Hi Tony,
It seems very difficult to transfer the CSV file from the WordPress calendar to a CSV file that can be imported by JEvents.
Of the 950 lines in the CSV there are about 80 lines that give problems. The point is that the action Text to Columns in Excel creates the right columns, except the fields that contain the description of the events and specially where there are several commas in the text of the descriptions.
So, I will have to add 950 events to the JEvents Calendar manually
Anyway, thank you for your kind help so far!
Kind regards, Edze de Boer
