date field issue
Excel handles dates differently to Power BI, so you may need to format the Excel file separately. Only way around this would be to format the date in Power BI as a text column, so that the exact formatting is preserved on export to Excel, but this won't be able to be used in any calculations or sorting.

Dates are actually just serial numbers counting number of days since Jan 1, 1900

There is actually a date data type.
Formatting (MM/DD/YYYY vs DD/MM/YYYY) is a different thing again to data type, so this does not get preserved on export.
