How to run Excel macro on file opening

Here is how to run Excel macro automatically every time you open the file in a few easy steps.

1. When you are in Excel file press Alt + F11 to open VBA window.

2. In the Project section, locate your file and open ThisWorkbook section.

3. You should make subroutine with Workbook_Open event that contains the name of your macro.

Private Sub Workbook_Open()

'Here goes your macro or name of your macro.

End Sub

ThisWorkbook.Saved = True

Application.Quit
