What is JSONPath?
JSONPath is a query language for JSON, similar to XPath for XML. It lets you extract specific values from a JSON structure using path expressions like $.users[0].name or $..email.
What is in the extraction fixture pack?
The pack includes the reviewed JSONPath, expected match count, expected JSON result types, setup notes, and a starter jsonpath-plus Node test. It intentionally omits raw matched values so you can add a reviewed fixture.json in your own project.
Is my data sent to a server?
No — all processing happens in your browser. Your JSON and query results never leave your machine.
