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).
Примеры использования в VBA Excel
Пример 1
Пример использования оператора Select Case с операторами сравнения в условиях:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
Sub primer1() Dim a As Integer, b As String 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.
The Select Case statement is an alternative way to write If/ElseIf statements.
You will find a Select Case statement equivalent in most popular programming languages. In many languages, the equivalent statement is the Switch statement. For example, the languages Java, C#, C++ and Javascript all have a switch statement.
Case Statement Quick Guide
Case Options | Description | Examples |
---|---|---|
Is | Use with operators =, >,<,<>,>=,<= | Case Is = 5 Case Is = «Apple» Case Is > 5 Case Is <= 10 |
To | Use for a range of numbers | Case 5 To 10 Case 85 To 99 Case «A» To «D» |
Comma | Use the comma to include multiple conditions for one case | Case 1, 3, 9, 11 Case 1, Is > 20, 10 To 15 |
No operator | The same as «Is =» | Case 5 Case «Apple» |
Select Case Format
The format of the VBA Select Case statement is a follows:
Select Case [variable] Case [condition 1] [Statement 1] Case [condition 2] [Statement 2] Case [condition n] [Statement n] Case Else [Statement else] End Select
The following is a simple example of using the Select Case Statement:
' https://excelmacromastery.com/ Public Sub Select_Case_Example() ' Read value from cell A1 on sheet1 Dim airportCode As String airportCode = Sheet1.Range("A1").Value ' Print the name of the airport to the Immediate Window(Ctrl + G) Select Case airportCode Case "LHR" Debug.Print "London Heathrow" Case "JFK" Debug.Print "John F Kennedy" Case "SIN" Debug.Print "Singapore" End Select End Sub
The code below is the equivalent If statement:
' https://excelmacromastery.com/ Public Sub If_Example() ' Read value from cell A1 on sheet1 Dim airportCode As String airportCode = Sheet1.Range("A1").Value ' Print the name of the airport to the Immediate Window(Ctrl + G) If airportCode = "LHR" Then Debug.Print "London Heathrow" ElseIf airportCode = "JFK" Then Debug.Print "John F Kennedy" ElseIf airportCode = "SIN" Then Debug.Print "Singapore" End If End Sub
We use the Select Case statement because it provides us with more flexibility than an If statement. We will see more above this below.
Using the Colon Operator
We can use the colon symbol “:” to make our Case statements look neater. The colon symbol allows us to place two lines VBA lines of code on one line. They are still treated as two lines by VBA but the code looks neater:
Select Case airportCode Case "LHR": Debug.Print "London Heathrow" Case "JFK": Debug.Print "John F Kennedy" Case "SIN": Debug.Print "Singapore" End Select
Code Between Case Statements
In the previous examples we had just one line of code for each Case Condition. You can have as many lines of code as you want. However it is good practice to keep it to one line if possible. The purpose of the Select Case statement is to make the code readable.
In the following example, we have multiple lines of code for the Case “London”:
' https://excelmacromastery.com/ Sub MultiLine() Dim city As String city = Sheet1.Range("A1").Value Select Case city Case "London" ' would be better in another sub Count = Count + 1 x = 6 a = 5 Case Else Debug.Print "other city" End Select End Sub
If we have multiple lines, we could place them in a sub and then call this sub:
Select Case city Case "London" Call UpdateValues Case Else Debug.Print "other city" End Select
Case Else
The Case Else statement is used with Select Case. It is the equivalent of the Else statement used with If. In simple terms, it means “if no other options were selected then select this one”.
Case Else is often used to check that a valid value was supplied. In the example below, it is used to check if the Airport Code was valid:
' https://excelmacromastery.com/ Public Sub Select_Case_Else() ' Read value from cell A1 on sheet1 Dim airportCode As String airportCode = Sheet1.Range("A1").Value ' Print the name of the airport to the Immediate Window (Ctrl + G) Select Case airportCode Case "LHR" Debug.Print "London Heathrow" Case "JFK" Debug.Print "John F Kennedy" Case "SIN" Debug.Print "Singapore" Case Else MsgBox "The airport code is not valid.", vbInformation End Select End Sub
Using Select Case with Numbers
We can use the To keyword to specify a range of numbers:
' https://excelmacromastery.com/ Select Case marks Case 85 To 100 Debug.Print "High Distinction" Case 75 To 84 Debug.Print "Distinction" Case 55 To 74 Debug.Print "Credit" Case 40 To 54 Debug.Print "Pass" Case Else Debug.Print "Fail" End Select
Select Case Is
We can use the Is keyword if we want to use the operators like =, >,< etc.
In the below example, I have rewritten the previous Select Case statement using Is instead of To:
' https://excelmacromastery.com/ Select Case marks Case Is >= 85 Debug.Print "High Distinction" Case Is >= 75 Debug.Print "Distinction" Case Is >= 55 Debug.Print "Credit" Case Is >= 40 Debug.Print "Pass" Case Else ' For all other marks Debug.Print "Fail" End Select
We don’t need to use the Is keyword when using equals. The two lines below are equivalent:
Case "LHR" Case Is = "LHR"
So are these two:
Case 10 Case Is = 10
Select Case Multiple Values
We can have multiple case conditions on one line. We simply use the comma to separate them:
Case Is > 85, 70 To 75, 83
Case 2, 4, 6, 8 Debug.Print "Even numbers" Case 1, 3, 5, 7 Debug.Print "Odd numbers"
The following is an example of using multiple strings:
' https://excelmacromastery.com/ Public Sub Select_Case_Multi() Dim city As String ' Change value to test city = "Dublin" ' Print the name of the airport based on the code Select Case city Case "Paris", "London", "Dublin" Debug.Print "Europe" Case "Singapore", "Hanoi" Debug.Print "Asia" Case Else MsgBox "The city is not valid.", vbInformation End Select End Sub
Comparing Upper and Lower Case
We can use Option Compare at the top of the VBA module. This affects how strings are compared within that module.
We can use Binary or Text with Option Compare.
Option Compare Binary
Option Compare Text
- Binary means that VBA checks the case of the letters – case sensitive.
- Text means that VBA ignores the case of the letters – not case sensitive.
If we set “Option Compare Binary” then the following If and Case statements will evaluate to false.
