The Open XML SDK provides tools for working with Office Word, Excel, and PowerPoint documents. It supports scenarios such as:

- High-performance generation of word-processing documents, spreadsheets, and presentations.
- Document modification, such as adding, updating, and removing content and metadata.
- Search and replace content using regular expressions.
- Splitting up (shredding) a file into multiple files, and combining multiple files into a single file.
- Updating cached data and embedded spreadsheets for charts in Word/PowerPoint.

Releases
--------------------------------

The official release NuGet packages for Open XML SDK are [available on Nuget.org](https://www.nuget.org/packages/DocumentFormat.OpenXml).

The NuGet package for the latest builds of the Open XML SDK is available as a custom feed on MyGet. You can trust this package source, since the custom feed is locked and only this project feeds into the source. Stable releases here will be mirrored onto NuGet and will be identical.

For latests changes, please see the [changelog](CHANGELOG.md)

The package currently supports the following frameworks:

- .NET Framework 3.5+
- .NET Standard 1.3+
- .NET Core 1.0+
- .NET 5+
- Mono 4.6+
- Xamarin.iOS 10.0+
- Xamarin.Mac 3.0+
- Xamarin.Android 7.0+
- UWP 10.0+
- Unity 2018.1+

For details on platform support, please see the docs at https://docs.microsoft.com/en-us/dotnet/standard/net-standard.

If You Have Problems
--------------------

If you want to report a problem (bug, behavior, build, distribution, feature request, etc...) with the SDK built by this repository, please feel free to post a new issue and someone will try to help.

If you have "how-to" questions please post to one of the following resources:

- [Microsoft Q&A Forums](https://docs.microsoft.com/en-us/answers/topics/office-addins-dev.html) (tag: **office-addins-dev**)
- [Stack Overflow](http://stackoverflow.com) (tags: **openxml** or **openxml-sdk**)

Known Issues
------------

- On .NET Core and .NET 5, zip packages do not have a way to stream data. Thus, the working set can explode in certain situations. This is a [known issue](https://github.com/dotnet/runtime/issues/1544).
- On .NET Core, targeting .NET Framework 4.5+, and .NET 5, `System.Uri` will not parse invalid links. This causes an exception. A workaround in v2.12.0+ of OpenXml SDK is to use `OpenSettings.RelationshipErrorRewriter` to rewrite them to something that can be parsed. A discussion is available [here](https://github.com/dotnet/runtime/issues/26084) to enable something more robust in `System.IO.Packaging`.
- On .NET Framework, an `IsolatedStorageException` may be thrown under certain circumstances. This generally occurs when manipulating a large document in an environment with an AppDomain that does not have enough evidence. A sample with a workaround is available [here](/samples/IsolatedStorageExceptionWorkaround).

Documentation
-------------

The functionality of the specific classes in this version of the Open XML SDK is similar to version 2.5, therefore the [Open XML SDK 2.5 for Office](http://msdn.microsoft.com/en-us/library/office/bb448854.aspx) documentation available on MSDN is still accurate.

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  available for you to edit and review [in GitHub](https://github.com/OfficeDev/office-content).
