Problem and Solution of Data Validation Not Working Copy Paste in Excel

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_SelectionChange(ByVal Target As Range)
Dim ValidatedCells As Range
    Dim Cell As Range
    Set ValidatedCells = Intersect(Target, Target.Parent.Range("B:B"))
    If Not ValidatedCells Is Nothing Then
        For Each Cell In ValidatedCells
            If Not Len(Cell.Value) <= 8 Then
                MsgBox "The Name """ & Cell.Value & _
                """ inserted in " & Cell.Address & _
                " in column B was longer than 8. Undo!", vbCritical
                Application.Undo
                Exit Sub
            End If
        Next Cell
    End If
End Sub

Here, I created a Private Sub name Worksheet_Change, I declared two variables these are ValidatedCells and Cell as Range. Next, I used the Set method to keep the range where I want to apply validation.

Then, selected Column B for validation. I also mentioned the range here using the Range method.  I used the For loop in the nested IF statement to set the conditions Text Length of the selected range can’t be longer than 8. If it does not match the range, a warning box will appear to show a message through MsgBox  and Undo option will be available.

• Now, Save the code.

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

Here, I insert the value from the D7 cell by copying and pasting it in 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.
