" It is because when you import existing employees information, it will either duplicate or unable to import since the file already exists in your Quickbooks Desktop account."
I'm surprised you're an employee, because this statement is incorrect. I've performed this procedure in QuickBooks desktop several times now without duplicates / failures.
What REALLY needs to happen is that Intuit developers need to write code to handle data that is formatted outside what is expect for that field and/or correct the field to limit data entry of certain characters or text. This is a QuickBooks issue that needs to be corrected, instead of Intuit relying on it's users to export and edit data that QuickBooks doesn't "like".
