Bulk edit and upload of 175 k skus to shopify

I need help editing and uploading skus to Shopify. There are 175k skus. So we need to edit the lists so we can bulk upload them. When uploaded it should look like https://lightingdesign.com/ skus. Also make it shippable on the website. There are a lot of skus, But I have scraped all info and just need it edited and bulk uploaded.
