I wanted to do this with a sql query, but I am a relative beginner at
vba/excel. Also, the IT department's backlog is pretty long, so I can't
get the proper command lines from them. Instead, I keyed off vlookup
and its associated errors. #Value indicates a match. I have already
proven that with many runs of my macro. It just takes forever!

I am working on a macro to compare two lists of job numbers in two
separate workbooks. If there are any matches, those duplicate jobs are
flagged. I used vlookup to accomplish this. My problem is that my
table_array could have as many as 10000 cells. When I use vlookup to
check 200 different lookup_values, the processing time is, to say the
least, massive.

Is there any way to speed up this process? I had thought of sorting the

table_array, since there are a lot of blank cells in it. I guess my
main question is, how would I have one workbook sort a column in
another workbook?


Any help would be appreciated.

Please post your code so we can look at it and offer suggestions. One
thing i can say right now though is to investivge
application.screenupdating = false
