I’ve created a little snippet to Export a CSV with customers data that you can easily import to Google CSV Export Client to Google Contacts following the actual Google Template to Map fields that you can see on the topic here Import your contacts into Google Contacts - Computer - Contacts Help
I’m just mapping these but you add whatever you need to the file:
‘First Name’, ‘Last Name’
‘E-mail 1 - Label’, ‘E-mail 1 - Value’
‘Phone 1 - Label’, ‘Phone 1 - Value’
‘Phone 2 - Label’
‘Phone 2 - Value’
‘Address 1 - Label’
‘Address 1 - Country’
‘Address 1 - Street’
‘Address 1 - Extended Address’
‘Address 1 - City’
‘Address 1 - Region’
‘Address 1 - Postal Code’
‘Address 1 - PO Box’
‘Organization Name’
‘Website 1 - Label’
‘Website 1 - Value’
