Viewer cannot convert XLS files to html

GroupDocs.Viewer Product Family
1

Hi, We have an evaluation license for the Viewer for .Net.(version 18.4.0.0) We have been testing different types of files but we found that when we try to convert to html any .xls files we get an error saying the file is corrupted or damaged. I can open those files without problems from the file system though. (Notice that .xlsx files are converted without any issues).

Is this a bug or is just that xls files are not supported?

Thanks.

Hi Usman, thank you for the prompt response.

Please, find attached one of the files that is failing to be converted and the code we are using, below.

 public static List<PageHtml> RenderWithGridLinesInExcel(String DocumentName)
        {
            // Setup GroupDocs.Viewer config
            ViewerConfig config = Utilities.GetConfigurations();

            ViewerHtmlHandler htmlHandler = new ViewerHtmlHandler(config);

            // File guid
            string guid = DocumentName;

            // Set html options to show grid lines
            HtmlOptions options = new HtmlOptions();
            //do same while using ImageOptions
            options.CellsOptions.ShowGridLines = true;

            List<PageHtml> pages = htmlHandler.GetPages(guid, options);
            return pages;
        }
