Overview

Open source JSON viewer for Chrome that makes JSON and JSONP responses much easier to read, explore, and debug.

Whether you're working with APIs, inspecting responses in the browser, or just trying to make sense of raw JSON data, this extension gives you a cleaner and more developer-friendly way to view structured data right in Chrome.

✨ Features:
• JSON & JSONP support
• Syntax highlighting
• Collapsible trees with indent guides
• Clickable URLs
• Copy and Download JSON data
• Toggle between raw and parsed JSON

🛠 Perfect for:
• Developers working with APIs
• Debugging JSON responses in the browser
• Quickly exploring nested objects and arrays

📦 Why use it?
Raw JSON in the browser can be hard to read and navigate. This extension transforms JSON into a structured, interactive view so you can inspect data faster and with less friction.
