Formatting and beautifying code in Visual Studio IDE can greatly improve readability and consistency. A well-formatted codebase makes it easier to understand the code, debug issues, and collaborate with others. This comprehensive guide covers everything you need to know about code formatting in Visual Studio.

Introduction to Code Formatting
Code formatting refers to the proper indentation, spacing, and styling of code according to established conventions and standards. The main benefits of formatting code include:
- Readability – Well-formatted code is easier to read and understand for developers. It improves comprehension and productivity.
- Consistency – Applying consistent formatting creates uniformity across the codebase. This makes it easier to navigate and find code.
- Maintainability – Properly formatted code is easier to maintain and build upon in the future. It reduces errors and speeds up updates.
- Collaboration – A shared formatting scheme enables smoother collaboration between developers. The code looks familiar to every contributor.
Built-in Formatting in Visual Studio
Visual Studio provides several built-in formatting capabilities:
- Format Document – Formats the entire active code file. The keyboard shortcut is Ctrl + K, Ctrl + D on Windows and Linux or Shift + Option + F on Mac.
- Format Selection – Formats only the selected code. Use Ctrl + K, Ctrl + F on Windows and Linux or Command + K, Command + F on Mac.
These commands automatically format the code based on default style guidelines for languages like C#, JavaScript, TypeScript, and more.
You can access them through the main menu, context menu, or command palette. There are also options to run formatting automatically on paste, semicolon, bracket, etc.
Configuring Code Formatting Style
The default formatting style may not suit your preferences or project style guide. Visual Studio allows customizing formatting options through:
EditorConfig Files
Create an .editorconfig file to define formatting styles that override editor defaults. This is the recommended approach for consistency across different editors and IDEs.
Text Editor Options
Go to Tools > Options > Text Editor and choose your language to customize formatting rules related to indentation, spacing, newlines, wrapping, etc.
Top Extensions for Code Formatting
In addition to built-in features, Visual Studio extensions from the marketplace add more advanced formatting capabilities:
- Prettier – An extremely popular opinionated code formatter supporting multiple languages.
- ClangFormat – Applies LLVM coding style standards to C, C++, Objective-C, and more.
- CodeMaid – Cleans up code through a variety of configurable formatters and rules.
- Uncrustify – Focuses on formatting C, C++, C#, Objective-C, D, Java, and more based on configurable style options.
Make sure to set your preferred formatter as the default in Visual Studio for automatic application.
Formatting on Save
Manually formatting the entire document can be tedious. To streamline the process, you can enable formatting to trigger automatically when you save the file.
Per File Auto Format Setup
- Install Format Document on Save extension
- Right click on a code file > Select Format Document on Save
This will now format the given file on saving it. You can do this file-by-file.
Project-Wide Auto Format Setup
To enable format on save globally for a project:
- Go to Tools > Options > Text Editor
- Check the boxes – Auto format on paste and Format document on save
Now all code files in this project will apply formatting while saving.
Conclusion
Proper code formatting should be an essential practice to improve quality and consistency. Visual Studio gives full control through built-in features as well as extensions to customize formatting.
Auto-formatting on save eliminates tedious manual work once set up correctly. Teams should establish and share editor configurations to maintain a uniform structure across the codebase.
Consistently applying great formatting will make the code cleaner, easier to work with, and more professional.
