JSON Path Tester
Test JSON Path expressions. Query and filter JSON data with path syntax.
About JSON Path Tester
Test JSONPath expressions against any JSON document. Enter a JSONPath query (e.g., $.users[*].email) and see all matched values highlighted in the JSON. Supports dot notation, bracket notation, recursive descent (..), array slices, filter expressions, and wildcard selectors. Useful for writing JSONPath queries for APIs, XSLT alternatives, and data extraction scripts.
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local and private. Free to use forever.
Common use cases
- Extracting specific fields from deeply nested API JSON responses
- Filtering array elements by field value using JSONPath filter expressions
- Learning JSONPath syntax by testing queries against real JSON
- Writing JSONPath expressions for AWS EventBridge, GCP Pub/Sub, or other event routing
- Querying JSON logs for specific field values
How it works
Parses the JSONPath expression into a sequence of path steps (property access, array index, filter, recursive descent). Each step is evaluated against the current set of matching nodes. Filter expressions (?(@.price > 10)) evaluate a sub-expression against each array element and return only the elements where it is truthy. Results are returned as a JSON array of matched values.
