If you are able to download an Amazon Open Listings report, you can then upload that file to us. Your Amazon account must be a "Pro seller" account in order to have access to the Open Listings Report. You may wish to get in touch with bookseller support at that site about your options for downloading a file containing your active listings. Please note also that any file uploaded to Biblio must contain at least these five required fields:
1) inventory number or SKU
2) title
3) author
4) condition/description
5) price
You can download the same report from Amazon and upload it to Biblio on a regular basis, as a purge and replace file, to make sure everything is up to date.
Please contact bookseller-support@biblio.com with any questions or concerns and we'll be happy to help!
