Open-XML-SDK

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
Document modification, such as removing tracked revisions or removing unacceptable content from documents
Data and content querying and extraction, such as transformation from DOCX to HTML, or extraction of data from spreadsheets

Documentation

This release of the SDK is the exact source code 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.

Build Instructions

For a video that shows how to get and build the SDK, see this blog post at OpenXmlDeveloper.org.

Note: for this first release, you must have some version of Visual Studio installed. Visual Studio 2012 Express Edition will work just fine: http://www.microsoft.com/en-us/download/details.aspx?id=34673

Set Execution Policy for PowerShell

In order to run the script that builds the Open XML SDK, you need to set the execution policy. To set the execution policy, you must run PowerShell as administrator.

Right click on the PowerShell shortcut, and click "Run as administrator". An easy way to find the PowerShell shortcut is to click the Start button, then type PowerShell. The PowerShell shortcut will be in the search results above the start menu.
Click the Yes button in the User Account Control dialog box.
Run the command to set the execution policy: The the PowerShell prompt, type: Set-ExecutionPolicy Unrestricted
The Set-ExecutionPolicy cmdlet asks: Do you want to change the execution policy? [Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): Press Y Enter
You can exit the PowerShell session that is running as administrator. At the PowerShell prompt, type: Exit

Build the Open XML SDK Libraries

Start a Visual Studio command prompt. It does not need to run as administrator.
Change directories into the directory that contains this README.md, and the PowerShell script BldSdk.ps1 For instance, type: CD C:\users\username\Documents\Open-Xml-Sdk
Start PowerShell. At the DOS command prompt, type: PowerShell Enter
Run the PowerShell script to build the libraries: Type: ./BldSdk.ps1 Enter
The build will commence - it can take a few seconds, up to a minute, depending on the speed of your computer.
Find the debug libraries in the folder: ./build/OpenXmlSdkLib/Debug. Find the release libraries in the folder: ./build/OpenXmlSdkLib/Release

Building with Mono

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

Building with Visual Studio

The Visual Studio project contains a pre-build command line that launches a PowerShell script which sets the version string of the AssemblyInfo.cs (in roughly the same way as the normal command line build script). To be able to execute that pre-build command line, you must also set the execution policy as described above. Should you have multiple PowerShell shortcuts, you must use the right one for your Visual Studio installation.

If you get the error "The command "cd C:\Users\Eric\Documents\Open-Xml-Sdk
powershell ./SetAssemblyVersionString.ps1" exited with code 1, then you need to set your execution policy. There is a different execution policy for PowerShell scripts that are run from Visual Studio. To set this execution policy:

Start a COMMAND prompt (not PowerShell console) as Administrator
Enter the following command:

C:\windows\system32>c:\windows\syswow64\WindowsPowerShell\v1.0\powershell.exe -command set-executionpolicy unrestricted
