The spkg file extension is associated with Sage, an open-source mathematics system formerly known as the System for Algebra and Geometry Experimentation. Sage runs on Linux and is also available for Microsoft Windows.
A Sage package can contain third-party software or mathematical libraries, together with source files, patches, and Sage-specific build or installation instructions. Sage uses these archives as part of its package and build system.
An spkg file is not normally opened as a document. Use the Sage package tools to install or process it, for example by supplying the package file to Sage's package installation command.
On Microsoft Windows, open the file from the command line provided by the installed Sage environment. A general archive program may be able to list its contents, but it will not build or install the Sage package correctly.
An spkg file is a software package archive, so it has no useful document-conversion target. Sage can install or unpack the package, but converting it to another format does not preserve its Sage package functions.
