Can I import multiple metafield columns into product specifications?

Hi,

I want to know if it is possible to have say, 100 different metafield columns on excel that correlate to product specifications

For example: Height, Width, Dept, Weight

But also things like Gas Rating, Electrical Rating

Then import these columns into shopify that add them to a specification table (picture attached)

The catch is, for items that are gas - the electrical rating colum will be blank, so i don’t want to show this visible in the table on the product page, only columns that have been filled in.

Most products have different specification lists, so it would really streamline my process as I would not have to make an individual table for each of my products.

thanks

Jack
