Frequently asked questions

Which JSONPath dialect is supported?

The Goessner-style JSONPath as extended by jsonpath-plus. Filters <code class="font-mono">?(@.price &lt; 10)</code>, recursive descent <code class="font-mono">..</code>, slices <code class="font-mono">[0:5]</code>, and unions <code class="font-mono">[0,2,4]</code> all work.

Why is my expression returning nothing?

Double-check the root. Expressions must start with <code class="font-mono">$</code>. Quote keys with special characters: <code class="font-mono">$["my-key"]</code>.

What is JSONPath Tester?

A JSONPath Tester is a tool that evaluates JSONPath expressions against a JSON document and shows the matching results. It runs queries live, returning both the path and value of each match, and supports filters, slices, and recursive descent for navigating nested data. Working client-side in the browser, it lets developers test and refine JSONPath queries without sending the JSON to a server.

Features

Live evaluation

Type an expression and see matches update instantly against your JSON.

Filters, slices & recursion

Supports [?()] filters, [start:end] slices, wildcards, and the .. recursive-descent operator.

100% private

Queries run client-side — your JSON is never uploaded.

Example

Input

JSON: {"store":{"book":[{"price":8.95},{"price":12.99}]}}   ·   Path: $.store.book[*].price

Output

[8.95, 12.99]

Common use cases

  1. 1

    Extract nested values

    Pull every price, id, or field from a deep JSON payload with one expression.

  2. 2

    Prototype API mappings

    Refine the JSONPath a workflow tool (n8n, Zapier) will use before wiring it up.

  3. 3

    Debug a query

    Confirm exactly which nodes a JSONPath matches on real data.

Summary
