Import the listings you already have: pick a connected Amazon or eBay account and pull its live catalog into the AI workspace — no files, no mapping.
If you already sell on Amazon or eBay, you don't need a file at all — MarketplaceHub can pull your live listings straight into the AI workspace and translate them for the marketplace you're setting up. Each listing keeps its native id (ASIN / eBay item id) and its source category, which the AI uses as a head start.
The pull runs in the background — Amazon exports your listings as a report, and eBay listings are paged through eBay's API — so your products appear in the AI workspace shortly after. Amazon rows are enriched from the Amazon catalog on the way in (title, images, category and attributes).
Marketplace pulls skip the file steps entirely — no feed description, mapping or junk filters. When the pull is started, continue with Start AI Import. A bonus on the AI side: products pulled from the same marketplace you're publishing to can skip AI entirely and cost no credits — the Launchpad shows exactly how many (see AI credits).
