How to use JSONPath Tester

Paste a JSON document into the input panel and type a JSONPath expression into the query field. Results matching the expression are highlighted in the document and listed in the output panel, making it easy to iterate on complex path queries.

Common use cases

Backend developers use this to extract specific fields from deeply nested API responses during integration work. QA teams use it to write precise assertions for API test suites, and data engineers use it to prototype JSONPath queries before embedding them in transformation pipelines.

Why run this in your browser?

All processing happens locally in your browser. Your data never leaves your machine, making it safe for sensitive payloads, internal API responses, and confidential configurations.
