• "Convert presentation to PDF"
• "Extract slides", "presentation template"

Core Workflows

1. Reading/Analyzing Presentations

Extract to markdown:

Copypython -m markitdown presentation.pptx

Access raw XML:

Copyunzip -o presentation.pptx -d pptx_extracted
ls pptx_extracted/ppt/slides/  # Individual slide XML

2. Creating Presentations

Using python-pptx:

Copyfrom pptx import Presentation
from pptx.util import Inches, Pt
from pptx.enum.text import PP_ALIGN
from pptx.dml.color import RgbColor

prs = Presentation()

# Add title slide
title_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(title_layout)
title = slide.shapes.title
subtitle = slide.placeholders[1]

title.text = "Presentation Title"
subtitle.text = "Subtitle Here"

# Add content slide
content_layout = prs.slide_layouts[1]
slide = prs.slides.add_slide(content_layout)
slide.shapes.title.text = "Slide Title"

# Add bullet points
body = slide.placeholders[1]
tf = body.text_frame
tf.text = "First bullet point"

p = tf.add_paragraph()
p.text = "Second bullet point"
p.level = 0

p = tf.add_paragraph()
p.text = "Sub-bullet"
p.level = 1

prs.save('output.pptx')

3. Adding Visual Elements

Images:

Copyfrom pptx.util import Inches

slide = prs.slides.add_slide(prs.slide_layouts[6])  # Blank slide
slide.shapes.add_picture(
    'image.png',
    left=Inches(1),
    top=Inches(1),
    width=Inches(4)
)

Tables:

Copyfrom pptx.util import Inches

rows, cols = 3, 4
left, top = Inches(1), Inches(2)
width, height = Inches(8), Inches(2)

table = slide.shapes.add_table(rows, cols, left, top, width, height).table

# Set column headers
table.cell(0, 0).text = 'Header 1'
table.cell(0, 1).text = 'Header 2'

# Fill data
for row in range(1, rows):
    for col in range(cols):
        table.cell(row, col).text = f'R{row}C{col}'

Charts:

Copyfrom pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE

chart_data = CategoryChartData()
chart_data.categories = ['Q1', 'Q2', 'Q3', 'Q4']
chart_data.add_series('Sales', (19.2, 21.4, 16.7, 28.0))

x, y, cx, cy = Inches(2), Inches(2), Inches(6), Inches(4)
slide.shapes.add_chart(
    XL_CHART_TYPE.COLUMN_CLUSTERED, x, y, cx, cy, chart_data
)

4. Styling

Text formatting:

Copyfrom pptx.util import Pt
from pptx.dml.color import RgbColor

paragraph = shape.text_frame.paragraphs[0]
run = paragraph.runs[0]

run.font.name = 'Arial'
run.font.size = Pt(24)
run.font.bold = True
run.font.color.rgb = RgbColor(0x14, 0x14, 0x13)  # Dark

Slide background:

Copyfrom pptx.dml.color import RgbColor
from pptx.enum.dml import MSO_THEME_COLOR

background = slide.background
fill = background.fill
fill.solid()
fill.fore_color.rgb = RgbColor(0xFA, 0xF9, 0xF5)  # Light cream

5. Design Palettes

6. Converting to PDF/Images

To PDF:

Copy# Using LibreOffice
libreoffice --headless --convert-to pdf presentation.pptx

# Using unoconv
unoconv -f pdf presentation.pptx

To images:

Copy# Using pdftoppm (convert to PDF first, then images)
libreoffice --headless --convert-to pdf presentation.pptx
pdftoppm presentation.pdf slide -png

7. Template-Based Creation

Copyfrom pptx import Presentation

# Load template
prs = Presentation('template.pptx')

# Get available layouts
for i, layout in enumerate(prs.slide_layouts):
    print(f'{i}: {layout.name}')

# Use specific layout
slide = prs.slides.add_slide(prs.slide_layouts[2])

# Replace placeholder text
for shape in slide.placeholders:
    if shape.has_text_frame:
        if 'Title' in shape.text:
            shape.text = 'New Title'

Dependencies

Copypip install python-pptx markitdown
brew install libreoffice poppler  # For PDF conversion
