Spreadsheet import application

Hi all

I created and populated an Action Tracker app using a site I set up to temporarily help our office whilst head office set up a global agreement with MS. I wanted to take the app and set it up in global site with all our information that we had input. I exported the file to excel and saved it then went to global site and used the import spreadsheet application and it has replicated the list perfect, however all the list settings have been saved as 'single line of text' and I can't change to add in names of people or choice menus?

Any ideas how I can do this without building the app in global site and having someone input all the data?

thanks

Darren
