Can Numbers save a file as CSV? I'm trying to switch over from Excel to Numbers. Is it possible to save a file as a CSV in Numbers?

The whole idea behind this is I prefer to have my documents on the cloud as well as on Numbers for my iPad and iPhone. I do not do typical data sheets, I manage database files so I do not need any features, I just need to be able to work with CSV files.
Yes, Numbers can export CSV files.

Go to File » Export and click the CSV tab.
