Hi Dana,
One way:
Sub DeleteApostrophes()
Dim rCell As Range
Dim Rng As Range
Set Rng = ActiveSheet.UsedRange '<<=== CHANGE
For Each rCell In Rng
If rCell.PrefixCharacter = "'" Then
rCell.Value = rCell.Value
End If
Next rCell
End Sub
If you do not wish the procedure to operate on the whole sheet. you should
set Rng to an appropriately restricted range.
