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:

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:

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

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.

This post provides a complete guide to the VBA If Statement in VBA. If you are looking for the syntax then check out the quick guide in the first section which includes some examples.

Quick Guide to the VBA If Statement

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

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

Play around with this example and check the value or the > sign and see how the results change.

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

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

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

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

    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

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

What you will notice is that AND is only true when all conditions are true

Using If Or

The OR keyword works as follows

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.

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.

' https://excelmacromastery.com/
Sub TestMultiValues()
    
    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

Краткое руководство по VBA If Statement

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:

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.

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:

Что вы заметите, так это то, что And верно только тогда, когда все условия выполняются.

Использование IF OR

Ключевое слово OR работает следующим образом

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.

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

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:

1. Go to the Developer tab.
2. Click on Visual Basic option. This will open the VB editor in the backend.
3. 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.
4. Go to Insert and click on Module. This will insert a module object for your workbook.
5. Copy and paste the code in the module window.

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

Logic Gates

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:

How to Use IF OR Statements in VBA

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:

With Select Case, it is this syntax:

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.
