You must copy the macro in a module of the workbook that you send.

Here is a example for making the font of the range bold in each sheet in the array.

See David McRitchie's site if you just started with VBA


Sub test()
Dim sh As Worksheet
Application.ScreenUpdating = False
For Each sh In Sheets(Array("Sheet1", "Sheet2"))
sh.Select
sh.Range("a1:c10").Font.Bold = True
Next
Sheets(1).Select
Application.ScreenUpdating = False
End Sub

Ron,

can you better explain how to use the array function, I'm not familiar with it.

The workbooks have to be distributed to other people, would it work on their PC if I put the macros on my personal.xls?

Thank you
Alex

Hi Metallo

You can use a array if you know the names of the 10 sheets
For Each sh In Sheets(Array("Sheet1", "Sheet3"))
Then, I have a second question,
You can store the macro in your personal.xls file but for only 10 workbooks
I think I add the macro to each workbook

Hi,

I have a workbook that contains 15 worksheets and I want to create 2 macros that apply a different formatting to 10 of the
worksheets only.
I created 2 buttons in a Macro sheet added to the WorkBook and when I have clicked the buttons they do apply the formatting to
all
the 15 worksheets plus the macro sheet as well.
I presume this is due to the fact that I recorder the macro to be applied to this specific workbook, but I cannot find a
possibility to apply it only to specific worksheets.

Then, I have a second question, what's the best way to apply the same macro to 10 additional workbooks who only differ from
the
one described because have different values?

Thank you
Alex
