I'm with you on this one all the way.
The reason? My practical experience is that spreadsheets are the most preferred data cleaning platform out there. From novices to advanced computer users I consistently see people either keep their contacts data in spreadsheets or downloading to CSV in order to do cleanups and then replacement uploads. Usually the workaround is to get a (safe) third-party app to do the conversion but if the technology exists, maybe fruux can do it on a built-in basis.
It sounds like the key thing is for fruux to define for its users the target format. But the cool thing is that if a template is created and made available by fruux, I'm sure the rest of us would be happy map our own spreadsheets/CSV files to match.
