5 |
x = 5 | x равен 5 |
x <> 5 | x не равен 5 |
x > 5 And x < 10 | x больше, чем 5 И x меньше, чем 10 |
x = 2 Or x >10 | x равен 2 ИЛИ x больше,чем 10 |
Range(«A1») = «Иван» | Ячейка A1 содержит текст «Иван» |
Range(«A1») <> «Иван» | Ячейка A1 не содержит текст «Иван» |
Вы могли заметить x = 5, как условие. Не стоит путать с х = 5, при использовании в качестве назначения.
Когда в условии используется «=», это означает, что «левая сторона равна правой стороне».
В следующей таблице показано, как знак равенства используется
в условиях и присваиваниях.
Использование «=» | Тип | Значение |
Loop Until x = 5 | Условие | Равен ли x пяти |
Do While x = 5 | Условие | Равен ли x пяти |
If x = 5 Then | Условие | Равен ли x пяти |
For x = 1 To 5 | Присваивание | Установите значение х = 1, потом = 2 и т.д. |
x = 5 | Присваивание | Установите х до 5 |
b = 6 = 5 | Присваивание и условие |
Присвойте b результату условия 6 = 5 |
x = MyFunc(5,6) | Присваивание | Присвойте х значение, возвращаемое функцией |
Последняя запись в приведенной выше таблице показывает
оператор с двумя равными. Первый знак равенства — это присвоение, а любые
последующие знаки равенства — это условия.
Поначалу это может показаться странным, но подумайте об этом
так. Любое утверждение, начинающееся с переменной и равно, имеет следующий
формат
[переменная] [=] [оценить эту часть]
Поэтому все, что находится справа от знака равенства, оценивается и результат помещается в переменную. Посмотрите на последние три строки таблицы, как:
[x] [=] [5]
[b] [=] [6 = 5]
[x] [=] [MyFunc (5,6)]
Использование If ElseIf
Инструкция ElseIf позволяет вам выбирать из нескольких вариантов. В следующем примере мы печатаем баллы, которые находятся в диапазоне.
Sub IspElseIf() If Marks >= 85 Then Debug.Print "Высший балл" ElseIf Marks >= 75 Then Debug.Print "Отлично" End If End Sub
Важно понимать, что порядок важен. Условие If проверяется
первым.
Если это правда, то печатается «Высший балл», и оператор If заканчивается.
Если оно ложно, то код переходит к следующему ElseIf и
проверяет его состояние.
Давайте поменяемся местами If и ElseIf из последнего
примера. Код теперь выглядит так
Sub IspElseIfNeverno() ' Этот код неверен, так как ElseIf никогда не будет верным If Marks >= 75 Then Debug.Print "Отлично" ElseIf Marks >= 85 Then ' код никогда не достигнет здесь Debug.Print "Высший балл" End If End Sub
В этом случае мы сначала проверяем значение более 75. Мы никогда не будем печатать «Высший балл», потому что, если значение больше 85, это вызовет первый оператор if.
Чтобы избежать подобных проблем, мы должны использовать два
условия. Они помогают точно указать, что вы ищете, чтобы избежать путаницы.
Пример ниже показывает, как их использовать. Мы рассмотрим более многочисленные
условия в разделе ниже.
If marks >= 75 And marks < 85 Then Debug.Print "Отлично" ElseIf marks >= 85 And marks <= 100 Then Debug.Print "Высший балл" End If
Давайте расширим оригинальный код. Вы можете использовать столько операторов ElseIf, сколько захотите. Мы добавим еще несколько, чтобы учесть все наши классификации баллов.
Использование If Else
Утверждение Else используется, как ловушка для всех. Это в основном означает «если бы не было условий» или «все остальное». В предыдущем примере кода мы не включили оператор печати для метки сбоя. Мы можем добавить это, используя Else.
Sub IspElse() If Marks >= 85 Then Debug.Print "Высший балл" ElseIf Marks >= 75 Then Debug.Print "Отлично" ElseIf Marks >= 55 Then Debug.Print "Хорошо" ElseIf Marks >= 40 Then Debug.Print "Удовлетворительно" Else ' Для всех других оценок Debug.Print "Незачет" End If End Sub
Так что, если это не один из других типов, то это провал.
