## Convert PPSX to PPT in Python

[Aspose.Slides for Python via Java](/slides/python-java/) can convert a PowerPoint Slide Show (`.ppsx`) to the PowerPoint 97-2003 Presentation (`.ppt`) format without Microsoft PowerPoint. The resulting PPT file opens as an editable presentation rather than directly as a slide show.

Load the source file with `Presentation`, then call `save` with `SaveFormat.Ppt`. Because PPT is an older format, features that it does not support cannot be represented in the output.

## How to Convert PPSX to PPT in Python

Load the source PPSX file into a `Presentation`, then save it with `SaveFormat.Ppt`.

### Python code for converting PPSX to PPT

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

## Steps to Convert PPSX to PPT in Python

The conversion loads the Open XML PowerPoint slide show and writes its content in the legacy PPT presentation format.

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.Ppt` and a `.ppt` output path.
