What is JSON[B] Viewer?

JSON[B] Viewer is a web-based Microsoft Edge extension designed for handling JSON documents. It stands as an advanced tool that offers functionalities for viewing, editing, transforming, and comparing JSON files. Users should, however, be mindful of potential crashes with other JSON highlighters and the need to manually enable local files and incognito tabs viewing. The tool further offers robust support for local files, provided users enable this in edge://extensions.
