Who it is for

Sellers, agencies, catalog teams, and agents preparing a cross-listing worksheet before checking the current category template in each authorized account.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday treats every supplied field name and value as untrusted data and only carries the value into a planning draft. The fixed crosswalk uses human-readable common labels, not current upload columns, API properties, taxonomy, required attributes, or allowed values. It accesses no seller account, does not publish listings, and does not create, change, or upload a listing. Confirm every target field and value in the current category-specific marketplace workflow before use.
