How do I dynamically adjust to CSV format?

Greetings, I get data in CSV files from several different sites and I can't get the date/time formats to be consistent, let alone have the fields arranged in the same order. I can put in the field/column names by hand in a first record but I can't find hoe to go about using them to change m
