The sll file extension is associated with the Static link libraries. A sll file is a set of routines, external functions and variables which are resolved in a caller at compile-time and copied into a target application by a compiler, linker, or binder, producing an object file and a stand-alone executable.
This executable and the process of compiling it are both known as a static build of the program. It is still used during the compile process by some compilers. Used in MS-DOS and Microsoft Windows 3.x.

Microsoft Office Web Components is Microsoft technology for embedding and publishing spreadsheet, chart, and database components through Web pages. The components use COM controls to provide this functionality on Microsoft Windows.
An SLL file is a supporting spreadsheet load library for Office Web Components. It is a software resource used by the components rather than a spreadsheet document intended for editing, and it belongs with the related Office Web Components installation.
Office Web Components is legacy Microsoft Windows software and is not part of current Microsoft Office installations. An SLL file may therefore be encountered with older applications or Web projects that depend on this technology.
An SLL file is not normally opened directly. On Microsoft Windows, it is used by a compatible installation of Microsoft Office Web Components and should remain in the location required by that software.
It does not function as a standalone spreadsheet. To view or edit the related data, use the original Office document or the older application or Web project that uses the component.
An SLL file is a software library, not a spreadsheet or other user document, so it has no useful direct conversion to a common document format.
If spreadsheet data is needed, open the original spreadsheet or the application that uses Office Web Components and export the data from there.
