I could knock out he concatenation formulas pretty quickly, they're not too complicated. For the de-concatenation, are they like the examples attached? Are there dashes between every item, or do they need to be pulled out of a complete text string.
I also will state up front that I don't have experience with Access, but I do understand databases. Do you just need a spreadsheet setup in a way so that it can be pulled in Access easily? Or do you need specific Access queries written?
Thanks! :)
