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.

Saving out and reading in CSV is simple for Numbers. (And perchance you should wonder, the autocorrect runs from the system service, so turning that off will disable that as well for you.)