Давайте напишем некоторый код с помощью наших примеров
данных и распечатаем студента и его классификацию.
Sub DobClass() ' получить последнюю строку Dim startRow As Long, lastRow As Long startRow = 2 lastRow = Sheet1.Cells(Sheet1.Rows.Count, 1).End(xlUp).Row Dim i As Long, Marks As Long Dim sClass As String ' Пройдите столбцы отметок For i = startRow To lastRow Marks = Sheet1.Range("C" & i).Value ' Проверьте отметки и классифицируйте соответственно If Marks >= 85 Then sClass = "Высший балл" ElseIf Marks >= 75 Then sClass = "Отлично" ElseIf Marks >= 55 Then sClass = "Хорошо" ElseIf Marks >= 40 Then sClass = "Удовлетворительно" Else ' Для всех других оценок sClass = "Незачет" End If ' Запишите класс в столбец E Sheet1.Range("E" & i).Value = sClass Next End Sub
Результаты выглядят так: в столбце E — классификация баллов
Используя If And/If Or
В выражении If может быть несколько условий. Ключевые слова VBA And и Or позволяют использовать несколько условий.
Эти слова работают так же, как вы используете их на
английском языке.
Давайте снова посмотрим на наши примеры данных. Теперь мы
хотим напечатать всех студентов, которые набрали от 50 до 80 баллов.
Мы используем Аnd, чтобы добавить дополнительное условие. Код гласит: если оценка больше или равна 50 и меньше 75, напечатайте имя студента.
Sub ProverkaStrokiOcenok() Dim i As Long, marks As Long For i = 2 To 11 ' Хранить оценки для текущего студента marks = Sheet1.Range("C" & i).Value ' Проверьте, если отметки больше 50 и меньше 75 If marks >= 50 And marks < 80 Then ' Напечатайте имя и фамилию в Immediate window (Ctrl+G) Debug.Print Sheet1.Range("A" & i).Value & Sheet1.Range("B" & i).Value End If Next End Sub
Вывести имя и фамилию в результаты:
- Дмитрий Маренин
- Олеся Клюева
- Евгений Яшин
В нашем следующем примере мы хотим знать, кто из студентов сдавал историю или геометрию. Таким образом, в данном случае мы говорим, изучал ли студент «История» ИЛИ изучал ли он «Геометрия» (Ctrl+G).
Sub ChitatObektOcenki() Dim i As Long, marks As Long ' Пройдите столбцы отметок For i = 2 To 11 marks = Sheet1.Range("D" & i).Value ' Проверьте, если отметки больше 50 и меньше 80 If marks = "История" Or marks = "Геометрия" Then ' Напечатайте имя и фамилию в Immediate window (Ctrl+G) Debug.Print Sheet1.Range("A" & i).Value & " " & Sheet1.Range("B" & i).Value End If Next End Sub
Результаты:
- Василий Кочин
- Александр Грохотов
- Дмитрий Маренин
- Николай Куликов
- Олеся Клюева
- Наталия Теплых
- Дмитрий Андреев
Использование нескольких таких условий часто является
источником ошибок. Эмпирическое правило, которое нужно помнить, должно быть
максимально простым.
Использование IF AND
And работает следующим образом:
Условие 1 | Условие 2 | Результат |
ИСТИНА | ИСТИНА | ИСТИНА |
ИСТИНА | ЛОЖЬ | ЛОЖЬ |
ЛОЖЬ | ИСТИНА | ЛОЖЬ |
ЛОЖЬ | ЛОЖЬ | ЛОЖЬ |
Что вы заметите, так это то, что And верно только тогда, когда все условия выполняются.
Использование IF OR
Ключевое слово OR работает следующим образом
Условие 1 | Условие 2 | Результат |
ИСТИНА | ИСТИНА | ИСТИНА |
ИСТИНА | ЛОЖЬ | ИСТИНА |
ЛОЖЬ | ИСТИНА | ИСТИНА |
ЛОЖЬ | ЛОЖЬ | ЛОЖЬ |
Что вы заметите, так это то, что OR ложно, только когда все условия ложны.
