This works fine for me, both from an email attachment and Dropbox. I'm on 6.0.1. Maybe it's specific to certain features, or versions of .xls?
Why should the users have to resort to using a 3rd party app when the phone already has the technology built in?
If the phone didn't have the technology and a 3rd party app steps in to better the phone, that's fine with me. But the iPhone does have that technology, it's just that Apple decided to lock the file transferring capability of bluetooth in order to force its users to continue to use iTunes as the only way to transfer files.
