What is JSONPath used for?

Extracting specific values or elements from a JSON document using a path-based query syntax, similar in spirit to XPath for XML.

Does it show matches live as I type the expression?

Yes, matches update as you refine the expression, letting you iterate quickly instead of running the query repeatedly to check results.

Can I test complex expressions with filters and wildcards?

Yes, standard JSONPath features including filters, wildcards and array slicing are supported.

Does JSONPath Tester upload my files to a server?

No. JSONPath Tester runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

Writing a JSONPath expression to extract specific data from a JSON document takes trial and error, and testing it against real data as you write it is much faster than writing blind and hoping the syntax is right. This tool tests JSONPath expressions against JSON data and shows the matches live, letting you iterate on the expression until it selects exactly what you need.
