TradeGecko Migration

Does anyone have experience migrating from TradeGecko to Zoey? We have all of our products, variants, and price lists in that system. The spreadsheet export of 1400 products with multiple variants, is formatted differently than Zoey. The product name is in every row of a variant whereas in Zoey it's onl on one line with the variant data in other columns. 

Ideally we'd be able to migrate with CSV vs having to manually re-enter our entire product catalog and price list array.
