Dear Luis,
For now, the SDK does not include a language wrapper for Excel/VBA. This is something we would like to add to the SDK, but we do not have the funds to do so at the moment.
The reason we have not included an Excel/VBA wrapper is that Excel/VBA uses the stdcall calling convention, while SAM (and most other languages) use cdecl. If you have programming experience and knowledge of calling conventions, you could write your own wrapper around the cdecl SSC API to make it appear as an stdcall API.
Best regards,
Paul.
