JSON Workbench

Paste JSON, YAML, or CSV and validate it on the spot. Format, minify, or sort keys, then convert between all three formats and query nested values by path.

Every byte stays on this page. Parsing, conversion, and queries all run client-side, so nothing is ever uploaded.

Notes

  • CSV parsing follows RFC 4180: quoted fields, embedded commas and newlines, and "" escaped quotes.
  • Converting to CSV requires an array of objects; the header is the union of keys in first-seen order.
  • Path queries accept dotted keys and bracket access, e.g. users[0].name or ["weird key"].value.
