TSV
CSV with a tab instead of a comma — built for shells.
Where it came from
Tab-separated values are CSV's quieter sibling. When Unix tools like awk, cut and sort needed a column format, the tab was the natural delimiter: it never appears inside text, so there is nothing to escape.
That single property made TSV the lingua franca of data plumbing — paste, join, and every shell pipeline speak it natively. Spreadsheets import it too; Excel just calls it "Text (tab-delimited)".
How it works
Mechanically TSV is CSV with delimiter "\t". The killer advantage: a tab almost never shows up in real data, so you drop the entire quoting machinery — no doubled quotes, no escaping rules.
The downside is human eyes: tabs are invisible, so misaligned columns are maddening to debug by hand. UWC converts TSV ↔ CSV (re-introducing quotes) and TSV → Markdown tables losslessly, entirely client-side.
