Tux seems to be offline, so I'll link to Text::CSV_XS:

• Text::CSV_XS takes care of reading and writing CSV files. Unlike most "five lines of perl" attempts, it handles most, if not all, nasty edge cases.
• DBD::CSV sits on top of Text::CSV_XS and allows SQL access to CSV files. It may be slower than SQLite proposed by locked_user sundialsvc4, but avoids converting CSV to SQLite.
