Experts,

Client wants to import customer and sales data from their online store. The download is in CSV format. The format is displayed as such:
Sales Date
Order Date
Buyer User ID
Full name
First Name
Last Name
Street 1 etc etc etc

HOw can I write the code to skip certain headers/data: For example i i only want to import the First Name and Last name. How do I programmatically certain colunms in the CSV? I dont want to tell the client to modify the downloaded CSV file.
