About this tool

Paste C# code and format classes, records, methods, expressions, LINQ queries and modern language constructs with a CSharpier-compatible engine backed by Roslyn. Configure line width, indentation and tabs.

C# requires more than bracket indentation: directives, attributes, pattern matching, interpolated strings and contextual keywords all need the real grammar. The formatter therefore loads a .NET WebAssembly engine instead of trying to imitate C# with regular expressions.

The engine runs in the browser. Its larger runtime is downloaded only on this page, and source code is not uploaded.

Good to know

Questions people actually ask

Is this a real C# parser?
Yes. The tool uses a CSharpier-compatible Roslyn engine, not regular expressions or a generic indentation algorithm.
Is the source code uploaded?
No. Parsing and formatting run in the browser. The language engine is loaded on demand and the source stays on the device.
Can formatting change program behaviour?
The formatter is designed to preserve the parsed program while normalising line width and indentation. Review a diff before committing, especially when a repository enforces different style rules.
