I'm looking for a way I could:
retrieve a list of all my contacts and their email's and
In order to retrieve a list of all of my contacts into a Google spreadsheet, I exported them as a Google CSV and then imported them into a new spreadsheet.
Determine if the contact is a Google account
Is there a function in the Google spreadsheet api that can determine if the contact is a Google account or not? getIM() is the only one I saw that might be able to do this.
