If you live in a place where comma is the decimal separator, your CSV files will often use semicolon as the separator instead of comma. Will this tool cater for that?
Have you maybe lost track of what post you're commenting under?
(I believe the answer is no BTW, the tool only supports , as delimiter in its input.)
If I work with CSV files they are most often not comma-separated but semicolon-separated because of the numbers. An Excel installation localized for decimal comma would not read 'real' CSV files correct.
If csv-to-usv cannot cater for this type of CSV files, it would not be usable in a large part of the world.
