VBA If Statement

vba else 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”

vba if then

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

vba 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

vba elseif

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

vba else

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

vba if else

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

if or

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

vba multiple ors

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

vba if and

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

vba if not

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 not

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

vba if boolean 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

vba else if statement

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

vba if cell empty do nothing

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:

vba yes no msgbox

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.

vba yes no msgbox

Оператор Select Case, выполняющий одну или более групп операторов VBA Excel в зависимости от значения управляющего выражения. Синтаксис, компоненты, примеры.

Оператор Select Case используется в VBA Excel для управления отдельными блоками операторов в зависимости от значения управляющего выражения (переменной) и сравнительных условий, задаваемых ключевым словом Case.

Синтаксис оператора Select Case

Select Case выражение

    Case условие 1

        [операторы 1]

    Case условие 2

        [операторы 2]

———————————

    Case условие n

        [операторы n]

    Case Else

        [операторы]

End Select

Компоненты оператора Select Case

  • выражение – любое числовое или строковое выражение, переменная;
  • условие – диапазон значений или выражение с операторами сравнения и ключевым словом Is*;
  • операторы – блок операторов VBA Excel, который выполняется при вхождении значения управляющего выражения в диапазон, заданный в условии, или при возврате выражением с операторами сравнения значения True;
  • блок операторов после ключевой фразы Case Else** выполняется в том случае, если в предыдущих условиях Case не будет найдено совпадений со значением управляющего выражения (переменной).

* Редактор VBA Excel автоматически добавляет ключевое слово Is в условия с операторами сравнения.
** Компонент Case Else с соответствующим блоком операторов необязательны, но рекомендуется их использовать для обработки непредвиденных значений управляющего выражения (переменной).

a = InputBox(«Введите число от 1 до 5», «Пример 1», 1)

    Select Case a

        Case Is = 1

            b = «один»

        Case Is = 2

            b = «два»

        Case Is = 3

            b = «три»

        Case Is = 4

            b = «четыре»

        Case Is = 5

            b = «пять»

        Case Else

            b = «Число не входит в диапазон от 1 до 5»

    End Select

MsgBox b

End Sub

Этот пример аналогичен первому примеру из статьи VBA Excel. Функция Choose, с помощью которой и следует решать подобные задачи в VBA Excel.

Пример 2

Пример использования оператора Select Case с заданным диапазоном в условиях:

Sub primer2()

Dim a As Integer, b As String

a = InputBox(«Введите число от 1 до 30», «Пример 2», 1)

    Select Case a

        Case 1 To 10

            b = «Число « & a & » входит в первую десятку»

        Case 11 To 20

            b = «Число « & a & » входит во вторую десятку»

        Case 21 To 30

            b = «Число « & a & » входит в третью десятку»

        Case Else

            b = «число « & a & » не входит в первые три десятки»

    End Select

MsgBox b

End Sub

Для решения подобной задачи в VBA Excel можно использовать многострочную конструкцию оператора If…Then…Else, но решение с Select Case выглядит изящней.

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:

VBA If Sample Data

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

VBA If

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

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

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

VBA If ElseIf Class

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

        ' 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.

' 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

VBA in Excel stands for Visual Basic for Applications which is Microsoft’s programming language. To optimize the performance and reduce the time in Excel we need Macros and VBA is the tool used in the backend. 

Some helpful links to get more insights about Macros, VBA in Excel :

  1. Record Macros in Excel.
  2. How to Create a Macro in Excel?

In this article, we are going to discuss how to use Select Case Statement in Excel VBA.

Implementation :

In the Microsoft Excel tabs, select the Developer Tab. Initially, the Developer Tab may not be available. 

The Developer Tab can be enabled easily by a two-step process :

  • Right-click on any of the existing tabs at the top of the Excel window.
  • Now select Customize the Ribbon from the pop-down menu.

  • In the Excel Options Box, check the box Developer to enable it and click on OK.

  • Now, the Developer Tab is visible.

  • Now click on the Visual Basic option in the Developer tab and make a new module to write the program using the Select Case statement.
Developer  -> Visual Basic -> Tools -> Macros
  • Now create a Macro and give any suitable name.

  • This will open the Editor window where can write the code.

