CSV = Comma Separated Values
If you export to CSV you'll get a text file with a whole bunch of lines, and it'll have all of the values separated by commas, it might look something like this:
Timmy Jones,11,12/14/1984,555-1212,123 Main Street
Jessica Smith,10,09/22/1985,222-2222,4321 Grand Blvd
...
And so on, I'm sure you can get that into mySQL easy enough.
