A simple export of a table as CSV does NOT come back in tact!
I added a period to another text field using Notepad to make the simplest change possible without formatting issues. Then, I imported the same CSV I exported save for the 1 period added within a text string (so it would update the record).
The multiple select column kept only ONE selection for the updated row…
I need to be able to import updated content reliably. This is not proving to be the case.
