There is no way to access bulk event data outside of direct database access

Add a download to spreadsheet feature for event data

[grioux-neo]

There is currently an event export to spreadsheet feature, but it only exports partial event data (no POCs, no custom attendance fields) and it only exports the events displayed in the event list (limited to the past year or so)
