Runs entirely in your browser

Live evaluation

Every keystroke re-runs the expression. Sub-millisecond feedback, with a timing readout.

Matched paths panel

See every path that matched — copy any one to navigate to it in the editor.

Snippet library

Common patterns prewired: $..*, $..[?(@.active==true)], $..*[0:3]. One click to insert.

Privacy-first

Powered by jsonpath-plus, running in your browser. Your JSON never leaves the page.

FAQ

Which JSONPath dialect does this use?
The jsonpath-plus implementation, which extends the original Goessner spec with parent (^), property (~), and script filters.
Can I save my expressions?
The current expression is persisted to localStorage automatically. Reload the tab — it's still there.
What about jq or JSONata?
jq is now available — pick the jq tab in the Query view to run real jq 1.8 (WebAssembly) right in your browser, fully local. JSONata is still on the roadmap.