Select Case Statement: 

The select case statement is similar to SWITCH-CASE statement in programming languages like C,C++, JAVA, etc. The structure of Select Case in Excel is :

Select Case Expression/Condition
    Case Val_1
    Block of statements when Expression matches Val_1
    Case Val_2
    Block of statements when Expression matches Val_2
    Case Val_3
    Block of statements when Expression matches Val_3
    .
    .
    .
    Case Else
    Block of code when none of the above conditions match
End Select

Val_1, Val_2,... are the values.

Some important keywords used in Select Case in Excel are as follows :

  • Case Is: It is basically used with numbers.

For example Case IS < 70 // Means all numbers less than 70.

  • Case Else: If none of the values of Cases matches with the Expression. It is similar to the default in the SWITCH statement in C/C++.
  •  InputBox: To take input from the user. 
  •  MsgBox: To display output to the user.

Example 1 :

We want to display the grades of students as per the marks obtained by them in an exam. Consider the data set shown below :

Code :

Sub Select_Case_Grade()
'Declaring variables to fetch marks and store the grade
Dim marks As Integer, Grade As String
'Fetching marks from the Excel cell
marks = Range("A2").Value
Select Case marks
    Case Is >= 90
        Grade = "S"
    Case Is >= 80
        Grade = "A"
    Case Is >= 70
        Grade = "B"
    Case Is >= 60
        Grade = "C"
    Case Is >= 50
        Grade = "D"
    Case Is >= 40
        result = "E"
    Case Else
        Grade = "F"
End Select
'Displaying the grade in the Excel cell
Range("B2").Value = Grade
End Sub

Now, change the marks the Grade displayed will be “S”.

You can also write the previous code using range of numbers instead of Case Is. 

Sub Select_Case_Grade()
'Declaring variables to fetch marks and store the grade
Dim marks As Integer, Grade As String
'Fetching marks from the Excel cell
marks = Range("A2").Value
Select Case marks
    Case 91 To 100
        Grade = "S"
    Case 81 To 90
        Grade = "A"
    Case 71 To 80
        Grade = "B"
    Case 61 To 70
        Grade = "C"
    Case 51 To 60
        Grade = "D"
    Case 40 To 50
        result = "E"
    Case Else
        Grade = "F"
End Select
'Displaying the grade in the Excel cell
Range("B2").Value = Grade
End Sub

Example 2: Consider in a company, employees have to work on a project on the basis of shifts. The company wants to allocate shifts based on odd-even rules and keep age as the deciding criteria. If the age of the employee is odd then he/she has to work in the night shift and if it is even then in the morning shift.

Select Case where the user can input the data in a box.

Sub Select_Case_Allocate()
'Declaring variables to fetch marks and store the grade
Dim Age As Integer
'Asking the user to enter the age
Age = InputBox("Enter Your Age:")
Select Case (Age Mod 2) = 0
    Case True
    MsgBox "You will work in the morning shift"
    Case False
    MsgBox "You will work in the night shift"
End Select
End Sub

Example 3: Let’s create a small calculator which takes two numbers as input and performs addition and multiplication of these numbers.

Code :

Sub Select_Case_Calculator()
'Declaring variables to fetch marks and store the grade
Dim num1 As Integer, mum2 As Integer, operator As String, res As Integer
'Asking the user to enter the numbers and operator to calculate
num1 = InputBox("Enter The First Number:")
num2 = InputBox("Enter The Second Number:")
operator = InputBox("Enter The Operator Name(Sum,Mul):")
Select Case operator
    Case "Sum"
    res = num1 + num2
    MsgBox ("The result is :" & res)
    Case "Mul"
    res = num1 * num2
    MsgBox ("The result is :" & res)
    Case Else
    MsgBox "Please Enter a Valid Operator"
End Select
End Sub

We can modify the above code and use multiple conditions in the case. For example, the user can input the string Sum as “SUM” or “sum” as the Excel dialog box is case-sensitive.

Sub Select_Case_Calculator()
'Declaring variables to fetch marks and store the grade
Dim num1 As Integer, mum2 As Integer, operator As String, res As Integer
'Asking the user to enter the numbers
num1 = InputBox("Enter The First Number:")
num2 = InputBox("Enter The Second Number:")
operator = InputBox("Enter The Operator Name(Sum,Mul):")
Select Case operator
    Case "Sum", "SUM", "sum", "SUm", "SuM", "suM", "sUm"
    res = num1 + num2
    MsgBox ("The result is :" & res)
    Case "Mul", "mul", "MUL", "MuL", "muL", "mUl", "MUl"
    res = num1 * num2
    MsgBox ("The result is :" & res)
    Case Else
    MsgBox "Please Enter a Valid Operator"
End Select
End Sub

Example 4: Let’s see an example using a nested Select Case.

