It looks (by your exception) like your file is not native/valid Excel file, to confirm this, you may try to open the file into notepad, if it is a web page or else. Also for your kind information, we only support BIFF8 and greater formats (Excel 97 - 2010), the earlier formats or other formats are not supported.

If you still could not evaluate or find the issue, attach your source file here, we will check it soon.


Thank you.
