Getting Unpresentable date time after opening XLSB document

Hi Aspose Support Team,

We are getting an “Unpresentable data time” error while opening the XLSB document. Please review this as provide us with the necessary fix.

Un-representable DateTime.zip (54.8 KB)


I am able to reproduce the issue as you mentioned by opening the file via Aspose.Cells APIs. I found an exception “Year, Month, and Day parameters describe an un-representable DateTime” on reading the XSLB file via Aspose.Cells.
Sample code:

Workbook workbook = new Workbook("e:\\test2\\CP Sample 3.xlsb");
