I have a CSV file which contains newline breaks within some of the fields. This needs reformatting into a format which is valid as input to the easypopulate script for OSCommerce. The input file contains multiple category columns which can be set to blank or YES. For each YES a full line will need writing to the easypopulate CSV file (i.e. there will be more output lines than input lines).
A full spec of input and output columns and reformatting will be provided.
