About this tool

This is a focused JSONPath evaluator that runs entirely in your browser — nothing is uploaded or executed on a server. It implements a predictable subset of JSONPath rather than the full spec, so filters and script expressions are not supported. Use it to quickly check which values a path selects before wiring it into code.
