Opening an XLS file via Aspose.Cells APIs

Hi,

I get a NullReferenceException when opening a workbook like:
var theWorkbook = new Workbook(filename);

Stacktrace:
at . . ( )
at . .Read( )
at Aspose.Cells.Workbook. (String , LoadOptions )
at Aspose.Cells.Workbook…ctor(String file)

Tested with Aspose Cells .NET 2.0:
- v7.4.0
- v7.7.2
- v8.1.2

See the attached sheet.

Hi Ronald,

Thanks for your posting and using Aspose.Cells.

Actually, your source xls file is corrupt. It does not open fine in MS-Excel 2010. It shows the warning as shown in this screenshot. Therefore Aspose.Cells also throws exception on opening it.

However, we have logged this issue in our database for further investigation. We will look into it and fix this issue if possible. Once, there is some fix or other update for you, we will let you know asap.

This issue has been logged as CELLSNET-42863.

C#


string filePath = @“F:\Shak-Data-RW\Downloads\Sheet+Deelnemers+Online+24-07-2014.xls”;


Workbook workbook = new Workbook(filePath);

Exception:
A first chance exception of type 'System.NullReferenceException' occurred in Aspose.Cells.dll

Thanks for your quick reply. I have Office 2013 here, and have no problem opening the sheet.

Hello Shakeel,

Our customer told me he created this sheet with Excel 2007. So it appears to be a valid sheet for Excel 2007 and 2013, but not for Excel 2010.
