Arithmetic operation resulted in an overflow. Arithmetic operation resulted in an overflow. Arithmetic operation resulted in an overflow

Conversion of one of the file failed while converting excel file to PDF. We are using Aspose.Cells(Ver. 7.1.1.0). Following is the exception we got. This issue happened on production due to security reasons I cannot share that file but will try to provide you scrubbed files. If possible try to fix without file. Please provide fix asap.

Code snippet:
Workbook workbook=null;
workbook = new Workbook(sourceFilePath);
Aspose.Cells.SaveOptions saveOptions = null;
saveOptions = new Aspose.Cells.XlsSaveOptions();
saveOptions.CachedFileFolder = Path.GetTempPath();
saveOptions.SaveFormat = Aspose.Cells.SaveFormat.Pdf;
if (workbook != null)
workbook.Save(destinationFilePath, saveOptions);
