VBA Exit Sub or Function
In VBA, you can exit a Sub or Function, by using the Exit Sub or Exit Function commands.

Exit Function |
When the execution of the code comes to Exit Sub or Exit Function, it will exit a Sub or Function and continue with any other code execution.

Exit a Sub in VBA
You will see on the example what happens when we use the Exit Sub command in a Sub. We created a Sub ExitSub, which has the Exit Sub command inside. The Sub CallExitSub calls this Sub. Here is the code:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
Private Sub ExitSub() Dim i As Integer For i = 1 To 10 If i = 5 Then Exit Sub MsgBox "The value of i is" & i End If Next i End Sub Private Sub CallExitSub() Call ExitSub MsgBox "Exit Sub" End Sub |
In the ExitSub, we first enter the For Loop if the value of i is less than 10:
|
1 2 3 |
For i = 1 To 10 Next i |
After that we check if the value of i is equal to 5, using the If command. If the value is 5, we want to exit the Sub and return the Message box with the value of i:
|
1 2 3 4 |
If i = 5 Then Exit Sub MsgBox "The value of i is" & i End If |
If the condition is not met, the following statement increases i by 1 and enters in the For loop again:
|
1 |
Next i |
In the CallExitSub, we first call the Sub ExitSub:
|
1 |
Call ExitSub |
After that we return the Message box:
|
1 |
MsgBox "Exit Sub" |
If you run the CallExitSub, it will first call the ExitSub. If you execute this code in the debug mode, you will see that it will go through the loop 5 times. In the 5th iteration, the value of the variable i becomes 5 and the code enters in the If body. Now the Sub ExitSub is exited and returned to the CallExitSub. The next line is MsgBox “Exit Sub”:

As you can see, the ExitSub is exited right after Exit Sub command, so the MsgBox “The value of i is” & i will be never executed.
Exit a Function in VBA
Exiting a function in VBA is similar to exiting a Sub, just the command is Exit Function. In the example, we created the ExitFunc which returns an integer. The Sub CallExitFunction calls this function. Here is the code:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
Private Function ExitFunc() As Integer Dim i As Integer For i = 1 To 10 If i = 5 Then ExitFunc = i Exit Function End If Next i End Function Private Sub CallExitFunction() Dim intFunc As Integer intFunc = ExitFunction() MsgBox "The value of intFunc is " & intFunc End Sub |
In the ExitFunc, we first enter the For Loop if the value of i is less than 10:
|
1 2 3 |
For i = 1 To 10 Next i |
After that we check if the value of i is equal to 5, using the If command. If the value is 5, we assign the value of i to the function result and exit the function:
|
1 2 3 4 |
If i = 5 Then ExitFunc = i Exit Function End If |
If the condition is not met, the following statement increases i by 1 and enters in the For loop again:
|
1 |
Next i |
In the CallExitFunction, we first call the function ExitFunc: To do that we have to declare the variable intFunc type integer and assign the result of the ExitFunc function to it:
|
1 2 3 |
Dim intFunc As Integer intFunc = ExitFunction() |
After that we return the Message box with the value of intFunc:
|
1 |
MsgBox "The value of intFunc is " & intFunc |
If you run the CallExitFunction, it will first call the function ExitFunc. If you execute this code in the debug mode, you will see that it will go through the loop 5 times. In the 5th iteration, the value of the variable i becomes 5 and the code enters in the If body. Now the value of the ExitFunc becomes i and the function is exited and returned to the CallExitFunction. The next line is MsgBox “The value of intFunc is ” & intFunc:
