All of your registration information can be exported to CSV to allow you to use that information however needed.
To export your registrations go to Event Espresso -> Events.
Hover over the event name you wish to export the registrations for and click the ‘Registrations’ link that appears.
You’ll be taken to a table of registrations specifically for that event, at the bottom of the table is the ‘All Registrations CSV Report’ button:
Clicking that button will download a CSV of all the registrations for that event.
You can also export the attendees based on the filters at the top of the Registration page, or the Check-in tab. You can filter by date (month/year), category, status and event and datetime.
You can then export that filtered list of attendees by clicking the “Filtered CSV Report” button at the bottom of the page.