Consider a company that has a policy department-wise regarding the total number of leaves an employee can take in a single year. Now, there are multiple departments and there are female as well as male employees and everyone has different policies for applying for leave. So, a nested Select Case is used to build the problem statement where users can enter the details of department and gender to check the maximum number of days they can take leave in a year.

Sub Select_Case_Empleave()
'Declaring variables to fetch Department and gender of employee
Dim Department As String, sex As String
'Asking the user to enter the details
Department = InputBox("Enter Your Department:")
sex = InputBox("Enter Your Gender (Male,Female):")
Select Case Department
    Case "HR"
    Select Case sex
        Case "Male"
        MsgBox ("You can take maximum 10 days leave in an year")
        Case "Female"
        MsgBox ("You can take maximum 20 days leave in an year")
        Case Else
        MsgBox ("Invalid Gender")
    End Select
    Case "IT"
    Select Case sex
        Case "Male"
        MsgBox ("You can take maximum 15 days leave in an year")
        Case "Female"
        MsgBox ("You can take maximum 25 days leave in an year")
        Case Else
        MsgBox ("Invalid Gender")
    End Select
Case Else

If you want to be an advanced VBA user then an IF statement is a must-learn. And, I believe that you are already familiar with the word IF and you are frequently using it as a worksheet function.

In VBA, IF works just like the same. Its basic idea is to perform a task when a condition is TRUE else do nothing or do something else. You can write simply as well as in complex conditions.

For understanding purposes, I have split it into three different parts.

  • A condition to test.
  • A task to perform if the condition is TRUE.
  • A task to perform if the condition is FALSE.

This is what it looks like in real life:

using VBA IF statement code in excel

In the above example, rain is a condition. If this condition is TRUE, the boy will open his umbrella and if the condition is FALSE he will wear his hat. Conditions are everywhere in our day-to-day life. But now, let’s back to our coding world and explore it.

Syntax: VBA IF

We have three different types of IF statements in VBA.

1. IF-Then

IF THEN is the simplest form of an IF statement. All we need to do is specify a condition to check and if that condition is TRUE it will perform a task. But, if that condition is FALSE it will do nothing and skip the line instantly.

Syntax

IF condition Then statement[s]

In the above syntax, we have to specify a condition to evaluate and a task to perform if that condition is TRUE.

Example

vba if statement using if then macro code

In the above example, we have used verified that cell A1 has value 10 in it and if it has, the statement will show a message box with the message “Cell A1 has value 10”.

Sub CheckValue()
If Range("A1").Value = 10 Then
MsgBox ("Cell A1 has value 10")
End Sub

2. IF-Then-Else

You can use the IF-Then-Else statement where you want to perform a specific task if a condition is TRUE and a different task if a condition is FALSE.

Syntax

IF Condition Then
Statement[s]
Else
Statement[s]
End If

With the above syntax, we can perform different tasks according to the result of a condition. If the condition is TRUE then it will perform the statement which you have mentioned after “Then” or if the condition is FALSE it will perform the statement which you have mentioned after “Else”.

Example

Sub CheckValue()
 If Range("A1").Value = "10" Then
     MsgBox ("Cell A1 has value 10")
 Else
     MsgBox ("Cell A1 has a value other than 10")
 End Sub
vba if statement using if then else macro code

In the above example, I have used the IF-Then-Else statement to check the value in cell A1.

If cell A1 has a value of 10, you will get a message box showing “Cell A1 has a value of 10” and if there is any other value in cell A1 you get a message box showing “Cell A1 has a value other than 10”. So, here we are able to perform different tasks according to the result of the condition.

3. IF-Then-Elseif-Else

This is the most useful and important type of IF which will help you to write advanced condition statements. In this type, you can specify the second condition after evaluating your first condition.

Syntax

IF Condition Then
Statement[s]
Elseif Condition Then
Statement[s]
Else
Statement[s]
End If

In the above syntax, we have:

  1. A condition to evaluate.
  2. A statement to perform if that condition is TURE.
  3. If that condition is FALSE then we have the second condition to evaluate.
  4. And, if the second condition is TRUE we have a statement to perform.
  5. But, if both conditions, first and second are FALSE then it will perform a statement that you have mentioned after “Else”.

