Fix createCSVData on Windows

The csv module documentation says to open the file with newline='':
https://docs.python.org/3/library/csv.html#id4

Also, I'm pretty sure this isn't how you are supposed to use csv.writer.
delimiter='\n' doesn't seem right.
We should either let the csv writer actually generate the rows, or
remove it altogether and just write the string rows into the file.