Смешивание And и Or может затруднить чтение кода и привести к ошибкам. Использование скобок может сделать условия более понятными.
Sub OrSAnd() Dim subject As String, marks As Long subject = "История" marks = 5 If (subject = "Геометрия" Or subject = "История") And marks >= 6 Then Debug.Print "ИСТИНА" Else Debug.Print "ЛОЖЬ" End If End Sub
Использование IF NOT
Также есть оператор NOT. Он возвращает противоположный результат условия.
Условие | Результат |
ИСТИНА | ЛОЖЬ |
ЛОЖЬ | ИСТИНА |
Следующие две строки кода эквивалентны.
If marks < 40 Then If Not marks >= 40 Then
так же, как и
If True Then If Not False Then
и
If False Then If Not True Then
Помещение условия в круглые скобки облегчает чтение кода
If Not (marks >= 40) Then
Распространенное использование Not — при проверке, был ли установлен объект. Возьмите Worksheet для примера. Здесь мы объявляем рабочий лист.
Dim mySheet As Worksheet ' Некоторый код здесь
Мы хотим проверить действительность mySheet перед его использованием. Мы можем проверить, если это Nothing.
If mySheet Is Nothing Then
Нет способа проверить, является ли это чем-то, поскольку есть много разных способов, которым это может быть что-то. Поэтому мы используем NOT с Nothing.
If Not mySheet Is Nothing Then
Если вы находите это немного запутанным, вы можете использовать круглые скобки, как здесь
If Not (mySheet Is Nothing) Then
Функция IIF
VBA имеет функцию, аналогичную функции Excel If. В Excel вы часто используете функцию If следующим образом:
= ЕСЛИ (F2 =»»,»», F1 / F2)
Формат
= If (условие, действие, если ИСТИНА, действие, если ЛОЖЬ).
VBA имеет функцию IIf, которая работает так же. Давайте посмотрим на примере. В следующем коде мы используем IIf для проверки значения переменной val. Если значение больше 10, мы печатаем ИСТИНА, в противном случае мы печатаем ЛОЖЬ.
Sub ProveritVal() Dim result As Boolean Dim val As Long ' Печатает ИСТИНА val = 11 result = IIf(val > 10, ИСТИНА, ЛОЖЬ) Debug.Print result ' печатает ЛОЖЬ val = 5 result = IIf(val > 10, ИСТИНА, ЛОЖЬ) Debug.Print result End Sub
В нашем следующем примере мы хотим распечатать «Удовлетворитеьно» или «Незачет» рядом с каждым студентом в зависимости от их баллов. В первом фрагменте кода мы будем использовать обычный оператор VBA If, чтобы сделать это.
Sub ProveritDiapazonOcenok() Dim i As Long, marks As Long For i = 2 To 11 ' Хранить оценки для текущего студента marks = Sheet1.Range("C" & i).Value ' Проверьте, прошел ли студент или нет If marks >= 40 Then ' Запишите имена для столбца F Sheet1.Range("E" & i) = "Удовлетворительно" Else Sheet1.Range("E" & i) = "Незачет" End If Next End Sub
В следующем фрагменте кода мы будем использовать функцию IIf. Код здесь намного аккуратнее.
Sub ProveritDiapazonOcenok () Dim i As Long, marks As Long For i = 2 To 11 ' Хранить оценки для текущего студента marks = Sheet1.Range("C" & i) ' Проверьте, прошел ли студент или нет Sheet1.Range("E" & i).Value = IIf(marks >= 40,"Удовлетворительно","Незачет") Next End Sub
Функция IIf очень полезна для простых случаев, когда вы имеете дело с двумя возможными вариантами.
Использование Nested IIf
Вы также можете вкладывать IIf-операторы, как в Excel. Это означает использование результата одного IIf с другим. Давайте добавим еще один тип результата в наши предыдущие примеры. Теперь мы хотим напечатать «Отлично», «Удовлетворительно» или «Незачетт» для каждого студента.