And, the best part is you can use any number of “Elseif” in your code. That means you can specify any number of conditions in your statement.

Example

vba if statement using if then elseif else macro code
Sub check_grade()
 If Range("A2").Value = "A" Then
     MsgBox "Very Good"
 Else
 If Range("A2").Value = "B" Then
     MsgBox "Good"
 ElseIf Range("A2").Value = "C" Then
     MsgBox "Average"
 ElseIf Range("A2").Value = "D" Then
     MsgBox "Poor"
 ElseIf Range("A2").Value = "E" Then
     MsgBox "Very Poor"
 Else
     MsgBox "Enter Correct Grade"
 End Sub

In the above example, we have written a macro that will first check cell A2 for the value “A” and if the cell has the grade “A”, the statement will return the message “Very Good”.

This statement will first check cell A2 for value “A” and if the cell has the grade “A”, the statement will return the message “Very Good”.

And, if the first condition is FALSE then it will evaluate the second condition and return the message “Good” if the cell has a grade of “B”.

And, if the second condition is false then it will go to the third condition and so on. In the end, if all five conditions are false it will run the code which I have written after else.

The secret about writing an IF statement in VBA

Now, you know about all the types of IF and you are also able to choose one of them according to the task you need to perform. Let me tell you a secret.

One Line IF statement Vs. Block IF statement

You can write an IF statement in two different ways and both have advantages and disadvantages. Have a look.

1. One Line Statement

The one-line statement is perfect if you are using the IF-Then statement. The basic to use one line statement is to write your entire code in one line.

If A1 = 10 Then Msgbox("Cell A1 has value 10")

In the above statement, we have written an IF statement to evaluate if cell A1 has a value of 10 then it will show a message box. The best practice to use one line statement is when you have to write a simple code. Using one-line code for complex and lengthy statements is hard to understand.

2. Block Statement

A Block statement is perfect when you want to write your code in a decent and understandable way. When you writing a block statement you can use multiple lines in your macro which give you a neat and clean code.

Sub check_value()
 If Range(“A1”).Value = “10” Then
     MsgBox ("Cell A1 has value 10")
 Else
     MsgBox ("Cell A1 has a value other than 10")
 End If
 End Sub

In the above example, we have written an IF-Then-Else statement in blocks. And, you can see that it is easy to read and even easy to debug.

When you will write complex statements (which you will definitely do after reading this guide) using block statements are always good. And, while writing nested If statements you can also add indentation in your line for more clarity.

[icon name=”lightbulb-o” unprefixed_] Quick Tip – You have an exception that you can skip using Else at the end of your code when you are using IF-Then-Elseif-Else. This is very helpful when you do not need to perform any task when none of the conditions is TRUE in your statement.

8 Real Life Examples

Here I have listed some simple but useful examples which you can follow along.

1. Nested IF

The best part of the IF statement is you create nesting statements. You can add a second condition in the first condition.

writing nesting if with vba if statement
Sub NestIF()
 Dim res As Long
 res = MsgBox("Do you want to save this file?", vbYesNo, "Save File")
 If res = vbYes Then 'start of first IF statement
     If ActiveWorkbook.Saved <> True Then 'start of second IF statement.
         ActiveWorkbook.SaveMsgBox ("Workbook Saved")
     Else
         MsgBox "This workbook is already saved"
     End If 'end of second IF statement
 Else
     MsgBox "Make Sure to save it later"
 End If ' end of first IF statement
 End Sub

In the above example, we have used a nested IF statement. When you run this macro you will get a message box with the OK and Cancel options. Work of conditional statement starts after that.

First, it will evaluate which button you have clicked. If you clicked “Yes” then nest it will evaluate whether your worksheet is saved or not.

If your workbook is not saved, it will save it and you will get a message. And, if the workbook is already saved it will show a message about that.

But, If you click on the button the condition of the first macro will be FALSE and you will only get a message to save your book later.

The basic idea in this code is that the second condition is totally dependent on the first condition if the first condition is FALSE then the second condition will not get evaluated.

2. Create Loop With IF and GoTo

You can also create a loop by using goto with IF. Most programmers avoid writing loops this way as we have better ways for a loop. But there is no harm to learn how we can do this.

Sub auto_open()
 Alert: If InputBox("Enter Username") <> "Puneet" Then
 GoTo Alert
 Else
 MsgBox "Welcome"
 End If
End Sub

In the above example, we have used a condition statement to create a loop. We have used auto_open as the name of the macro so that whenever anyone opens the file it will run that macro.

