A spreadsheet column pastes in as newline-separated. The script you’re feeding it into wants one comma-separated line. Reformatting that by hand is exactly the kind of chore a browser tab should handle for you.
Our new list converter:
- Auto-detects your input — newlines take priority; if there are none, it tries commas, then semicolons.
- Four output formats — comma, semicolon, newline, or pipe.
- Trim and clean — strip surrounding whitespace and drop empty items (the double-comma-in-a-spreadsheet problem), both on by default.
- Quote-wrap for code — turn a plain list into
"item", "item"ready to paste into an array literal or a SQLIN (...)clause.
It’s a simple delimiter splitter, not a full CSV parser — it won’t untangle quoted fields with commas inside them, and the tool says so plainly. For that, and for deduping, pair it with our duplicate-line-remover.
Your six formatting options sync to the URL for a shareable pre-configured link; the list content itself never does.