Используя обычный VBA, мы сделали бы это так
Sub ProveritRezultatiTip2() Dim i As Long, marks As Long For i = 2 To 11 ' Хранить оценки для текущего студента marks = Sheet1.Range("C" & i).Value If marks >= 75 Then Sheet1.Range("E" & i).Value = "Отлично" ElseIf marks >= 40 Then ' Запишите имена для столбца F Sheet1.Range("E" & i).Value = "Удовлетворительно" Else Sheet1.Range("E" & i).Value = "Незачет" End If Next End Sub
Используя вложенные IIfs, мы могли бы сделать это так
Sub IspNestedIIF() Dim i As Long, marks As Long, result As String For i = 2 To 11 marks = Sheet1.Range("C" & i).Value result = IIf(marks >= 55,"Хорошо",IIf(marks >= 40,"Удовлетворительно","Незачет")) Sheet1.Range("E" & i).Value = result Next End Sub
Использование вложенного IIf хорошо в простых случаях, подобных этому. Код прост для чтения и, следовательно, вряд ли вызовет ошибки.
Чего нужно остерегаться
Важно понимать, что функция IIf всегда оценивает как
Истинную, так и Ложную части выражения независимо от условия.
В следующем примере мы хотим разделить по баллам, когда он не равен нулю. Если он равен нулю, мы хотим вернуть ноль.
marks = 0 total = IIf(marks = 0, 0, 60 / marks)
Однако, когда отметки равны нулю, код выдаст ошибку «Делить на ноль». Это потому, что он оценивает как Истинные, так и Ложные утверждения. Здесь ложное утверждение, т.е. (60 / Marks), оценивается как ошибка, потому что отметки равны нулю.
Если мы используем нормальный оператор IF, он будет
запускать только соответствующую строку.
marks = 0 If marks = 0 Then 'Выполняет эту строку только когда отметки равны нулю total = 0 Else 'Выполняет только эту строку, когда отметки не равны нулю total = 60 / marks End If
Это также означает, что если у вас есть функции для ИСТИНА и ЛОЖЬ, то обе будут выполнены. Таким образом, IIF будет запускать обе функции, даже если он использует только одно возвращаемое значение. Например:
' Обе функции будут выполняться каждый раз total = IIf(marks = 0, Func1, Func2)
IF против IIf
Так что лучше?
В этом случае вы можете видеть, что IIf короче для написания и аккуратнее. Однако если условия усложняются, вам лучше использовать обычное выражение If. Недостатком IIf является то, что он недостаточно известен, поэтому другие пользователи могут не понимать его так же, как и код, написанный с помощью обычного оператора if.
Кроме того, как мы обсуждали в последнем разделе, IIF всегда оценивает части ИСТИНА и ЛОЖЬ, поэтому, если вы имеете дело с большим количеством данных, оператор IF будет быстрее.
Мое эмпирическое правило заключается в том, чтобы
использовать IIf, когда
он будет прост для чтения и не требует вызовов функций. Для более сложных
случаев используйте обычный оператор If.
Использование Select Case
Оператор Select Case
— это альтернативный способ написания статистики If с большим количеством ElseIf. Этот тип операторов
вы найдете в большинстве популярных языков программирования, где он называется
оператором Switch. Например,
Java, C #, C ++ и Javascript
имеют оператор switch.
Формат
Select Case [переменная] Case [условие 1] Case [условие 2] Case [условие n] Case Else End Select
Давайте возьмем наш пример DobClass сверху и перепишем его с помощью оператора Select Case.
Sub DobavitClass() ' получить последнюю строку Dim startRow As Long, lastRow As Long startRow = 2 lastRow = Sheet1.Cells(Sheet1.Rows.Count, 1).End(xlUp).Row Dim i As Long, Marks As Long Dim sClass As String ' Пройдите столбцы отметок For i = startRow To lastRow Marks = Sheet1.Range("C" & i).Value ' Проверьте отметки и классифицируйте соответственно If Marks >= 85 Then sClass = "Высший балл" ElseIf Marks >= 75 Then sClass = "Отлично" ElseIf Marks >= 55 Then sClass = "Хорошо" ElseIf Marks >= 40 Then sClass = "Удовлетворительно" Else ' Для всех других оценок sClass = "Незачет" End If ' Запишите класс в столбец E Sheet1.Range("E" & i).Value = sClass Next End Sub
Ниже приведен тот же код с использованием оператора Select Case. Главное, что вы заметите, это то, что мы используем “Case 85 to 100” rather than “marks >=85 And marks <=100”. , а не “marks >=85 And marks <=100”.
