Free Online Code Formatter & Beautifier

TOOLBeans code formatter instantly beautifies and formats JavaScript, TypeScript, HTML, CSS, SCSS, JSON and XML code directly in your browser no server upload, no account required. Paste messy, minified or unindented code and get clean, properly-indented output in milliseconds.

Switch to Minify mode to compress your code by removing whitespace, comments and unnecessary characters reducing file size for production deployment. The Diff view shows exactly which lines changed between input and output so you can review every formatting decision. Auto-language detection identifies your code type automatically so you don't have to select it manually.

Upload code files directly using the file picker supports .js, .ts, .html, .css, .scss, .json and .xml files. All formatting runs 100% client-side using pure JavaScript engines, meaning your code never leaves your device and the tool works even without an internet connection after the initial page load.
