BigCommerce Variant CSV Format

Place the Product row before its Variant and Image rows. Keep all rows for one product together so option and image data cannot drift to another group.

This synthetic subset demonstrates the Options format observed in the linked public sample and supported by the current checker. Each option has Type, Name and Value fields separated by vertical bars; join options directly, with the next Type= starting a new option. Other dialects are not inferred from the baseline. Copy the complete header set from a fresh destination-store export.

Duplicate option combinations, inconsistent option names, orphan variants, and repeated SKUs require manual correction. Do not generate or overwrite variant identity values automatically.
