To make an export of all your profiles go to profiles > All profiles. Then you'll see a big button at the top right of your screen that says 'export profiles':

Select the desired filters, enter your email address and click 'email export'. You will then receive the export as a .CSV file in your mail.

The export that you make here is based on the chosen language. Does your web shop have multiple languages? Then you also need to make multiple exports (of English, Dutch, German etc.)
