How to use

Why use this tool

• Defaults match the Microsoft / Visual Studio style: Allman braces, 4-space indent.
• Tidies common shorthand: auto-properties and expression-bodied members.

• For full Roslyn-level format use <code class="rounded bg-slate-100 px-1 text-xs dark:bg-slate-800">dotnet format</code> locally.

Frequently asked questions

What is C# Formatter?

A C# Formatter is a tool that reindents C# source code in the browser using Allman braces, with auto-property normalization and expression-bodied member tidy-up. It works as an indentation tidier rather than a full Roslyn-based formatter, applying consistent layout to code while keeping the source on the user's device.
