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 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.

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

Advanced Examples

  1. Step by step guide to create an invoice for a company.
  2. Replace text across many documents in Parallel.
  3. Programmatically manipulate an Image imbedded inside a document.
  4. Converting DocX into (.doc, .pdf, .html)
