Paste the original JSON in the left panel and the modified JSON in the right panel. The tool performs a deep recursive comparison and shows every added, removed, and unchanged property with its full path.
Features
Deep Comparison — Recursively compares nested objects and arrays to any depth.
Path Display — Each difference shows the full dot-notation path (e.g., user.address.city).
Color-Coded Output — Green for additions, red for removals, neutral for unchanged.
Statistics Bar — Shows counts of added, removed, and unchanged properties at a glance.
Copy Results — Export the diff summary for documentation or code review.
Common Use Cases
API Response Comparison — Compare responses across API versions to detect breaking changes.
Data Migration — Verify data integrity after transformations or migrations.
Code Review — Include diff summaries in pull request descriptions.
Why Use This Tool
Generic text diff tools show line-by-line differences that miss the semantic structure of JSON. This tool understands JSON hierarchy, showing you exactly which properties changed at which nesting level.
