This is a helpful solution to add related products. But my question is there a way you can download/export the product id in excel so it's easier to build the related products in an excel file. When I try exporting the products in excel using the admin tool, it doesn't give me the product id. Thanks.
You can try to export it to XML and then import that to Excel andyou will get a combination of all product table and its related tables in Excel, which will include ProductId
