Splitting variants
If a product has more than one variant, then you can split each variant into an individual product. For example, if a product has three color variants, then you can convert each color variant into an individual product that you can sell in your store.
Steps:
Add the product that you want to split to your import list.
From your import list, find the product that you want to split, and click More Actions > Split Product.
Select how you want to split your products. For example, if a product has both color and size variants, then select Color to split it into individual products based on color.
Click Split to Products.
When you create a new product, unused variants are disabled instead of deleted. You can enable a specific variant any time after you have split the product.
