Whoops, sorry about that! That was indeed the wrong link. Here’s the right one:

thanks. I don’t have any other option. These products are quite difficult to tag or categories.
I think you’ll find grouping that many producs together will cause other problems in terms of management.
You can set the products to be grouped using the core CSV product importer:
https://github.com/woocommerce/woocommerce/wiki/Product-CSV-Import-Schema
However, I’m not seeing an option for how to tell it which products to group together. The best thing to do would be create a grouped product on your site, link it together with the products you’d like to group, then export the products to CSV. That should tell you how to do it.
