Instant Processing

All formatting runs directly in your browser with zero server round-trips. Your code is formatted the moment you click the button, regardless of file size or complexity. No waiting, no loading spinners.

Private & Secure

Your source code never leaves your device. Unlike server-based formatters, our tool processes everything client-side. This makes it safe for proprietary code, API keys, and sensitive configuration files.

Clean Output

Get consistently formatted code with proper indentation, normalized line endings, and trimmed trailing whitespace. The output follows widely accepted coding conventions for each supported language.

What is a Code Formatter and Why Should You Use One?

A code formatter is a tool that automatically restructures source code to follow consistent style guidelines. It adjusts indentation, spacing, line breaks, and other formatting elements to make code more readable and maintainable. Consistent formatting is essential for collaborative development, code reviews, and long-term project maintenance.

Messy or inconsistently formatted code is harder to read, debug, and maintain. Studies show that developers spend significantly more time reading code than writing it, so investing in clean formatting pays dividends in productivity. Our free online code formatter handles 8 popular languages and runs entirely in your browser.

Supported Languages

JSON: Uses the native JSON parser for perfectly accurate formatting and validation. Detects and reports syntax errors with precise error messages.
JavaScript & TypeScript: Normalizes indentation based on brace and bracket nesting. Handles functions, objects, arrays, and control structures.
HTML & XML: Formats tag nesting with proper indentation. Handles self-closing tags, void elements, and nested structures.
CSS: Formats selectors, properties, and values with consistent indentation. Supports minification that strips comments and whitespace.
Python: Normalizes indentation levels based on code block structure using colons and brackets.
SQL: Formats queries with keyword-based line breaks and indentation for SELECT, FROM, WHERE, JOIN, and other clauses.

Frequently Asked Questions

What programming languages does the code formatter support?▼

Our code formatter supports 8 popular languages: JavaScript, TypeScript, HTML, CSS, JSON, Python, SQL, and XML. Each language has tailored formatting rules that handle its specific syntax patterns, such as brace-based nesting for JavaScript or keyword-based indentation for SQL.

Is the code formatter free to use?▼

Yes, our code formatter is completely free with no usage limits, no sign-up required, and no hidden fees. You can format and minify as much code as you need without any restrictions.

Does the formatter send my code to a server?▼

No. All formatting and minification happens entirely in your browser using client-side JavaScript. Your code never leaves your device, ensuring complete privacy and security for sensitive or proprietary source code.

What is the difference between formatting and minifying code?▼

Formatting (beautifying) adds proper indentation, line breaks, and spacing to make code readable and maintainable. Minifying does the opposite: it removes all unnecessary whitespace, comments, and line breaks to reduce file size, which is useful for production deployment.

Can I customize the indentation style?▼

Yes, you can choose between 2 spaces, 4 spaces, or tab-based indentation. Select your preferred indent size from the dropdown before clicking the Format button, and the output will use your chosen indentation consistently throughout.

How accurate is the code formatting?▼

For JSON, the formatter uses the native JSON parser for perfectly accurate results. For other languages, it applies reliable indentation normalization based on syntax patterns like braces, brackets, and keywords. While it handles the vast majority of common code patterns correctly, extremely complex or unconventional syntax may require manual adjustments.
