how can I cross reference 1 excel spreadsheet against another

[SusieMuir]

Please help!
I have a very simple database of names & addresses on 1 excel spreadsheet
and I want to cross reference them against another. I sthere a quick way of
doing this?

Maybe using =vlookup() or =index(match()).

You may want to read Debra Dalgleish's notes:
http://www.contextures.com/xlFunctions02.html (for =vlookup())
and
http://www.contextures.com/xlFunctions03.html (for =index(match()))

Using an unique identifier between the two, look in Excel help at

Vlookup

or if the identifier is no in the left most column of the data of interest
then look at

=Index(Othersheet!column1,match(identifier,OtherSheet!column3,0),1)

where the pseudo references would need to be replaced by the actual range
references.
