Paste JSON, YAML, or CSV, write a jq filter, and see results update live. This runs the real jq engine right in your browser — nothing is uploaded. Explore the cheat sheet, load an example, chart your results, or share a link.
1. Put your data in the Input panel. Leave the format on Auto (detects JSON or YAML) or pick CSV/TSV/YAML explicitly.
2. Type a jq filter in the Filter box, e.g. .users | map(.name). Results update as you type.
3. Use the option chips for jq flags: -c compact, -r raw strings, -s slurp inputs into one array, -n null input, -S sort keys.
4. Switch the Output panel to the Chart tab to visualize arrays of numbers or objects. Set output format to YAML to get YAML back.
