I am using magmi to import products into Magento.
I have a long list of simple products in a spreadsheet and it is a right pain going through it and adding a configurable product row for each set of products manually. It is of course also error prone.
I wonder if there is a way of processing this sheet automatically to add in the configurable product rows. It's fairly easy to see when one set of products changes to another.
I've browsed lots of forums and tried to do it through excel but can't seem to find a way of doing it. Has anyone any suggestions please?
