PPT Generator
This skill enables comprehensive PowerPoint presentation management through multiple approaches:
- Python-based Creation: Use python-pptx library for programmatic generation with professional styling
- Direct OOXML Editing: Unpack, modify XML content, and repack PPTX files for advanced control
- Template-based Workflow: Leverage existing templates with content replacement
PPTX files are ZIP archives containing XML files and resources. This architecture enables both high-level creation and low-level manipulation.

Implementation
The skill uses Python with the python-pptx library to process PowerPoint files. Run the processing script:
python scripts/create_ppt.py [options]
Script Usage
The script supports multiple ways to create presentations:
1. Simple command-line creation:
python scripts/create_ppt.py --output presentation.pptx --title "My Presentation"
2. JSON-based content definition:
python scripts/create_ppt.py --output presentation.pptx --json slides.json
3. Enhanced command-line creation with color scheme:
python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --color-scheme feedmob
4. Presentation with background image:
python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --background-image "bg.jpg"
5. Presentation with automatic backgrounds and logos (NEW):
python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --color-scheme feedmob
6. Disable automatic backgrounds or logos:
python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --no-auto-backgrounds
python scripts/create_ppt.py --output presentation.pptx --title "My Presentation" --no-auto-logos
The script will:
- Create a new PowerPoint presentation with professional styling
- Apply FeedMob or Binance color scheme by default (or selected alternative theme)
- NEW: Automatically select background images based on slide content (enabled by default)
- NEW: Automatically add logos to slides without backgrounds (enabled by default)
- Add slides with enhanced typography and layout
- Insert text and images with proper formatting
- Save the final .pptx file
- Handle errors gracefully with clear messages

Requirements
- Python 3.6 or higher
- python-pptx library (>=0.6.21)
- Image files must exist at specified paths (for image insertion)
Output
- A .pptx file saved to the specified location
- Standard PowerPoint format compatible with Microsoft PowerPoint, LibreOffice, and Google Slides
- Preserves all formatting and layout settings
OOXML Direct Manipulation
For advanced editing beyond python-pptx capabilities, directly manipulate the OOXML structure:
Unpacking PPTX
# PPTX files are ZIP archives
unzip presentation.pptx -d unpacked/
Key OOXML Files
ppt/presentation.xml- Slide order and IDsppt/slides/slide*.xml- Individual slide contentppt/slideLayouts/- Layout templatesppt/media/- Embedded images[Content_Types].xml- File type declarationsppt/_rels/presentation.xml.rels- Slide relationships
Common Operations
Rearrange Slides: Modify <p:sldId> sequence in presentation.xml
Replace Text: Edit text within <a:t> tags in slide XML files
Duplicate Slides: Copy slide XML and update IDs in relationships
Delete Slides: Remove references from presentation.xml, relationships, and Content_Types
Repacking PPTX
cd unpacked/
zip -r ../modified.pptx * -x "*.DS_Store"
Critical: Validate OOXML structure before repacking. Incorrect XML causes corrupted files.
Design Principles
Follow these principles for professional presentations:
Content-Informed Design
- Design should serve content, not overshadow it
- Use strong visual hierarchy
- Maintain readable contrast (WCAG AA minimum)
- Use web-safe fonts (Arial, Helvetica, Times New Roman, Georgia)
Typography Standards
- Title: ≥28pt for readability
- Body: ≥18pt minimum
- Consistent font family throughout
- Limited font variations (2-3 weights max)
Color Guidelines
- 60-30-10 Rule: 60% primary, 30% secondary, 10% accent
- Maximum 4 colors per chart
- Consistent color mapping across visualizations
- Test contrast ratios for accessibility
Layout Optimization
- 6x6 Rule: Max 6 lines per slide, 6 words per line
- 20% Margins: Minimum white space for readability
- Grid Alignment: Use 12x8 grid for element positioning
- Visual Balance: Distribute weight evenly across slide
Recommended Color Palettes
Choose palettes that match presentation tone:
Professional Business: Navy (#1a3a5c), Gray (#6b7280), Blue (#3b82f6) Technology: Teal (#00B5AD), Purple (#8b5cf6), Cyan (#06b6d4) Corporate: Charcoal (#374151), Gold (#f59e0b), White (#ffffff) Modern: Black (#000000), Coral (#EE6969), Mint (#10b981)
Best Practices
Planning
- Define Structure First: Outline slide flow before detailed content
- Content-Informed Design: Let content guide design choices
- Consistent Theme: Maintain visual consistency throughout
Implementation
- Use Appropriate Tools: python-pptx for creation, OOXML for complex edits
- Validate Early: Check output after each major change
- Keep Text Concise: Follow 6x6 rule for readability
- Optimize Assets: Compress images before insertion
Quality Assurance
- Test Compatibility: Open in PowerPoint, LibreOffice, Google Slides
- Check Accessibility: Verify contrast ratios and font sizes
- Validate OOXML: Ensure no corrupted relationships or missing files
- Review on Device: Test on actual presentation display

Python Environment:
- Python 3.6+
- python-pptx >= 0.6.21
Optional Tools:
- markitdown (text extraction)
