[MarketPress] MarketPress Import

I have a potential new client and need to advice. They are using an old DotNetNuke site with a Catalook cart. The Catalook cart stopped working for them because Authorize.net no longer supports the version they are using. I suggested migrating to WP and using MarketPress. They don’t have a lot of content to migrate but they have hundreds of products. Do you know of any export/import functions that I could use to migrate their current cart to MarketPress?

Additional Note:

I found a function in their current cart that allows exporting all product details into a variety of formats: xml, Excel, html, csv or text. Is there an equivalent import feature for MarketPress?
