📖 Usage Guide
Step 1: Input JSON Objects
Enter two JSON objects in the input fields. You can paste JSON data or use the 'Load Sample' button for examples.
Step 2: Compare Objects
Click the 'Compare' button to analyze the differences between the two JSON objects.
Step 3: Review Differences
View the comparison results showing added (+), removed (-), and unchanged fields with color coding.
Step 4: Copy or Share
Copy the diff results to clipboard or use the swap function to compare in reverse order.

🔬Technical Guide
JSON Comparison AlgorithmThis tool uses a recursive comparison algorithm that traverses JSON objects depth-first, comparing keys and values at each level. It handles nested objects, arrays, and primitive values, providing detailed path information for each difference found.
Diff Output FormatThe diff results are presented in a unified diff format with color coding: red for removed fields (-), green for added fields (+), and gray for unchanged fields. Each line shows the complete path to the changed property.
Performance and LimitationsThe comparison is performed client-side for privacy and speed. Large JSON objects (>10MB) may take longer to process. The tool handles circular references gracefully and provides clear error messages for invalid JSON.
