Makes JSON easy to read.

What is JSON Formatter?

JSON Formatter is an advanced browser add-on specifically for Microsoft Edge, used to simplify the view of JSON data by auto-formatting it. This tool comes packed with features, including a fast response time on lengthy JSON pages, a pleasing dark mode, syntax highlighting, and collapsible trees with visual indent guides. It enhances viewing by making URLs clickable and has almost no impact on non-JSON pages. The add-on works on any valid JSON page regardless of the URL, offering buttons also to switch between raw and parsed JSON. Notably, it values user's privacy by avoiding any form of tracking or advertising.