If we set “Option Compare Text” they will evaluate to true:
city = "Dublin" ' true for "Option Compare Text" ' false for "Option Compare binary" If city = "DUBLIN" Then End If Select Case city ' true for "Option Compare Text" ' false for "Option Compare binary" Case "DUBLIN" End Select
You can try the following example. Change between Binary and Text and check the results:
' Change between "Binary" and "Text" and compare results ' https://excelmacromastery.com/ Option Compare Binary Private Sub Select_Case_Multi() Dim city As String city = "dublin" ' Print the name of the airport based on the code to the ' Immediate Window (Ctrl + G). Select Case city Case "DUBLIN" Debug.Print "Europe" Case Else Debug.Print "The city is not valid." 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 :
- Record Macros in Excel.
- 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

In VBA, the Select Case Statement is an alternative to the If-Then statement, allowing you to test if conditions are met, running specific code for each condition. The Select Statement is preferable to the If Statement when there are multiple conditions to process.
Select Case Example
This example prompts the user with a YesNoCancel MessageBox and tests which option the user selected:
Sub Select_Case_Yes_No_Cancel()
Dim nResult As VbMsgBoxResult
nResult = MsgBox("...", vbYesNoCancel)
Select Case nResult
Case vbYes
MsgBox "Yes"
Case vbNo
MsgBox "No"
Case vbCancel
MsgBox "Cancel"
End Select
End Sub
Below we’ve written out the equivalent using an If Statement instead. You’ll notice that the Case Select Statement involves slightly less typing – this benefit is amplified when testing multiple criteria.
Sub If_Yes_No_Cancel()
Dim nResult As VbMsgBoxResult
nResult = MsgBox("...", vbYesNoCancel)
If nResult = vbYes Then
MsgBox "Yes"
ElseIf nResult = vbNo Then
MsgBox "No"
ElseIf nResult = vbCancel Then
MsgBox "Cancel"
End If
End Sub
Case Statement Syntax
The Select Case Statement syntax is as follows:
Select Case [Test Expression]
Case [Condition 1]
[Action if condition 1 is true]
Case [Condition 2]
[Action if condition 2 is true]
Case [Condition n]
[Action if condition n is true]
Case Else
[Action if none are true]
End Select
Where:
[Test Expression] – Is the value to evaluate. Usually this is a variable.
[Action if condition n is true] – Is just the code to run if the condition is met (just like with an If Statement)
[Condition n] – Is the condition to test. There are a lot of different ways to test conditions. We will discuss them below.
The Case Statement will execute the code for the FIRST condition that is found to be TRUE. If no condition is met then no code will be executed, unless the Else clause is added.
Select Case Criteria
Select Cases can be used to evaluate both numerical values and text. First we will discuss how to use Select Cases to evaluate numerical expressions.
Exact Match – Numbers
You can easily test for an exact match with a Case Statement:
Case 10
or add commas to test for exact matches with multiple numbers:
Case 20, 30, 40
Sub ExactMatch_Numbers()
Dim n As Integer
n = CInt(InputBox("..."))
Select Case n
Case 10
' If n is 10 Then
Case 20, 30, 40
' If n is 20/30/40 Then
Case Else
' If n is not 10/20/30/40 Then
End Select
End Sub
Ranges
You can test if a number falls within a range like so:
Case 55 To 74
This procedure will generate a letter score for a student based on their numerical score:
Sub Calc_Grade()
Dim Score As Integer
Dim LetterGrade As String
Score = InputBox("Enter Student Score")
Select Case Score
Case 90 To 100
LetterGrade = "A"
Case 80 To 90
LetterGrade = "B"
Case 70 To 80
LetterGrade = "C"
Case 60 To 70
LetterGrade = "D"
Case Else
LetterGrade = "F"
End Select
MsgBox "The Student's Grade is: " & LetterGrade
End Sub
You can also test ranges with the Case Is
Select Case Is
Case is < 55
'Do Nothing
Case <= 74
MsgBox "In Range"
Remember that the Case Statement will only execute code for ONLY the first match.
This procedure will calculate a student’s grade using the Case Is instead of Case To.
Sub Select_Case_Is_Grade()
Dim Score As Integer
Dim LetterGrade As String
Score = InputBox("Enter Student Score")
Select Case Score
Case Is >= 90
LetterGrade = "A"
Case Is >= 80
LetterGrade = "B"
Case Is >= 70
LetterGrade = "C"
Case Is >= 60
LetterGrade = "D"
Case Else
LetterGrade = "F"
End Select
MsgBox "The Student's Grade is: " & LetterGrade
End Sub

Case Else
You can add “Case Else” to the end of your Case Statement to do something if no conditions are met:
Case Else
See the end of the previous code example to see how Case Else can be used.
Select Case – Text & the Like Operator
So far our Select Case examples have worked only with numbers. You can also use Select Case statements with text.
Exact Match – Text
You can test if the expression matches an exact phrase like this:
Case "Beets"
Or use commas to test if the expression exactly matches more than one phrase:
Case "Apple", "Banana", "Orange"
Putting it together looks like:
Sub ExactMatch_Food()
Select Case Range("a1").Value
Case "Beets"
MsgBox "Vegetable"
Case "Apple", "Banana", "Orange"
MsgBox "Fruit"
End Select
End Sub
VBA Programming | Code Generator does work for you!
Upper and Lower Case
By default, VBA is Case Sensitive. This means that VBA considers “Text” different than “text”. To turn case-sensitivity off add Option Compare Text to the top of your module:
Option Compare Text
This example will make the Case Select case-insensitive when working with text:
Option Compare Text
Sub ExactMatch_Food()
Select Case Range("a1").Value
Case "Beets"
MsgBox "Vegetable"
Case "Apple", "Banana", "Orange"
MsgBox "Fruit"
End Select
End Sub
Case Like
The Like Operator allows you to make inexact comparisons. If the text matches, Like returns TRUE, if it doesn’t match it returns FALSE. This makes the Like operator easy to use with If Statements, however it won’t work as easily with Case Statements.
Case Like – A Failed Test
The following code demonstrates that the Like Operator doesn’t work with Select Case:
Sub Select_Case_Like_DoesnotWork()
Dim word As String
word = "COCOA"
Select Case word
Case word Like "*C*C*"
MsgBox "Good"
Case Else
MsgBox "Not Good"
End Select
End Sub
Case Like – The Correct Way
However, we can add in the TRUE expression to make the Select Statement work with the Like Operator:
Sub Select_Case_Like_CorrectWay()
Dim word As String
word = "COCOA"
Select Case True
Case word Like "*C*C*"
MsgBox "Good"
Case Else
MsgBox "Not Good"
End Select
End Sub
Case – Colon
When using a Case Statement you can add as many lines of code as you’d like to run with each condition. However, if you only need to run one line of code. You can use a Colon ( : ) to write everything on the same line.
