About Code Formatting

Code formatting is the process of organizing code with consistent indentation, spacing, and structure. It improves readability, maintainability, and reduces the likelihood of errors. Proper formatting is essential for collaborative development, code reviews, and adhering to industry standards. Tools like this Code Formatter help automate the process, ensuring your code is always clean and professional.

Whether you are working on a solo project or as part of a team, consistent code formatting saves time and makes your codebase easier to navigate. This tool supports popular languages like JavaScript, TypeScript, JSON, and CSS, each with their own best practices and conventions.
