I want to generate in a cell a GUID for the excel file. However, it cannot change every time you open/ close it. It would be a once and done deal. So re opening it to make some edits, keeps the GUID the same.
It has to do with SSIS package I built, and in order for the DB to update the already imported fields, I need something unique that won't change each time you open the file up on the client side.
