Beautify and format HTML, CSS, JavaScript, SQL, XML, and other code.
Readable code is debuggable code. When you receive minified JavaScript from a CDN, a single-line SQL query from a log, or collapsed HTML from a CMS export, you need to format it before you can understand it. These formatters and beautifiers cover all the major languages and formats developers work with: HTML, CSS, JavaScript, TypeScript, SQL, XML, YAML, and more. Each formatter applies proper indentation, line breaks, and syntax structure. They're especially useful during code review, debugging production issues, or reformatting code snippets before pasting them into documentation. All formatting runs in your browser with zero server calls.
