All of the spreadsheets found on the web page are in Microsoft Word 97 or Microsoft Excel 97.
I believe that the reason it usually comes up in gibberish is that your browser doesn't know how to handle a .doc file or a .xls file.
There are two ways to fix this in my opinion. There is an easy way, which is more of a work-around, and there is a hard way, which I would think of as the correct way.
The easy way is to do a right-click on the link that you want to view, and then pick "Save Target As...". At this point, save the document to your hard drive and then open it using MS Word or Excel (or any other program that reads these files) the way you would open any other document on your hard drive.
The harder way isn't that much harder at all, but keep in mind that if you mess up your computer doing it, I cannot be responsible. I have Windows 98 and have written the directions for it. I believe the process is similar but not exactly the same for Windows 95, but I have no idea what it's like for Windows Me or Windows 2000.
Go to "My Computer", then to "Folder options", then to "File Types". Click on New Type". Put whatever you want in "Description of type" - this is a field for your information (I would put something like "MS Excel" in there). In associated extension, put "XLS" in there. If you get an error at this point then click ok and the cancel - these directions won't work for you.
If you are still with me, then click "New", then type "Open" in the action field and the the "Application used to perform action" field, hit browse and then find excel.exe. My excel.exe is in C:\Program Files\Microsoft Office\Office\excel.exe - yours may be elsewhere. Then hit ok - we're done!
If you've tried the hard way, please email me. I'd like to know if it worked for you or not, or if you had any problems with it.
