Other than starting with Model No -
1. are there other required fields (as in can I leave some out of the spreadsheet)
2. is there a "mandatory" order for the fields with information to be uploaded

Thank you for any help you may be able to offer.

P.S. we have successfully added the filed for UPC code but there are some others unique to most product lines we would like to include and a csv file with fewer columns would be much less cumberson
