Unquoted input should look like this:
unquoted input: 0,10,Text,123
Note the absence of spaces as well. Not sure what flavour of CSV you are using, but there usually aren't spaces after the delimiter.
unquoted input: 0,10,"Text,","123" output: (Num) 0 (Num) 10 (Text) Text, (Text) 123 quoted input: "0","10","Text,","123" output: (Num) 0 (Num) 10 (Text) Text, (Num) 123
