System throw issue on ‘memStr’ and getting Object reference is not set to instance of an object.

@vagarwal,

Thanks for the template file and sample code segment.

Your attached MS Excel file is corrupt which cannot be opened into MS Excel as I tested (after changing the extension to .xlsx). Please attach a valid file which can be opened fine into Ms Excel manually. Also, please use Aspose.Cells APIs instead of Aspose.Words as Aspose.Cells is a spreadsheet component used to create, manipulate or render MS Excel files.
