Many product fields can contain multiple records. For example the Product Specifics, Upsell, Cross Sell and Related Categories fields can contain multiple records in each. For such fields, multiple records are imported as either comma separated
(,) or semi-colon separated
(;) lists. The separator used is dependent on the field type (refer to field list at the end of this document for details).
To upload a list of Upsells to a product, you can insert a comma separated list of Upsell SKUs into a single field and import to the “Upsell” field:
PDB123, SKO54, OUJ746, FRG830
