## Convert PPSX to OTP in Python

[Aspose.Slides for Python via Java](/slides/python-java/) can convert a PowerPoint Slide Show (`.ppsx`) to an OpenDocument Presentation Template (`.otp`) without Microsoft PowerPoint or LibreOffice. The OTP output can serve as a reusable starting point for presentations in applications that support the OpenDocument format.

Load the source file with `Presentation`, then call `save` with `SaveFormat.Otp`. Aspose.Slides writes the supported slide content, layouts, and formatting to the template file.

## How to Convert PPSX to OTP in Python

Create a `Presentation` from the source PPSX file and save it with `SaveFormat.Otp`.

### Python code for converting PPSX to OTP

```python
presentation = Presentation("presentation.ppsx")
try:
    presentation.save("presentation.otp", SaveFormat.Otp)
finally:
    presentation.dispose()
```

## Steps to Convert PPSX to OTP in Python

The conversion loads the PowerPoint slide show and writes its content to an OpenDocument presentation template.

Install [Aspose.Slides for Python via Java](/slides/python-java/).

Configure JPype and make the Aspose.Slides package available to your Python project.

Create a `Presentation` from the source `.ppsx` file.

Call `save` with `SaveFormat.Otp` and an `.otp` output path.
