Hi,

It is probably quicker to write a Python script that iterates through the product list and adds all the product information to the product if you already have the products in some sort of structured, machine-readable format. models for the product.product template. You would not have to spend time manually entering each item into the CSV file.

Please refer to the following link for example:-

OR

create a single product on your own and export it with all fields, which are important to your company. After that, you can populate this csv/xls file with real data and you are set to import it.
but it takes about 0.43 seconds to import a single record.

Regards
