JSON Beautifier Pro

Professional JSON Beautifier, Validator, Editor, and Comparator with on-page detection.

JSON Beautifier Pro - The Ultimate High-Performance JSON Toolkit Elevate your development workflow with the most comprehensive JSON utility for Chrome. Built for performance, designed for precision. JSON Beautifier Pro isn't just another formatter—it is a professional-grade environment for inspecting, editing, comparing, and discovering JSON data across the web. Whether you are debugging complex API responses, analyzing deep-nested configurations, or comparing structural differences between environments, JSON Pro provides a seamless, high-performance experience that stays 100% offline and secure. 🚀 WHY JSON BEAUTIFIER PRO? Modern web development demands speed and accuracy. Standard tools often fail when handling large files or "broken" JSON snippets. JSON Beautifier Pro bridges the gap between a simple viewer and a full IDE, offering a distraction-free habitat for your data. 1. Intelligent "Smart Hover" Detection The standout feature of JSON Pro is its ability to find JSON where other extensions don't. Pro Hover Sensing: Hover over any text block on any website. If it validates as JSON, a small, non-intrusive action pill appears. Zero-Lag Performance: Our detection engine uses intelligent heuristics and an optimized debouncing system (600ms), ensuring that your browser remains lightning-fast even on text-heavy pages. Instant Analytics: Click the detection trigger to see a high-level analytics card showing Size, Node count, and Nesting depth—directly on the host page. Seamless Transfer: Instantly move detected page content into the Full-Tab Editor with one click for deeper analysis. 2. The Advanced Developer Editor Experience a pro-grade code area with features focused on speed: Live Error Gutter: Don't just wonder why your JSON is invalid. Our editor highlights the specific line and provides Human-Readable error messages. Heuristic Auto-Fixer: Tired of fixing single quotes, missing quotes on keys, or trailing commas from copy-pastes? Our "Fix" button uses advanced logic to repair common structural errors automatically. Performance Indentation: One-click Beautify (2-space) or Minify for compact storage. State Persistence: Your work is automatically cached. Close the popup or tab, and your data is right where you left it when you return. 3. Structural JSON Comparator (Diff Viewer) Comparing JSON is about more than just string differences—it's about structure. Side-by-Side Diff: Our dedicated comparator provides a visual breakdown of your data. Intelligent Key Sorting: Before comparing, JSON Pro can normalize your keys. This allows you to find actual data differences even if the API returned objects in a different order. Visual Highlighting: Color-coded additions (Green) and deletions (Red) make identifying changes intuitive. 4. Interactive Tree Navigation Exploration is better than reading. Deep-Nested Support: Collapse or expand levels of data at will. Data Type Visualizer: Clearly distinguish between Strings, Numbers, Booleans, and Nulls with a curated color palette. Copy Logic: Click any key or value in the tree to copy it instantly to your clipboard. 5. Real-Time Structural Analytics Knowledge is power. Every JSON set you load is instantly analyzed to provide: Memory Footprint (Size): Accurate byte-count reflecting your real-time edits. Node Count: Total count of keys and array elements to gauge complexity. Nesting Depth: Maximum depth of the data tree. Root Type: Instant identification of Array vs. Object structures. 💎 PREMIUM DESIGN & EXPERIENCE Dark Mode by Default: Optimized for late-night coding sessions with a sleek, Slate-themed high-contrast interface. Glassmorphism UI: Modern aesthetics with subtle blurs, pulsing core glows, and premium Lucide-react iconography. Full-Page Mode: Need more space? Expand the extension from a popup to a full browser tab with a single click. Responsive Layout: A draggable, resizable divider allows you to customize the ratio between your Code and Tree views. 🔒 PRIVACY & SECURITY FIRST In the world of sensitive API keys and user data, privacy is non-negotiable. 100% Offline: JSON Beautifier Pro performs all operations locally on your machine. No Data Collection: Your JSON data never leaves your browser. No external API calls, no tracking, and no cloud storage. Zero Permissions Over-reach: We only request permissions necessary to detect JSON on pages and save your local preferences. ⚡ KEY FEATURES AT A GLANCE ✅ Beautify & Minify: Instant formatting and compaction. ✅ JSON Fixer: Automatically repair broken/malformed JSON. ✅ Smart Detect: Hover over any text to reveal JSON contents. ✅ Side-by-Side Diff: Identify structural changes between two JSON sets. ✅ Interactive Tree: Navigate complex data with collapsible nodes. ✅ Live Validation: Gutter-based error reporting. ✅ Real-time Stats: Track Size, Nodes, and Depth. ✅ Persistence: Automatically saves your last-used state. ✅ Pro Themes: Seamless Dark and Light mode support. ✅ Context Menu: Select any text and right-click to "Open in JSON Pro". 🛠 BUILT FOR THE MODERN DEVELOPER Whether you are a Backend Engineer debugging microservices, a Frontend Developer working with complex state, or a Data Scientist analyzing logs, JSON Beautifier Pro is designed to be the only JSON tool you'll ever need.
