Hi Matt,
Many of our users use WP All Export, which provides a lot of flexibility in what you export and allows you to export to .csv or .xml.
We do have a page where you can view all attendees for a particular event, and we also have an extension that allows you to view all registrations on a single page. This article has some more details on managing attendees and the check-in process.
We do have a great 30-day full refund policy, so if things really don’t work out the way you’d hoped, you can get a full refund.
Also, feel free to check out our demo site here.
Let me know if you have any other questions!
Thanks,
Jaime
