JSON Live Editor is a versatile online and offline code editor specifically designed for working with JSON documents. Developed by Stephan Ringel, this free tool is perfect for manipulating and displaying JSON data outputted by a REST API.

With JSON Live Editor, you can easily edit and preview your HTML, CSS, and JavaScript code. The syntax highlighting, search, replace, and autocomplete features make coding a breeze. You can even drop code from your file system and save your code to the file system for easy access.

One of the standout features of JSON Live Editor is its versioning capability, which allows you to easily track changes using your browser's history and local storage. Sharing your code is also made simple with the ability to generate a URL for easy sharing with others.

Additionally, JSON Live Editor includes a JSON Validator to ensure that your JSON is valid and editable. The tool also offers convenient key shortcuts for quick actions like live updates, toggling between preview and code editor, and searching and highlighting code.

Please note that JSON Live Editor may clash with other JSON highlighters and beautifiers, such as 'JSONView', 'Pretty JSON', or 'Sight'. It is recommended to disable these extensions before using JSON Live Editor.
