For confidentiality reasons in Excel, users are usually not expected to view and modify formulas. You can take advantage of Excel’s Lock, Hide, and Protect Worksheet features to hide and lock formulas. However, it will be more troublesome to set according to the conventional method, but using Excel’s macro, add a “protect formula” button on the toolbar. When you need to hide and lock the formula, you can complete the protection with a single click.

In order for this macro to work for all workbooks, it needs to be saved to a “Personal Macro Workbook”.

Step 1: Execute the “Tools→Macro→Record New Macro” command to open the “Record New Macro” dialog box.

Step 2: Click the “Save in” drop-down button on the right, and in the drop-down list that appears, select the “Personal Macro Workbook” option to enter the recording state.

ActiveWorkbook.SaveAs Filename:=z & “\” & y & “.xls”


ActiveWorkbook.SaveAs Filename:=ActiveWorkbook.Path & “\” & ActiveWorkbook.Name

End If
