JSON Path Tester
Enter JSON and a JSONPath expression to inspect matching values. Results are calculated locally in your browser.
About JSON Path Tester
Test JSONPath expressions against real JSON with this free online JSONPath tester and see matching values instantly. It supports field access, array indexes, wildcards, slices, and recursive descent, so you can build and debug a query before wiring it into code, a gateway, or an automation tool. Handy for API testing, data extraction, CI assertions, and message mapping.
JSONPath is how many tools pick a nested field without writing a full parser. Getting the expression wrong means empty results in production. This tester lets you iterate on $.store.book[*].author style queries against a sample document until the matches look right. Developers, QA, and integration engineers use it to extract lists, optional fields, and deep properties from API payloads.
Paste JSON, type a JSONPath, and read the matches. Adjust wildcards and slices without leaving the page. If the document is invalid JSON, fix that first. If the path is legal but matches nothing, you see an empty result instead of a crash, which is the same signal your pipeline would get. Copy a working expression into code or a config file.
Everything is evaluated locally in your browser, keeping your JSON private. Use this free JSONPath tester and JSONPath evaluator whenever you need to prototype a query against real nested JSON with no upload.
