JSON Diff Made Easy — Compare & Visualize Changes in One Click

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
