JSONPath Tester

JSONPath is a query language for JSON, similar to how XPath works for XML. It allows you to extract specific data from complex JSON structures using simple expressions. This JSONPath tester helps you build and validate expressions before using them in your code or automation workflows.

The Problem: Extracting Data from Complex JSON

Modern APIs return deeply nested JSON responses with hundreds of keys. Manually navigating through these structures to find the data you need is tedious and error-prone. Without proper tools, you might write incorrect expressions that fail silently or return unexpected results.

• API responses contain deeply nested data structures
• Extracting specific values requires complex code
• Testing expressions in production is risky
• Debugging failed extractions wastes development time

The Solution: Online JSONPath Tester

This free JSONPath evaluator lets you test expressions against sample JSON data in real-time. See exactly what data your expression extracts before deploying it to production. Perfect for building reliable data extraction logic for APIs and automation workflows.

Key JSONPath Features Supported

• Root Access ($) - Start from the root of your JSON document
• Property Access (.key) - Navigate to specific properties
• Array Wildcards ([*]) - Select all items in an array
• Array Indices ([0], [-1]) - Select specific array elements
• Recursive Descent (..) - Search all levels for matching keys
• Filter Expressions ([?()]) - Filter arrays based on conditions
• Array Slicing ([0:2]) - Select ranges of array elements

Perfect for n8n Data Extraction

When building n8n automation workflows, you often need to extract specific data from API responses. JSONPath expressions work perfectly in n8n Function nodes and expressions, allowing you to:

• Extract nested values from HTTP Request responses
• Filter arrays based on specific criteria
• Navigate complex webhook payloads
• Transform data without writing custom code

Common JSONPath Examples

• $.store.book[*].author - Get all authors from a bookstore
• $.users[?(@.active==true)] - Filter for active users only
• $..price - Find all price values recursively
• $.orders[-1] - Get the last order in an array