Here is the same student grade example as before, except using a colon to shorten the code:
Sub Calc_Grade_colon()
Dim Score As Integer
Dim LetterGrade As String
Score = InputBox("Enter Student Score")
Select Case Score
Case 90 To 100: LetterGrade = "A"
Case 80 To 90: LetterGrade = "B"
Case 70 To 80: LetterGrade = "C"
Case 60 To 70: LetterGrade = "D"
Case Else: LetterGrade = "F"
End Select
MsgBox "The Student's Grade is: " & LetterGrade
End Sub
Case Select – And / Or – Multiple Conditions
You can use the And / Or Operators to test additional criteria along with the Select Case.
In this example we are using a Select Case on the variable ‘age’, but we also want to test sex. So we use the And Operator to perform the more complex test:
Sub NestedSelectCase()
Dim sex As String
Dim age As Integer
sex = "male" ' or female
age = 15
Select Case age
Case Is < 20 And sex = "male"
Msgbox "Male under 20"
Case Is < 20 And sex = "female"
Msgbox "Female under 20"
Case Is >= 20 And sex = "male"
Msgbox "Male over 20"
Case Is >= 20 And sex = "female"
Msgbox "Female over 20"
End Select
End Sub
Nested Case Statements
Just like If Statements, you can nest Case Statements inside each other:
Sub NestedSelectCase()
Dim sex As String
Dim age As Integer
sex = "male" ' or female
age = 15
Select Case age
Case Is < 20
Select Case sex
Case "male"
MsgBox "Male under 20"
Case "female"
MsgBox "Female under 20"
End Select
Case Is >= 20 And sex = "female"
Select Case sex
Case "male"
MsgBox "Male over 20"
Case "female"
MsgBox "Female over 20"
End Select
End Select
End Sub

Case Statement vs. If Statement
The more conditions to test, the more useful the Case Statement is compared to an If Statement. Let’s look at an example.
Here is the code required to test if a worksheet name equals a set of values using an If Statement:
If Name = "Budget" Or Name = "Forecast" Or Name = "Trailing12" Or _
Name = "Flex" Or Name = "OtherRatios" Or Name = "Comparison" Or _
Name = "BudReview" Or Name = "P&L_Review" Or Name = "Other" Then
'Do something
End If
Here is the same code using a Select Statement instead:
Select Case Name
Case "Budget", "Forecast", "Trailing12", "Flex", "OtherRatios", _
"Comparison", "BudReview", "P&L_Review", "Other"
'Do Something
End Select
You can see it’s much easier to use a Select Statement in this scenario. It’s significantly less typing, and it’s much easier to read.
VBA Select Case Examples
Ex 1. Case Statement User Defined Function (UDF)
Let’s replicate our grade calculation example above and create a UDF to calculate a student’s score:
Function GetGrade(Score As Integer) As String
Select Case Score
Case 90 To 100
GetGrade = "A"
Case 80 To 90
GetGrade = "B"
Case 70 To 80
GetGrade = "C"
Case 60 To 70
GetGrade = "D"
Case Else
GetGrade = "F"
End Select
End Function
Now we can use Function GetGrade in our Excel worksheet to quickly calculate student grades:
Ex 2. Test Sheet Name / Loop Case Statement
This code will loop through all worksheets in a workbook, UnProtecting sheets that meet certain criteria:
Sub Case_UnProtectSheet()
Dim ws As Worksheet
For Each ws In Worksheets
Select Case ws.Name 'List of all sheets with Ratios
Case "Budget", "Forecast", "Trailing12", "Flex", "OtherRatios", _
"Comparison", "BudReview", "P&L_Review", "Other"
ws.Unprotect
End Select
Next ws
End Sub
Ex 3. Select Case – Cell Value
This example will test a student’s score in a cell, outputting the letter grade directly to the cell to the right.
Sub TestCellValue()
Dim cell As Range
Set cell = Range("C1")
Select Case cell.Value
Case 90 To 100
cell.Offset(0, 1) = "A"
Case 80 To 90
cell.Offset(0, 1) = "B"
Case 70 To 80
cell.Offset(0, 1) = "C"
Case 60 To 80
cell.Offset(0, 1) = "D"
End Select
End Sub
Ex 4. Select Case – Dates
This Case Select example is a Function that tests which quarter a date fall into.
Sub TestDate ()
MsgBox GetQuarter(CDate("7/20/2019"))
End Sub
Function GetQuarter(dt As Date) As Integer
Dim sht As Worksheet
Select Case dt
Case CDate("01/01/2019") To CDate("03/31/2019")
GetQuarter = 1
Case CDate("04/01/2019") To CDate("06/30/2019")
GetQuarter = 2
Case CDate("07/01/2019") To CDate("09/30/2019")
GetQuarter = 3
Case CDate("10/01/2019") To CDate("12/31/2019")
GetQuarter = 4
End Select
End Function
Because it’s a function, you can use it as a function inside Excel:
Ex. 5 Check if Number is Odd or Even
This example tests if a number is odd or even.
Sub CheckOddEven()
Dim n As Integer
n = InputBox("Enter a number")
Select Case n Mod 2
Case 0
MsgBox "The number is even."
Case 1
MsgBox "The number is odd."
End Select
End Sub
Ex. 6 Test if Date is on Weekday or Weekend
These examples will test if a date falls on a weekday or a weekend.
Sub CheckWeekDay()
Dim dt As Date
dt = CDate("1/1/2020")
Select Case Weekday(dt)

Excel VBA has the IF Then Else construct that you can use to analyze multiple conditions and execute codes based on these conditions.
Another similar construct that allows you to check for multiple conditions is the SELECT CASE statement.
Select Case is useful when you have three or more conditions that you want to check. You can also use this with two conditions (but I feel If Then Else is easier to use in those cases).
A simple example where the Select Case statement is useful when you want to get the grade of a student based on the marks he/she has scored (covered as an example later in this tutorial).
Note: All the example codes covered in this tutorial are meant to be placed in a module in VBA.
