Convert PowerPoint Presentations to Word Documents in Python

Overview

This article provides a solution for developers on converting PowerPoint and OpenDocument presentations to Word documents using Aspose.Slides for Python via .NET and Aspose.Words for Python via .NET. The step-by-step guide walks you through every stage of the conversion process.

Convert a Presentation to a Word Document

Follow the instructions below to convert a PowerPoint or OpenDocument presentation to a Word document:

1. Instantiate the Presentation class and load a presentation file.
2. Instantiate the Document and DocumentBuilder classes to generate a Word document.
3. Set the page size for the Word document to match that of the presentation using the DocumentBuilder.page_setup property.
4. Set margins in the Word document using the DocumentBuilder.page_setup property.
5. Go through all the presentation slides using the Presentation.slides property.
   • Generate a slide image using the get_image method from the Slide class and save it to a memory stream.
   • Add the slide image to the Word document using the insert_image method from the DocumentBuilder class.
6. Save the Word document to a file.

Let’s say we have a presentation “sample.pptx” that looks like this:

The following Python code example demonstrates how to convert the PowerPoint presentation to a Word document:

import aspose.slides as slides
import aspose.words as words

# Load a presentation file.
with slides.Presentation("sample.pptx") as presentation:

    # Create Document and DocumentBuilder objects.
    document = words.Document()
    builder = words.DocumentBuilder(document)

    # Set the page size in the Word document.
    slide_size = presentation.slide_size.size
    builder.page_setup.page_width = slide_size.width
    builder.page_setup.page_height = slide_size.height

    # Set margins in the Word document.
    builder.page_setup.left_margin = 0
    builder.page_setup.right_margin = 0
    builder.page_setup.top_margin = 0
    builder.page_setup.bottom_margin = 0

    scale_x = 2
    scale_y = 2

    # Go through all the presentation slides.
    for slide in presentation.slides:

        # Generate a slide image and save it to a memory stream.
        with slide.get_image(scale_x, scale_y) as image:
            image_stream = BytesIO()
            image.save(image_stream, slides.ImageFormat.PNG)

        # Add the slide image to the Word document.
        image_stream.seek(0)
        image_width = builder.page_setup.page_width
        image_height = builder.page_setup.page_height
        builder.insert_image(image_stream.read(), image_width, image_height)

        builder.insert_break(words.BreakType.PAGE_BREAK)

    # Save the Word document to a file.
    document.save("output.docx")
