    Is there a programmatic way, other than looking at the file extension, to know whether a user opened a xls or xlsx file in Spread.Net 6?

    There is not a way to determine the type of Excel file opened in Spread, you would need to check the extension of the file to determine whether a user has opened a .xls or a .xlsx file in Spread. Hope it will help you. Please let me know if you have any queries further.