Select Case Syntax
Below is the syntax of Select Case in Excel VBA:
Select Case Test_Expression Case Value_1 Code Block when Test_Expression = Value_1 Case Value_2 Code Block when Test_Expression = Value_2 Case Value_3 Code Block when Test_Expression = Value_3 Case Else Code Block when none of the case conditions are met End Select
- Test_Expression: This is the expression whose value we analyze by using different cases (explained better with the examples below).
- Condition_1, Condition_2,…: These are the conditions on which the text expression is tested. If it meets the condition, then the code block for the given condition is executed.
For every Select Case statement that you use, you need to use the End Select statement.
Note: As soon as a condition is met, VBA exits the select case construct. So if you have five conditions, and the second condition is met, VBA would exit Select Case – and the rest of the conditions will not be tested.
Select Case Examples
Now to better understand how to use Select Case statement in VBA, let’s go through a few examples.
Note that most of the examples in this tutorial are meant to explain the concept. These may or may not be the best way to get the work done.
Let’s start with a simple example of see how Select Case allows us to check for conditions.
Example 1 – Check the Numbers
In the below example, the code asks the user to enter any number between 1 and 5, and then shows a message box with the number the user entered.
Sub CheckNumber() Dim UserInput As Integer UserInput = InputBox("Please enter a number between 1 and 5") Select Case UserInput Case 1 MsgBox "You entered 1" Case 2 MsgBox "You entered 2" Case 3 MsgBox "You entered 3" Case 4 MsgBox "You entered 4" Case 5 MsgBox "You entered 5" End Select End Sub
Note that this code is far from useful and is not even foolproof. For example, if you enter 6 or any string, it would do nothing. But as I mentioned, my intent here is to showcase how Select Case works.
Example 2 – Using Select Case with IS Condition
You can use an IS condition with the Select Case construct to check for the value of numbers.
The below code checks whether the input number is greater than 100 or not.
Sub CheckNumber() Dim UserInput As Integer UserInput = InputBox("Please enter a number") Select Case UserInput Case Is < 100 MsgBox "You entered a number less than 100" Case Is >= 100 MsgBox "You entered a number more than (or equal to) 100" End Select End Sub
Example 3 – Using Case Else to Catch All
In the above example, I used two conditions (less than 100 or greater than or equal to 100).
Instead of the second case with a condition, you can also use Case Else.
Case Else acts as a catch-all and anything which doesn’t fall into any of the previous cases is treated by the Case Else.
Below is an example code where I have used Case Else:
Sub CheckNumber() Dim UserInput As Integer UserInput = InputBox("Please enter a number") Select Case UserInput Case Is < 100 MsgBox "You entered a number less than 100" Case Else MsgBox "You entered a number more than (or equal to) 100" End Select End Sub
Example 4 – Using a Range of Numbers
In Select Case, you can also check for a range of numbers.
The below code asks for an input and shows a message box based on the value.
Sub CheckNumber() Dim UserInput As Integer UserInput = InputBox("Please enter a number between 1 and 100") Select Case UserInput Case 1 To 25 MsgBox "You entered a number less than 25" Case 26 To 50 MsgBox "You entered a number between 26 and 50" Case 51 To 75 MsgBox "You entered a number between 51 and 75" Case 75 To 100 MsgBox "You entered a number more than 75" End Select End Sub
Example 5 – Get the Grade based on the Marks Scored
So far we have seen basic examples (which are not really useful in the practical world).
Here is an example which is closer to a real-world example where you can use Select Case in Excel VBA.
The following code will give you the grade a student gets based on the marks in an exam.
Sub Grade() Dim StudentMarks As Integer Dim FinalGrade As String StudentMarks = InputBox("Enter Marks") Select Case StudentMarks Case Is < 33 FinalGrade = "F" Case 33 To 50 FinalGrade = "E" Case 51 To 60 FinalGrade = "D" Case 60 To 70 FinalGrade = "C" Case 70 To 90 FinalGrade = "B" Case 90 To 100 FinalGrade = "A" End Select MsgBox "The Grade is " & FinalGrade End Sub
The above code asks the user for the marks and based on it, shows a message box with the final grade.
In the above code, I have specified all the conditions – for marks 0 – 100.
Another way to use Select Case is to use a Case Else at the end. This is useful when you have accounted for all the conditions and then specify what to do when none of the conditions is met.
The below code is a variation of the Grade code with a minor change. In the end, it has a Case else statement, which will be executed when none of the above conditions are true.
Sub CheckOddEven() Dim StudentMarks As Integer Dim FinalGrade As String StudentMarks = InputBox("Enter Marks") Select Case StudentMarks Case Is < 33 FinalGrade = "F" Case 33 To 50 FinalGrade = "E" Case 51 To 60 FinalGrade = "D" Case 60 To 70 FinalGrade = "C" Case 70 To 90 FinalGrade = "B" Case Else FinalGrade = "A" End Select MsgBox "The Grade is " & FinalGrade End Sub
Example 6 – Creating a Custom Function (UDF) using Select Case
In the above example, the code asked the user for the marks input.
You can also create a custom function (User Defined Function) that can be used just like any regular worksheet function, and which will return the grade of the students.
Below is the code that will create the custom formula:
Function GetGrade(StudentMarks As Integer) Dim FinalGrade As String Select Case StudentMarks Case Is < 33 FinalGrade = "F" Case 33 To 50 FinalGrade = "E" Case 51 To 60 FinalGrade = "D" Case 60 To 70 FinalGrade = "C" Case 70 To 90 FinalGrade = "B" Case Else FinalGrade = "A" End Select GetGrade = FinalGrade End Function
Once you have this code in the module, you can use the function GetGrade in the worksheet as shown below.
Example 7 – Check ODD / EVEN with Select Case
Below is an example code where I check whether the number in cell A1 is odd or even.
Sub CheckOddEven() CheckValue = Range("A1").Value Select Case (CheckValue Mod 2) = 0 Case True MsgBox "The number is even" Case False MsgBox "The number is odd" End Select End Sub
Example 8 – Checking for Weekday/Weekend (Multiple Conditions)
You can also use Select Case to check for multiple values in the same case.
For example, the below code uses the current date to show whether today is a weekday or weekend (where weekend days are Saturday and Sunday)
Sub CheckWeekday() Select Case Weekday(Now) Case 1, 7 MsgBox "Today is a Weekend" Case Else MsgBox "Today is a Weekday" End Select End Sub
In the above code, we check for two conditions (1 and 7) in the same case.
