If you have a lot of them to convert you could copy/paste this code to a
general module in your workbook or your Personal.xls file.
Sub NATrapAdd()
Dim myStr As String
Dim Cel As Range
For Each Cel In Selection
If Cel.HasFormula = True Then
If Not Cel.Formula Like "=IF(ISNA*" Then
myStr = Right(Cel.Formula, Len(Cel.Formula) - 1)
Cel.Value = "=IF(ISNA(" & myStr & "),""""," & myStr & ")"
End If
End If
Next
End Sub
Select your range of cells and run the macro to add the ISNA trap to all.
