Kevin,
Thanks for reaching out to us! I’d be happy to answer your question.
Using our Events Tickets plugin, you can export a CSV file of Attendees of a specific event. The Events Tickets Plus plugin allows you to create custom fields for the attendees, which is then included in the attendee export. This could certainly be imported as a Google spreadsheet.
You can read more about Events Tickets Plus here: https://theeventscalendar.com/product/wordpress-event-tickets-plus/
Let me know if that helps, or if you have any other questions.
Thanks,
Sky
