Half of marketing work is getting data out of a spreadsheet and into a tool that wants a plain list, then back again. The tab is what makes that transfer awkward.
The forward direction
Copy a row of forty campaign names, convert tabs to lines, and you have a list ready for whatever needs one per row. No intermediate file, no export dialog, no CSV settings to negotiate.
The return trip
Once the list has been sorted, filtered or deduplicated, joining it back into a tab-separated string pastes cleanly back across a spreadsheet row.
The habit worth forming
Treat the spreadsheet as storage and the list tools as the working surface. Trying to do list manipulation inside a spreadsheet means writing formulas for operations that are a single click elsewhere, and formulas are where subtle errors live.
