// STEPS
01
Required columns are name, category, and image_url.
02
Optional columns are sku, features, brand_notes, and marketplace.
03
Use one row per SKU.
04
Use a publicly reachable image URL in image_url.
05
Put feature claims in the features column, separated by | or ; when using one cell.
// SELLER TIPS
Do not paste local file paths into image_url.
Short, factual feature claims produce cleaner listing images.
Brand notes can be reused across rows when the catalog belongs to one brand.
