You can simply upload the workbook with your summary sheet to Google Docs as
an spreadsheet.

Hello,

I am looking for a way to use Excel, VBA or some sort of Google API
to update a Google spreadsheet. Here is a little more of an
explanation. I have a budget for me and my wife that I would like to
share online for easy reference. A lot of its functionality is via
VBA so I must use Excel, but I would like to post a summary sheet that
both of us can see. I think that Google Spreadsheets would be an
optimal way to do this, but I just don't know how. Any comments/
thoughts/ideas?
