OverflowException exception on opening workbook


An exception when opening the excel file attached:

System.OverflowException: Value was either too large or too small for an

NumberFormatInfo info)
at ”…‚(XmlElement , , Boolean )

            var fileName = @“Portfolio Investments Collection Tempate_7.xlsx”;
var workbook = new AC.Workbook(fileName);
Removing formulas (or unhiding the column) from column A on ‘GAP VI Investments’ sheet helps.

Hi Leo,

Thanks for your posting and using Aspose.Cells.

Please download and use the latest version: Aspose.Cells
for .NET v8.2.0.2
it does not throw any exception while loading this file.

We tested it with the following code and the Excel file was loaded fine.


string filePath = @“F:\Portfolio+Investments+Collection+Tempate_7.xlsx”;

var workbook = new Workbook(filePath);

Thanks Shakeel! Yes, it works in
