I have a worksheet that has 40K rows of part numbers. As these part numbers
are from different suppliers, they have different formats. We are sending
this information out in Purchase Orders, via EDI, and we receive Error
messages when a non alphanumeric character is included a part number.

Is there a way I can use a macro to look at all of these part numbers, and
perhaps bold the ones that contain one or more non alphanumeric characters? I
have searched high and low, but have not run across a solution to this
(obviously).
