| Unfortunately, Excel spreadsheets are not one of the filetypes that can be attached.
If you can do a screen capture and get the file to be under 50kb, then you can attach the image by clicking the "Go Advanced" button below. That will display a screen where you can see the option to manage attachments (that's where you'll upload the file.)
Good luck -- I love me a great spreadsheet!

PS - if you have the ability to create PDF files, you can do that as long as it's under the file size limit.
