Fictional editorial exercise. Keep inputs separate from reference answers. Downloads do not establish accepted business results.

Open Amazon Listing -> Official template preparation. Load source.csv, review SKU/title mappings and confirm data. In Official workbook mapping upload template.xlsx. Choose Template, header row 3 and data start 5. Map item_sku to sku and item_name to title; mark both required. Leave marketplace_note unmapped. Export and check text IDs in rows 5/6, both notes and Instructions. Row 2 deliberately has duplicate readable labels. occupied-template.xlsx has OLD-RECORD in A5 and must block without replacement authorization; practice with the clean template. processing-report.csv is a fictional review record, not an Amazon response.
