You need to first unzip the downloaded file, it is in a compressed format from probably WinZip. After you extract the file from the zip, you can open that file with Excel.
Hope this answers your question.

it has been a long time since anyone posted on this thread... I can't get this file to open either and the last post (in 2007) was having the same problem. Is this file still valid?
something is wrong with the way the file is getting uploaded. When I compress the file into a .zip file I can open it.
When I upload it here, it appears to be the same size. But when I open it, I get a invalid archive msg. So, what I have done for right now is to upload the file with a .txt extension.
To use the file, you will need to rename it with a .xls extension.
