C Formatter and Beautifier

Keep your C code readable and consistent with the C Formatter & Beautifier. Paste any snippet, pick an indent width, and the tool applies sensible spacing, indentation, and line wrapping based on a set of pragmatic defaults inspired by clang-format and classic K&R style.

Capabilities

• Smart indentation: Choose 2, 4, 6, or 8 spaces to match team preferences.
• Whitespace cleanup: Consolidates stray line breaks, aligns braces, and adds trailing newlines.
• Live preview: The formatter runs after a short debounce so you see changes without hammering the CPU.
• File-ready output: Download the formatted version as formatted.c or copy it back into your editor.
• Error handling: If js-beautify encounters an issue, the tool notifies you and highlights the problem area.

Formatting tips

1. Paste or upload your source into the left panel. The tool supports headers, implementation files, and snippets.
2. Use the slider beneath the editor to match your indent preference. The preview updates immediately.
3. Use “Clear” when you want to reset both editors for a fresh session.
4. Download or copy the cleaned result from the right panel and drop it into your IDE or code review.

Ideal scenarios

• Preparing snippets for documentation or technical blog posts.
• Cleaning up code pasted from email, Slack, or PDF manuals.
• Reviewing student submissions or code katas where formatting varies wildly.
• Clean up other languages too with the PHP Beautifier or Python Formatter when switching between projects.
