How do you create a row in export formula?

I understand that adding a comma will create a new column but I want to start a new row.

The system will always automatically put one item or part on a single line, but if you add headers to the export location, and then a header to the product itself (at the bottom of the attributes tab of a product) each of those will have their own line, giving you a bit more organization. Maybe if you let me know exactly what you're trying to do I can give you more guidance!
