JSONPath Tester

Test common JSONPath expressions against JSON locally in your browser. Use it to inspect API responses, fixtures, logs, and documentation examples without uploading data.

Paste JSON and run a JSONPath expression when you are ready.

How to use it

What this JSONPath Tester is for

Use this JSONPath Tester when you need to inspect API responses, nested fixtures, log payloads, or documentation examples quickly.

It is useful for checking whether a path returns the expected fields before writing tests, examples, validation rules, or transformation code.

Supported JSONPath examples

The MVP supports the most common JSONPath selectors:

  • $ for the root document
  • $.users[0].name for a nested property on an array item
  • $.users[*].id for all IDs in an array
  • $..name for recursive lookup of every name property
  • $['meta']['count'] for bracket property access
  • $.users[*].roles[*] for nested array values

Filters such as $..users[?(@.active)], slices such as [0:2], and unions such as [0,1] are not supported in this first version.

Use the JSON Formatter to validate or clean input first, the JSON Pointer Resolver when you need one exact RFC 6901 location, the JSON Schema Generator when you need a validation draft, and the JSON to TypeScript Types Generator when you need types from the same JSON payload.

FAQ

JSONPath Tester questions

Does this JSONPath Tester upload my JSON?

No. JSON parsing and JSONPath evaluation run locally in your browser, and the tool does not send your input to a server.

Which JSONPath syntax is supported?

The first version supports common selectors such as $, .property, ['property'], [0], [*], .*, and recursive property lookup with ..property.

Are JSONPath filters and slices supported?

Not yet. Filters, slices, and unions are intentionally excluded from the MVP so the tool can stay lightweight and dependency-free.

What is the difference between JSONPath and JSON Pointer?

JSONPath is a query-style syntax that can return multiple values. JSON Pointer identifies a specific location with a slash-delimited path.
