JSON Formatter

JSON Formatter is the original Chrome extension that makes reading JSON files effortless by auto-formatting JSON data directly in your browser tab. It delivers fast performance even on very large JSON documents and supports features such as syntax highlighting, collapsible trees with indent guides, and clickable URLs for easy navigation.

With a sleek optional dark mode, switching between raw and parsed JSON views is simple through toggle buttons. The extension ensures minimal impact on non-JSON pages, maintaining browser speed with less than 1 millisecond of overhead, while respecting your privacy — no tracking or ads involved.
