Validate Excel Cell Input

Posted by sqlnow on June 3, 2010

You are doing many critical calculations in a single excel spreadsheet in our daily work, but what if you entered invalid data into the sheet? All the formulas entered will through some error. So can you really validate user inputs in excel?

Yes, you can!! This post demonstrates how to restrict incorrect inputs into a particular column. Here I will demonstrate how to validate a column where you can enter only Numeric values. Just follow these simple steps:

Press ALT + F11 key combination to open Visual Basic Editor >> double click on the Sheet you want to validate from the Project Window. Paste the below VBA code and save the spreadsheet and you are done with the requirement.

Private Sub Worksheet_Change(ByVal Target As Range)
 'do nothing if multiple cells edited
 If Target.Cells.Count > 1 Or IsEmpty(Target) Then Exit Sub
With Target
If .Row > 1 Then
If IsNumeric(Cells(.Row, 1)) = False Then
MsgBox "Not a valid integer value", vbInformation
End If
End If
End With
End Sub

Isn’t it interesting?

I am not allowed to attach excel files in my posts or else I could have provided you the sample macro for this. Please leave your valuable comment here.
