About Pretty JSON

Pretty JSON is a lightweight Chrome extension that brings Firefox's beloved JSON viewing experience to Chrome. When you open a JSON file in your browser, it automatically formats and displays it with beautiful syntax highlighting, making complex data structures easy to read and navigate. Arrays and objects are initially collapsed with expandable "+" icons, allowing you to drill down into the data structure at your own pace. Features include expand/collapse all buttons, one-click copy, and a clean dark theme interface. Works completely offline with no external dependencies. Developed by AIO.com.ai for developers and data professionals who work with JSON files daily.
