Bad status error opening excel file

Hi all,
I have an error when trying to open an excel file that is opened correctly by Office Excel.

The error is:
Bad state ( oversubscribed dynamic bit lengths tree)

Eclosed the file.

Could you please help me to understand the error?

Thanks in advance. (341.4 KB)


Thanks for the template file.

After an initial test, I am able to reproduce the issue as you mentioned by opening the file via Aspose.Cells APIs. I got an exception “Bad state (invalid block type)” when opening the XLSX file format:
Sample code:

Workbook workbook = new Workbook("e:\\test2\\ErrorOpeningFile.xlsx");
