About JSON Viewer, Formatter & Code Generator
🚀 Probably the most powerful and developer-friendly JSON Viewer extension on the Chrome Web Store!
Say goodbye to the clunky default JSON view. Built specifically for handling complex API responses and massive JSON payloads, the QubitTool JSON Viewer integrates formatting, searching, querying, diffing, and code generation into one seamless experience.
🌟 Core Developer Features:
• ⚡️ Extreme Performance: Powered by Virtual Scrolling technology, it effortlessly opens 10MB+ massive JSON files instantly without crashing your browser.
• 🔍 JSONPath Query: Built-in JSONPath engine allows you to filter and extract deeply nested JSON data just like writing SQL.
• 💻 1-Click Code Generation: Automatically generate TypeScript Interfaces, Go Structs, Python Classes, or Java Classes from any JSON payload to boost your productivity.
• 🔄 JSON Diff Tool: Compare two JSON payloads and instantly highlight the differences with our built-in diff mode.
🎨 Smart Experience & Customization:
• 🧠 Smart Detection: Automatically converts Unix timestamps to readable dates, makes URLs clickable, and displays color swatches for HEX/RGB values.
• 🌓 Developer Themes: Choose from 8 classic themes including Monokai, Dracula, Nord, and GitHub Dark/Light.
• 🛠 Highly Customizable: Adjust indent size, default expand levels, font size, and even inject your own custom CSS.
• ⌨️ Keyboard Shortcuts: Fully navigable via keyboard (Search, Copy Value, Toggle Views, etc.).
🛡️ Privacy First:
Your data security is our top priority. All JSON parsing, formatting, and processing happen locally and offline right inside your browser. We NEVER track, collect, or send your data to any external servers.
🎁 100% Free & No Ads:
Crafted with ❤️ by the QubitTool.com team. Completely free to use with zero annoying advertisements.
