Trouble figuring out attribute import to shopify

I have both variable and simple products on woocommerce.

Issue 1 : For simple products the attributes are getting imported to the meta fields but when it comes to the attributes with global values, only the id’s are getting imported.

Q 1. How to get the global attribute values imported?

Issue 2 : If I’m not wrong, for the variable products there is no bulk import. Find the attached screenshot. For importing Style Info, I tried both ‘_product_attributes.style-info’ and ‘_product_attributes.style-info.value’. Both didn’t work.

Q 2. What is the correct way to pick the attribute key?

From shopify I’m using the correct namespace and key
