What jq Playground does

Try a focused jq-style selection subset in the browser using the same local Rust query engine.

Also searched as jq, jq playground, jq online, jq tester, filter, select, pipe, command line json.

Accept property and array selection

Apply equality select filters

Return typed matches and paths

This is not a full jq reimplementation yet. It targets navigation and selection while keeping the engine contract ready for broader execution later.

QUESTIONS, ANSWERED

Does jsontools.me upload my JSON?

No. The document is parsed and processed by json-buf inside a dedicated WebAssembly worker on your device.

Does it work offline?

Yes. After the application shell and engine have loaded once, the installable PWA keeps the tools available without a network connection.
