html to openxml

How to start ?

Create a new console application. Add a reference to DocumentFormat.OpenXml.dll (shipped with the OpenXml SDK 2.0).
Add an html file and fill it with:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
     <head>
          <title></title>
     </head>
     <body>
          Looks how cool is <font size="x-large"><b>Open Xml</b></font>.
          Now with <font color="red"><u>HtmlToOpenXml</u></font>, it nevers been so easy to convert html.

     </body>
</html>

Add a Resources.resx component and add your html file inside it.

In Program.cs, add these lines of code:

using System.IO;
using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;
using NotesFor.HtmlToOpenXml;
...

static void Main(string[] args)
{
     const string filename = "test.docx";
     string html = Properties.Resources.DemoHtml;

     if (File.Exists(filename)) File.Delete(filename);

     using (MemoryStream generatedDocument = new MemoryStream())
     {
          using (WordprocessingDocument package = WordprocessingDocument.Create(generatedDocument, WordprocessingDocumentType.Document))
          {
               MainDocumentPart mainPart = package.MainDocumentPart;
               if (mainPart == null)
               {
                    mainPart = package.AddMainDocumentPart();
                    new Document(new Body()).Save(mainPart);
               }

               HtmlConverter converter = new HtmlConverter(mainPart);
               Body body = mainPart.Document.Body;

               var paragraphs = converter.Parse(html);
               for (int i = 0; i < paragraphs.Count; i++)
               {
                    body.Append(paragraphs[i]);
               }

               mainPart.Document.Save();
          }

          File.WriteAllBytes(filename, generatedDocument.ToArray());
     }

     System.Diagnostics.Process.Start(filename);
}
