JSONPath Query Tool - Extract JSON Data Online
Query and extract data from JSON using JSONPath expressions. Supports nested queries, filters, and wildcards
JSONPath Syntax Quick Reference
About This JSONPath Query Tool
Tool for querying JSON data with JSONPath expressions. This tool is part of the AI JSON Tools collection, providing specialized functionality for developers working with complex JSON documents. All processing happens entirely in your browser—your data never leaves your device.
How It Works
The tool evaluates JSONPath expressions against your JSON data using the jsonpath library. Simply paste your JSON data into the left panel, enter a JSONPath expression like $.store.book[*].author, and click Query. The results appear instantly with a count of matched items.
Common Use Cases
Developers use this tool for: 1) Extracting specific fields from large API responses, 2) Filtering JSON arrays by property values, 3) Debugging JSON data structures, 4) Testing JSONPath expressions before using them in code, 5) Exploring nested JSON documents interactively.
Technical Details
The tool is built with vanilla JavaScript and the jsonpath 1.1.1 library loaded via CDN. It supports the full JSONPath specification including recursive descent (..), array slicing ([start:end]), filter expressions ([?(@)]), and wildcard (*) matching.
Privacy & Security Guarantee
No data leaves your browser. All JSONPath queries run locally using JavaScript. This means you can safely query sensitive JSON data including API credentials, user records, and proprietary data structures. There is no server-side processing.
JSONPath Query Features - Why Use This Tool
Deep Search
Use $.. syntax to search nested JSON at any depth. Find all matching properties regardless of nesting level.
Array Filtering
Filter arrays with [?(@.price < 10)] expressions. Combine multiple conditions for precise data extraction.
Instant Results
All queries run in your browser with instant feedback. See result counts and formatted JSON output immediately.

What is the difference between JSONPath and JSON Pointer?
JSONPath is a query language (like XPath for XML) that supports wildcards, filters, and recursive descent. JSON Pointer (RFC 6901) is a simpler path syntax that only supports exact property access. JSONPath is more powerful for querying and filtering JSON data.
Can I use JSONPath to extract nested arrays?
Yes. Use $..property for deep recursive search, or $.path.to.array[*] for all elements of a specific array. Array filtering with [?(@.field)] is also fully supported.
Does this tool support JSONPath filter expressions?
Yes. Filter expressions like $.store.book[?(@.price < 10)] are fully supported using the jsonpath 1.1.1 library. You can use comparison operators (<, >, ==, !=, <=, >=) and logical operators (&&, ||) inside filters.
Is my JSON data safe?
Yes. All queries execute entirely in your browser using JavaScript. Your JSON data is never uploaded to any server—it stays on your device at all times.
