Hi Zhifang,
Normally if Microsoft Office cannot open an Excel file, that means the format or structure of the file is incorrect.
Does this happen using only the built-in export functionality, or there is a Custom code you have that creates the Excel Document and exports it?
Can you please share the complete ASPX ASPX.CS/VB Page so we can double-check and see how the application is created.
I look forward to hearing from you.
