Quick Version:
I've changed the format on a column of numbers, text and number-text
combinations to text format in order to make it match another file I'm
comparing with. The comparison is not finding ANY matches right away. I can
go back and double click in a cell (as if to edit it) and then press the
enter key and VIOLA! the match appears. It is almost as if I'm having to
finalize EACH INDIVIDUAL cell to make it work, which will not be effiecient,
as I've got 8,000 cells to click on.

QUESTION:
Is there a way to "finalize" this format change globally without having to
click on each cell?

Details:
We receive a LARGE price sheet (DOC A) from our vendor periodically. The
part number column is formatted as text. There are some alphanumeric values
in the column, but the majority are in this format: 12345.60.

I export a CSV document from my product database with the current pricing
(DOC B) and want to compare this document with the one from our vendor, among
others also in text format. When I open this CSV document, I format the part
number column to text to match the others.

The formula that I use on DOC A (Vendor sheet) looks at DOC B (our current
pricing) for the part number. If there is a match, then it dispays the
retail price in this column where my formula is. If there is not a match, it
dispays "Add To Site".

My formula is:
=IF(A376="","",IF(ISNA(MATCH(A376,Source!A:A,0))," Add To
Site",VLOOKUP(A376,Source!A:B,2,0)))

90% of the columns show "Add to Site" even though we have 90% of the items
on our site. I can go to the sheet that I manually formatted to text, double
click in one of the cells containing the part number, press my enter key and
then the match shows up on our vendor sheet instantly.
