Upload Excel CSV of product variations via Woocommerce variations plugin

General information for the website: WooCommerce based website
Kind of development: Customization of existing website
Description of requirements/features: I need someone with experience of the WooCommerce plugin: https://wordpress.org/plugins/woocommerce-csvimport/

This plugin allows for the upload of variations as I've purchased this extension: https://allaerd.org/shop/woocommerce-import-variable-products/

The products I need to upload are only two in number, but each has over 400 variations.

I WILL SUPPLY THE COMPLETE CSV FULL OF DATA, YOU WILL MERELY INSTRUCT ME ON HOW THE EXCEL SHEET SHOULD BE CONSTRUCTED (E.G. HOW THE TABLE/HEADINGS SHOULD BE LAID OUT) AND THEN UPLOAD IT.

FOR SOMEONE WITH EXPERIENCE THIS WILL BE A COUPLE OF HOURS WORK AT MOST.

Thanks!
