Which programming languages can this formatter handle?

This tool supports XML, SQL, CSS, HTML, and JavaScript. Select the language from the dropdown before formatting to apply language-specific formatting rules. Each language has its own indentation rules and syntax conventions.

What is the difference between beautifying and minifying code?

Beautifying (formatting) adds proper indentation, line breaks, and spacing to make code readable for humans. Minifying removes all unnecessary whitespace to reduce file size for production. Minified code is smaller but impossible to read. Use beautify for development and readability, minify before deploying.

How do I format XML or HTML?

Select XML or HTML from the language dropdown, paste your code, and click Format. The formatter adds proper indentation and organizes nested elements for readability. It handles self-closing tags, attributes, and mixed content correctly. Use the Copy or Download buttons to save the result.

What does SQL formatting do?

SQL formatting organizes your queries with proper indentation for SELECT, FROM, WHERE, JOIN, and other clauses. It capitalizes keywords by default (can be toggled off), adds line breaks between clauses, and aligns operators and values. This makes long, complex queries readable and easier to debug.

Is my code kept private?

Yes. All code formatting happens entirely in your browser. Nothing is sent to any server, stored online, or logged. Your code is processed by JavaScript running locally and disappears when you close or refresh the page. Use it confidently for proprietary source code, API keys, credentials, or any sensitive code.

Can I undo changes after formatting?

Use Ctrl+Z to undo any formatting changes, or click Copy to restore the original text from the input. The original text is kept in the input area as long as you do not modify it. Use the Compare button to see your formatted code side-by-side with the original.
