Release Version 2.6.1

News: The Office2016 branch on this repo contains a preview of the Open-Xml-Sdk v3.0, which
supports the Office 2016 extensions in the file format.  The biggest change to the markup was
the introduction of the ExtendedChartPart, which support the new chart types, such as Waterfall,
Box and Whisker, and Sunburst.  You can specify FileFormatVersions.Office2016 to validate this
markup.  This version of the SDK also supports using the strongly-typed OM to access the markup
in the new parts.

We will merge the Office2016 branch into vNext at some point in the future, after receiving
feedback.

The Open XML SDK provides open-source libraries for working with Open XML Documents (DOCX, XLSX, and PPTX). It supports scenarios such as:

• High-performance generation of word-processing documents, spreadsheets, and presentations.
• Populating content in DOCX files from an XML data source.
• Splitting up (shredding) a DOCX or PPTX file into multiple files, and combining multiple DOCX / PPTX files into a single file.
• High fidelity conversion of DOCX => HTML/CSS and HTML/CSS => DOCX.
• Extraction of data from XLSX.
• Searching and replacing content in DOCX / PPTX using regular expressions.
• Updating cached data and embedded spreadsheets for charts in DOCX / PPTX.
• Document modification, such as removing tracked revisions or removing unacceptable content from documents.

Open-Xml-PowerTools provides example code and guidance for implementing many of the above important Open XML scenarios. Be sure to check it out before re-inventing your own solutions.

The Open-Xml-Sdk relies on the System.IO.Packaging namespace. There is an implementation of System.IO.Packaging in the WindowsBase assembly, and there is a new, open source implementation of System.IO.Packaging that is included with version 2.6 of the Open-Xml-Sdk. Because of this, there are six projects in the Visual Studio solution. This screen-cast describes the six projects, and explains the purpose behind each.

The most recent release of the Open XML SDK is Version 2.6.1, which includes a total of 1333 XUnit tests.

We are also happy to announce the release of Open-Xml-PowerTools on GitHub. Open-Xml-PowerTools provides example code and guidance for implementing a wide range of Open XML scenarios. You can find PowerTools for Open XML, which previously lived at PowerTools.CodePlex.com at github.com/OfficeDev/Open-Xml-PowerTools.

Version 2.6.1 : January 15, 2016

• Added hundreds of XUnit tests. There are now a total of 1333 tests. They take about 20 minutes to run, so be patient.

Version 2.6.0 : June 29, 2015

• The big feature in 2.6 is the inclusion of a replacement for System.IO.Packaging, which has a serious bug that causes it (albeit rarely and in specific circumstances) to throw exceptions (ObjectDisposedException and NullReferenceException). You can find out more about this bug and whether it affects you in the blog post that announces the release of the new System.IO.Packaging.

Going forward, the Open XML SDK will be based on this new implementation of System.IO.Packaging.

The functionality of the specific classes in Open XML SDK Version 2.6.0 is the same as for version 2.5, therefore the documentation available on MSDN is still accurate.

Open XML SDK 2.5 for Office

In addition to open sourcing of the SDK, Microsoft has opened up the conceptual documentation for public review / contributions. A copy of the documentation is now in GitHub for you to edit and review.

Note: for this first release, you must have some version of Visual Studio installed. Visual Studio 2015 Community Edition will work just fine: https://www.visualstudio.com/en-us/downloads/download-visual-studio-vs

To build the Open XML SDK:

• Clone the repo at https://github.com/OfficeDev/Open-XML-SDK
• Open the solution using Visual Studio 2013 or 2015. Community Edition of VS2015 works just fine.
• Build the solution (using either Debug or Release configuration)
• Run the Xunit tests to verify the installation

If you want to use a command line approach:

• Start a Visual Studio command prompt, and change into the directory that contains the repo
• Use MSBUILD to build the SDK (C:> MSBUILD Open-Xml-Sdk.sln)
• You can also use MSBUILD to build the individual projects.

To use the SDK:

• In your program that uses the Open XML SDK, add references to the newly built libraries in DocumentFormat.OpenXml/bin/Debug (or in DocumentFormat.OpenXml/bin/Release)

Previously, we were using PowerShell to generate a new version number for each build. This is no longer required, and it is more convenient to build the SDK using MSBUILD, therefore I have removed the instructions for building using the PowerShell script.

• First, ensure you have mono installed in a manner appropriate to your linux/unix distribution.
• make -f Makefile-Linux-Mono build
• Find libraries in the folder: ./build/OpenXmlSdkLib
