What are you talking about? Excel opens csv with zero issue. In windows, and mac. Mac you right click and "open with". Or you open excel, and click file/open and find the csv. I do the first one a dozen times a day.

Only if the Windows Regional Settings List Separators happens to be "comma", which is not the case in most of Europe (even in regions that use the decimal point) so only CSV files with SEP=, as the first line work reliably with Excel.

		Literally did this all day today. Took a csv file, parsed it in elixir, processed it and created a new csv file, then opened that in excel, to confirm the changes. At least 100 times today.

		This, plus the parser in Excel gets thrown off by some multiline edge cases very easily. Also, the file has to be UTF-8-BOM, not just UTF-8.
