JSON Path Evaluator
More about the JSON Path Evaluator
A simple dot-notation path like $.store.name handles the easy case, but JSONPath's real power shows up in a filter expression like $.store.book[?(@.price < 10)], selecting only the nodes that match a condition, or a recursive descent operator like $..author, finding every author field no matter how deeply nested it is, syntax that's genuinely harder to get right than a plain property lookup. This tool evaluates JSONPath expressions against real JSON data, handling filter conditions and recursive descent correctly rather than only simple property paths. Useful for testing a filter expression that selects nodes matching a specific condition, confirming a recursive descent query actually finds every matching field at any depth, or debugging a JSONPath expression that returns the wrong nodes before it goes into actual code.
