To export the attendee list for your event, select the event of your choice from your my events page to open its dashboard (note that you need to be logged in to access this page). Go to the "Orders" panel to access the order of your choice and press "Export" at the bottom of the panel.
The download of the list will begin once you have chosen its destination folder on your device.
The file lists all tickets sold independently (even if purchased with the same order) to allow you to manually check them at the door if need be. The list is formatted in a CSV file and can be read with any spreadsheet reader software such as Microsoft Excel or free alternatives such as Libre Office or Apache Open Office.
