Copy Address infromation to external shipping/delivery website

Hello,

We will be using Salesforce to deal with our orders and information from Shopify. 

We then have to create a shipping/delivery label using the delivery companies website.

Is there a way to easily copy the shipping address and customer name data from the salesforce opportunity and paste it into the delivery company website? 

We are in the UK and use a few different couriers depening on what we are sending (from small prcels to pallets).

If not, do you have any suggestions on how we could enter the delivery details easily, other than copying and pasting each line?

Thanks
