How does WooCommerce store products / product variations? / Free Script to import product variations? [closed]

So I’m just working for a client right now importing CSVs of products to WooCommerce. I’ve imported a lot of products so far using an existing plugin, but don’t want to buy the CSV Product Import Suite for $99 to import product variations.

So… Can anyone help me to answer one of the following two questions:

1. Does anyone know a free WooCommerce plugin / script that will let me import product variations?

2. If not, can anyone explain to me HOW WooCommerce stores product variations in the MySQL database, so that I can write a script to import product variations?

Cheers!!

This one is not as extensive as the woo product but works very well and you can easily
modify it. Good luck.
By the way, today, and I don’t know for how long, woo is having a 50% discount on their plugins. Just go to their site.

Here’s your plugin link
