PPTX Toolkit

Create and edit PowerPoint decks with python-pptx (MIT licensed).

When to Use

Generate a .pptx deck or pitch presentation from content.
Edit an existing presentation (add slides, text, images, tables, notes).
Extract text or speaker notes from a .pptx.

To convert a deck to Markdown for analysis, use markitdown-converter. Use this skill to author or edit .pptx files.

Setup

pip install python-pptx

Create a deck

from pptx import Presentation
from pptx.util import Inches, Pt

prs = Presentation()

# Title slide (layout 0)
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Q2 Review"
slide.placeholders[1].text = "Prepared by the team"

# Title + content (layout 1) with bullets
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Highlights"
body = slide.placeholders[1].text_frame
body.text = "Revenue up 15%"
for line in ["Email Course led growth", "Workflow Kit steady"]:
    p = body.add_paragraph()
    p.text = line
    p.level = 1

# Blank slide (layout 6) with an image + speaker notes
slide = prs.slides.add_slide(prs.slide_layouts[6])
slide.shapes.add_picture("chart.png", Inches(1), Inches(1), width=Inches(8))
slide.notes_slide.notes_text_frame.text = "Walk through the chart for 30s."

prs.save("review.pptx")

Read / extract

from pptx import Presentation
prs = Presentation("review.pptx")
for i, slide in enumerate(prs.slides, 1):
    for shape in slide.shapes:
        if shape.has_text_frame:
            print(i, shape.text_frame.text)
    if slide.has_notes_slide:
        print("notes:", slide.notes_slide.notes_text_frame.text)

Notes & Limits

Available layouts depend on the template (prs.slide_layouts); indices 0/1/6 are typical for title / title+content / blank in the default template.
python-pptx does not render slides to images/PDF — use LibreOffice/PowerPoint for that.
