= Handling Microsoft PowerPoint (file format) =

This page discusses various available options for working with &quot;Microsoft PowerPoint&amp;quot;:http://en.wikipedia.org/wiki/Microsoft_PowerPoint#File_formats documents in your Qt application. Please also read the general considerations outlined on the [[Handling_Document_Formats | Handling Document Formats]] page.

One needs to distinguish between two different formats (this page deals with both of them):

table{width:95%;margin-left:2.5%}.<br />| |''. Legacy &quot;PowerPoint Presentation&amp;quot; format |''. &quot;Office Open XML Presentation&amp;quot; format |<br />| ''classification:'' | binary | XML-based |<br />| ''main filename extension:'' | {font:1em monospace}.ppt | {font-family:monospace}.pptx |<br />| ''main internet media type:'' | {font:0.9em monospace}application/vnd.ms-powerpoint | {font:0.9em monospace}application/vnd.openxmlformats-officedocument.presentationml.presentation |<br />| ''native format of PowerPoint:'' | until PowerPoint 2003 | since PowerPoint 2007 |

== Reading / Writing ==

=== Using PowerPoint itself ===

If you are exclusively targeting the Windows platform and Microsoft PowerPoint will be installed on all target machines, then you can use &quot;Qt’s ActiveX framework&amp;quot;:http://doc.qt.io/qt-4.8/activeqt.html to access PowerPoint’s .ppt and .pptx processing functionality through OLE automation. For an introductory code example (and a way to list the API provided by the PowerPoint COM object), consult &quot;this how to&amp;quot;:http://wiki.qt.io/Using_ActiveX_Object_in_QT (focuses on Microsoft Excel, but it works the same way for PowerPoint).

=== Using manual XML processing ===

Files using the XML-based (.pptx) format could be processed using Qt's XML handling classes (see [[Handling_Document_Formats | Handling Document Formats]]).
