JSON Quick Preview is a Chrome add-on designed to enhance the way users interact with JSON data on web pages. This free tool automatically detects and formats any selected JSON text, displaying it in a convenient floating box that can be easily moved around the screen. With features such as syntax highlighting for various data types and memory for position and size, it streamlines the process of reading and copying JSON without the need to switch between tools.

The add-on is particularly useful for developers and testers who need to debug API responses or inspect raw JSON data in various contexts. It provides a seamless experience with one-click copy functionality and a quick close option for the preview box. Future updates aim to include additional features like theme toggles and keyboard shortcuts for enhanced usability.
