I need a variation product uploading to linnworks

Description of excel work: We require a CSV file creating and imported to our linnworks software of a variation product which will have 4 options and 23 possible variations. All SKUs must be linked accordingly with the correct prices, extended properties. It should be ready for upload to eBay, Amazon (EAN Provided) and our website on bigcommerce. We only need main images, not images of each variant so should be straight forward on that front.

Ideally the csv will be reusable for other products also.
Extra notes: Would prefer someone with good knowledge of linnworks software.
