## Convert PPSX to OTP in Python

[*Aspose.Slides for Python via .NET*](/slides/python-net/) lets you convert a PowerPoint Open XML Slide Show in PPSX format to an OpenDocument Presentation Template in OTP format. Load the PPSX file into a `Presentation` instance and save it by using `SaveFormat.OTP`.

The API preserves presentation content and formatting during conversion and does not require Microsoft PowerPoint. Test the conversion in the free [online app](https://products.aspose.app/slides/conversion) or integrate the Python API into your application.

Install the library from [PyPI](https://pypi.org/project/aspose-slides/) by using the following command:

### Console/Terminal

```console
pip install aspose-slides
```
