This works well, but is it possible to delete the apostrophes from all sheets
in a workbook?

I had the same problem. They way I solve it was a bit different, but
quick.

Norman Jones offered this earlier this year:
Sub DeleteApostrophes()
Dim rCell As Range
For Each rCell In ActiveSheet.UsedRange
If rCell.PrefixCharacter = "'" Then
rCell.Value = rCell.Value
End If
Next rCell
End Sub

Also very quick
