Source Code Formatter & Beautifier EN

With the help of the lightweight, cross-browser addon Source Code Formatter & Beautifier, you can quickly and easily beautify codes in your browser. As input languages, this add-on supports HTML, CSS, and JavaScript. You have two options for browsing files: drag and drop a file into the textarea, or use the (+) button in the UI's top-left corner (left side). The earlier method is preferred because the interface can be updated in accordance with the input file's coding language thanks to automatic detection (no need to adjust the input language manually). Without an internet connection, this add-on for Source Code Formatter & Beautifier can function. It makes use of the free library js-beautify, which is available on GitHub.