Note: Weekday function returns 1 for Sunday and 7 for Saturday.
Example 9 – Nested Select Case Statements
You can also nest one Select Case statement within other.
Below is a code that checks whether a day is a weekday or a weekend, and if it’s a weekend, then it will display whether it’s a Saturday or a Sunday.
Sub CheckWeekday() Select Case Weekday(Now) Case 1, 7 Select Case Weekday(Now) Case 1 MsgBox "Today is Sunday" Case Else MsgBox "Today is Saturday" End Select Case Else MsgBox "Today is a Weekday" End Select End Sub
In the above code, I have nested the Select Case to check whether the weekend is a Saturday or a Sunday.
Note: The example shown above is to explain the concept. This is not the best or the most practical way to find out weekday/weekend.
Example 10 – Checking Text String with Select Case
You can check specific strings using Select Case and then execute code based on it.
In the example code below, it asks the user to enter their department name and shows the name of the person they should connect with for onboarding.
Sub OnboardConnect() Dim Department As String Department = InputBox("Enter Your Department Name") Select Case Department Case "Marketing" MsgBox "Please connect with Bob Raines for Onboarding" Case "Finance" MsgBox "Please connect with Patricia Cruz for Onboarding" Case "HR" MsgBox "Please connect with Oliver Rand for Onboarding" Case "Admin" MsgBox "Please connect with Helen Hume for Onboarding" Case Else MsgBox "Please connect with Tony Randall for Onboarding" End Select End Sub
Hope all the examples above were helpful in understanding the concept and application of Select Case in Excel VBA.

Key Points
- With SELECT CASE, you can test multiple conditions, especially when you are working on more than two.
- The code you write with SELECT CASE is way more structured than standard conditional code.
- It is easier to modify it when you need to adjust one or more of the values in the code.
What is VBA Select Case
VBA SELECT CASE is a statement to test multiple conditions. In this statement, you can specify one condition and then specify a code to execute if that condition is true and then specify a second condition and a code to run if that condition is true. In this way, you can specify multiple conditions and multiple statements.
The syntax for select case
Below is the syntax that you need to follow to write a select case statement.
Select Case Test Expression
Case (Condition to Test)
Statement1 [Line of Code to Run if CASE 1 is TRUE]
Case (Condition to Test)
Statement1 [Line of Code to Run if CASE 2 is TRUE]
Case Else
Statement [Line of Code to Run if no CASE is TRUE]
End Select
In SELECT CASE syntax starts with the keyword “Select” and ends with “End Select”. To understand its syntax, we need to split it into four parts:
- In the FIRST part, you need to specify the “Test Expression” on which all the conditions get tests.
- After that, in the SECOND part, you need to specify the case to test (that means condition to test).
- Now in the THIRD part, you need to write another case where you need to test if the condition in the second part is not TRUE.
- In the end, in the FOURTH part, you need to specify an outcome that should come when both the above cases are not TRUE.
A simple example to understand a select case statement
The syntax of the SELECT CASE is self-explanatory and quite easy to follow while writing code. But let’s take an example and understand it completely. Below you have a simple code to test the value from cell A1.
Sub SelectCaseExample1()
Select Case Range("A1").Value
Case "Yes"
MsgBox "It's a Yes."
Case "No"
MsgBox "It's a No"
Case Else
MsgBox "Can't Say"
End Select
End Sub
Now let’s understand this code with each line:
- FIRST, you have the SELECT CASE keyword and the cell A1 to use as an expression for testing the condition.
- SECOND, you have the keyword CASE and the condition (“YES”) to check from cell A1 and code to show a message box with the message “It’s a Yes” if the condition mentioned in the case1 is true.
- THIRD, you again have the keyword case and the condition (“No”) to check from cell A1 and code to show a message box with the message “It’s a No” if the condition mentioned in case two is true.
- FOURTH, you have the keyword CASE ELSE and a line of code to show a message box with a message “Can’t Say” if none of the cases are true.
- FIFTH, you have the END SELECT keyword to end the SELECT CASE statement.

Important Points
- It can test multiple conditions and execute a line of code based on the result.
- You can use comparison operators (=, >, <, <>, >=, <=) while testing for a condition by using the Is keyword.
- You can use a comma to test more than one condition within a single case.
- You can also use a range of numbers while testing a condition in a single case.
- When one condition is met, VBA stops to test the rest of the cases from the statement.
- You can also add a case else section at the end to execute a line of code when none of the conditions are met.
- You can skip using the CASE END statement.
More Examples to use Select Case
It’s time to use the SELECT CASE in different ways, and below are some of the useful and essential examples that you can learn.
100 Excel Macro Examples
1. Select Case with Numbers
While writing a VBA code for the SELECT CASE statement, you can use operators to compare values. Now in the below code, you have >,<, and = operators to test the conditions.
Sub SelectCaseExample1()
Select Case Range("A1").Value
Case Is >= 45
MsgBox "Pass"
Case Is < 45
MsgBox "Fail"
End Select
End Sub
- The first case in this statement checks if the value from cell A1 is greater than or equal to 45 or not and returns a message box with the message “Pass”.
- And the second case in the statement checks if the value from cell A1 is lower than 45 and returns a message box with the message “Fail”.
2. Select Case with a Range of Numbers
You can also use a range of numbers to test a condition. In the below code, you have a condition with a range of numbers in each case to test.
Sub SelectCaseExample2()
Select Case Range(“A1”).Value
Case 45 To 100
MsgBox “Pass”
Case 0 To 44
MsgBox “Fail”
Case Else
MsgBox “Out of Range”
End Select
End Sub
- The first case in the statement checks the number from cell A1 using the range of numbers from 45 to 100 and returns the “Pass” if the value falls under this range.
- The second statement has a range of 0 to 44 to test with the value from cell A1 and returns “Fail” if the value falls under this range.
- The third statement is case else show a message box with the message “Out of Range” if cases one and two are false.
3. Using the Colon Operator
While writing code for the SELECT CASE, you can use colon operators to write the entire case in one line.
In the below code, the line starts with the case and then the condition to test and then a colon, and then the statement to run in that case is true.
Sub SelectCaseExample3()
Select Case Range(“A1”).Value
Case 45 To 100: MsgBox “Pass”
Case 0 To 44: MsgBox “Fail”
Case Else: MsgBox “Out of Range”
End Select
End Sub
4. Use Select Case with Multiple Conditions
Just like defining a range for a case, you can also specify multiple values to test for the condition. In the below code, each case has three numbers to test.
