yes exactly,i want csv filter column to pic values from array.
and i have a string -name,age,country
i want this string to convert into array and pass top the csv filters column .
This came up just a few days ago (unfortunately I can't find the old thread) but the conclusion was that there wasn't a simple way of doing this. The easiest way out might be to use the ruby filter both for finding the column names and doing the CSV parsing itself.
Finally got what i wanted 
thankyou so much magnus for your support
