Your best bet would have to link to an external source, like an Excel spreadsheet hosted on your website:
Code:
Download <a href="www.example.com/spreadsheet1.1.xslx">Spreadsheet 1.1</a> and try the samples.
Then someone using a computer could click the link, download the spreadsheet, and work from there.
Note: While there are ways to insert "Miscellaneous" files (DOCX, XSLX, [...]) into an EPUB, I have no idea how stores/validators would treat such an EPUB.
I know iBooks has support for embedding a PDF into an EPUB (see
PDFs heading):
https://help.apple.com/itc/booksasse...oj/static.html
How reliable this would be on all the other EPUB readers...

And I doubt it would handle any non-PDF formats.
Note #2: Back in 2011, there was
some discussion of embedding PDFs into an EPUB.
And phyllisj9 linked to the actual section of the EPUB2 specs dealing with this:
http://www.idpf.org/epub/20/spec/OPF...Section2.3.1.1
Again, any actual readers out there or stores that support this for spreadsheets... I doubt it.
Note #3: What you are more likely looking for is attaching documents to a PDF:

PDF is more of the "make it possible to do everything under the kitchen sink and be a security nightmare" format.

And even there, many spam filters might try to protect from malicious PDFs with embedded attachments in them.
