System.FormatException when reading xlsx file

When we try to open the attached file using Aspose.Cells, a System.FormatException is thrown with the following message: “Input string was not in a correct format.” The stack trace is attached in a text file, so as to save the Unicode obfuscated method names.





In my testing, simply opening the file in Excel and saving it seems to fix the problem, but is there a way to open it successfully with Aspose without having to do that?





Thanks,
