Zonino,

You're going to have to provide a bit more information.

You want to pull GL descriptions matching your GL codes from some file somewhere. Where?? If it can't be in another Excel workbook for which you can use a lookup function, and it can't be in the same workbook you're using, where are those descriptions stored? Text file (.csv, .txt, etc.)? On a piece of paper in the file cabinet next to you?

If you don't have access to the list of descriptions, Excel certainly won't have access to it either.
