Powerpoint ppt to ODP

Aspose.Slides Product Family
1

Hello, I am trying to export a ppt to odp format with the following code in .net.


Dim pres As New Aspose.Slides.Presentation(“powerpoint.ppt”)
pres.Save(“powerpoint.odp”, Aspose.Slides.Export.SaveFormat.Odp)

I get an exception that says the following:

Aspose.Slides.PptException: This export format is not implemented for PPT yet.

Am I using the wrong code or is this still true that I cannot save or convert a powerpoint
to an opendocument presentation. Also does this apply to PPTX to ODP too?

Thanks for your time!

Hi Vanessa,


I like to share that the the support for working with ODP format is available in PresentationEx class. You need to access the PPT using PresentationEx class and save that as ODP. Please use the following sample code on your end to serve the purpose. Please try using Aspose.Slides for .NET 8.2.0 on your end in this regard.

PresentationEx pres=new PresentationEx(path+“powerpoint.ppt”);
pres.Save(path+“testODP.odp”,SaveFormat.Odp);


Many Thanks,

Hi Mudassir,

I tried the code with the .NET 8.2.0 assembly as you outlined and ran into varying exceptions. I am attaching a zip file that contains the files and an excel file of the filename and the corresponding exception. In addition, most of the presentations that do not throw an exception during export/conversion, do show a message about the file needing to be repaired when I open in Microsoft Powerpoint. USDAFoodsUpdate.pptx is an example of this.

Thanks for the help!
