What is the JSONPath Tester?
The free JSONPath Tester lets you run JSONPath queries against any JSON document and see the matching results instantly. Paste your JSON into the JSON Data textarea, type a JSONPath expression into the Expression input — like $.store.books[*].title — and the matching values appear in the Results panel with a count. Six quick example chips demonstrate the most useful path patterns so you can learn by example or get started without writing a query from scratch.
- → Extract specific fields from large, deeply-nested API JSON responses
- → Test JSONPath expressions before embedding them in code (Python jsonpath-ng, JS jsonpath-plus)
- → Query specific array elements or object properties from config or data files
- → Learn JSONPath syntax by experimenting with the built-in example chips
- → Debug data transformation pipelines that use JSONPath-based field extraction

Frequently Asked Questions about the JSONPath Tester
- What is the JSONPath Tester?
- The JSONPath Tester is a free online tool that lets you test JSONPath expressions against JSON data and see matching results. It runs entirely in your browser, so there is nothing to install and nothing is uploaded to a server.
- Is the JSONPath Tester free?
- Yes — the JSONPath Tester is completely free, with no account, subscription, signup, or usage limits.
- Is my data uploaded or stored?
- No. The JSONPath Tester processes everything locally in your browser. Your input is never uploaded, saved, or shared with any server.
- Does the JSONPath Tester work offline?
- Yes. Once the page has finished loading, the JSONPath Tester works without an internet connection.
- Which browsers does the JSONPath Tester work in?
- The JSONPath Tester works in all modern browsers, including Chrome, Firefox, Safari, and Edge — no plugins or extensions needed.
- What JSONPath operators does this tool support?
- The tool supports: $ (root), . (dot-notation child), .. (recursive descent — search at any depth), * (wildcard — all children), [n] (array index), [-n] (negative index from end), [n:m] (array slice), and ['key'] (bracket notation). Filter expressions (?(expression)) are not currently supported.
- What is the difference between . and .. in JSONPath?
- . is the standard child operator — $.store.name navigates one level at a time. .. is the recursive descent operator — $..price searches for a "price" key at any depth throughout the entire document. Use .. when you don't know how deep the field is nested.
- Can I use negative array indices like [-1]?
- Yes. [-1] selects the last element of an array, [-2] the second-to-last, and so on. Click the "Last book" quick example chip to see it in action with the built-in sample JSON.
