Hi,
It depends on the size of data for each sheet.
If one workbook is over 10mb then, yes, separate
workbooks is better. If the total of all sheets is less
than 10mb then one workbook is easierto handle.

If you think that the way you are doing things now is too
cumbersome then maybe a userform may be the answer. Send a
dummy workbook (about 1mb) to me and I will evaluate it.
Anything I do is free until I say not.

Question, is it better to open mulitple workbooks or have
one workbook
with multiple worksheets. I will be doing a lot of
computation with
these files/sheets in VBA, and I was wondering which
would be more
efficient.

If "multiple worksheets" is the answer, then how do I get
the info from
the other workbooks to the multiple-sheet workbook? The
only way I can
think of is writing a macro to copy and paste the info
onto a new
worksheet. Is that the only way?

I hope I am making sense.

John
