About the Code Formatter

What is code formatting?

Code formatting is the process of restructuring source code to follow consistent indentation, spacing, and line-break conventions without changing its functionality. Well-formatted code is easier to read, review, debug, and maintain. Consistent formatting across a team reduces cognitive load during code reviews and helps catch logic errors that might hide in poorly structured code.

Supported languages and features

Our code formatter supports multiple languages including JavaScript, TypeScript, HTML, CSS, JSON, XML, SQL, and more. It applies standard formatting rules for each language: proper indentation levels, consistent brace placement, aligned properties, and clean line breaks. You can paste minified or messy code and get a clean, readable version instantly.

When to use a code formatter

Use the code formatter when you receive minified production code that needs to be debugged, when copying code snippets from Stack Overflow or documentation that use different conventions, when reviewing API responses in JSON or XML format, or when preparing code for documentation or presentations. It is also useful for quickly standardizing code before committing to a repository.
