AFAIK this has to be done with a macro. To avoid problems with ranges I
create Range names Old_Labels, New_Labels and Labels on the sheet you want
to update. Copy the code into a VB Module, ALT + F8, Insert Module and Paste
the code into the module. Return to the workbook and run the code. ALT + F8,
select code and click Run.

Sub test()
Set rng = Range("Labels")
Set rngOld = Range("Old_Labels")
Set rngNew = Range("New_Labels")

For Each c In rng
x = WorksheetFunction.Match(c, rngOld, 0)
If IsError(x) Then
'do nothing
Else
c.Value = WorksheetFunction.Index(rngNew, WorksheetFunction.Match(c,
rngOld, 0))
End If
Next
End Sub

I'm sure this can be done so pls assist...

I have to worksheets.

The first one has two columns: Old Label and New Label.

The 2nd worksheet has several columns and i want to do a search in a
specific column (column O). The search should be the text in the other sheet
(Old Label) and all matches should be replaced with the New Label.

Please help!
