JSON Path Tester

Test JSONPath expressions against JSON data — extract nested values, arrays, and filtered results instantly.

About JSONPath

JSONPath is a query language for JSON, similar to XPath for XML. It allows you to select and extract specific parts of a JSON document using a path expression syntax. JSONPath is widely used in REST API testing tools like Postman and REST Assured, JSON processing libraries, data transformation pipelines, and configuration management tools.

Key JSONPath operators include: $ (root), . (child), [] (subscript/array index), * (wildcard for all children), .. (recursive descent to find keys at any depth), [start:end] (array slicing), and [?(filter)] (filter expressions).

This tester implements the most common JSONPath operators and gives you immediate visual feedback on what your path expression matches, with the result count and formatted output.

Where is JSONPath used in practice?
JSONPath is used in AWS Step Functions for data extraction, Postman test assertions, Kubernetes JSON patches, REST Assured API testing in Java, jq (a similar query tool), and many data transformation pipelines.
