CSV to PLIST conversion Issue

I am trying to convert a csv file into plist but I am quiet unsuccessful in doing that.
my csv file looks like:

pro1 |
 add 1| add 2
 bb     4
 cc     5
 pro2 |
 add 1| add 2
 ee     5
 cc     8
 qq     10
 ww     9
 ee     4
 tt     7
 pro3 |
 add 1| add 2
 gg     2
 hh     1
 qq     11
 oo     19
 

I am thinking of how to make a separate array for every pro?
