严格使用Excel打开.xlsm

Question

I want my macro enabled .xlsm file, to be opened using Excel only.

Can I know & deny other applications trying to open it?

Private Sub Workbook_Open()
...
End Sub

Answer 1

You may be able to deny it on your own machine through your OS's setup; however since it's the OS that's doing the "Opening" you have little to no control over someone else's machine. Your best bet would be to password protect the workbook via: file>save as>computer>browse>tools>general options.
