OTOH, I do use the free ASAP utility for Excel that includes an Excel to HTML routine that really works. Unless you're on a Mac you should give it try and see how it looks in FR's HTML sandbox. The results are pretty much one to one with what you see in Excel and the links (if you have any) are live. That's a big advantage if you need to include links that are built into the spreadsheet. I don't know any other way to do it.
Note that ASAP Utilities is free to use for Home users, Students and Charitable Organizations. You only need to buy it if you are a business.
I use Office 2010. It outputs everything real nice.
