Hello, You can use the woo-commerce import and export feature for updating the product price in bulk using the CSV file
1.Generate the woo-commerce export with all meta keys.
2.You can search for the meta key for which you are looking for making the changes like you want to update the role-based price for admin and customer –
Meta: product_role_based_price_administrator
Meta: product_role_based_price_customer
3.In the same way you can search for different meta keys which will represent the options on the product page.
4.After making the desired changes save the CSV file.
5.Upload the CSV file on your site using the woo-commerce import function and update the existing values in the products.
Hope this helps. Let us know if you face any trouble.
Thanks
