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.

Prerequisites

Python dependencies are resolved automatically by uv run — scripts declare them in PEP 723 headers. The workflows below also rely on:

Node.js packages — if node_modules/ is missing, run npm install in this skill directory once. This installs pptxgenjs and playwright, which drives Chromium/Chrome for HTML rendering (on macOS it uses system Chrome; elsewhere run npx playwright install chromium once if no browser is present). It also installs sharp, react, react-dom, and react-icons — html2pptx.js does not use these itself; they are provided for scripts you write during the html2pptx workflow (icon and gradient rasterization, see html2pptx.md)
LibreOffice (brew install --cask libreoffice) and poppler (brew install poppler) — converting presentations to PDF/images for thumbnails and visual validation (soffice, pdftoppm)

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
uv run --with 'markitdown[pptx]' 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

uv run ooxml/scripts/unpack.py <office_file> <output_dir>

Note: Run this from the pptx skill directory, where the script is at ooxml/scripts/unpack.py. If it isn't found there, 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:

Read theme file: Check ppt/theme/theme1.xml for colors (<a:clrScheme>) and fonts (<a:fontScheme>)
Sample slide content: Examine ppt/slides/slide1.xml for actual font usage (<a:rPr>) and colors
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:

Consider the subject matter: What is this presentation about? What tone, industry, or mood does it suggest?
Check for branding: If the user mentions a company/organization, consider their brand colors and identity
Match palette to content: Select colors that reflect the subject
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):

Classic Blue: Deep navy (#1C2833), slate gray (#2E4053), silver (#AAB7B8), off-white (#F4F6F6)
Teal & Coral: Teal (#5EA8A7), deep teal (#277884), coral (#FE4447), white (#FFFFFF)

Visual Details Options

Geometric Patterns:

Diagonal section dividers instead of horizontal
Asymmetric column widths (30/70, 40/60, 25/75)
Rotated text headers at 90° or 270°
Circular/hexagonal frames for images
Triangular accent shapes in corners
Overlapping shapes for depth

Border & Frame Treatments:

Thick single-color borders (10-20pt) on one side only
Double-line borders with contrasting colors
Corner brackets instead of full frames
L-shaped borders (top+left or bottom+right)
Underline accents beneath headers (3-5pt thick)

Typography Treatments:

Extreme size contrast (72pt headlines vs 11pt body)
All-caps headers with wide letter spacing
Numbered sections in oversized display type
Monospace (Courier New) for data/stats/technical content
Condensed fonts (Arial Narrow) for dense information
Outlined text for emphasis

Chart & Data Styling:

Monochrome charts with single accent color for key data
Horizontal bar charts instead of vertical
Dot plots instead of bar charts
Minimal gridlines or none at all
Data labels directly on elements (no legends)
Oversized numbers for key metrics

Layout Innovations:

Full-bleed images with text overlays
Sidebar column (20-30% width) for navigation/context
Modular grid systems (3×3, 4×4 blocks)
Z-pattern or F-pattern content flow
Floating text boxes over colored shapes
Magazine-style multi-column layouts

Background Treatments:

Solid color blocks occupying 40-60% of slide
Gradient fills (vertical or diagonal only)
Split backgrounds (two colors, diagonal or vertical)
Edge-to-edge color bands
Negative space as a design element

Layout Tips

When creating slides with charts or tables:

Two-column layout (PREFERRED): Use a header spanning the full width, then two columns below - text/bullets in one column and the featured content in the other. This provides better balance and makes charts/tables more readable. Use flexbox with unequal column widths (e.g., 40%/60% split) to optimize space for each content type.
Full-slide layout: Let the featured content (chart/table) take up the entire slide for maximum impact and readability
NEVER vertically stack: Do not place charts/tables below text in a single column - this causes poor readability and layout issues

Workflow

MANDATORY - READ ENTIRE FILE: Read html2pptx.md completely from start to finish. NEVER set any range limits when reading this file. Read the full file content for detailed syntax, critical formatting rules, and best practices before proceeding with presentation creation.
Create an HTML file for each slide with proper dimensions (e.g., 720pt × 405pt for 16:9)
- Use <p>, <h1>-<h6>, <ul>, <ol> for all text content
- Use class="placeholder" for areas where charts/tables will be added (render with gray background for visibility)
- CRITICAL: Rasterize gradients and icons as PNG images FIRST using Sharp, then reference in HTML
- LAYOUT: For slides with charts/tables/images, use either full-slide layout or two-column layout for better readability
Create and run a JavaScript file using the html2pptx.js library to convert HTML slides to PowerPoint and save the presentation
- Use the html2pptx() function to process each HTML file
- Add charts and tables to placeholder areas using PptxGenJS API
- Save the presentation using pptx.writeFile()
Visual validation: Generate thumbnails and inspect for layout issues
- Create thumbnail grid: uv run scripts/thumbnail.py output.pptx workspace/thumbnails --cols 4
- Read and carefully examine the thumbnail image for:
  - Text cutoff: Text being cut off by header bars, shapes, or slide edges
  - Text overlap: Text overlapping with other text or shapes
  - Positioning issues: Content too close to slide boundaries or other elements
  - Contrast issues: Insufficient contrast between text and backgrounds
- If issues found, adjust HTML margins/spacing/colors and regenerate the presentation
- Repeat until all slides are visually correct

Editing an existing PowerPoint presentation

When edit slides in an existing PowerPoint presentation, you need to work with the raw Office Open XML (OOXML) format. This involves unpacking the .pptx file, editing the XML content, and repacking it.

Workflow

MANDATORY - READ ENTIRE FILE: Read ooxml.md (~425 lines) completely from start to finish. NEVER set any range limits when reading this file. Read the full file content for detailed guidance on OOXML structure and editing workflows before any presentation editing.
Unpack the presentation: uv run ooxml/scripts/unpack.py <office_file> <output_dir>
Edit the XML files (primarily ppt/slides/slide{N}.xml and related files)
CRITICAL: Validate immediately after each edit and fix any validation errors before proceeding: uv run ooxml/scripts/validate.py <dir> --original <file>
Pack the final presentation: `uv run ooxml/scripts/
