Extract text from C# script files (CSX)
To convert CSX scripts to another format, you need Microsoft .NET or other Developer software.
To convert other file formats to the "Script and Data File" file type, you need software like Microsoft .NET or a similar tool.
The .CSX file extension is heavily fragmented and shared across entirely different software ecosystems. Its most widely recognized use is as a Visual C# Script file, executed by the Microsoft Roslyn compiler or the .NET framework. Game modders frequently encounter these scripts when using software like UndertaleModTool. However, the extension is also used to store Cotopha images by Entis, XML session data for CourtSmart legal recording systems, camera recording indexes for Hikvision or Genetec Security Center CCTV systems, contact synchronization databases for CompanionLink, and even ZIP-compressed synthesizer presets for the Arturia CS-80 V.
Because the .CSX extension is dangerously overloaded, opening these files is a frustrating guessing game. Double-clicking a .CSX file usually forces the operating system to launch the wrong application. If the file is a C# script, it remains readable text but lacks the compiled execution context of a standard program. If the file is a Cotopha image, Hikvision index, or CourtSmart archive, it is completely unreadable without the exact legacy or proprietary software that created it. These proprietary formats trap your data, making it impossible to preview in a standard web browser or share with colleagues without forcing them to buy expensive software licenses.
The only practical solution is to convert the file into a universally supported standard based on its internal contents. For scripts, convert to standard TXT or CS for seamless editing. For Cotopha images, convert to PNG or WebP for immediate web compatibility. For CourtSmart XML data, convert to standard .PDF/A for permanent archiving.

Convert.Guru analyzes your CSX file, detects the exact format, and lets you read the text inside.
Users also converted CXS, XCS, CSV, XLS, PNG, VBS, JSE and VBSCRIPT files.
If you want to convert CSX file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Microsoft .NET or similar software from the "C# Script or App Data" 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 CSX, try Microsoft .NET or another comparable tool in the "C# Script or App Data" category.
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 CSX converter.
