About the C Beautifier

This tool reformats C source code with proper indentation. Preprocessor directives, strings, character literals and comments are preserved exactly as-is.

What it does

  • Indents functions, conditionals, loops and blocks.
  • Preserves strings and character literals.
  • Keeps preprocessor directives on their own lines.
