Answer 1

I found a way to parse this malformed CSV. I looked for a pattern and found it.... I first replace (",") with a character... like "¤" and then split it...

from this:

"Annoying","CSV File","poop@mypants.com",1999,01-20-2001,"oh,boy",01-20-2001,"yeah baby","yeah!"

to this:

"Annoying¤CSV File¤poop@mypants.com",1999,01-20-2001,"oh,boy",01-20-2001,"yeah baby¤yeah!"

then split it:

ArrayA[0]: "Annoying //this value will be trimmed by replace("\"","") same as the array[4]
ArrayA[1]: CSV File
ArrayA[2]: poop@mypants.com",1999,01-20-2001,"oh,boy",01-20-2001,"yeah baby
ArrayA[3]: yeah!"

after splitting it, I will replace strings from ArrayA[2] ", and ," with ¤ and then split it again

from this

ArrayA[2]: poop@mypants.com",1999,01-20-2001,"oh,boy",01-20-2001,"yeah baby

to this

ArrayA[2]: poop@mypants.com¤1999,01-20-2001¤oh,boy¤01-20-2001¤yeah baby

then split it again and would turn to this

ArrayB[0]: poop@mypants.com
ArrayB[1]: 1999,01-20-2001
ArrayB[2]: oh,boy
ArrayB[3]: 01-20-2001
ArrayB[4]: yeah baby

and lastly... I'll split the Year only and the date from ArrayB[1] with , to ArrayC

It's tedious but there's no other way to do it...
