About CS files
A .CS file is a plain text file containing source code written in the C# (C-Sharp) programming language. Developed by Microsoft, this format is the foundation of the Microsoft .NET Framework and is widely used for building desktop software, web applications, and scripts for the Unity game engine. Additionally, the .CS extension is used by the CLEO Library for Grand Theft Auto custom scripts and by the NinjaTrader platform for algorithmic trading indicators.
The primary disadvantage of a raw .CS file is that it cannot execute on its own. The code must be compiled into a binary format, like an EXE or DLL, using the C# compiler. Furthermore, sharing .CS files with clients or non-developers is problematic. Without a dedicated IDE, reading the unformatted code is difficult, and most email clients block .CS attachments outright due to strict security filters targeting executable scripts.
To share code safely and maintain readability, conversion is highly recommended. Convert your .CS to PDF to lock in formatting for code reviews or archiving. For web display, convert to HTML to retain syntax highlighting. If you just need to bypass email filters, convert it to a standard TXT.
Convert.Guru analyzes your CS file, detects the exact format, and lets you read the text inside.
If you want to convert CS file to VB, PDF, DLL, S, PYTHON, JSON, JAVA, JS, TS, PY, CPP or C, you can use Microsoft Visual Studio or similar software from the "C# Source Code Storage" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to CS, try Microsoft Visual Studio or another comparable tool in the "C# Source Code Storage" category.
The CS Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CS converter.
