C# Code Formatter & Beautifier: Core Features and Principles

When C# source code has messy indentation, random line breaks, and inconsistent spacing, reading and maintaining it becomes incredibly difficult. This tool automatically organizes code structure based on syntax parsing, standardizing indentation, line breaks, and spaces. It outputs neatly formatted and consistently styled C# code, easily achieving code beautification and improved readability.

Why Choose Our C# Code Formatter?

• Smart Indentation & Line Breaks: Automatically identifies code blocks such as classes, methods, and loops to apply consistent hierarchical indentation. Brace placement can be customized to the end of the line or the next line.
• Instant Results: No need to install a development environment. Simply paste your code to beautify it with one click and preview the results instantly.
• Preserves Semantics: Only adjusts whitespace characters. It does not change any logic, variable names, or comments, ensuring complete safety and reliability.

How to Use

1. Paste the C# code snippet you want to format into the input box.
2. Select your preferred indentation style (default is 4 spaces) and brace wrapping rules.
3. Click the "Format" button, and the beautified code will instantly appear on the right or below.
4. You can directly copy the result or download it as a .cs file.

Input Example:

using System;class Demo{static void Main(){Console.WriteLine("Hello");}}

Output Example (Default Style):

using System;

class Demo
{
    static void Main()
    {
        Console.WriteLine("Hello");
    }
}

Frequently Asked Questions (FAQ)

• Will formatting change my code's logic?
  No. The tool only processes indentation, line breaks, and extra spaces. It does not modify any identifiers, keywords, or code structures.
• Which C# versions are supported?
  It supports most common syntax from C# 1.0 to the latest versions, including LINQ, async methods, pattern matching, and more.

Important Notes

This tool is suitable for pure C# code snippets or complete files. However, please avoid inputting extremely large files exceeding 100,000 characters to prevent browser lag. Formatting results may vary slightly based on personal preferences, so we recommend previewing before doing a full replacement. We do not store or transmit your code; all processing is done locally in your browser to ensure complete privacy and security.

Technical Notes & Best Practices

For team collaboration, we recommend standardizing formatting configurations (such as indentation width and brace placement) before committing beautified code to your repository. This effectively reduces merge conflicts caused by formatting differences. For large-scale projects, it is advisable to use EditorConfig or an .editorconfig file in conjunction with your IDE. This tool serves as an excellent auxiliary utility for quickly adjusting the format of code snippets you plan to share externally.
