Bulk list and manage sales using flat files
eBay File Exchange is an end-to-end selling tool that enables high-volume sellers to list multiple items on eBay in a single file. File Exchange is a great tool for sellers to easily transfer their files from their computer to eBay. Sellers can list items using flat files from an Excel spreadsheet, MS Access, or other inventory software.
I believe this is only for managing your own listings. You want to scape data from listings.
