How to filter and export WooCommerce products using custom taxonomy?

There may be instances where you may want to add some additional categories, tags, and brands, known as taxonomies in your WordPress site. By default, WordPress does not support custom taxonomies, and to make them work, we need third party plugins.  

When using the Product import export plugin for WooCommerce, to filter the export product data on the basis of these custom taxonomies, we can use this code snippet.

To deal with different custom taxonomies, you just have to change the existing taxonomy name: product_brand at line 3 to the required taxonomy name.
