Actinic to OSCommerce easypopulate CSV conversion

I have an export of an Actinic ecommerce website in CSV format. My customer would like to move to an oscommerce site. To do this the CSV needs to be converted to a format (CSV) that is compatible with the "easypopulate" module for oscommerce (EP_v2_76i_MS2). I can supply the CSV and would expect a working script, preferably in PHP, that can be used to convert the site. I can also supply a demo site for testing (to make sure the import works)