Sub SelectCaseExample()
Select Case Range("A1").Value
Case 1, 3, 5
MsgBox "Yes"
Case 2, 4, 6
MsgBox "No"
Case Else
MsgBox "Out of range"
End Select
End Sub
- The first case of this code will test the value from the cell if it is 1, 3, or 5 and will return “Yes” in a message box.
- And the second case of this code will test the value from cell A1 if it’s 2, 4, or 6.
5. Using Select Case in a Custom Function
You can also use the SELECT CASE while writing code for a VBA Function.
Function udfGrade(student_marks As Integer)
Dim myGrade As String
Select Case student_marks
Case Is < 40: myGrade = “Bad”
Case 41 To 50: myGrade = “Average”
Case 51 To 60: myGrade = “Good”
Case 61 To 80: myGrade = “Very Good”
Case 81 To 100: myGrade = “Excellent”
End Select
udfGrade = myGrade
End Function
In the above function, it has five cases to check for the score of the students from a cell. All 5 cases use a range of numbers and return the value defined in the statement.
6. Using Select Case from Nested Conditions
You can also create a nested condition statement. What I’m trying to say is you can write a code to test multiple conditions with the select case.
Imagine if you want to write a code that can test conditions based on the values from two different cells.
Sub SelectCaseStatement()
Select Case Range("A2")
Case "Boy"
Select Case Range("B2")
Case "Commerce": MsgBox "Boy (Commerce)"
Case "Science": MsgBox "Boy (Science)"
End Select
Case "Girl"
Select Case Range("B2")
Case "Commerce": MsgBox "Girl (Commerce)"
Case "Science": MsgBox "Girl (Science)"
End Select
End Select
End Sub
In the above code, you have three select case statements. There is one main statement that checks for the value from the cell A2 if it is “Boy” or “Girl”.
And then, based on the result, two more statements run and check for the value from cell B2 if it is Commerce or Science.
SELECT CASE Vs. IF THEN ELSE Statement
- When you want to test multiple conditions, it’s easy to write a code using the SELECT CASE instead of IF-THEN.
- Even it is easy to edit and make changes in a SELECT CASE statement compared to IF-THEN.
Select Case Statement of Excel VBA
The Select Case VBA statement compares an expression with multiple Case statements containing conditions. If a match is found in any of the Case statements, the condition is said to be true. Further, if a condition is true, its corresponding code is executed and no more Case statements are tested. However, if a match is not found in any of the Case statements, the conditions are said to be false. In this case, the code of the Case Else statement is executed.
For example, an employee is asked to rate the work-life balance of his organization on a scale of 10. Further, his input will be compared with the following three conditions (or possible outcomes):
- If the input is between 1 and 3 (both inclusive), display the message “the work-life balance is poor.”
- If the input is between 4 and 6 (both inclusive), display the message “the work-life balance is reasonable.”
- If the input is between 7 and 10 (both inclusive), display the message “the work-life balance is healthy.”
The message of only that condition will display, which matches the input entered by the employee. Note that the expression can either be entered directly in a Select Case structure or collected from the user as an input.
The purpose of using the Select Case statement in VBA is to execute different codes based on the fulfillment or non-fulfillment of different conditions. The Select Case statement is used to evaluate (or test) three or more conditions. It is a substitute for the If Then Else statement of VBA and the nested IF statement of Excel.

Syntax of the Select Case Statement of Excel VBA
The Select Case statement in VBA is similar to the Switch Case statement used in programming languages like Java, C#, PHP, etc. The syntax of the Select Case statement of Excel VBA is given as follows:
Select [Case] Expression for testing [Case] List of Expression Statements (Case 1, Case 2, Case 3 and so on...) Case Else (Else Statements) End Select End Sub
The Select Case statement of Excel VBA accepts the following arguments:
- Expression for testing: This is a single expression that is to be compared with the different Cases. It can either be a numeric or textual expression. So, it can evaluate to a character, integer, Boolean, object, string, etc.
- List of expressions: This is the list of expressions (called Case statements) against which the “expression for testing” is compared. Excel VBA looks for an exact match within these Case statements. These Case statements consist of one or more possible outcomes (values or conditions) that may or may not match the “expression for testing.” If there are multiple expressions (or values) within a single Case, they must be separated by commas. The following keywords can be used in Case statements:
- The To keyword should be used when a range of values needs to be specified in a Case statement. The value preceding the To keyword should be less than or equal to the value succeeding this keyword.
- The Is keyword should be used when a logical operatorLogical operators in excel are also known as the comparison operators and they are used to compare two or more values, the return output given by these operators are either true or false, we get true value when the conditions match the criteria and false as a result when the conditions do not match the criteria.read more (=, <>, <, >, <= or >=) needs to be entered in a Case statement. This keyword should be inserted before the logical operator.
- Statements: This is one or more codes succeeding the “list of expressions.” Only that code is executed for which the “expression for testing” matches the “list of expressions.”
- Case Else statement: This consists of one or more codes (or statements), which are executed when all the Case statements (or list of expressions) are false.
- End Select: It closes the Select Case structure. Every Select Case statement must necessarily have an End Select statement.
The “expression for testing,” “list of expressions,” and End Select clauses are required in a Select Case construction. However, the “statements” and Case Else statements are optional in the given syntax.
Note 1: In a Select Case statement in VBA, each Case statement is compared with the “expression for testing.” Once a condition is met (or the Case statement is matched), no further Case statements are tested. However, if a condition is false (or the Case statement does not match), the next Case statement is tested.
The testing of Case statements (or conditions) continues till one of the specified conditions is met or till the Case Else or the End Select statement. If none of the tested conditions is true and there is no Case Else statement, control passes to the End Select statement.
Note 2: If the “expression for testing” matches more than one Case statement, only the code of the first such match is executed.
How to use the Select Case Statement of Excel VBA?
The Select Case statement is a feature of Excel VBA. One can access VBA from the “visual basic” option of the Developer tab of ExcelEnabling the developer tab in excel can help the user perform various functions for VBA, Macros and Add-ins like importing and exporting XML, designing forms, etc. This tab is disabled by default on excel; thus, the user needs to enable it first from the options menu.read more. In this tab, the user-defined functions (UDF) and their codes can be created.
