Directly adding data in MYSQL tables made through drupal
Not sure but could you design your view fields [name, address, country] the way you want to use them. Then enter unique data.

Then look in the DB for the unique data to be sure you have the right fields.

After backup and site shut down you could import your csv right into mysql. With the db interface. Make sure you backup The tables before starting.

A bigger question perhaps is how will you work with the data.
