Convert C# to Markdown.
Drop a .cs file and get Markdown that wraps the source in a fenced csharp block, byte for byte. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files

Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Source that
reads anywhere.
A .cs file is plain text, but pasting it straight into a note or a chat box loses its indentation and runs lines together. Converting drops the whole file into a fenced csharp block that keeps every line exact, ready for docs, pull requests and LLM prompts.
class Program {
static void Main() {
System.Console.WriteLine("Hello");
}
}
```csharp
class Program {
static void Main() {
System.Console.WriteLine("Hello");
}
}
```
Everything you
actually need.
A C# file in, a clean fenced block out, with no server and no account anywhere.
It never leaves your browser
Your .cs file is read on your own device. Nothing is uploaded to any server, ever.
# Heading
- point one
3 chunks
AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
```csharp
Console.WriteLine("hi");
```
Code, preserved
The source is kept verbatim in a fenced csharp block, so braces, semicolons and indentation all stay exactly where you wrote them.
Unicode safe
Accents in string literals, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
Nothing is
lost.
Honest about what comes through, and what stays put. These are the same notes the Formats list shows for C#, so the page never drifts from what the converter really does.
Kept
2- Every line of source, byte for byte
- A fenced block tagged csharp
Preserved
2- using directives and namespaces
- Comments, attributes and unicode
using System;
Console.WriteLine("Hello");
// summary comment
[Obsolete]
C# questions,
answered.
Everything worth knowing before you drop in a .cs file.
