Run3 Extract PPTX Content and Structure

When to use this skill

• When you need to read the actual content from .pptx files
• Before sorting presentations into subject folders
• When filenames don't clearly indicate the presentation topic

How to extract PPTX content

Using markitdown for structured extraction

python -m markitdown input.pptx > output.md

Using Python with python-pptx

from pptx import Presentation

def extract_pptx_content(pptx_path):
    prs = Presentation(pptx_path)
    content = []
    
    for slide_num, slide in enumerate(prs.slides, 1):
        slide_text = f"--- SLIDE {slide_num} ---\n"
        
        for shape in slide.shapes:
            if hasattr(shape, "text"):
                slide_text += shape.text + "\n"
        
        content.append(slide_text)
    
    return "\n".join(content)

Key information to extract

1. Title slide: Main topic of presentation
2. Slide titles: Each slide's heading indicates content areas
3. Body text: Bullet points and paragraphs contain subject keywords
4. First 5 slides: Usually establish the presentation's main subject

Subject indicators to look for

• Look for the same keyword patterns as PDF extraction
• Note technical terms, proper nouns, and repeated concepts
• Section headers often reveal the subject area

Store extracted content

Keep the full extracted text for analysis during subject classification.
