Render large excel files is taking too long

i would like to ask you, what is the best way to render large excel files, for example with 8000 records? I downloaded sample ASP.NET WebForms project and tried to render large excel files but it takes too long time ( about 30s or even more). Is there any solution to rener files partially? Is worth to mention that i’m working with GroupdDocs Viewer 3.7. In attachment you will find sample document. This problem occurs when i try to switch from first to second tab of excel file.


Hi Witold,

Thanks for using GroupDocs.Viewer for .NET.

Currently, GroupDocs.Viewer for .NET API does not support partial rendering of large Excel sheets. However, I have logged your request as a new feature in our issue tracking system for further analysis and investigations.

Furthermore, as we can see that you are using an older version of the API therefore, for a better experience, we strongly recommend you to upgrade to the latest version which is GroupDocs.Viewer for .NET 16.12.0.

Have a nice weekend ahead.
Warm Regards
