In Excel… How does one create a character+number THAT ONLY UPDATES WHEN ENTERED and DOES NOT change with F9 or reloading the spreadsheet?
I want to create sort of an inventory number that I can put on my 3D printer filament boxes to identify them quickly.
But I don’t want the inventory number to ever change after the first creation of the numbers/characters.
