What is a Code Beautifier? Complete Guide
A code beautifier is a developer tool that formats source code with consistent indentation, spacing, and structure for improved readability. Our 2026 code beautifier supports HTML, CSS, JavaScript, JSON, and XML with auto-indentation, syntax-aware formatting, bracket matching, comment preservation, line wrapping control, and one-click copy. Unlike basic formatters that only add spaces, our tool uses language-specific parsing for accurate, clean code formatting. Perfect for developers debugging code, reviewing pull requests, learning code structure, or cleaning up minified files. All formatting happens client-side with zero data transmission.
How to Use the Code Beautifier
- Select your programming language (HTML, CSS, JavaScript, JSON, or XML)
- Paste your minified or messy code into the input box
- Choose indentation options (spaces or tabs, indent size)
- Select line wrapping preferences
- Click "Beautify" to format your code
- Review the clean, formatted output
- Click "Copy" to copy the beautified code
- Paste into your editor or use immediately
