Find and copy the exact path to any JSON value

Digging through deeply nested JSON to work out how to reference a single value is tedious and error-prone. This JSON path finder renders your data as an explorable tree and, when you click any key or value, gives you the precise path to it, ready to paste into code, a query, or a test assertion.

How it works

Paste your JSON and the tool parses it in your browser, building a collapsible tree of objects and arrays. Selecting a node reveals its path using both dot and bracket notation, so you can copy exactly the accessor your language or query tool expects. All parsing happens locally in JavaScript, so your data never touches a server.

Practical use cases

  • Grab the path to a field buried in a large API response.
  • Write reliable assertions in integration tests.
  • Build a JSONPath or property accessor for config parsing.
  • Explore an unfamiliar payload's structure quickly.

Working with the same JSON in other ways? Pretty-print it with the JSON Formatter, check it for syntax errors using the JSON Validator, or compare two versions with JSON Diff.

Private by design

Because everything runs client-side, your JSON stays on your machine, with no upload, no sign-up, and no logging. The JSON path finder is free and works in every modern browser, including mobile.

Frequently asked questions
