Open XML FormatsOpen XML SDK overviewOpen XML SDK architecture + roadmapLots! of demosOpen XML SDK toolsResources + linksQ&A

OPEN XML FORMATSWhat are they?

Open XML Formats Architecture

Users see a single file

MyDoc.docx

Developers see a zip file with xml parts

Document properties

File container

Comments

WordML/SpreadsheetML, etc.

Custom-defined XML

Images, video, sound

Styles

Charts

Default format in Office 2007 and 2010

Word (.docx)Excel (.xlsx)PowerPoint (.pptx)

Open XML is an ISO standardDocument Parts

Most parts are XML

Office Open XML Formats

Allows developers access to Office files without the need of the Office applications Current toolset for Open XML

WinZip, MSXML & Notepad System.IO.Packaging, System.XML, & LINQ

Future of Open XML development:Open XML SDK

OPEN XML SDKWhat it is and what it’s not?

Open XML SDK Overview

Allows you to create and modify Open XML documents

SDK will support both Office 2007 SP2 and Office 2010 file formats

Based on .NET (C# and VB)Compatible with LINQ

Provides a unified platform for solutionsConsistent client and server solutions

This SDK does NOTReplace Office application Object ModelsPerform layout + recalculation tasksPerform file conversions to other formats, like PDF or XPS

Open XML SDK Road Map

Version 1.0 of the SDKProvides part level manipulationFinal bits released June 2008“Go-Live” license – Free to use and build/deploy solutions

Version 2.0 of the SDKProvides content level manipulation1st CTP released September 20082nd CTP released April 20093rd CTP released August 2009Final release around same time Office 2010 ships

Key Takeaways

FastIntellisense really helpsStarting from a template is always easiestEasy to search for specific contentManipulation easy with access to strongly typed objectsUse the tools…they help!

I will talk more about the tools later on

Microsoft Confidential

Key Takeaways

LINQ to SQL…why not LINQ to Excel?LINQ built into SDK makes querying easy

Manipulating Content Within Open XMLSanitizing a Word document on the server

Key Takeaways

Again, fast!Personally identifiable information removed without client

Multiple types of solutions easily integrated into SharePoint

Workflow basedCustom action basedRibbon based

OPEN XML SDK TOOLSUse the tools!

Open XML SDK Tools

SDK provides the following tools1. Open XML Diff 2. Class Explorer3. Document Reflector

Open XML DiffCompare differences in two Open XML files

Class Explorer Allows developers to navigate Open XML standard as it relates to the SDK

Document ReflectorAutomatically generates Open XML SDK code based on document

Open XML Power Tools

A set of 30+ cmdlets that create and modify Open XML documents

Removing comments, accepting tracked revisions, etc.

Supports the PowerShell piping architecture Documents are piped from cmdlet to cmdlet as objects

Built on Open XML SDK Available on CodePlex

Key Takeaways

IT and developers can perform batch scripts using PowerToolsReleased as open source, under the Microsoft Public License (Ms-PL)Works with PowerShellProvides a set of rich functionalities to build and modify rich Open XML Formats

VSTO Power Tools

Open and edit Open XML documents directly in Visual Studio
