About Code Beautification
Code beautification transforms minified or poorly formatted code into readable, well-structured code. This is essential for debugging, code reviews, and understanding unfamiliar codebases. Consistent formatting also reduces merge conflicts in version control.
This tool uses js-beautify, a popular and reliable library that handles modern JavaScript (ES6+), HTML5, CSS3, and JSON. The output follows common style conventions while being customizable to match your preferences.
Frequently Asked Questions
What languages does this beautifier support?
This beautifier supports JavaScript (including ES6+), HTML/XML, CSS/SCSS, and JSON. It uses js-beautify, a widely-used and reliable formatting library.
Why should I beautify my code?
Beautified code is easier to read, debug, and maintain. Consistent formatting helps teams collaborate effectively and makes code reviews more efficient. It also helps identify syntax errors that might be hidden in minified code.
Can I customize the formatting style?
Yes, you can customize indentation (spaces or tabs), indent size, line width, brace style, and various language-specific options. These settings let you match your team's coding standards.
Is my code secure when using this tool?
Yes, all code formatting happens entirely in your browser. Your code is never sent to any server, making it safe to use with proprietary or sensitive code.
Can I minify code with this tool?
This tool is designed for beautification (making code readable). For minification (making code smaller), you would need a dedicated minifier tool that removes whitespace and shortens variable names.
Does beautifying change how my code works?
No, beautification only changes whitespace and formatting. It doesn't alter the logic or functionality of your code. The beautified code will execute exactly the same as the original.
