Render XLSX- Document to HTML exception



I get an exception invalid parameter) when I try to render a XLSX-File to html.
If I try the render the same file in doc or xls format its work fine, but this is not a solutions for us. We need to render xlsx files in html.
I guess why the rendering doesnt work, that the xlsx file contains function that not supported.

In general rendering of the xlsx file is work, but if i have a file with a lot of functions doesnt work.

Has anyone hat this problem already and how I fix this problem.
The resolve this problem is very important for me.

I have attached the file for example.

Hi there,

Thanks for your cooperation.

As per the latest updates, the charts/graphs in your provided Excel document are basically sparkline shapes which are not supported by GroupDocs.Viewer API. Even if you open that file in MS Excel and save it as Web Page, the sparkline shapes will be missing there too.

Therefore, this feature is not supported yet and there are no plans to support it in nearest future. We apologize for inconvenience.

Warm Regards
