A chapter in the Enterprise Pharo book is a good introduction to NeoCSV.

Go ahead and read the NeoCSV paper.

Basically, NeoCSV deals with a format that

• is text based (ASCII, Latin1, Unicode)
• consists of records, 1 per line (any line ending convention)
• where records consist of fields separated by a delimiter (comma, tab, semicolon)
• where every record has the same number of fields
• where fields can be quoted should they contain separators or line endings
