Paste your JSON and a JSONPath expression, and the tool extracts and shows the matching values live.
JSONPath is a query language for JSON, similar to XPath for XML. Developed by Stefan Goessner.
$ represents the root of the JSON document. $.users[0].name gets the first user's name.
$ (root), . (child), [] (subscript), * (wildcard), [?(@.prop)] (filter), .. (recursive descent)
