If you’ve ever tried comparing two large JSON files, you know how messy it can get.
That’s why I built a JSON Compare tool inside JSONViewer.tools — and it’s not your typical plain-text diff.
🔹 What Makes It Different?
1️⃣ Side-by-Side JSON View
Paste or upload two JSON files
See additions, removals, and updates highlighted instantly
Works even with deeply nested structures
2️⃣ Visual Diff Diagram (the game-changer)
Converts your JSON changes into an interactive diagram
Collapsible nodes so you can explore just the parts you care about
Perfect for explaining changes to non-technical teammates
3️⃣ Privacy-Friendly
Everything runs entirely in your browser
No data is stored or sent to any server (unless you choose to share)
🖼 How It Works
Paste or upload both JSONs
Switch between Side-by-Side and Diagram View
Export the visual diff as an image or copy the merged JSON
Here’s a sneak peek:
🎯 Why Use It?
Debug API responses faster
Review config changes with ease
Understand large, complex JSON without losing context
