Code Formatter
Format and beautify your HTML, CSS, and JavaScript code. Paste your code below to get started.
Input Code
Formatted Result
Our code formatter takes minified or poorly formatted code and makes it readable by adding proper indentation, line breaks, and spacing. It supports HTML, CSS, and JavaScript with customizable indentation settings. Whether you're debugging minified code from a production build or cleaning up code from different contributors, this tool ensures consistent, readable formatting while preserving all code functionality.
When to Use This Tool
- Cleaning up minified code for better readability during debugging
- Formatting code before sharing with team members or in pull requests
- Standardizing code style across different contributors
- Preparing code for code reviews to highlight logic clearly
- Making minified third-party code easier to understand
- Formatting dynamically generated code for debugging output
How to Use
Format Your Code
- Select the code type (HTML, CSS, or JavaScript) from the dropdown
- Paste your code into the input area
- Click 'Format' to beautify the code
- Copy the formatted code from the output area
- Use the clear button to reset and start over
Handle Mixed Code Types
- HTML can contain inline CSS (in style tags) and JavaScript (in script tags)
- The formatter will attempt to handle embedded code appropriately
- For best results, format each type separately when possible
Common Formatting Issues
- Minified code typically has all whitespace removed
- Formatting will add proper indentation and line breaks
- Syntax errors will be highlighted for correction
- Proper formatting makes errors easier to locate and fix
Examples
Minified HTML Formatting
Proper indentation helps visualize the document structure
Input
<div><p>Hello World</p></div>
Result
<div> <p>Hello World</p> </div>
CSS Property Formatting
Each property on its own line with proper indentation
Input
body{margin:0;padding:0;background:#fff;color:#333}Result
body {
margin: 0;
padding: 0;
background: #fff;
color: #333;
}JavaScript Function Formatting
Blocks within functions are properly indented
Input
function example(){return true;}Result
function example() {
return true;
}Frequently Asked Questions
Does formatting modify my code logic?
No, formatting only changes whitespace and indentation. It does not alter any code logic, variables, functions, or content. It simply makes the code more readable while preserving all functionality.
Can I use this to validate code syntax?
Yes, if there are syntax errors in your code, the formatter will indicate them. However, for thorough validation, you should use a proper linter or IDE with built-in syntax checking.
What indentation size does the formatter use?
The formatter uses 2 spaces for indentation by default, which is the most common convention in web development. This can be changed in the options if you prefer tabs or a different number of spaces.
Can I format inline CSS or JavaScript within HTML?
The formatter primarily handles the selected code type. For HTML with embedded CSS and JavaScript, you may get better results by formatting each type separately or using dedicated formatters for each language.
What happens to very long lines?
Long lines will be wrapped or kept on a single line depending on the formatter settings. Very long lines in minified code often get split across multiple lines for better readability.
Pro Tips
- •Format code before committing to version control for cleaner diffs
- •Use keyboard shortcuts (Ctrl+Shift+F) for quick formatting in some editors
- •Establish and follow a consistent code style guide across your team
- •Consider configuring your IDE to auto-format on save
- •Minified code is faster but always format for development and debugging
- •The formatted output is still valid code that can be used directly
