JSONPath Tester

JSONPath is a query language for JSON, similar to XPath for XML. You use it to extract specific values from nested JSON structures — for example, pulling all order IDs from an array of orders, or grabbing every email address nested under customer objects. It is widely used in REST API testing tools like Postman, AWS Step Functions, Kubernetes manifests, and monitoring configurations.

The $ symbol always refers to the root of your JSON document. Every JSONPath expression should start with $. From there you use dot notation ($.store.name) to navigate object keys, bracket notation ($.orders[0]) to access array elements, and wildcards ($.orders[*]) to match all items in an array or all values in an object.

$.key navigates directly to a property at one specific level of the JSON tree. $..key uses recursive descent, meaning it searches at every depth — it will find 'name' whether it is at the top level, inside an array, or nested five levels deep. Use .. when you want to extract a field without knowing exactly how deeply it is nested.

Use the wildcard operator: $.orders[*] selects every element in the orders array. You can chain this with further selectors — for example $.orders[*].id returns the id property from every order object in the array. To select a specific index use $.orders[0] for the first, $.orders[-1] for the last.

Yes, using filter expressions: $.orders[?(@.price > 100)] selects all orders where price is greater than 100. The @ symbol refers to the current element being tested. You can use comparison operators (>, <, ==, !=), logical operators (&&, ||), and string matching to build precise filters.

Yes. The JSONPath Tester runs entirely in your browser using JavaScript. No data is transmitted to any server. Your JSON payload — including API responses, config files, and any sensitive values — never leaves your machine. It is safe to paste production API responses for debugging.
