AVAILABLE FOR WEB, FLUTTER & QA PROJECTS
How to use this tool
1. Paste JSON Payload or Choose Preset
Enter your JSON data into the editor or pick a preset (E-Commerce Catalog, GitHub User API, OpenAI Chat Completion Payload).
2. Write or Select JSONPath Query
Type a JSONPath expression (e.g. $.store.book[*].author, $..price, or $.items[?(@.inStock == true)]) or click an example shortcut.
3. Inspect Extracted Results & Matches
View instant query execution stats, the total number of matched nodes, and the formatted extracted JSON value or array.
4. Copy Result or Path Expression
Copy the extracted data or query expression to your clipboard for use in Postman test scripts, Playwright assertions, or backend code.
Formula or logic used
JSONPath Query Syntax & Evaluation Standards
Evaluates JSON structures using the standardized JSONPath grammar specification (RFC 9535 / Goessner specification).
$ : Root object or array identifier; all JSONPath expressions start with $. or [] : Child property accessor (e.g. $.store.book or $['store']['book']).. : Recursive descent operator; searches for matching property names across all nested levels (e.g. $..author)* : Wildcard matching all elements or properties (e.g. $.store.book[*])[start:end:step] : Array slicing operator for indexed collections (e.g. $..book[0:2])[?(@.expr)] : Filter expression evaluating a condition on the current object @ (e.g. $[?(@.price < 20)])
Examples
Example 1: Extract All Authors from Nested Store Catalog
Traverses the book array and extracts the author field from every item.
Example 2: Recursive Price Filter (< $15.00)
Finds all books with a price lower than 15 regardless of nesting depth.
Common use cases
API Testing & Postman Assertions
Draft and test JSONPath expressions to validate API response payloads in Postman and Newman test suites.
Playwright & Cypress API Mocking
Extract targeted JSON nodes for end-to-end testing assertions without complex lodash manipulations.
Data Pipelines & ETL Transformation
Configure path extraction rules for Apache Camel, Kafka Connect, or AWS EventBridge event filtering.
Debugging Webhook & Third-Party Payloads
Isolate specific event attributes from massive Stripe, GitHub, or Shopify webhook bodies.

Frequently asked questions
What is JSONPath?
JSONPath is an expression language for querying and extracting specific elements, arrays, and properties from JSON documents, functioning similarly to XPath for XML documents.
What does the recursive descent operator (..) do?
The `..` operator searches recursively through all child objects and arrays at any depth. For example, `$..name` will find every property named `name` anywhere inside the entire JSON document.
Can I use JSONPath in Playwright or Selenium tests?
Yes! While Playwright natively parses JSON with JavaScript, JSONPath is heavily used in API testing libraries, Newman, RestAssured, and cucumber step definitions to assert against response payloads.
How do filter expressions [?(@.condition)] work?
The `@` symbol represents the current item in the array or collection being evaluated. The filter checks the boolean condition for each item, returning only those items where the expression evaluates to true.
