PPTX creation, editing, and analysis

Overview

A user may ask you to create, edit, or analyze the contents of a .pptx file. A .pptx file is essentially a ZIP archive containing XML files and other resources that you can read or edit. You have different tools and workflows available for different tasks.

Reading and analyzing content

Text extraction

If you just need to read the text contents of a presentation, you should convert the document to markdown:

# Convert document to markdown
python -m markitdown path-to-file.pptx

Raw XML access

You need raw XML access for: comments, speaker notes, slide layouts, animations, design elements, and complex formatting. For any of these features, you'll need to unpack a presentation and read its raw XML contents.

Unpacking a file

`python ooxml/scripts/unpack.py <office_file> <output_dir>`

**Note**: The unpack.py script is located at `skills/pptx/ooxml/scripts/unpack.py` relative to the project root. If the script doesn't exist at this path, use `find . -name "unpack.py"` to locate it.

Key file structures

• `ppt/presentation.xml` - Main presentation metadata and slide references
• `ppt/slides/slide{N}.xml` - Individual slide contents (slide1.xml, slide2.xml, etc.)
• `ppt/notesSlides/notesSlide{N}.xml` - Speaker notes for each slide
• `ppt/comments/modernComment_*.xml` - Comments for specific slides
• `ppt/slideLayouts/` - Layout templates for slides
• `ppt/slideMasters/` - Master slide templates
• `ppt/theme/` - Theme and styling information
• `ppt/media/` - Images and other media files

Typography and color extraction

**When given an example design to emulate**: Always analyze the presentation's typography and colors first using the methods below: 1. **Read theme file**: Check `ppt/theme/theme1.xml` for colors (`<a:clrScheme>`) and fonts (`<a:fontScheme>`) 2. **Sample slide content**: Examine `ppt/slides/slide1.xml` for actual font usage (`<a:rPr>`) and colors 3. **Search for patterns**: Use grep to find color (`<a:solidFill>`, `<a:srgbClr>`) and font references across all XML files

Creating a new PowerPoint presentation **without a template**

When creating a new PowerPoint presentation from scratch, use the **html2pptx** workflow to convert HTML slides to PowerPoint with accurate positioning.

Design Principles

**CRITICAL**: Before creating any presentation, analyze the content and choose appropriate design elements: 1. **Consider the subject matter**: What is this presentation about? What tone, industry, or mood does it suggest? 2. **Check for branding**: If the user mentions a company/organization, consider their brand colors and identity 3. **Match palette to content**: Select colors that reflect the subject 4. **State your approach**: Explain your design choices before writing code

**Requirements**:

• ✅ State your content-informed design approach BEFORE writing code
• ✅ Use web-safe fonts only: Arial, Helvetica, Times New Roman, Georgia, Courier New, Verdana, Tahoma, Trebuchet MS, Impact
• ✅ Create clear visual hierarchy through size, weight, and color
• ✅ Ensure readability: strong contrast, appropriately sized text, clean alignment
• ✅ Be consistent: repeat patterns, spacing, and visual language across slides

Color Palette Selection

**Choosing colors creatively**:

• **Think beyond defaults**: What colors genuinely match this specific topic? Avoid autopilot choices.
• **Consider multiple angles**: Topic, industry, mood, energy level, target audience, brand identity (if mentioned)
• **Be adventurous**: Try unexpected combinations - a healthcare presentation doesn't have to be green, finance doesn't have to be navy
• **Build your palette**: Pick 3-5 colors that work together (dominant colors + supporting tones + accent)
• **Ensure contrast**: Text must be clearly readable on backgrounds

**Example color palettes** (use these to spark creativity - choose one, adapt it, or create your own):
