Yes, you can import easily CSV events. In this document you have details on the format for the CSV file:

thanks, is there a demo-version where i can test it?

You can download JEvents for free from https://www.jevents.net/download-area/jevents then if you want you have the option to join the club at a later date if you want to use some of the addons we offer.

okay. one last question: can i add custom fields?

hey sorry.
add custom fields are in the silver version - i see

but whats important for me: when i import an csv-file with events, can i also import the infos for the custom fields?
for example: i create an custom field with the name "car"
and in my csv-file i have one columt with "car", so that colum should also imported to every event.

i actually cant test it in the free version, because these features are only in silver and gold edition...

Yes, Custom Fields are imported in the CSV field. For instance for your "car" custom field, you just need to create a column named "car" and place there your values for that custom field.
