TSV

How it opens

TSV parses into the records shape — many rows of the same shape, browsed as a list with a per-row view.

Nothing is chosen by file extension alone: every adapter scores the text itself and the highest confidence wins. When two are close enough that guessing would be a coin flip, the app asks instead of picking.

• —extensions · .tsv, .tab
• —media type · text/tab-separated-values
• —shape · records
• —extra diagnostics · this adapter lints beyond what parsing reports

Fixing

A broken TSV document gets a verdict — “Not valid TSV yet · N fixable” — and a list: every problem on its line, with the fix’s name, before anything changes. Fix all rewrites only the lines it names and leaves every other byte as pasted; ⌘Z puts the original back exactly. Typing a fix yourself counts the verdict down with no click.

Nesting

A TSV value can hold another system's output — a stringified body, an escaped document. Unpack opens it in place, names the parser that opened it, and repeats until nothing parses. Pack restores the original text byte for byte rather than re-serializing from the tree.
