Not everyone can be expected to have these two different spreadsheet programs on their computer so this solution is not going to be much use to friends who want to use my project for themselves. I really need to embed some EXCEL cells, but cant find any reference to such a procedure.
Consider to use the spreadsheet-component which is part of the Office Web-components. You can download the latest version here:

Let us know what You think of this approach,

Kind regards,
