Replace name of workbook in macro to active workbook

I want to Replace the name of that excel sheet which is selected to be active workbook and make macro from any workbook

It's a little confusing exactly what you want - are you saying you don't want to select the workbook that is highlighted and instead want the macro to run on the currently active workbook?

If so, why not just delete the line?

as i am beginner in macros i really dont konw what i put instead of the selected workbook to make macro run on any active workbook