The Select Case statement of VBA should be used in place of the nested IF statementIn Excel, multiple IF conditions are IF statements that are contained within another IF statement. They are used to test multiple conditions at the same time and return distinct values. Additional IF statements can be included in the ‘value if true’ and ‘value if false’ arguments of a standard IF formula.read more of Excel. This is because the former is easier to understand and execute than the latter.
The steps to use the Select Case statement of VBA are listed as follows:
- Create a command button and place it in the Excel worksheet. When the command button is clicked, a macroA macro in excel is a series of instructions in the form of code that helps automate manual tasks, thereby saving time. Excel executes those instructions in a step-by-step manner on the given data. For example, it can be used to automate repetitive tasks such as summation, cell formatting, information copying, etc. thereby rapidly replacing repetitious operations with a few clicks.
read more runs. The running of the macro performs an action. - Right-click the command button and choose the option “view code.” The Visual Basic Editor opens.
- Enter the code between the CommandButton function and End Sub.
- Debug and compile the code to identify the syntax errors.
- Change the input values to observe the different outputs.
Note 1: The user-defined functions (UDF) are customized functions that cater to the specific needs of the user.
Note 2: Every time the input is changed (in point e), the “expression for testing” changes. As a result, the conditions that match this expression change. Hence, different codes are executed each time the input values change.

Example #1–“Expression for Testing” is Entered Directly
In the following code, the “expression for testing” is A=20 and the Case statements are 10, 20, 30, and 40. There is also a Case Else statement in this code.
Private Sub Selcaseexmample () Dim A As Integer A = 20 Select Case A Case 10 MsgBox "First Case is matched!" Case 20 MsgBox "The Second Case is matched!" Case 30 MsgBox "Third Case is matched in Select Case!" Case 40 MsgBox "Fourth Case is matched in Select Case!" Case Else MsgBox "None of the Cases match!" End Select End Sub
On running the preceding code, the following output is obtained.
Explanation: The expression A=20 is compared with the four Case statements 10, 20, 30, and 40. A match is found in the second Case statement (Case 20). Consequently, the message of the second Case statement is displayed, which is “the second Case is matched.”
Had the expression not matched with any of the Case statements, the message of the Case Else statement would have been displayed.
Note: The MsgBox function of VBA displays a dialog box containing a customized message.
Example #2–“Expression for Testing” is Compared with a Range of Values Using the “To” Keyword
In the following code, the “expression for testing” is collected from the user with the help of the InputBox function of VBA. There are four Case statements, namely Case 1 To 36, Case 37 To 55, Case 56 To 80, and Case 81 To 100. There is also a Case Else statement in the code.
Private Sub Selcasetoexample () Dim studentmarks As Integer studentmarks = InputBox("Enter marks between 1 to 100.") Select Case studentmarks Case 1 To 36 MsgBox "Fail!" Case 37 To 55 MsgBox "C Grade" Case 56 To 80 MsgBox "B Grade" Case 81 To 100 MsgBox "A Grade" Case Else MsgBox "Out of range" End Select End Sub
On running the preceding code, the user is asked for input. Assume that the user enters 90. So, the following output is obtained.
Explanation: The Case statements of the preceding code contain a range of values. Notice that in the code, each number preceding the To keyword is smaller than the number succeeding this keyword.
The “expression for testing” is entered as 90 by the user. This expression matches the fourth Case statement (Case 81 to 100). So, the code in this Case statement is executed. Hence, the message “A grade” is returned by VBA. This output is displayed in a dialog box due to the usage of the MsgBox function in the code.
Both numbers (preceding and succeeding the To keyword) of the range are inclusive. So, had the user entered 81, it would have again matched with the fourth Case statement. However, had a number greater than 100 been entered, the output would have been “out of range.” This message is defined in the Case Else statement of the code.
Note: The InputBox function collects the input from the user through a dialog box. The message shown in this dialog box is the same as that entered in the InputBox function of the code.
Example #3–“Expression for Testing” is Compared with Numbers Using the “Is” Keyword
In the following code, the “expression for testing” is collected from the user. There are two Case statements, namely Case Is < 200 and Case Is >= 200. There is no Case Else statement in the code.
Sub CheckNumber() Dim NumInput As Integer NumInput = InputBox("Please enter a number.") Select Case NumInput Case Is < 200 MsgBox "You entered a number less than 200" Case Is >= 200 MsgBox "You entered a number greater than or equal to 200" End Select End Sub
On running the preceding code, a dialog box containing the message “please enter a number” is displayed. Assume that the user enters 200. So, the following output is displayed.
Explanation: Observe that the two logical operators (< and >=) in the code are preceded by the “Is” keyword. Had this keyword not been supplied, VBA would have automatically inserted it before the logical operators.
The “expression for testing” is entered by the user as 200. This expression is compared with the two Case statements of the preceding code. A match is found in the second Case statement. This is because 200 is not greater than but is equal to 200.
Notice that there is no Case Else statement in the preceding code. This is because whatever number the user enters, it falls within either of the two Case statements. So, one of the two Case statements will always be true. Hence, the Case Else statement is not required as it runs only when all Case statements evaluate to false.
Example #4–“Expression for Testing” is Entered in a Cell and Evaluated by the Command Button
In the following code, the “expression for testing” is taken from cell A1 of the Excel worksheet. There are three Case statements and one Case Else statement.
Sub color() Dim color As String color = Range("A1").Value Select Case color Case "Red", "Green", "Yellow" Range("B1").Value = 1 Case "White", "Black", "Brown" Range("B1").Value = 2 Case "Blue", "Sky Blue" Range("B1").Value = 3 Case Else Range("B1").Value = 4 End Select End Sub
Further, a command button has been created in the worksheet with the help of ActiveX controls. The input entered in cell A1, the command button, and the output obtained in cell B1 are shown in the following image.
Explanation: The preceding code is executed by clicking the command button of the Excel worksheet. Notice that multiple expressions of each Case statement are separated by commas (like “Red”, “Green”, “Yellow”).
The “expression for testing” is entered as “pink” in cell A1. This expression matches none of the three Case statements specified in the code. Consequently, the code of the Case Else statement is executed. So, the output in cell B1 is 4.
Had the user entered a color (in cell A1) specified in any of the three Case statements, the corresponding code would have run. For instance, had the user entered “White” in cell A1 (without the double quotes and with “W” capital), the output in cell B1 would have been 2.
