I have 2 documents with 2 columns each. One document is old and one i
new.

They both have columns named "NAME" and "ID"
The documents don't have exactly the same names in them, but mostly do


What I need to do is to see if an ID is missing for a NAME in the ne
document, and if it is missing and if the old document has this ID fo
the given NAME, then put the ID from the old file into the new file.
have to check for all NAMES in the new document.

Any ideas

Hi,
One way would be to use the Vlookup()
If you have your NAME in column A and ID in column B you could use
something like this in a helper column C in the New document:

==IF(ISNA(VLOOKUP(A1,OldDucument!$A$1:$B$10,2,FALSE)),B1,VLOOKUP(A1,OldDocument!$A$1:$B$10,2,FALSE))

Then place the formula in C1 (If Row 1 is where your data starts) and
then paste it down the lenght of your dataset.

This should produce a list of matching Names and ID's from the Old
document.
If the name does not exist in the old document but in the new it will
get you the ID from column B.

Bondi
