How do you add the barcodes to a sheet to scan?


I see all kinds of articles on how to use a barcode. I think I am good there but I cannot find out how to add the barcode in the first place so the infomration will be linked? We use GTIN Government issued barcodes for items we need to track and reference so I have the image, style, etc, just need to know how to enter them into a sheet?

Also could use them to point to reports or dashboards so how to I create new ones inside smartsheet?

Thank You
