Also searched as query, jsonpath, path, select, extract, filter, evaluate, jsonpath tester.
Compile the path expression
Traverse typed nodes in WASM

JSONPath Query FAQ
Which expressions are supported?
The current leg supports common JSONPath navigation and filters plus a deliberately small jq-compatible selection syntax.
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.
