I have data like, below and when reading as CSV, I don't want to consider comma when its within the quotes even if the quotes are not immediate to the separator (like record #2). 1 and 3 records are good if we use separator, but failing on 2nd record

Input:

col1, col2, col3

a, b, c

a, b1 "b2, b3" b4, c

"a1, a2", b, c

Output:
