1. Reason for Data Validation Not Working Copy Paste in Excel

In this dataset, I am going to employ the Data Validation Feature in the Employ Name column to limit my entries.

Steps :

For this, I have selected Column B which contains the Employee Name.
Then, from the Data tab, I have selected Data Tools and finally selected Data Validation from there.

A dialogue box will appear.

Here, the Settings tab is open in the dialogue box.
After that, we have to select Validation criteria from Allow. Here, I have chosen Text length.
Next, I have to limit the range for validation. Here, I have allowed the data containing text from a minimum of 1 to a maximum of 8 characters for validation.

The Data Validation feature will be applied.
Followingly, I input data that does not satisfy the condition. Here, I wrote the value Labuchange from the Waiting List.

A warning message will be shown for the invalid data entry. As I input data that is invalid according to the Data Validation condition, it did not accept the value and a warning message has appeared.

But if you copy the value and paste it in the data validated column, it will accept the value and no warning message will appear.

This is a serious problem as our Data Validation is not working on copy-paste.

2. Creating Data Validation Using VBA to Work Copy Paste

In the case of solving the Excel Data Validation Not Working for Copy Paste problem, Visual Basic for Applications (VBA) is the only solution. We are going to explain the solution here.

Steps :

First of all, select the Developer tab.
Next, select Visual Basic.

A new window will appear.

Click on the Sheet in which you want to apply the Code. Here, I selected Sheet2 named VBA to apply the code.

Select the Worksheet from General and Change from Declarations to create a Private Sub.

Now, input the following code on how you want to validate the data.

My used code is mentioned below:

Private Sub Worksheet_Change(ByVal Target As Range)

    If Target.Column = 2 Then
        If Len(Target.Value) >= 8 Then
            MsgBox "Name is longer than 8. Undo!", vbCritical
            Application.Undo
        End If
    End If

End Sub

Then, check if the validation is working or not from the sheet.

Here, I have inserted the value from the D7 cell by copying and pasting it into B10. The value shows an Error alert according to the data validation condition. So, the warning box will appear.

This method also works perfectly if I input the data through the keyboard or any other process.

If you click OK, the cell will go back to its previous mode.

  Thanks for the appreciation.
  For columns A & B:
  From the Data tab, select Data Tools and pick Data Validation from there. This will open the Data validation feature. From there, mention the text length of minimum “1” to maximum “8”.
  
  For column C, follow the same procedure. Just in the maximum section, input “10”.

Hello, I have follwed the steps above and am running into an issue where the error message continues to “loop” and doesn’t let me change the text that is over the character limit. Is there a way to let a user go back and edit after the error message appears?

Hey Cole, did the loop issue get sorted ? i am also facing the same issue !

Hi dear NAIMUL HASAN ARIF, this article is the great and very helpful. Thank you for it.

But I think that in your code have some misunderstanding in here “Private Sub Worksheet_SelectionChange(ByVal Target As Range)”.
I think it should be like that “Private Sub Worksheet_Change(ByVal Target As Range)”. Because when I click the cell of the range which I choose in VBA code, excel show error message in the VBA code.

  Dear TURAN,
  Thanks for your valuable comment. That was an honest mistake from me. I have updated the error. I have also modified the code as I have found a simpler way to perform the same task.
