Rearrange Slides in a PowerPoint Document in Python

To reorder the slides in PowerPoint, two Presentation objects were created - one for loading the original document, and one for creating a new document. By copying the slides from the original document to the new one in the desired sequence, the slide order could be easily rearranged.

The following are the steps to rearrange slides in a PowerPoint document using Python.

• Create a Presentation object.
• Load a PowerPoint document using Presentation.LoadFromFile() method.
• Specify the slide order within a list.
• Create another Presentation object for creating a new presentation.
• Add the slides from the original document to the new presentation in the specified order using Presentation.Slides.AppendBySlide() method.
• Save the new presentation to a PPTX file using Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create a Presentation object
presentation = Presentation()

# Load a PowerPoint file
presentation.LoadFromFile("C:\\Users\\Administrator\\Desktop\\input.pptx")

# Specify the new slide order within a list
newSlideOrder = [4,2,1,3]

# Create another Presentation object
new_presentation =  Presentation()

# Remove the default slide
new_presentation.Slides.RemoveAt(0)

# Iterate through the list
for i in range(len(newSlideOrder)):

    # Add the slides from the original PowerPoint file to the new PowerPoint document in the new order
    new_presentation.Slides.AppendBySlide(presentation.Slides[newSlideOrder[i] - 1])

# Save the new presentation to file
new_presentation.SaveToFile("output/NewOrder.pptx", FileFormat.Pptx2019)

# Dispose resources
presentation.Dispose()
new_presentation.Dispose()
