Why can't I create new categories using the Bulk Upload feature?
The Bulk Upload feature supports updating existing categories in your Quick Shopping Cart Product Catalog. We currently do not support creation of new categories using Bulk Upload.
To keep your spreadsheet current, we recommend that you export the latest copy of your catalog, especially if your categories or other items have been updated since the catalog was last exported. Begin with the latest export of your catalog before editing using the Bulk Upload feature.
