Use the Workbook_Open event:

Sub Workbook_Open()
MyMacro
End Sub

where MyMacro is the name of the macro you wish to run.
To use, press ALT+F11 and place the macro
in "ThisWorkbook" module.

Hello,

It is possible to run a VBA macro automatically when I
open a workbook
instead of opening the workbook and then run the VBA
macro from the menu
"Tools" "Macro?"
Thanks,

.
