JSON Viewer Pro automatically detects and formats JSON responses in your browser. A fast, lightweight alternative to JSON Formatter with zero tracking. FEATURES - Collapsible tree view with syntax highlighting - Search across keys and values with real-time highlighting - Copy individual values or full JSON paths (JSONPath style) - Toggle between formatted tree view and raw JSON - Light, dark, and auto themes (follows your system preference) - URL detection — clickable links in string values - File size display in the toolbar WHY JSON VIEWER PRO? - Zero tracking or analytics — your data stays on your device - No ads, donation popups, or injected content of any kind - No checkout hijacking or third-party scripts - Fast and lightweight — minimal permissions (storage only) - Clean, modern UI with dark mode support - 100% open source — inspect every line of code on GitHub - Built with Manifest V3 for maximum security PRIVACY FIRST Other JSON extensions have been caught injecting donation popups into checkout pages, tracking user locations via GeoIP, and sending browsing data to third-party servers. JSON Viewer Pro takes the opposite approach: we collect nothing, track nothing, and inject nothing beyond formatting your JSON. PERFECT FOR - API development and debugging - REST API response inspection - JSON configuration file viewing - Webhook payload debugging - Any page that returns application/json PERMISSIONS - Storage: saves your theme preference (light/dark/auto) only - Host permissions: needed to detect JSON content type on any URL (exits immediately on non-JSON pages — no data collected)
