The list of attendees of an event can be pulled up from your jumper dashboard.
This can be done as Orders -> Events 

                                                                   

In this section all the orders for the events module would be visible. This would display the attendees name, order ID, payment mode, quantity, payment status and amount. 



The entire list of attendees can be obtained by downloading the CSV file. This can be done hitting the 'Download CSV' button as shown in screenshot.
