No, they cannot.

you cannot. JPEG, PDF files can be easily viewed without downloaded any additional plugins

You absolutely can view excel files. Like the previous poster said, you need to email them to yourself as an attachment, but you can open them up and view them. You can not edit them in any way, though.

sorry, unknown to me, and it doesn't work on mine when someone emails .xls! share if there is any tweaks needs to make it to work..
thanks.

thanks a lot! learning something everyday! great stuff.

There are actually two ways to view Excels. One is to Mail it to yourself, as people have said here. The other is to use a cracking bit of Freeware that sits on your Mac called File Mark Marker

You drop the file onto this application ( It supports .doc, .xls, .rtf, .txt, .jpg, .jpeg, .png, .gif, .pdf, or .html) and the app encodes the data into a bookmark that you sync to your iPod. Bottom line - your file can then be opened in Safari.

To be clear - you don't have to have to be online - the data is held within the bookmark. Yes it's a bit of a hack, but it works just fine. Make sure the filename is fairly short though, that can muck things up sometime.
