The title of a slide can be updated using the ISlide.Title property. The detailed steps are as follows.

• Create a Presentation instance.
• Load a PowerPoint PPTX or PPT document using Presentation.LoadFromFile() method.
• Get a specific slide of the document using Presentation.Slides[index] property.
• Update the title of the slide using ISlide.Title property.
• Save the result document using Presentation.SaveToFile() method.

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

# Create a Presentation object
ppt = Presentation()
# Load a PowerPoint document
ppt.LoadFromFile("Water Of Life.pptx")

# Get the second slide
slide = ppt.Slides[1]

# Update the title of the second slide
slide.Title = "Updated Title"

# Save the result document
ppt.SaveToFile("UpdateSlideTitle.pptx", FileFormat.Pptx2016)
ppt.Dispose()

Extract All Slide Titles from PowerPoint in Python

To extract all slide titles from a PowerPoint document, you first need to iterate through all slides in the document and all shapes on each slide. Then identify shapes with placeholder types like Title, CenteredTitle, or Subtitle. After that retrieve the text content from the identified shapes using the IAutoShape.TextFrame.Text property. The detailed steps are as follows.

• Create a Presentation instance.
• Load a PowerPoint PPTX or PPT document using Presentation.LoadFromFile() method.
• Create a list to store the extracted titles.
• Iterate through all slides in the document.
• For each slide, iterate through all shapes on it.
• Identify shapes with placeholder types such as Title, CenteredTitle, or Subtitle.
• Typecast the identified shapes to IAutoShape object.
• Retrieve the text content of the identified shapes using the IAutoShape.TextFrame.Text property and append them to the list.
• Save the content of the list to a text file.

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

# Load a PowerPoint document
ppt = Presentation()
ppt.LoadFromFile("Water of Life.pptx")

# Create a list to store the extracted slide titles
titles = []

# Iterate through all slides in the document
for slide in ppt.Slides:
    # Iterate through all shapes on each slide
    for shape in slide.Shapes:
        # Find the shapes with placeholder types such as Title, CenteredTitle, or Subtitle
        if shape.Placeholder is not None and shape.Placeholder.Type in [PlaceholderType.Title, PlaceholderType.CenteredTitle, PlaceholderType.Subtitle]:
            # Typecast the shape to IautoShape object
            auto_shape = shape if isinstance(shape, IAutoShape) else None
            if auto_shape is not None:
                # Add the text of the shape to the titles list
                titles.append(auto_shape.TextFrame.Text)

# Save the extracted slide titles to a text file
with open("AllTitles.txt", "w") as file:
    file.write("Extracted titles:\n")
    file.write("\n".join(titles))

ppt.Dispose()

• Merging PowerPoint Presentations with Consistent Design

Install Spire.PDF for Python

This scenario requires Spire.Presentation for Python and plum-dispatch v1.7.4. They can be easily installed in your Windows through the following pip command.

pip install Spire.Presentation

If you are unsure how to install, please refer to: How to Install Spire.Presentation for Python on Windows

Merging PowerPoint Presentations and Retain Their Designs

Merging PowerPoint presentations can be accomplished by reading slides from one presentation and adding them to another presentation. During the process of adding to the target presentation, developers can use Presentation.Slides.AppendBySlide(ISlide) method to add slides and retain the original design of the slides.

The detailed steps are as follows:

• Create two instances of Presentation class.
• Load two PowerPoint presentations using Presentation.LoadFromFile() method.
• Iterate through each slide in the second presentation and add them to the first presentation while keeping their design using Presentation.Slides.AppendBySlide() method.
• Save the first presentation using Presentation.SaveToFile() method.

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

# Create two instances of Presentation class
pres1 = Presentation()
pres2 = Presentation()

# Load two presentation files
pres1.LoadFromFile("Sample1.pptx")
pres2.LoadFromFile("Sample2.pptx")

# Iterate through the slides of the second presentation
for slide in pres2.Slides:
    # Add each slides to the first presentation and keep the original design
    pres1.Slides.AppendBySlide(slide)

# Save the first presentation
pres1.SaveToFile("output/MergePresentations.pptx", FileFormat.Pptx2016)
pres1.Dispose()
pres2.Dispose()

Merging PowerPoint Presentations with Consistent Design

Developers can also use Presentation.Slides.AppendByMaster(slide Islide, master IMasterSlide) method to insert slides into the target presentation and change the design of the slides to the design of the target presentation. This allows for merging presentations and ensuring a consistent design.

The detailed stops are as follows:

• Create two instances of Presentation class.
• Load two PowerPoint presentations using Presentation.LoadFromFile() method.
• Iterate through each slide in the second presentation and add them to the first presentation while changing their design to the design of the first presentation using Presentation.Slides.AppendByMaster() method.
• Save the first presentation using Presentation.SaveToFile() method.

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

# Create two instances of Presentation class
pres1 = Presentation()
pres2 = Presentation()

# Load two presentation files
pres1.LoadFromFile("Sample1.pptx")
pres2.LoadFromFile("Sample2.pptx")

# Iterate through each slide in the second presentation
for slide in pres2.Slides:
    # Add each slide to the first presentation
    pres1.Slides.AppendByMaster(slide, pres1.Masters[0])

# Save the first presentation
pres1.SaveToFile("output/MergePresentationsDesign.pptx", FileFormat.Pptx2016)
pres1.Dispose()
pres2.Dispose()
