A dark-mode, offline-ready JSON viewer. No tracking, no ads. Tired of JSON viewers that look ugly, crash on large files, or ask for weird permissions? Meet Clean JSON Viewer Pro, the safest and fastest way to debug APIs. We built this because developers deserve tools that are modern, beautiful, and strictly private. 🔥 KEY FEATURES: • Privacy First: No analytics. No tracking. 100% Offline. • Smart Dark Mode: Easy on the eyes for late-night coding. • Manifest V3 Ready: Future-proof using Google's latest standard (won't break in 2026). • Syntax Highlighting: Automatically formats .json files with VS Code-style colors. • One-Click Copy: Grab the formatted JSON instantly. 🔒 SECURITY GUARANTEE: This extension runs entirely offline within your browser. It does not send your data to any server. Check our permissions—we keep it clean. 💡 SUPPORT THE DEVELOPER: This project is maintained by an independent developer. If it saves you time, consider buying me a coffee via the link inside the app!
