Browser JSON Viewer is a free Chrome extension designed to enhance the experience of working with raw JSON data. This tool automatically detects JSON responses from various sources, including REST API endpoints and local JSON files, and presents them in a user-friendly, interactive visual tree format. Users can easily explore complex structures by expanding and collapsing nested objects and arrays, making it ideal for developers and data analysts alike.

The extension offers several useful features such as a search function to quickly locate specific keys or values, a form view for inspecting and editing individual fields in a structured layout, and zero configuration setup. It operates seamlessly within the browser, ensuring that it does not interfere with existing page styles. This makes it a valuable asset for debugging APIs, inspecting configuration files, and sharing formatted responses with colleagues.
