Aspose.Cells - Invalid BIFF8 file

Aspose.Cells Product Family

I attached the project. I understand that the file might be indeed corrupt. Just need more details on why is it considered invalid.

Error message: Invalid BIFF8 file.
StackTrace:

@brunojuliao,

Thanks for the sample project with template file.

After an initial test, I am able to observe the issue as you mentioned by loading your template file. I found an exception “Invalid BIFF8 file” when loading an XLS file:
e.g
Sample code:

var filename = "e:\\test2\\[20180620103237055][SVN_MICS-USA_IBAS][PL][USD][21324]OriginalPL.xls"; 
            var temp = new Workbook(filename, new LoadOptions() { LoadFilter = new LoadFilter(LoadDataFilterOptions.CellData), CheckExcelRestriction = false }); 
            Console.WriteLine("Done") ;

I have logged a ticket with an id “CELLSNET-46214” for your issue. We will look into it soon.

Once we have an update on it, we will let you know here.
