"Quantity not available in Tape & Reel" errors when uploading a list of components in xlsx format


I am trying to upload a .xlsx file with the manufacturer’s part number and quantities but some items were not added to my order because of errors, precisely “Quantity not available in Tape & Reel” and “Duplicate manufacturer part, please use part search feature or contact Digi-Key” errors.

How can I get around these errors because the list is fairly extensive and I cant get just fix one item by one (by choosing cut tape) ?
Or maybe if there is a tool to get Digi-Key Part Number from the manufacturer’s part number it could help.

Thank you,
