Yes. You can upload csv files with more than one column, there is a facility to MAP columns( if you upload a file with ZIP/Postal Code, FirstName, LastName, Phone, Email Address then the validated file contains all these uploaded columns data along with validation info.)
Does it matter if my CSV file has a header row or not?
It does not matter, but all of our results include a header row that identifies the data points in each column. Some customers want the rows in their source file to sync up perfectly with the result file rows, so if this is you, you SHOULD have a header row in your source file.
