JSON Path Finder

JSONPath is a query syntax for navigating JSON data structures, analogous to XPath for XML. When working with complex API responses, configuration files, or data dumps, finding the exact path to a deeply nested value is tedious. JSONPath provides a standardized way to express these locations.

Developers use JSONPath in API testing tools like Postman, data transformation pipelines, log analysis, and configuration management. Knowing the exact path to a value lets you write precise extraction logic in any programming language.

The root element is always $ (dollar sign). Object properties are accessed with dot notation: $.store.name. Array elements use bracket notation: $.store.books[0]. The wildcard [*] matches all array elements: $.store.books[*].title returns every book's title.

More advanced JSONPath implementations support recursive descent (..), filter expressions ([?(@.price < 10)]), and script expressions. This tool focuses on the core syntax — root, property access, indexing, and wildcards — which covers the vast majority of real-world use cases.

Visualizing JSON as a tree makes it much easier to understand nested structures. Each node in the tree shows its path, type, and value. Objects are shown with their property count, arrays with their length. Primitive values (strings, numbers, booleans, null) are displayed inline.

The tree view in this tool is fully interactive — click any node to copy its path. Combined with the search filter, you can quickly locate any value in even deeply nested JSON structures.

API development: Find the exact path to extract from a complex API response. Data migration: Map paths between different JSON schemas. Debugging: Locate where a specific value lives in a configuration file. Testing: Write JSONPath assertions in API test suites.

The path finder is also valuable for documentation — showing consumers of your API the exact paths to the data they need, complete with types and example values.
