I know there are a few modules out there that allow you to import userlists into a portal etc. heres my question

Is there any examples of importing an excell spreadsheet and then allowing the user to map columns from the spreadsheet to fields in the profile -

heres the scenario that I am looking at

We need to allow each company to keep a profile for its employees - each company may have different requirements for the profile from the others - so when a import of employees is done we want them to be able to upload a spreadsheet and then be able to say column1 is the first name and column2 is the last name and column3 is the email etc. etc.

Anybody got some cool ideas on doing this in a module? Or maybe an example (doenst have to be DNN) where they think this works real well!?!
