About Code Beautifier
Beautify and format HTML, CSS, JavaScript and JSON code. Free online code formatter.
Code Beautifier formats messy HTML, CSS, JavaScript and JSON into clean, consistently indented code with one click. Paste a minified stylesheet, a single-line script tag or a compact JSON blob, choose your indentation width, and the beautifier rebuilds the structure with logical line breaks, aligned properties and readable nesting. Proper formatting makes bugs easier to spot, reviews faster and hand-overs smoother, especially when you inherit code written by someone else. Everything runs locally in your browser, so proprietary source code never leaves your machine. Use the Code Beautifier while debugging front-end pages, cleaning pasted snippets or preparing code for a pull request. It is free, needs no sign-up and works on any modern browser.
