What is a CSX file?
The .CSX extension is most commonly used for Visual C# Script files created for the Microsoft .NET ecosystem. These files contain executable C# code used for scripting and automation. Developers often run them using the Roslyn compiler.
However, .CSX files can also store other types of data. They are used as Cotopha image files by Entis, contact synchronization data by CompanionLink Software, CourtSmart XML session files, and Cheat Engine structure files. They also function as index files for Hikvision CCTV cameras and synthesizer presets for the Arturia CS-80 V.
How to open CSX files?
Because .CSX files have multiple possible meanings, you need to know the specific format to open them correctly. Visual C# Script files can be opened in text editors like Visual Studio Code or Notepad++. Camera index files require video management software like Genetec Security Center.
Inspecting unknown CSX files
If you do not know the origin of your file, viewer.online/csx can analyze .CSX files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and conversion
If you need to change your .CSX file to another format, you can convert it to sensible target formats on convert.guru. For example, scripts can be saved as standard .CS files or .TXT files, while XML sessions can be converted to standard .XML.
Summary
Using viewer.online/csx is useful for identifying, inspecting, and understanding .CSX files without installing software or dealing with compatibility problems.
