Importing data for advanced custom fields plugin?

Question

I have a member section built using the http://www.advancedcustomfields.com plugin. There are 300 members that each have the following data:

• Company name
• Specialism (check boxes)
• Web address
• Telephone number
• Region
• Address
• Email

What's the best way to import into the database? How should I setup a csv file? I haven't added the 300 member pages, I just have these custom fields setup using the plugin.
