JSON Compare

What is JSON Compare?

JSON Compare is a developer utility that allows you to compare two JSON structures side-by-side. It formats both inputs, optionally sorts their keys alphabetically to eliminate false positives caused by key order differences, and highlights added, changed, or deleted fields.

Features

• Side-by-Side & Unified Views: View differences in a dual-column layout or a single unified stream.
• Key Sorting: Automatically sort keys alphabetically so that order differences don’t clutter your diff results.
• Validation: Real-time syntax validation with line numbers for parsing errors.
• Local & Private: All processing happens client-side in your browser. Your data is never sent to any server.

How to Compare JSON Objects

1. Paste your source JSON in the Left Editor (Original).
2. Paste your target JSON in the Right Editor (Modified).
3. Toggle options like Sort Keys if your JSON structures have the same keys but in different orders.
4. Click Compare or see the live updates in the Diff Viewer tab.
5. Review the highlighted differences: red for removals, green for additions, and blue/yellow for inline differences.
