compare 2 spreadsheets and automatically populate fields

[monsoonkhan]

i have 2 seperate spreadsheets. i need to know if the codes on one exist on
the other, and if i do find a match, can i automatically populate fields such
as project manager, location etc.

also, how do i delete cells which are a repeat of previous cells?

Maybe you can use =vlookup() or =index(match()) to look for differences.

Debra Dalgleish has lots of notes:

and

And Chip Pearson has lots of techniques for working with duplicates:
