I have a working file with more than 50 sheets. When I send out to my users I
would like to hide both the row and columns headers in every sheets. Can
someone help?

I am using the below to copy and paste values in every sheet and it worked
very well. Not sure if some coding can be added inside the loop.

Set WB = ActiveWorkbook
For Each SH In WB.Worksheets
With SH.UsedRange
.Value = .Value
End With
Next SH
