This page discusses various available options for working with Microsoft PowerPoint documents in your Qt application. Please also read the general considerations outlined on the Handling Document Formats page.

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


Legacy "PowerPoint Presentation" format "Office Open XML Presentation" format
classification: binary XML-based
main filename extension: .ppt .pptx
main internet media type: application/vnd.ms-powerpoint application/vnd.openxmlformats-officedocument.presentationml.presentation
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 Qt’s ActiveX framework 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 this how to (focuses on Microsoft Excel, but it works the same way for PowerPoint).


DLL file name COM object name platforms license
Microsoft PowerPoint ? PowerPoint.Application Windows commercial

Using independent parser/writer libraries

API .ppt .pptx reading writing platforms license

Using manual XML processing

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

Using batch conversion tools
