re: Perhaps I should use another Char for delimiter then Comma, since there are some in my adresse fields (in French, address are formated as such “Civic numer COMMA Street name”)…
If the field values are not quoted, then yes, the comma in the road name can mess up the import.
YOu should still be able to use a comma, just make sure all the field values are quoted in the CSV file.
If you’re using Excel … that app creates poor CSV files. I suggest using LibreOffice.
