DocumentFormat.OpenXml 3.3.0

Open XML SDK

Note

v3.0.0 refactors and addresses some technical debt while retaining source compatibility as much as possible. You should be able to update your package and recompile with limited changes. However, binary compatibility was not a goal and will break that for some changes which are documented. PRs that introduced such changes are marked with a breaking-change label and were added to a list to help migrating to v3.0.0.

Please see the v3.0.0 milestone for issues and PRs that are included. For discussions, please join us at this issue.

Important

The CI feed URL has changed as of 2 April, 2024. Please update to the new URL if using CI builds.

Downloads Build Status Backend Status

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.

Known Issues

  • On .NET Core and .NET 5 and following, ZIP packages do not have a way to stream data. Thus, the working set can explode in certain situations. This is a known issue.
  • 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.

Documentation

Please see Open XML SDK for the official documentation.

  • Added check to only seek on packages where it is supported (#1644)
  • If a malformed URI is encountered, the exception is now the same as v2.x (OpenXmlPackageException with an inner UriFormatException) (#1644)

3.0.0 - 2023-11-15

Added

  • Packages can now be saved on .NET Core and .NET 5+ if constructed with a path or stream (#1307).
  • Packages can now support malformed URIs (such as relationships with a URI such as mailto:person@)
  • Introduce equality comparers for OpenXmlElement (#1476)
  • IFeatureCollection can now be enumerated and has a helpful debug view to see what features are registered (#1452)
  • Add mime types to part creation (#1488)
  • DocumentFormat.OpenXml.Office.PowerPoint.Y2023.M02.Main namespace
  • DocumentFormat.OpenXml.Office.PowerPoint.Y2022.M03.Main namespace
  • DocumentFormat.OpenXml.Office.SpreadSheetML.Y2021.ExtLinks2021 namespace

Changed

  • When validation finds incorrect part, it will now include the relationship type rather than a class name
  • IDisposableFeature is now a part of the framework package and is available by default on a package or part.

Breaking Changes

  • .NET Standard 1.3 is no longer a supported platform. .NET Standard 2.0 is the lowest .NET Standard supported.
  • Core infrastructure is now contained in a new package DocumentFormat.OpenXml.Framework. Typed classes are still in DocumentFormat.OpenXml. This means that you may reference DocumentFormat.OpenXml and still compile the same types, but if you want a smaller package, you may rely on just the framework package.
  • Changed type of OpenXmlPackage.Package to DocumentFormat.OpenXml.Packaging.IPackage instead of System.IO.Packaging.Package with a similar API surface
  • EnumValue<T> now is used to box a struct rather than a System.Enum. This allows us to enable behavior on it without resorting to reflection
  • Methods on parts to add child parts (i.e. AddImagePart) are now implemented as extension methods off of a new marker interface ISupportedRelationship<T>
  • Part type info enums (i.e. ImagePartType) is no longer an enum, but a static class to expose well-known part types as structs. Now any method to define a new content-type/extension pair can be called with the new PartTypeInfo struct that will contain the necessary information.
  • OpenXmlPackage.CanSave is now an instance property (#1307)
  • Removed OpenXmlSettings.RelationshipErrorHandlerFactory and associated types and replaced with a built-in mechanism to enable this
  • IdPartPair is now a readonly struct rather than a class
  • Renamed PartExtensionProvider to IPartExtensionFeature and reduced its surface area to only two methods (instead of a full Dictionary<,>). The property to access this off of OpenXmlPackage has been removed, but may be accessed via Features.Get<IPartExtensionFeature>() if needed.
  • OpenXmlPart/OpenXmlContainer/OpenXmlPackage and derived types now have internal constructors (these had internal abstract methods so most likely weren't subclassed externally)
  • OpenXmlElementList is now a struct that implements IEnumerable<OpenXmlElement> and IReadOnlyList<OpenXmlElement> where available (#1429)
  • Individual implementations of OpenXmlPartReader are available now for each package type (i.e. WordprocessingDocumentPartReader, SpreadsheetDocumentPartReader, PresentationDocumentPartReader), and the previous TypedOpenXmlPartReader has been removed. (#1403)
  • Reduced unnecessary target frameworks for packages besides DocumentFormat.OpenXml.Framework (#1471)
  • Changed some spelling issues for property names (#1463, #1444)
  • Model3D now represents the modified xml element tag name am3d.model3d (Previously am3d.model3D)
  • Removed DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData.PivotCacheHasRichValuePivotCacheRichInfo
  • Removed DocumentFormat.OpenXml.Office.SpreadSheetML.Y2022.PivotRichData.RichDataPivotCacheGuid
  • Removed unused SchemaAttrAttribute (#1316)
  • Removed unused ChildElementInfoAttribute (#1316)
  • Removed OpenXmlSimpleType.TextValue. This property was never meant to be used externally (#1316)
  • Removed obsolete validation logic from v1 of the SDK (#1316)
  • Removed obsoleted methods from 2.x (#1316)
  • Removed mutable properties on OpenXmlAttribute and marked as readonly (#1282)
  • Removed OpenXmlPackage.Close in favor of Dispose (#1373)
  • Removed OpenXmlPackage.SaveAs in favor of Clone (#1376)

2.20.0

Added

  • Added DocumentFormat.OpenXml.Office.Drawing.Y2022.ImageFormula namespace
  • Added DocumentFormat.OpenXml.Office.Word.Y2023.WordML.Word16DU namespace

Changed

  • Marked OpenXmlSimpleType.TextValue as obsolete. This property was never meant to be used externally (#1284)
  • Marked OpenXmlPackage.Package as obsolete. This will be an implementation detail in future versions and won't be accessible (#1306)
  • Marked OpenXmlPackage.Close as obsolete. This will be removed in a later release, use Dispose instead (#1371)
  • Marked OpenXmlPackage.SaveAs as obsolete as it will be removed in a future version (#1378)

Fixed

  • Fixed incorrect file extensions for vbaProject files (#1292)
  • Fixed incorrect file extensions for ImagePart (#1305)
  • Fixed incorrect casing for customXml (#1351)
  • Fixed AddEmbeddedPackagePart to allow correct extensions for various content types (#1388)
