Is your concern around your current data formats and how to map it to Shopify? The fields Shopify offers don't have the extensive range of library databases however you can merge a lot of the data into description and tags so you can still show the data you want and have it categorised correctly. There is a probably a bigger discussion in how to map the data based on templates you would define and then import it into Shopify. If it just a one off you could build your files within excel. We operate our own product data solution that is based around connecting and mapping data between platforms.
