@kumar.penigalapati,

Please notice, we were able to reproduce the issue using your template file and following sample code. We found some HTML contents are missing the output Excel file.
e.g.
Sample code:

HtmlLoadOptions opts = new HtmlLoadOptions(LoadFormat.Html);
            opts.AutoFitColsAndRows = true;
            Workbook workbook = new Workbook("e:\\test2\\HtmlPage8.html", opts);
            string output = "e:\\test2\\out1.xlsx";
            workbook.Save(output);

We have logged a separate ticket with an id “CELLSNET-47920” for your issue. We will look into it soon.

Once we have an update on it, we will let you know.

Hi Ahsan Iqbal,
we are not able to download the drop box file because if some firewall ristrictions.
the code which i am using is like this

string bgresult = System.IO.File.ReadAllText(path1 + “\HtmlFiles\HtmlPage10.html”);
using (MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(bgresult)))
{
HtmlLoadOptions options = new HtmlLoadOptions(LoadFormat.Html);
options.AutoFitColsAndRows = true;
options.StreamProvider = new StreamProvider47584(proxyurl);

            Workbook wb = new Workbook(stream, options);

            Worksheet ws = wb.Worksheets[0];
            ws.Name = "Test";
            ws.AutoFitRows();
            ws.AutoFitColumns();

            PageSetup pageSetup = ws.PageSetup;
            pageSetup.SetHeader(1, string.Format("&\"Times New Roman,Bold\"Title: {0} {1} {2}", "Test BillingGuide Name", "Enabled", DateTime.Now.ToString("yyyy-mm-dd")));

            wb.Save(path1 + "\\Page_out.xlsx", SaveFormat.Xlsx);
        }

can you send me like zip file ?

35

@kumar.penigalapati,
Thank you for sharing sample code. It is observed that this issue is caused by using the following line of code:

options.AutoFitColsAndRows = true;

You may please remove this line of code and try the scenario again. As you have already used AutoFitRows and AutoFitColumns for the output Excel file therefore the output seems fine.

36

Thanks Ahsan Iqbal,
after removing that line its working fine.
but will this have any other implications of other scenarios ?

37

@kumar.penigalapati,

There would be no consequences. For certain scenarios, you may skip this option when loading the HTML.

38

Thanks Amjad Sahi ,
I am seeing the spaces in Excel now.
Thank you!!
