How to use JSONPath Tester

Query JSON with a JSONPath expression.

  1. Paste the JSON document you want to query.
  2. Type a JSONPath such as $.store.book[0].title into the JSONPath field.
  3. Press Run and read every value the path matches.

Practical note. JSONPath uses $ as the root — try $.store.book[0].title to test an expression. The tester highlights every match in the document tree.

When you actually reach for this

  • You need to query a specific field out of a large JSON document without writing a full parser.
  • You are building a filter or extractor and want to confirm a JSONPath expression before hard-coding it.

Where this tool stops being accurate

  • JSONPath has no single official spec; engines differ on filters, slices, and wildcard behavior, so test against your actual library.
  • Complex recursive descent ($..) on big documents can be slow and return far more than you expect.

Frequently asked questions

What does JSONPath Tester do?

Query JSON with a JSONPath expression.

My JSONPath returns nothing but the data is there — why?

Usually a syntax mismatch with your engine (e.g. filter brackets or quoted keys) or a wrong root. Try a simpler path first, then add the filter.

Is JSONPath the same as XPath?

No — it is inspired by XPath but for JSON, and each implementation varies. Do not assume a path that works in one tool works in another.
