Overview

Auto-formats JSON, captures API calls, decodes JWTs, converts timestamps, and generates TypeScript interfaces. 100% local.

JSON Formatter+ is a high-performance, privacy-focused Google Chrome extension designed for modern web developers, API engineers, and QA specialists. It instantly turns raw, unreadable browser JSON payloads into an interactive, color-coded, searchable tree view. Beyond formatting, it serves as a lightweight API productivity suite—capturing live background fetch and XHR network requests with HTTP status/method filtering, auto-decoding JWT tokens, converting Unix/ISO timestamps, offering a ⌘K Command Palette, generating TypeScript interfaces with one click, and providing performance-virtualized rendering. KEY FEATURES: ⚡ Virtual-DOM & Lazy Node Engine: Instantly renders massive JSON payloads without sluggish DOM re-renders or browser freezing. 🔒 100% Air-Gapped & Local: No data ever leaves your computer—zero analytics, zero remote servers, complete data privacy for sensitive tokens and API keys. ⌨️ Command Palette & Hotkeys: Power-user friendly with ⌘K / Ctrl+K overlay, Alt+T theme toggling, and Alt+L log clearing. 🛠️ Developer-Centric Utilities: Built-in JWT payload decoder, epoch timestamp visualizer, JSON file export, and instant TypeScript interface creation. 📡 Advanced API Inspector: Inspect REST/XHR requests made by single-page apps with HTTP method (GET, POST, PUT, DEL) and status (2xx, 4xx, 5xx) filtering. 📋 Paste & Format Sandbox: Quickly validate, search, and beautify arbitrary JSON snippets from Slack, Postman, or terminal logs. HOW TO USE: 1. Open any raw JSON endpoint in Google Chrome. 2. Watch JSON Formatter+ automatically render an interactive, searchable tree view. 3. Press ⌘K or Ctrl+K to launch the Command Palette for instant search across keys and values. 4. Click the extension pin icon to access the Popup Dashboard featuring Paste & Format, API Calls, and Settings.
