java.lang.NumberFormatException while processing excel file


When we try to process excel file , we get exception. We are using cells latest version
java.lang.NumberFormatException: For input string: "au" (1.8 KB)


I have opened this file in Excel 365 where it raises exception. This file seems to be corrupted, therefore you may please provide us a sample file which opens fine in Excel but raises exception with Aspose.Cells. We will test it here and provide assistance accordingly.
