About JSON Path Tester

The JSONPath Tester lets you write a JSONPath expression and immediately see which values it selects from your JSON, so you can build and debug queries without guesswork. It's ideal for extracting fields from deep API responses, configuring integrations, and writing assertions. Evaluation runs locally in your browser against your pasted data. Explore the structure first with the JSON Viewer, or pull every key with the JSON Key Extractor.

Frequently Asked Questions

What is JSONPath used for?

JSONPath is a query language for JSON, similar to XPath for XML. It lets you select specific values or subsets from a document using a compact expression — useful in integrations, testing, and data extraction.

Can I select multiple matches at once?

Yes. Wildcards and filter expressions can match many nodes, and the tester shows the full list of results so you can confirm your query targets exactly what you expect.

Is JSON Path Tester free to use?

Yes. JSON Path Tester is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use JSON Path Tester?

Absolutely. JSON Path Tester runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
