Maybe you could just copy the whole thing. Wouldn't that be the same as
comparing?
If desired, send your file to my address below. I will only look if:
1. You send a copy of this message on an inserted sheet
2. You give me the newsgroup and the subject line
3. You send a clear explanation of what you want
4. You send before/after examples and expected results.

Hi

In Excel 2003 I have a spreadsheet listing a large number of cost centres.
Each month I am given a list of the cost centres and expenditure against
them, which I want to use a look up to populate in to a master
spreadsheet.
However, during the month new cost centres could have been created.

What I would like to be able to do is run a macro against the monthly
return
and compare the codes contained in it to the codes already listed in the
master sheet. If there are any new codes not already in the master sheet
I
would want them added to the existing list so that the master remains
complete. Any suggestions on how to achieve this would be welcomed.
