This engine follows a Goessner-style subset (goessner.net/articles/JsonPath). Not every feature from Jayway, kubectl, or Postman dialects is available.

Supported

  • Root $
  • Dot notation .key

  • Wildcards * on objects and arrays
  • Recursive descent ..
  • Array indexes and filters [?(@…)] on arrays

JSONPath Tester Online

Write and test JSONPath expressions against sample or real JSON instantly. Wildcards, recursive descent (..), array slices, and filter expressions all run live with matches highlighted on the source JSON. Useful for debugging APIs, extracting values, and validating selectors before production use.

Frequently Asked Questions

Is this tool free?

Yes. The JSONPath tester is free with no sign-up required.

Is my JSON uploaded?

No. Parsing and matching run in your browser; your data does not leave your device for this tool.

What is JSONPath?

JSONPath is a way to point at parts of a JSON document—like paths, array indexes, wildcards, and filters. See also What is JSONPath?.

Does it support wildcards?

Yes, within this site's documented subset—use * for arrays and objects and combine with dot paths and filters.

Why are there no matches?

Often the keys or indexes in your expression do not match the JSON. Confirm names and nesting with the JSON Formatter, then try a simpler path and build up.

Can I test nested arrays?

Yes. Use chained segments like $.items[0].tags[*], slices, and filters on arrays.

Does it work on mobile?

Yes. Panels stack vertically, the Run action stays easy to reach, and extra actions live in a bottom sheet.

Can I copy results?

Yes. Copy all matches as JSON from the actions menu, or copy a single value from each result row.
