About CSS Beautifier

Minified or inconsistently formatted CSS is difficult to read, debug, and maintain. Xevon Tools' CSS Beautifier reformats any CSS stylesheet with clean indentation, consistent line breaks, and each property on its own line. Optional alphabetical property sorting brings additional organization to large rule blocks. The tool handles complex selectors, media queries, and large stylesheets without performance issues. This is especially useful for debugging production CSS, cleaning up legacy stylesheets before migration, formatting vendor-generated code, and preparing code samples for documentation. Everything runs in your browser so your stylesheets stay private. For the inverse operation — compressing CSS for production — use the companion CSS Minifier tool.

Frequently asked questions

Yes. Optional property sorting organizes declarations within each rule in alphabetical order. This can improve consistency and make it easier to find specific properties in large rule blocks.
The tool is designed for standard CSS. SCSS and Less files may format correctly for the CSS-compatible portions, but preprocessor-specific syntax like nesting and variables may not format perfectly.
For CSS minification, use the dedicated CSS Minifier tool. The Beautifier focuses on making CSS readable, while the Minifier focuses on making it as small as possible.
Yes. All formatting happens client-side in your browser. No CSS code is sent to any server.
