It should be possible to export events via your dashboard… so I guess it’s also possible to import them. To be honest, have never tried this. Maybe I will try this weekend, in my test enviroment.
Thank you for your answer. I don’t understand what you mean by the import/export function.
how do I prepare/edit the data and how do I add it to the vsel plugin?
Guess you’ve heard of the native import/export feature in your site’s dashboard > Tools? That’s how you can import/export the content of your site, or only certain type of posts (such as events). That’s how I did it.
