I use a csv file to import customers into Magento.
This is the csv file header :
website, email, group_id, group, firstname, lastname, password_hash, billing_firstname, billing_lastname, billing_company, billing_street1, billing_street2, billing_city,billing_region, billing_country, billing_postcode, billing_telephone,billing_fax, shipping_firstname, shipping_lastname, shipping_company, shipping_street1, shipping_street2, shipping_city, shipping_region, shipping_country, shipping_postcode, shipping_telephone, shipping_fax, created_in, is_subscribed
But if the customer have more than 1 billing / shipping address, which modification have I to do on the header ?
