Export a small sample first. Check unique product IDs, correct prices and currency, working image URLs and the relationship between variants and parent products. Validate the target channel’s required fields.
Compare a few feed entries with the live product pages. Availability, shipping and price must agree with the destination. Do not invent identifiers or descriptions to fill a validation gap.
Schedule generation only after the sample passes. Keep the last successful file and a report of rejected rows so a bad import does not silently empty the catalogue.
