.NET API for Manipulating Word Processing Documents

Getting Started with DocX

First of all, you need to install .NET framework 4.0 and Visual Studio 2010 or later, in order to use DocX smoothly. 

The recommended way to install is using NuGet

 Install-Package DocX -Version 1.5.0

Create & Modify Word Documents via .NET APIs

The open source DocX API allows software developers to create new Word documents in DOCX file formats. The library also allows modification of the existing Word Documents according to the user’s needs. The API also supports adding a picture, inserting a table and hyperlinks, and adding paragraphs or bulleted lists and a numbered list inside word documents.

using (DocX document = DocX.Create("fileformat.docx"))
{
  // Add a new Paragraph to the document.
  Paragraph pagagraph = document.InsertParagraph();
  // Append some text.
  pagagraph.Append("File Format Developer Guide").Font("Arial Black");
  // Save the document.
  document.Save();
}

Manage Custom Headers/Footers in Word Files

The DocX API enables Software developers to add custom headers and footers inside Word DOCX Documents. The API supports adding custom headers/footers with tables and pictures, paragraphs, and charts. Once the document is created you can define the page's header's picture in a Table. Odd and even pages will have the same headers. You can also describe the page's footer's picture or text in a Table.

//Create a document
using (DocX document = DocX.Create("FileFormat.docx"))
{
  // Add Header 
  document.AddHeaders();
  Header header = document.Headers.Odd;
  // Insert Paragraph in header
  Paragraph paragraph = header.InsertParagraph();
  paragraph.Append("File Format Developer Guide");
  // Add Footer 
  document.AddFooters();
  Footer footer = document.Footers.Odd;
  // Insert Paragraph in header
  Paragraph paragraph1 = footer.InsertParagraph();
  paragraph1.Append("File Format Develoer Guide");
  // Save Document
  document.Save();
}

Manipulate Image inside a Word Document

The DocX API allows software developers to programmatically manipulate images embedded inside Word DOCX documents. First of all, you need to have an image inside a word document. To manipulate the image first you need to open the document and write a custom string or other changes you want to apply to an image and after that save the document.

using (DocX document = DocX.Load("FileFormat.docx"))
{
  //Read Image from word
  var image = document.Images[0];
  Bitmap bitmap = new Bitmap(image.GetStream(FileMode.Open, FileAccess.ReadWrite));
  Graphics graphics = Graphics.FromImage(bitmap);
  // Draw the string
  graphics.DrawString
  (
  "Manipulate Images using DocX",
  new System.Drawing.Font("Tahoma", 20),
  Brushes.Blue,
  new PointF(0, 0)
  );
  // Save document
  document.SaveAs("Output.docx");
}

Manage Hyperlinks in Word Documents

The hyperlink is a very useful part of word processing documents that allows users to access external documents or internal parts of the existing documents as well as external websites and email addresses directly from the document. The open source DocX API provides support for both two types of hyperlinks; the internal which points to a bookmark inside the document and the external which points to the external URL.

// reating a bookmark
const chapter1 = new Paragraph({
  heading: HeadingLevel.HEADING_1,
  children: [
    new Bookmark({
      id: "anchorForChapter1",
      children: [
        new TextRun("Chapter 1"),
      ],
    }),
  ],
})

//Create an hyperlink 

const link = new InternalHyperlink({
  children: [
    new TextRun({
      text: "See Chapter 1",
      style: "Hyperlink",
    }),
  ],
  anchor: "anchorForChapter1",
})
