Yeah CSV is easy to export, because its not really a file format, but more an idea. I'm not even sure there is such a thing as "invalid" CSV

The following are all valid CSV, and they should all mean the same thing, depending on your point of view:

1) foo, bar, foobar

2) "foo", "bar", "foobar"

3) "foo", bar, foobar

4) foo; bar; "foobar"

5) foo<TAB>bar<TAB>"foobar"

5) foo<EOL> bar<EOL foobar<EOL>

Have fun writing that parser!
