About Fractured JSON — Formatter
Fractured JSON — Formatter
Transform raw, unreadable JSON into a beautiful, interactive, and highly optimized viewing experience.
Fractured JSON is a powerful Chrome extension port of the popular FracturedJson library. It automatically detects raw JSON pages and replaces them with a sleek, macOS-window-style viewer. Built from the ground up for speed and usability, it guarantees that even massive JSON payloads load smoothly without freezing your browser.
Whether you are a developer, data analyst, or just someone staring at API endpoints, this extension drastically improves your workflow.
✨ Key Features
🎨 Beautiful Syntax Highlighting: Keys, strings, numbers, booleans, and punctuation are all assigned distinct, easy-to-read colors.
🌗 Three Built-in Themes: Choose a look that suits you best—includes Dark, Light, and Cobalt modes.
⚡ Three Formatting Modes: Switch instantly between Pretty-print (standard layout), Minify (compressed), and Near-minify (a smart hybrid that saves vertical space while remaining readable).
🏗️ Zero UI Freezing (Worker-based): Intensive JSON formatting is offloaded from the main browser thread to web workers. Your browser stays fast and responsive, even when rendering gigantic payloads.
🔒 Works on Strict CSP Pages: Need to view api.github.com or other secure endpoints with strict Content-Security-Policy rules (default-src 'none')? Fractured JSON gracefully handles these via a robust background service worker fallback.
🖥️ Polished UI & Sticky Controls: Enjoy a clean macOS-style window chrome. The toolbar and title bar stay pinned to the top, so you only scroll the data you care about.
🔢 Line Numbers: Easily toggle the line number gutter on or off.
📋 Download & View Raw: Instantly toggle between the formatted view and the original raw text, or click to save the formatted result cleanly as a
.json
file.
🔄 Persistent Preferences: The extension remembers your preferred theme, format mode, and line-number settings automatically across all tabs.
Stop wrestling with unformatted API responses or sluggish, thread-blocking extensions. Install Fractured JSON today for a fast, beautiful, and secure data-viewing experience!
