The events-manager wordpress plugin is hard to export data from.
This takes all its data, and gives you a CSV file you can export into google sheets.
You also need to run this formula to import to a new sheet and fix stuff:
=ARRAYFORMULA(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(raw!A1:AJ14022,"YAR77D",CHAR(10)),"YAR77C",","),"YAR77B",""""),"YAR77A","'"))
or something like that
