Hello John,

We are sorry to hear that you have such issue. From your request we can assume that you didn’t set a path for the file to view in the Viewer widget. To resolve the issue we need additional info from you. Could you please share with us example of your code which integrates GroupDocs.Viewer into the web page so we can check it.

If you will have more questions please feel free to contact us.

I am using the document-viewer servlet provided by you all. It works with various other documents but I get that error when I try and upload the spreadsheet I attached.
