The easiest way to export all your contacts to another program is to first download your contact list to a CSV file. CSV files are commonly used for uploading data and most programs allow imports through this file format.
Follow the steps below to export your entire contact list to a CSV file.
1) In the menu go to Contacts>View All
2) Scroll to the bottom of the page
3) Click the "Export all contacts to CSV"
4) Click "Send CSV"
If you wish to export only a specific portion of your contact list you can filter your list by "Type", "Source", "Tags", and "Person or Company". Do this between steps 1 and 2 above.
Once step 4 is complete the file will be sent to the user's email address. Please note that this may take a few minutes as the CSV file needs to be generated first.
