Compare two JSON documents and see the semantic differences between them. Identify added, removed, and modified properties with visual diff viewer. Perfect for API response validation, configuration file comparison, and data structure analysis.
Enter JSON documents in both fields above and click compare to see differences
Before (Left JSON):
{
"user": {
"id": 123,
"name": "John Doe",
"email": "john@example.com"
},
"status": "active"
}After (Right JSON):

"phone": "+1234567890"
},
"status": "active",
"lastLogin": "2024-01-15"
}✓ Detects: name change, phone addition, lastLogin addition

Compare API responses before and after changes to ensure backward compatibility
Track changes in configuration files and settings across environments
Validate test results and compare expected vs actual JSON outputs
The JSON Compare Tool is a powerful online utility that allows you to compare two JSON documents and identify semantic differences between them. Unlike simple text-based comparison tools, this advanced tool understands JSON structure and can identify added, removed, and modified properties regardless of formatting, whitespace, or property order.
Semantic Comparison: Understands JSON structure, not just text
Visual Diff Viewer: Color-coded differences with clear highlighting
Path Tracking: Shows exact location of each difference
Multiple View Modes: Visual and text-based difference views
Export Options: Copy results to clipboard for sharing
URL Parameter Support: Load JSON via URLs for automation
Flexible Input: Supports both JSON and JavaScript object notation
Customizable Formatting: Adjustable indentation for readability
API Development: Compare request/response payloads during development
Configuration Management: Track changes in config files across environments
Testing & QA: Validate expected vs actual JSON outputs in tests
Data Migration: Verify data transformations and migrations
Debugging: Identify unexpected changes in JSON data structures
Pro Tip: This tool processes all data locally in your browser for maximum security and privacy. No JSON data is sent to external servers, ensuring your sensitive information remains protected.
