New to the forums and just wanted to raise a query - I don't have a heavy tech background so some of the intricacies of Magento go over my head from time to time! My Magento site is a retail clothing site, which requires a lot of simple products for every size and colour. It can be quite tedious to do, so I was hoping to bulk upload.

System -> Import/Export ->Export All Products -> Run Profile - Run Profile in Pop-up
