Tool Overview

This tool formats C/C++ code with indentation cleanup and sample loading for interview snippets, embedded work, code review, and pre-commit cleanup.

Key Features

  • Supports 2-space indentation and 4-space indentation.
  • Includes sample loading, result copy, and dual-panel comparison.
  • Works with common C and C++ snippets, class definitions, conditions, and loops.
  • Keeps processing in the browser without uploading code.

Steps

  1. Paste C or C++ code into the left panel.
  2. Pick the indent style you want.
  3. Run the formatter and copy the processed result.

Use Cases

  • Clean interview snippets and algorithm answers.
  • Normalize indentation before review or commit.
  • Tidy embedded development code and small utility fragments.

Notes

  • The tool does not compile or execute code and only processes text.
  • Review the result manually when the source relies on complex macros, conditional compilation, or custom alignment rules.
