Aspose.Slides for .NET offers **Presentation** class that represents a presentation file. **Presentation** class can now also access **ODP** through Presentation constructor when the object is instantiated.

Below is the example of converting from ODP to PPT/PPTX.
## **Example**
```

 //Instantiate a Presentation object that represents a presentation file

using(PresentationEx pres = new PresentationEx("OpenOfficePresentation.odp"))

{

   //Saving the PPTX presentation to PPTX format

   pres.Save("ConvertedFromOdp",Aspose.Slides.Export.SaveFormat.Pptx);

}

``` 

Below is the example of converting from PPT/PPTX to ODP.
## **Example**
``` 

 //Instantiate a Presentation object that represents a presentation file

using (PresentationEx pres = new PresentationEx("ConversionFromPresentation.pptx"))

{

   //Saving the PPTX presentation to PPTX format

   pres.Save("ConvertedToOdp", Aspose.Slides.Export.SaveFormat.Odp);

}

```
