JSONPath Tester

Test JSONPath expressions online

JSONPath is to JSON what XPath is to XML: a compact query language for selecting values out of a document. Instead of writing code to dig through nested objects and arrays, you write an expression like $.store.book[*].author and get back every matching value.

This tester evaluates your expression against your JSON as you type and shows every match instantly, so you can build and debug a path interactively before dropping it into your application, a jq-style pipeline, or a tool that speaks JSONPath.

The JSONPath syntax, by example

A few building blocks cover almost everything you'll need:

• $ — the root of the document; every expression starts here.
• .key or ['key'] — step into a named property.
• [*] or .* — every element of an array or object.
• .. — recursive descent: search every level, e.g. $..price.
• [0], [-1], [1:3] — array index, last item, and slices.
• [?(@.active)] — filter to elements matching a condition.

Test JSONPath queries online

Before you bake a JSONPath expression into code or a config, it helps to see it run. Paste your JSON, type a query, and this online JSONPath tester shows every matching value as you type — so you can refine a path, confirm a filter, or debug why a selector returns nothing. It is the same role jq plays for the shell, in the browser and without an install.

JSONPath examples — common query patterns

The most common JSONPath patterns: $.name selects the top-level name field. $.users[*].email selects the email field from every element of the users array. $..price selects every price field anywhere in the document using recursive descent. $.items[0] selects the first array element; $.items[-1] the last. $.items[?(@.active == true)] filters to elements where active is true.

Paste your JSON above, type an expression, and see every matching value highlighted as you type. JSONPath is used in Postman test scripts, REST-assured, Gatling, AWS Step Functions, and Kubernetes jsonpath output — testing a query here before embedding it in code saves a debugging cycle. Recursive descent (..), array slices ([1:3]), and filter predicates are all supported. For a slower walkthrough of the same syntax, read this JSONPath tutorial with worked examples.
