How to import products with variants and attribute prices

I don't have enough Karma to post a comment, so I have to put this as an answer.

For those who are finding this post, the accepted answer worked great but I didn't know how to create this menu item in step 6:

6. To import variant prices for more than one product template at one time, you will need to create a new menu item for product.template.attribute.value.

I was able to figure it out by doing the following (using Odoo Studio, Odoo Enterprise 16):

1. Open the Inventory module.2. Open Odoo Studio using the icon in the top right bar.3. Click on Edit Menu4. Click New Menu5. Give the menu a name, I chose "Product Template Attribute Value"6. Select Existing Model7. For the model, select "Product Template Attribute Value"8. Hit Confirm.9. You can drag and drop the new Menu Item wherever makes sense to you...I put it under Inventory -> Products.  This new link will show up in the top menu area when you are on the Inventory module.10. Visit the new menu item page.  You won't be able to import from this page, yet!11. Make sure you have debug mode enabled.12. Click on the debug button, and go to Edit View: List13. Change create="0" to create="1" and then click save.14. Refresh the page.  You'll now be able to Import Records from the Favorites menu on the page.
