Reconfigure csv file for product import into WooCommerce

I need to import some sample products from a CSV file that is created by an EPOS system. I've added WooCommerce CSV suite, but struggling to map the fields correctly to import the variable products. The products are clothing items and have variations including colour and size for example I have added an example of the data to GDrive as the files can't be added here. When I import the different sizes remain as individual items. I need them to be merged so that the variations are options on a single product. To do this I need someone to reconfigure the csv file to allow it to import correctly so that the information can be replicated by the EPOS system.

I have posted this previously and the person I selected failed to complete what should be less than hours work in a week. Please only apply if you have checked the data and are 100% sure you can complete the task.
