What is DocX?

DocX is a .NET library that allows developers to manipulate Word 2007/2010/2013 files, in an easy and intuitive manner. DocX is fast, lightweight and best of all it does not require Microsoft Word or Office to be installed.

NOTE: There is a new Master branch as of Oct. 3, 2017. Please read about the [Classic branch](../../wiki/Classic-Branch) if you were using this project before the change.

DocX is the free, open source version of Xceed Words for .NET. Originally written by Cathal Coffey, and maintained by Przemyslaw Klys, it is now maintained by Xceed. Starting at v1.5.0, this free and open source product is provided under the Xceed Community License agreement(for non-commercial use).

Currently, the differences between DocX and Xceed Words for .NET, is that Xceed Words for .NET :

  • can convert a Word document to PDF
  • adds properties to wrap text around Pictures/Tables/Shapes
  • adds Picture cropping
  • adds Shapes (rectangles for now)
  • adds TextBoxes or Shapes containing Text
  • gets Shapes from Paragraphs
  • gets Charts from Paragraphs and can modify their categories/values
  • More properties in Charts configuration like axis Label position and series width
  • is at least two versions ahead of the DocX version
  • has professional technical support included in the subscription
  • is available on .NET Standard 2.0 for .NET Core 2.0 Applications
  • can automatically update fields from a document
  • Insert html/rtf text (with tags), or html/rtf document, to a Word document
  • Clone lists or tables
  • Add or modify checkboxes
  • Set transparency in pictures
  • Create formatted hyperlinks based on a referenced hyperlinks
  • Joining 2 documents gives the opportunity to choose the headers/footers of doc1, doc2 or both of them in the resulting document.
  • Automatic hyphenations and configurable hyphenations

What else do I need?

All that you need to install in order to use DocX is the .NET framework 4.0 and Visual Studio 2010 or later, both of which are free.

Why would I use DocX?

DocX makes creating and manipulating documents a simple task. It does not use COM libraries nor does it require Microsoft Office to be installed.

The following blog post from Cathal Coffey compares the code used to create a HelloWorld document using:

  1. Office Interop libraries,
  3. DocX
