I'm keen to see a CSV import module happening (or write one myself). I was thnking that perhaps going from

Excel -> CSV -> XML -> Ubercart

would be the way forward since the XML importer already exists. Is there a spec for the XML that Ubcercart likes?

Now that I'm thinking about it perhaps Excel could export to XML and then a general XSLT template could be developed to et this in the UC preferred format?
