Export excel to html with conditional formatting white background

Hi there,

I have an excel which contains conditional formatting in its cells.
Using the following code with Aspose.Cells v23.6 I export it as html

  private static HtmlSaveOptions _htmlSaveOptions =>
            ExportImagesAsBase64 = true,
            ExportPrintAreaOnly = true,
            ExportHiddenWorksheet = false,
            ExcludeUnusedStyles = true,
            ExportActiveWorksheetOnly = true,
            Encoding = Encoding.UTF8

    public static void ExportHtml()
        Workbook wbc = null;
        using (FileStream ms = new FileStream(@"C:\demo-projects\aspose-html\input.xlsx", FileMode.Open))
            wbc = new Workbook(ms, new LoadOptions(LoadFormat.Xlsx));

        var worksheet = wbc.Worksheets[0];
        using var html = new MemoryStream();
        wbc.Save(html, _htmlSaveOptions);
        File.WriteAllBytes(@"C:\demo-projects\aspose-html\output-23.6.html", html.ToArray());
        wbc.Save(@"C:\demo-projects\aspose-html\output-23.6.xlsx", SaveFormat.Xlsx);

There’s a regression from Aspose.Cells v23.5:
In the output html, cells containing conditional formatting have a white background around them, which is not the styling in the original excel.

Attached is a zip file containing:

  1. input.xlsx - original input file.
  2. output-23.6 - html output using Aspose.Cell 23.6
  3. output-23.5 - html output using Aspose.Cell 23.5

Hi @eduardo.canal,

As this issue a regression, and we had to revert Aspose.Cells to 23.5, when is a fix expected to be deployed?
