The fsx file extension is associated with Microsoft Visual F# (F SHarp) development software.

F# is a programming language that provides support for functional programming in addition to traditional object-oriented and imperative (procedural) programming. The Visual F# product provides support for developing F# applications and extending other .NET Framework applications by using F# code. F# is a first-class member of the .NET Framework languages and retains a strong resemblance to the ML family of functional languages.

The fsx files are similar to the *.fs source code files created in this language with few extra capabilities.

The .fssscript files are meant to be run with the "F# Interactive" mode in Visual Studio. They are used for executing scripted F# code rather than compiling it into a .dll or .exe file.

Sometimes the FSSCRIPT file extension is used for the F# scripts instead.

How to convert:

As far as we know, this .fsx file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
