Migration from eShop

Does anyone know of a plugin that will migrate categories and products from the joomdonation eShop (EShop version 1.3.8, Copyright (C) 2012-2013 Ossolution Team) to woocommerce.

I have searched extensively, but cannot find a plugin that supports this particular version.

As we have over 3000 products and 300 categories, I am anxious to migrate programmatically rather than manually!