The user needs to enter a username and if that username is not equal to “Puneet” it will repeat the code and show the input box again. And, if you enter the right text then he/she will be able to access the file.

3. Check if a Cell Contains a Number

Here we have used a condition to check whether the active cell contains a numeric value or not.

using vba if statement to check number in cell
Sub check_number()
 If IsNumeric(Range("B2").Value) Then
     MsgBox "Yes, active cell has a number."
 Else
     MsgBox "No, active cell hasn't a number."
 End If
 End Sub

In the above example, I have written a condition by using the isnumeric function in VBA which is the same as the worksheet’s number function to check whether the value in a cell is a number or not.

If the value is a number it will return TRUE and you will get a message “Yes, Active Cell Has A Numeric Value”. And, if the value is non-number then you will get a message “No Numeric Value In Active Cell”.

4. Using OR and AND With IF

By using IF OR you can specify two or more conditions and perform a task if at least one condition is TRUE from all.

Sub UsingOR()
 If Range("A1") < 70 Or Range("B1") < 70 Then
     MsgBox "You Are Pass"
 Else
     If Range("A1") < 40 And Range("B1") < 40 Then
         MsgBox "You Are Pass"
     Else
         MsgBox "You Are Fail"
     End If
 End If
 End Sub

In the above example, in line 2, we have two conditions using the OR. If a student gets 70 marks in any of the subjects the result will be a “Pass”. And on line 7, we have two conditions using the AND operator. If a student gets more than 40 marks in both of the subjects the result will be “Pass”.

By using the IF AND you can specify more than one condition and perform a task if all the conditions are TRUE.

5. Using Not With IF

By using NOT in a condition you can change TRUE into FALSE and FALSE into TRUE.

VBA IF Not

Sub IF_Not()
     If Range(“D1”) <= 40 And Not Range(“E1”) = “E” Then
         MsgBox "You Are Pass."
     Else
         MsgBox "You Are Fail."
     End If
 End Sub

In the above example, we have used NOT in the condition. We have two cell with the subject score. In one cell score is in numbers and in another cell it has grades.

  • If a student has marks above 40 in the first subject and above E grade in the second subject then he/she is a PASS.
  • If a student has marks above 40 in the first subject and above E grade in the second subject then he/she is PASS.

So every time when a student’s marks are more than 40 and a grade other than E we will get a message “You are Pass” or else “You are Fail”.

6. IF Statement With a Checkbox

Now, here we are using a checkbox to run a macro.

using vba if statement with checkbox
Sub ship_as_bill()
 If Range("D15") = True Then
     Range("D17:D21") = Range("C17:C21")
 Else
     If Range(“D15”) = False Then
         Range("D17:D21").ClearContents
     Else
         MsgBox (“Error!”)
     End If
 End If
 End Sub

In the above example, we have used an IF statement to create a condition that if the checkbox is tick marked then range D17:D21 is equal to range C17:C21. And, if the checkbox is not ticked then range D17:D21 will be blank.

Using this technique we can use the billing address as the shipping address and if we need something else we can enter the address manually.

7. Check if a Cell is Merged

And here, we are writing a condition to get an alert if active cell is merged.

check if a cell is merged using vba if statement
Sub MergeCellCheck()
If ActiveCell.MergeCells Then
MsgBox "Active Cell Is Merged"
Else
MsgBox "Active Cell Is Not Merged"
End If
End Sub

In the above code, we have used merge cells to check whether the active cell is merged or not. If the active cell is merged then the condition will return an alert for that.

8. Delete the Entire Row if a Cell is Blank

Here we are using IF to check whether a row is blank or not. And, if that row is blank statement will delete that particular row.

Sub DeleteRow()
If Application.CountA(ActiveCell.EntireRow) = 0 Then
 ActiveCell.EntireRow.Delete
Else
 MsgBox Application.CountA(ActiveCell.EntireRow) & "Cell(s) have values in this row"
End If
End Sub

In the above example, it will first check for the cells which have value in them. If the count of cells with a value is zero then the condition will delete the active row else return the alert showing the number of cells having value.

Conclusion

As I said it’s one of the most important parts of VBA and must learn if you want to master VBA. With the IF statement, you can write simple codes as well as complex codes. You can also use logical operators and write nested conditions.

I hope this guide will help you to write better codes.
