JSONPath Tester
Test JSONPath expressions against sample JSON locally in your browser and inspect matched paths, values, and dialect boundaries.
Paste a JSON document and a JSONPath expression to check which values match before using the query in docs, API debugging, data extraction notes, or test fixtures. Processing stays browser-local and the supported dialect is listed in the result.

JSONPath Tester
How to use
Finish in three steps
- 01
Paste a valid JSON object or array into the JSON field.
- 02
Enter a JSONPath expression using the documented browser-local dialect.
- 03
Click Test JSONPath and review the matched paths, values, and match count.
- 04
Copy the result only after confirming the target library uses compatible JSONPath semantics.
Supported dialect
The tester supports $, .name, ['name'], [0], [*], ..name, ..*, and simple filters in the form ?(@.field == value), !=, >, >=, <, or <=. Filter values may be strings, numbers, booleans, or null.
Browser-local sample testing
The JSON document and query are evaluated in the browser. The tool does not upload sample data, call external APIs, fetch URLs, or store query history.
Compatibility boundaries
JSONPath implementations vary. This tester does not support script expressions, functions, slices, unions, parent operators, or custom library extensions, so final queries should be checked in the production library.
FAQ
About this tool
Which JSONPath features are supported?
Use root $, dot and bracket property access, array indexes, wildcards, recursive descent, and simple comparison filters.
Can I run script filters or functions?
No. The tester intentionally does not execute scripts, functions, eval-style expressions, or custom callbacks.
Is pasted JSON uploaded?
No. Evaluation is browser-local and does not send the JSON or expression to an external service.
Why does another JSONPath library return different results?
JSONPath dialects differ. Check whether the other library supports slices, unions, strict comparisons, recursive descent, or filter syntax differently.
