I have two different files, both use the same unique identifiers. How can I
ascertain which records are missing from the smaller file.

For example:

File A, has 28,225 different records.
File B, has 14,205 different records.

Which records from File A, are missing from File B?

Thank you, Jerry

Hi,
if you apply a vlookup then everything that shows as #N/A means that are
missing from the other list

Let' say your File A is in sheet1 and File B in sheet2 starting in cell A2,
in B2 sheet1 enter

=VLOOKUP(A2,Sheet2!A1:A25000,1,FALSE)

Eduardo, than you for your quick reply. I would have responded sooner I have
been having a hard time trying to make your solution work, and was
unsuccessful -all, came back "#N/A". I must be doing something wrong. Could
you please elaborate, I am not an Excel power user.

Thanks.

.. and was unsuccessful -a lot of false "True" ..
You're probably hit by data inconsistency, either text nums vs real nums
issue and/or extraneous white spaces for textstring matches. It's quite
common. Paste some representative sample data for both the lookup values and
the reference col values where there are apparent matches which are not being
returned correctly.
