In a PowerPoint document, the footer is an area located at the bottom of each slide, typically containing textual information such as page numbers, dates, authors, and more. By adding a footer, you can give your slides a professional look and provide important information. Modifying the footer allows you to adjust the displayed content, style, and position to meet specific needs or styles. Removing the footer can clear the bottom content when extra information is not needed or to maintain a clean appearance. This article will introduce how to use Spire.Presentation for Python to add, modify, or remove footers in PowerPoint documents within a Python project.

slide = presentation.Slides[0]

# Iterate through the shapes on the slide
for shape in slide.Shapes:
   # Check if the shape is a placeholder
   if shape.Placeholder is not None:
       # Get the placeholder type
       type = shape.Placeholder.Type

       # If it is a footer placeholder
       if type == PlaceholderType.Footer:
           # Convert the shape to IAutoShape type
            autoShape = shape if isinstance(shape, IAutoShape) else None
            if autoShape is not None:
                # Set the text content to "E-ICEBLUE"
                autoShape.TextFrame.Text = "E-ICEBLUE"

                # Modify the text font
                change_font(autoShape.TextFrame.Paragraphs[0])
       
       # If it is a slide number placeholder
       if type == PlaceholderType.SlideNumber:
            # Convert the shape to IAutoShape type
            autoShape = shape if isinstance(shape, IAutoShape) else None
            if autoShape is not None:
                # Modify the text font
                change_font(autoShape.TextFrame.Paragraphs[0])

Why Choose Spire.Doc for Python to Align Text?​

Before diving into code, let’s clarify why Spire.Doc is a top choice for text alignment tasks:​

• Full Alignment Support: Natively supports all standard alignment types (Left, Right, Center, Justify) for paragraphs.​
• No Microsoft Word Dependency: Runs independently - no need to install Word on your machine.​
• High Compatibility: Works with .docx, .doc, and other Word formats, ensuring your aligned documents open correctly across devices.​
• Fine-Grained Control: Adjust alignment for entire paragraphs or table cells.​

Core Text Alignment Types in Spire.Doc​

Spire.Doc uses the HorizontalAlignment enum to define text alignment. The most common values are:​

• HorizontalAlignment.Left: Aligns text to the left margin (default).​
• HorizontalAlignment.Right: Aligns text to the right margin.​
• HorizontalAlignment.Center: Centers text horizontally between margins.​
• HorizontalAlignment.Justify: Adjusts text spacing so both left and right edges align with margins.​
• HorizontalAlignment.Distribute: Adjusts character spacing (adds space between letters) and word spacing to fill the line.

Below, we’ll cover how to programmatically set paragraph alignment (left, right, center, justified, and distributed) in Word using Python

Step-by-Step: Align Text in Word in Python

Here are the actionable steps to generate a Word document with 5 paragraphs, each using a different alignment style.

Step 1: Install Spire.Doc for Python

Open your terminal/command prompt​, and then run the following command to install the latest version:

pip install Spire.Doc

Step 2: Import Required Modules

Import the core classes from Spire.Doc. These modules let you create documents, sections, paragraphs, and configure formatting:

from spire.doc import *
from spire.doc.common import *

Step 3: Create a New Word Document

Initialize a Document instance that represents your empty Word file:

# Create a Document instance
doc = Document()

Step 4: Add a Section to the Document

Word documents organize content into sections (each section can have its own margins, page size, etc.). We’ll add one section to hold our paragraphs:

# Add a section to the document
section = doc.AddSection()

Step 5: Add Paragraphs with Different Alignments

A section contains paragraphs, and each paragraph’s alignment is controlled via the HorizontalAlignment enum. We’ll create 5 paragraphs, one for each alignment type.

1. Left Align in Python

Left alignment is the default for most text (text aligns to the left margin).

# Left aligned text
paragraph1 = section.AddParagraph()
paragraph1.AppendText("This is left-aligned text.")
paragraph1.Format.HorizontalAlignment = HorizontalAlignment.Left

2. Right Align Text in Python

Right alignment is useful for dates, signatures, or page numbers (text aligns to the right margin).

# Right aligned text
paragraph2 = section.AddParagraph()
paragraph2.AppendText("This is right-aligned text.")
paragraph2.Format.HorizontalAlignment = HorizontalAlignment.Right

3. Center Text in Python

Center alignment works well for titles or headings (text centers between left and right margins). Use to center text in Python:

# Center aligned text
paragraph3 = section.AddParagraph()
paragraph3.AppendText("This is center-aligned text.")
paragraph3.Format.HorizontalAlignment = HorizontalAlignment.Center

4. Justify Text in Python

Justified text aligns both left and right margins (spaces between words are adjusted for consistency). Ideal for formal documents like essays or reports.

# Justified
paragraph4 = section.AddParagraph()
paragraph4.AppendText("This is justified text.")
paragraph4.Format.HorizontalAlignment = HorizontalAlignment.Justify

Note: Justified alignment is more visible with longer text - short phrases may not show the spacing adjustment.

5. Distribute Text in Python

Distributed alignment is similar to justified, but evenly distributes single-line text (e.g., unevenly spaced words or short phrases).

# Distributed
Paragraph5 = section.AddParagraph()
Paragraph5.AppendText("This is evenly distributed text.")
Paragraph5.Format.HorizontalAlignment = HorizontalAlignment.Distribute

Step 6: Save and Close the Document

Finally, save the document to a specified path and close the Document instance to free resources:

# Save the document
document.SaveToFile("TextAlignment.docx", FileFormat.Docx2016)
# Close the document to release memory
document.Close()

Output:

Pro Tip: Spire.Doc for Python also provides interfaces to align tables in Word or align text in table cells.

FAQs About Python Text Alignment

Q1: Is Spire.Doc for Python free?

A: Spire.Doc offers a free version with limitations. For full functionality, you can request a 30-day trial license here.

Q2: Can I set text alignment for existing Word documents

A: Yes. Spire.Doc lets you load existing documents and modify text alignment for specific paragraphs. Here’s a quick example:

from spire.doc import *

# Load an existing document
doc = Document()
doc.LoadFromFile("ExistingDocument.docx")

# Get the first section and first paragraph
section = doc.Sections[0]
paragraph = section.Paragraphs[0]

# Change alignment to center
paragraph.Format.HorizontalAlignment = HorizontalAlignment.Center

# Save the modified document
doc.SaveToFile("UpdatedDocument.docx", FileFormat.Docx2016)
doc.Close()

Q3: Can I apply different alignments to different parts of the same paragraph?

A: No. Text alignment is a paragraph-level setting in Word, not a character-level setting. This means all text within a single paragraph must share the same alignment (left, right, center, etc.).

If you need mixed alignment in the same line, you’ll need to use a table with invisible borders.

Q4: Can Spire.Doc for Python handle other text formatting?

A: Absolutely! Spire.Doc lets you combine alignment with other formatting like fonts, line spacing, bullet points, and more.

Conclusion

Automating Word text alignment with Python and Spire.Doc saves time, reduces human error, and ensures consistency across documents. The code example provided offers a clear template for implementing left, right, center, justified, and distributed alignment, and adapting it to your needs is as simple as modifying the text or adding more formatting rules.
