For your convenience, CloudCart's technical team has added new functionality for CSV files - Handle ID.
Here you can read in detail how to add a CSV file to your store: Import products through a CSV file
Adding variants via Handle ID
In our sample CSV File, the option to import variants has already been added - the Handle ID column.
* Each product has an ID number, which is usually in the first column, and each row of information in that column is a new product.
* When you import products with multiple variants, each variant has a Handle ID, into it you would indicate which product is the specific row (variant) assigned to.
* When you have added a row-variant, the ID column remains blank in the specific row, and in the Handle ID column you indicate which product (ID) refers to that particular variant.
