My technical experience: Generating MS Word 2007 file from html content

Monday, June 7, 2010

Hello everyone,

My teammate was given a task to edit html markup content stored in a database and to generate a word document from the edited html content. I used "DocumentFormat.OpenXml" to generate a word document from the html content. Happy to solve my teammate's problem :).

The below code use a template word document. Using the template, a new document is generated on server. The file can be deleted from the server once client has downloaded.

Add two dlls DocumentFormat.OpenXml.dll and WindowsBase.dll in your web application/ website.

Add references "DocumentFormat.OpenXml.Packaging" and "DocumentFormat.OpenXml.Wordprocessing" in your code.

Code:


//It will generate Word 2007 document for the html content.
public static void GenerateWordDocFromHTMLContent(string templateFilePath, string documentFilePath, DataTable data, string fileName)
{
  File.Copy(templateFilePath, documentFilePath, true);

  using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(documentFilePath, true))
  {
      MainDocumentPart mainPart = wordDoc.MainDocumentPart;
      int altChunkIdCounter = 1;
      int blockLevelCounter = 1;

      //Fetch the html content from DataTable. Let us take first record.
      string htmlContent = data.Rows[0]["HTMLMarkUp"].ToString();
      string html = "<html><body>" + htmlContent + "</html></body>";
      string altChunkId = String.Format("AltChunkId{0}", altChunkIdCounter++);

      //Import data as html content using Altchunk
      AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(AlternativeFormatImportPartType.Xhtml, altChunkId);

      using (Stream chunkStream = chunk.GetStream(FileMode.Create, FileAccess.Write))
      using (StreamWriter stringStream = new StreamWriter(chunkStream, Encoding.UTF8)) //Encoding.UTF8 is important to remove special characters
          stringStream.Write(html);

      AltChunk altChunk = new AltChunk();
      altChunk.Id = altChunkId;

      mainPart.Document.Body.InsertAt(altChunk, blockLevelCounter++);
      mainPart.Document.Save();
  }
}

Note: The content type or Mime type for word 2007 file is "application/vnd.openxmlformats-officedocument.wordprocessingml.document"