Sub DobavitClassSSelect() ' получить первую и последнюю строки Dim firstRow As Long, lastRow As Long firstRow = 2 lastRow = Cells(Cells.Rows.Count, 1).End(xlUp).Row Dim i As Long, marks As Long Dim sClass As String ' Пройдите столбцы отметок For i = firstRow To lastRow marks = Sheet1.Range("C" & i).Value ' Проверьте отметки и классифицируйте соответственно Select Case marks Case 85 To 100 sClass = "Высший балл" Case 75 To 84 sClass = "Отлично" Case 55 To 74 sClass = "Хорошо" Case 40 To 54 sClass = "Удовлетворительно" Case Else ' Для всех других оценок sClass = "Незачет" End Select ' Запишите класс в столбец E Sheet1.Range("E" & i).Value = sClass Next End Sub
Использование Case Is
Вы можете переписать оператор select в том же формате, что и оригинальный ElseIf. Вы можете использовать Is с Case.
Select Case marks Case Is >= 85 sClass = "Высший балл" Case Is >= 75 sClass = "Отлично" Case Is >= 55 sClass = "Хорошо" Case Is >= 40 sClass = "Удовлетворительно" Case Else ' Для всех других оценок sClass = "Незачет" End Select
Вы можете использовать Is для проверки нескольких значений.
В следующем коде мы проверяем, равны ли оценки 5, 7 или 9.
Sub TestNeskZnach() Dim marks As Long marks = 7 Select Case marks Case Is = 5, 7, 9 Debug.Print True Case Else Debug.Print False End Select End Sub
Попробуйте это упражнение
В этой статье много рассказывали о выражении If. Хороший способ помочь вам понять — это попытаться написать код, используя темы, которые мы рассмотрели. В следующем упражнении используются тестовые данные из этой статьи. Ответ на упражнение ниже.
Мы будем использовать ячейку G1, чтобы написать имя
субъекта.
В колонках от H до L запишите всех студентов, которые имеют оценки по этому предмету. Мы хотим классифицировать их результат как успешный или неудачный. Оценка ниже 40 — неудача, оценка 40 или выше — Зачет.
Колонка H: Имя
Колонка I: Фамилия
Колонка J: Баллы
Колонка H: Предмет
Столбец I: Тип результата — Зачет или Незачет
Если ячейка G1 содержит «Геометрия», то ваш результат должен выглядеть следующим образом:
Ответ на упражнение
Следующий код показывает, как выполнить вышеупомянутое упражнение.
Примечание: есть много способов выполнить задачу, поэтому не расстраивайтесь, если ваш код отличается.
Sub ZapisatRezultat() ' Получить тему Dim subject As String subject = Sheet1.Range("G1").Value If subject = "" Then Exit Sub End If ' Получить первый и последний ряд Dim firstRow As Long, lastRow As Long firstRow = 2 lastRow = Cells(Cells.Rows.Count, 1).End(xlUp).Row ' Очистить любой существующий вывод Sheet1.Range("H:L").ClearContents ' Отслеживать выходной ряд Dim outRow As Long outRow = 1 Dim i As Long, marks As Long, rowSubject As String ' Прочитать данные For i = firstRow To lastRow marks = Sheet1.Range("C" & i).Value rowSubject = Sheet1.Range("D" & i).Value If rowSubject = subject Then ' Запишите данные студента, если предмет Геометрия Sheet1.Range("A" & i & ":" & "D" & i).Copy Sheet1.Range("H" & outRow).PasteSpecial xlPasteValues ' Запишите Зачет или Незачет If marks < 40 Then Sheet1.Range("L" & outRow).Value = "Незачет" ElseIf marks >= 40 Then Sheet1.Range("L" & outRow).Value = "Зачет" End If ' Переместить вывод в следующую строку outRow = outRow + 1 End If Next i End Sub
