Browser JSON Viewer

Browser JSON Viewer automatically detects raw JSON responses and transforms them into a clean, interactive visual tree - no copy-pasting into external tools required. How it works Whenever you open a URL that returns a raw JSON response - a REST API endpoint, a local JSON file, or any direct link to a .json file - the extension instantly replaces the plain text with a rich interactive viewer powered by visual-json. Features - Interactive tree view - expand and collapse nested objects and arrays to explore complex structures - Search - quickly locate keys or values anywhere in the document - Form view - inspect and edit individual fields in a structured form layout - Works on API endpoints - open any REST API GET endpoint directly in the browser and get a formatted view instantly - Works on local JSON files - drag and drop a .json file into the browser or open it with File -> Open, and it renders the same way - Zero configuration - install and it just works on every tab, automatically - Style isolated - runs inside a Shadow DOM so it never interferes with page styles Use cases - Debugging REST APIs without Postman or DevTools - Quickly inspecting configuration files or data exports saved as .json - Exploring API responses from third-party services - Sharing API response URLs with teammates who can view them formatted without any setup
