I have done an excel file import / export. I don't think you should use the excel importer because it is quite difficult to use for the users. Instead I think you should use a module like this:
In order to use this module you must delete the Excel Importer module , MxObject module and the deployment folder in your app (at this time the app is not running). Otherwise there will be an error.
Sorry my English is not good and I am using google translate to communicate.
