Hi,
If the mass-action does not feet to your needs, you can use the export/import system in order to import the variant data and import the prices in the same time.
If you import just the variant data, it will update only these elements.
Once some products are in place, the best for you will be to copy one existing product when creating new one.
So it will duplicate a product, his variants and his prices.
