Sort Inventory "All Products" by Sku

Hello, is there a way to sort inventory on "All Products" by Sku, as opposed to stock or price? I want to update my inventory quantity. I'm aware you can update stock amount via the CSV template, but that includes a ton of other information I don't need to update, only stock. If I do it via the CSV template, can I delete all other headers except SKU & Stock, and will it accept the upload that way? I also do not need to update all products, so the export contains a ton of unnecessary information. Is there a better way?
