FAQ

Which JSONPath implementation is used?

jsonpath-plus, a widely used JavaScript implementation, with filter expressions evaluated by a sandboxed interpreter (no eval).

What is the difference between JSONPath and JSON Pointer?

JSON Pointer (/store/book/0) addresses exactly one value. JSONPath is a query language that can match many values using wildcards and filters.

Is my data uploaded anywhere?

No. This tool runs entirely in your browser. Your input never leaves your device, is not logged, and works offline once the page has loaded.
