Apache Commons CSV

Have you seen Apache Commons CSV?

Caveat On Using `split`

Bear in mind is that split only returns a view of the data, meaning that the original line object is not eligible for garbage collection whilst there is a reference to any of its views. Perhaps making a defensive copy will help? (Java bug report)

It also is not reliable in grouping escaped CSV columns containing commas

FastCSV can be used as a drop-in replacement for CSV (replace CSV with FastCSV) except: The :row_sep option is ignored. The default :auto is implemented #9. The :col_sep option must be a single-byte string, like the default , #8. Python and PHP support single-byte delimiters only, as do the major libraries in JavaScript, Java, C, Objective-C and Perl.
