How to automatically protect all worksheets when closing an Excel workbook?

Author Siluvia Last modified

Normally, you can manually protect a worksheet or the whole workbook by password with the Protect Sheet or Protect Workbook feature in Excel. But if you want to protect all worksheets automatically with password upon workbook closing, what can you do? This article will show you a VBA method to achieve it.

Protect all worksheets when closing the Excel workbook with VBA code

To automatically protect all worksheets when closing a workbook, please apply the following VBA code.

1. In the workbook you want to protect all worksheets when closing the file, please press the Alt + F11 keys to open the Microsoft Visual Basic for Applications window.

2. In the Microsoft Visual Basic for Applications window, double-click the ThisWorkbook in the left pane, and then copy below VBA code into the Code window. See screenshot:

VBA code: Protect all worksheets when closing the workbook

Private Sub Workbook_BeforeClose(Cancel As Boolean)
'Update by Extendoffice 2018/1/24
    Dim xSheet As Worksheet
    Dim xPsw As String
    xPsw = ""
    For Each xSheet In Worksheets
        xSheet.Protect xPsw
    Next
End Sub

Tips:

1) In the code, please specify your password in the line xPsw = “”.
2) If you only want to protect a specific worksheet automatically when closing the workbook, use the VBA code below.
Private Sub Workbook_BeforeClose(Cancel As Boolean)
    Sheets("Sheet1").Protect "123"
    ActiveWorkbook.Save
End Sub

3. Then press the Alt + Q keys to close the Microsoft Visual Basic for Applications window.

After the above step, all worksheets or specified worksheet will be protected automatically when closing the workbook.

Notes:

1. You must save the workbook as Excel Macro-Enabled Workbook file format.
2. Please go to the certain worksheet, click Review > Unprotect Sheet. And then type in the password you specified in the VBA code to unprotect this worksheet.
