I have been having issues importing a csv into arena. Are there required columns? Is there a certain csv format that I need? Is there anything else I need to be aware of when importing in people from a csv?
If it helps I am always getting this error for each of the people I am trying to import. "Object reference not set to an instance of an object"
I believe if you click on the gear to show the module settings, you'll see all the default column headers, as well as the option to change them.
Also, if you contact support we can provide you with the import template we have so you can compare the csv to what you are using
