Invalid linechart marker or grouping string val

Hi - we’re using Aspose.Cell .NET to process Excel files we receive from a third-party partner. They recently changed their process to generate the files and now they send us Excel 2007 (.xlsx) formatted files, instead of Excel 2003 (.xls) formated files.

When we try to initialize a new Worksheet using the new file, Aspose throws an exception, Invalid linechart marker or grouping string val.

What’s interesting is, if I just open and save the file in Excel, no changes, same Excel 2007 format, Aspose loads the file successfully.

I can’t find any references to that error message. Do you have some more information on it and why it might be resolved by re-saving the file?

Thanks! (424.5 KB)

Hi - I tried that, but I get an error that I can only upload image files.

Sorry - just uploaded a zip file.

Thanks - if you know what the issue in the Excel file is, I can reach out to our partner to see if they can correct the issue, too.
