Compare Data with Advanced JSON Diff & Comparator
SUDTCore's JSON Comparator is a professional-grade diffing utility that highlights additions, deletions, and modifications between two JSON objects. Featuring a high-fidelity Monaco Diff Editor (the engine behind VS Code), it provides superior side-by-side and inline delta calculations.
Why Use our Key-Sorting Comparator?
Recursive Key Sorting: Intelligently aligns matching properties alphabetically, preventing false positive diffs caused by key-order discrepancies.
Deep Statistics: Explicit Added, Removed, and Modified counts to quickly verify structural changes.
Change Path Tree: Browse every changed field by its dotted JSON path with before/after values.
Downloadable Reports: Export a full JSON diff report for documentation and code review.
How to use:
- Paste or drag the "Original" JSON into the Left panel.
- Paste or drag the "Modified" JSON into the Right panel.
- Choose options like Sort Keys or spacing in the controls.
- Click Compare JSON or press Ctrl+Enter.
- Download a diff report or explore changes in the Change Tree.
