Brand

No, it will import the brands into brands, not into attributes.

To import the brands, you need both:

• FG OpenCart to WooCommerce Premium https://www.fredericgilles.net/fg-opencart-to-woocommerce/
• and the Brands add-on https://www.fredericgilles.net/fg-opencart-to-woocommerce/brands/

It also requires a WordPress plugin that manages the brands:

• either WooCommerce Brands
• or Perfect WooCommerce Brands
• or Ultimate WooCommerce Brands
• or YITH WooCommerce Brands Add-on free or Premium
• or a theme that can manage brands using the «brand» taxonomy
