Hi!

We are getting FormatExceptions while trying to convert the xlsx files from the archive below to html, using Aspose.Cells for .Net 20.7.0 and the following code:

AsposeLicenser.LoadLicense();

var options = new HtmlSaveOptions
{
    ExportImagesAsBase64 = true,
    ExportSingleTab = true,
    ExportHiddenWorksheet = false,
    ExportGridLines = true
};

using (var wb = new Workbook(file))
    wb.Save(file + "_output.html", options);
