YITH WooCommerce Bulk Product Editing (Premium Plugin):

Have you ever had to make bulk changes to your products in WooCommerce? Yes! It is the usual answer and we all know we can not make changes to the product in bulk even if changes are similar for all products.

It also comes with the capability of creating and duplicating new products as well as exporting products in CSV format for backup. Are you planning to edit product custom fields? Yes, this extension can handle that very nicely as well.

So keep this plugin activated in your backend just in case you may need it at any time in the future. There are very few plugins that come with similar functionality.
