Raise exception for the spread sheet file

ts1.zip (6.6 KB)
belowe is the code to reproduce :
Console.WriteLine(“Hello World!”);
string file = @“D:\tmpdel\ts1.xlsx”;
string imgpath = @“c:\tmpimg”;
//Workbook wb = new Workbook();
//wb.Worksheets[0].Cells[0, 0].PutValue(“hello”);
int pageCount = 0;
using (Viewer viewer = new Viewer(file))
//Get document info
ViewInfo info = viewer.GetViewInfo(ViewInfoOptions.ForPngView(false));
pageCount = info.Pages.Count;
//Set options and render document
PngViewOptions options = new PngViewOptions(imgpath);
catch (Exception ex)
throw ex;

actually this file is generated by cells api:
Workbook wb = new Workbook();
wb.Worksheets[0].Cells[0, 0].PutValue(“hello”);
I use the v22.9.0 version of groupdoc.viewer

after you import the aspose.cell.dll ,I use the latest v22.11.0
the exception will raise

per my check ,when I use cell.dll of v22.9.0 ,the exception will not raise.
so when will you publish the version of v22.11.0 .
as now ,we already update the version to v22.11.0


Can you please share your sample application so we could reproduce this issue on our side?

Thank you for attaching the sample application. I could reproduce this issue at my side. As workaround try using Aspose.Cells 22.7 instead of Aspose.Cells 22.11.

I need to use the latest version of Aspose.Cells 22.11 ,
when will groupdocs update the version to the latest?


In the upcoming version 22.11. It is planned to publish this version by the end of the month.