Hence, a change in the input of cell A1 causes the output of cell B1 to change.
Example #5–“Expression for Testing” is Divided by 2 with the MOD Operator of VBA
In the following code, the “expression for testing” is collected from the user. There are two Case statements, namely Case True and Case False. The Case Else statement is not there in the code.
Sub CheckOddEven() CheckValue = InputBox("Enter a number.") Select Case (CheckValue Mod 2) = 0 Case True MsgBox "The number is even" Case False MsgBox "The number is odd" End Select End Sub
On running the preceding code, a dialog box with the message “enter the number” is displayed. Assume that the user enters 10. The output obtained is shown in the following image.
Explanation: The “expression for testing” entered by the user is 10. This expression is divided by 2 with the help of the MOD operatorVBA MOD is the same as the application in mathematics. When a number is divided by its divisor, this function gives us the remainder from the division. However, it is not a function in VBA; rather it is an operator.read more. If the remainder is equal to zero, the number is divisible by 2. Such a number is even. If the remainder is not equal to zero, the number is not divisible by 2 and is odd.
Since 10 is divisible by 2, the code of the Case True statement is executed. Hence, the output is the message “the number is even.” Notice that a Case Else statement is not required in the preceding code. This is because either of the two Case statements will be true at all times.
Note: The MOD operator of VBA divides one number by the other and returns the remainder as the output.
Example #6–Nested Select Case Statements Where “Expression for Testing” is the Current Date
In the following code, the “expression for testing” is the current date. There are two Select Case statements [Select Case Weekday (Now) and Case 1,7], one Case Statement (Case 1), and two Case Else statements.
Sub TestWeekday() Select Case Weekday(Now) Case 1, 7 Select Case Weekday(Now) Case 1 MsgBox "Today is Sunday" Case Else MsgBox "Today is Saturday" End Select Case Else MsgBox "Today is a Weekday" End Select End Sub
On running the preceding code, the output obtained is shown in the following image.
Explanation: The inner Select Case statement (Case 1, 7) is the Case statement of the outer Select Case statement [Select Case Weekday (Now)]. The outer Select Case statement checks whether the current date is a weekday, Saturday or Sunday.
When the NOW VBA functionNOW is a date and time function in VBA which is used to get the current system date and time. VBA Now function does not takes any arguments and the return output for this function is date.read more is enclosed within the VBA WEEKDAY functionWeekday in VBA is a date and time function to identify the weekday of a given date provided as an input. This function returns an integer value from 1 to 7 range. There is an optional argument provided to this function which is the first day of the week.read more, the latter returns a day of the week that corresponds with the current date. If the output of the WEEKDAY function is 1, the message to be displayed is “today is Sunday.” If the output of the WEEKDAY function is 7, the message to be displayed is “today is Saturday.” This is because, in the preceding code, VBA considers 1 and 7 as Sunday and Saturday respectively.
The message “today is a weekday” will be returned when the output of the WEEKDAY function is other than 1 and 7. So, the second Case Else statement is executed when Case 1 (today is Sunday) and the first Case Else statements (today is Saturday) are false.
Since this article has been created on a weekday, the output of the Select Case statement is “today is a weekday.”
Note 1: The NOW function of VBA returns the current date and time. This function does not take any arguments. The WEEKDAY function of VBA returns the day of the week corresponding to the specified date.
Note 2: Every nested Select Case statement should necessarily contain a matching End Select statement.
The important points related to the Select Case statement of VBA are listed as follows:
- The Is keyword used in the Case statement and Case Else statement is different from the Is operator of VBA.
- The codes of the Select Case statement of VBA can run successfully if macros have been enabled.
- The “expression for testing” entered in the dialog box should be in accordance with the message of the InputBox function of VBA.
Note: To know more about enabling macrosTo enable macros simply means to run or execute a macro in a particular file in order to save the time spent on repetitive actions. To enable macros, select “enable all macros” from the “trust center” of the File tab (in the “options” button).

Frequently Asked Questions
1. Define the Select Case statement of Excel VBA.
The Select Case statement is used to compare an expression with multiple Case statements. If a Case statement matches the expression, the corresponding code is executed. However, if a Case statement does not match the expression, the next Case statement is evaluated.
The evaluation of Case statements continues till a match is found or till the Case Else or End Select statement. Once a match is found in any of the Case statements, no further Case statements are tested. The Case Else statement is optional and its code is executed when none of the Case statements is true.
Note: For details related to the working of the VBA Select Case statement, refer to the examples of this article.
2. How is the Select Case statement of Excel VBA written?
The steps to write the Select Case statement of Excel VBA are listed as follows:
a. Specify a single expression that needs to be compared with multiple Case statements. This expression can be numeric or textual. Note that the expression is evaluated only once and is stated at the beginning of the Select Case structure.
b. Specify the Case statements. Each Case statement should consist of one or more conditions (or possible outcomes) followed by a code. For stating multiple conditions within the same Case statements, use the comma as the separator.
c. Specify the Case Else statement. The code of this statement will be executed if none of the Case statements match the expression. Though it is optional to specify the Case Else statement, it is recommended to be included in the Select Case structure.
d. State the End Select statement. This statement is necessarily required as it terminates the Select Case structure. If no Case statement matches the expression and there is no Case Else statement, control passes to the End Select statement.
Note 1: If the expression (in point a) is to be collected as an input from the user, a customized message must be stated within the InputBox function of VBA.
Note 2: For more details related to the writing of the VBA Select Case statement, refer to the codes of the examples and their explanations given in this article.
3. Differentiate between the Select Case and If Then Else statements of Excel VBA.
The differences between the Select Case and If Then Else statements of Excel VBA are listed as follows:
a. The Select Case statement evaluates a single expression at a time, while the If Then Else statement can evaluate multiple expressions simultaneously.
b. The Select Case statement checks one expression for multiple possible outcomes, while the If Then Else statement checks multiple expressions for multiple possible outcomes.
c. In a Select Case statement, any number of Case statements can be included without impacting the readability of the code. In contrast, a lot of conditions tend to make the If Then Else statement unreadable.
d. It is easy to write, edit, and make changes to the Select Case statement. On the other hand, it is difficult to write, identify errors, and make changes to the If Then Else statement.
In both, Select Case and If Then Else statements, a code is executed depending on whether a condition is met or not. So, based on the requirement and convenience, one can choose either of the two statements.
