To solve this problem, I decided to use report a shopify store https://apps.shopify.com/exportier-advanced-data-export . This is an email marketing app specially designed for Shopify and helps you export data in CSV (.csv) and Excel (.xlsx) formats. It has convenient filters and sorting, which allows me to reduce the volume of uploading and increase the speed of preparing data for export.

I suggest you explore the site https://www.shopping-cart-migration.com/shopping-cart-migration-options/28509-squarespace-to-shopify-migration. Here you will find a lot of useful information on this topic. I guarantee!
