How to make a particular cell mandatory enter before closing workbook?

Author Sun Last modified

When you share a workbook to other users for doing a survey which needs the real name registration, for instance, every user under investigation needs to enter their name in B1. But in some times, some users may close the workbook after investigation without entering their names. In this article, I introduce a VBA to make a particular cell mandatory before closing the workbook.

1. Enable the workbook that contains the mandatory cell, and press Alt + F11 keys to open Microsoft Visual Basic for Applications window.

2. In the Project pane, double click ThisWorkbook, and go to select Workbook and BeforeClose from right section list, then paste below code to the script. See screenshot:

VBA: Make a cell mandatory

    If Cells(1, 2).Value = "" Then
        MsgBox "Cell B1 requires user input", vbInformation, "Kutools for Excel"
        Cancel = True
    End If

3. Then save this code and close this popping window. Now, if the cell B1 is blank when you close the workbook, below dialog will pop out to remind you to enter something in B1. See screenshot:

Tip: You can change cell B1 to other cells you want.
