Convert presentations to markdown

To convert presentations (like PowerPoint or Google Slides) to Markdown, you typically want to extract the slide content—titles, bullet points, images, and other text—and format them into Markdown syntax. Here’s a general approach and some tips on how to do this:

Manual Conversion Approach

1. Open your presentation in PowerPoint, Google Slides, or another tool.

2. Go slide by slide and copy the text content.

3. Format the content in Markdown:

   • Slide titles → Use headers (#, ##, etc.)

   • Bullet points → Use - or * for lists

   • Numbered lists → Use 1., 2., etc.

   • Images → Use ![alt text](image_url_or_path)

   • Emphasis → Use *italic* or **bold**

   • Code snippets (if any) → Use backticks `code` or code blocks

Example:

markdown
CopyEdit
# Slide 1 Title

- Bullet point 1
- Bullet point 2
- Bullet point 3

## Slide 2 Title

1. First item
2. Second item

Automated Tools & Methods

• Pandoc: Converts PowerPoint (.pptx) files to Markdown. Example command:

  bash
  CopyEdit
  pandoc presentation.pptx -t markdown -o presentation.md
  

  This works best with simple slides focused on text.

• Google Slides + Google Docs + Markdown: Export slides as text or outline, then format into Markdown.

• Python Libraries: You can use python-pptx to parse .pptx files and extract content programmatically, then generate Markdown output.

Sample Python snippet using python-pptx to extract text and convert to Markdown

python
CopyEdit
from pptx import Presentation

prs = Presentation('presentation.pptx')
md = ""

for slide in prs.slides:
    # Get slide title
    title = slide.shapes.title.text if slide.shapes.title else ""
    if title:
        md += f"# {title}nn"

    for shape in slide.shapes:
        if shape.has_text_frame and shape != slide.shapes.title:
            for paragraph in shape.text_frame.paragraphs:
                # Assuming bullet points:
                if paragraph.level == 0:
                    md += f"- {paragraph.text}n"
                else:
                    md += f"  {'  ' * (paragraph.level - 1)}- {paragraph.text}n"
    md += "n"

with open('presentation.md', 'w') as f:
    f.write(md)
