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

You can load NeoCSV using Metacello

Metacello new

You can use the following dependency from your own Metacello configuration or baseline
