## Quick Reference

| Task | Tool/Library | Language | When to Use |
|------|--------------|----------|-------------|
| Create PPTX | python-pptx | Python | Presentations, slide decks |
| Create PPTX | pptxgenjs | Node.js | Server-side generation |
| Templates | python-pptx | Python | Master slides, themes |
| Charts | python-pptx | Python | Data visualizations |
| Extract content | python-pptx | Python | Parse existing decks |

## When to Use This Skill

Claude should invoke this skill when a user requests:

- Generate PowerPoint presentations from data
- Create slide decks with charts and images
- Automate report generation as slides
- Extract content from existing presentations
- Apply consistent branding/templates
- Generate speaker notes
- Create training or educational materials

## Core Operations

### Create Presentation (Python)

```python
from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.enum.text import PP_ALIGN
from pptx.dml.color import RgbColor

prs = Presentation()

# Title slide
title_layout = prs.slide_layouts[0]  # Title Slide layout
slide = prs.slides.add_slide(title_layout)
title = slide.shapes.title
subtitle = slide.placeholders[1]
title.text = "Q4 2025 Business Review"
subtitle.text = "Presented by Product Team"

# Content slide with bullets
bullet_layout = prs.slide_layouts[1]  # Title and Content
slide = prs.slides.add_slide(bullet_layout)
slide.shapes.title.text = "Key Highlights"
body = slide.placeholders[1]
tf = body.text_frame
tf.text = "Revenue grew 25% YoY"

p = tf.add_paragraph()
p.text = "Customer base expanded to 10,000+"
p.level = 0

p = tf.add_paragraph()
p.text = "New enterprise tier launched"
p.level = 1  # Indented bullet

# Add speaker notes
notes_slide = slide.notes_slide
notes_slide.notes_text_frame.text = "Emphasize the enterprise growth story here."

prs.save('presentation.pptx')
```

### Create Presentation (Node.js)

```typescript
import pptxgen from 'pptxgenjs';

const pptx = new pptxgen();
pptx.author = 'Product Team';
pptx.title = 'Q4 Business Review';

// Title slide
let slide = pptx.addSlide();
slide.addText('Q4 2025 Business Review', {
  x: 1, y: 2, w: '80%',
  fontSize: 36, bold: true, color: '363636',
  align: 'center'
});
slide.addText('Presented by Product Team', {
  x: 1, y: 3.5, w: '80%',
  fontSize: 18, color: '666666',
  align: 'center'
});

// Content slide with bullets
slide = pptx.addSlide();
slide.addText('Key Highlights', {
  x: 0.5, y: 0.5, w: '90%',
  fontSize: 28, bold: true
});
slide.addText([
  { text: 'Revenue grew 25% YoY', options: { bullet: true } },
  { text: 'Customer base expanded to 10,000+', options: { bullet: true } },
  { text: 'New enterprise tier launched', options: { bullet: true, indentLevel: 1 } },
], { x: 0.5, y: 1.5, w: '90%', fontSize: 18 });

// Add chart
slide = pptx.addSlide();
slide.addChart(pptx.ChartType.bar, [
  { name: 'Q1', labels: ['Sales'], values: [100] },
  { name: 'Q2', labels: ['Sales'], values: [150] },
  { name: 'Q3', labels: ['Sales'], values: [180] },
  { name: 'Q4', labels: ['Sales'], values: [225] },
], { x: 1, y: 1.5, w: 8, h: 4 });

await pptx.writeFile({ fileName: 'presentation.pptx' });
```

### Add Charts (Python)

```python
from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE

# Add slide with chart
chart_layout = prs.slide_layouts[5]  # Blank
slide = prs.slides.add_slide(chart_layout)

# Chart data
chart_data = CategoryChartData()
chart_data.categories = ['Q1', 'Q2', 'Q3', 'Q4']
chart_data.add_series('Revenue', (100, 150, 180, 225))
chart_data.add_series('Expenses', (80, 90, 100, 110))

# Add chart
x, y, cx, cy = Inches(1), Inches(1.5), Inches(8), Inches(5)
chart = slide.shapes.add_chart(
    XL_CHART_TYPE.COLUMN_CLUSTERED,
    x, y, cx, cy,
    chart_data
).chart

chart.has_legend = True
chart.legend.include_in_layout = False
```

### Add Images and Tables

```python
# Add image
slide = prs.slides.add_slide(prs.slide_layouts[5])
slide.shapes.add_picture('logo.png', Inches(0.5), Inches(0.5), width=Inches(2))

# Add table
rows, cols = 4, 3
table = slide.shapes.add_table(rows, cols, Inches(1), Inches(2), Inches(8), Inches(3)).table

# Set column headers
table.cell(0, 0).text = 'Product'
table.cell(0, 1).text = 'Sales'
table.cell(0, 2).text = 'Growth'

# Fill data
data = [
    ('Widget A', '$1.2M', '+25%'),
    ('Widget B', '$800K', '+15%'),
    ('Widget C', '$500K', '+40%'),
]
for row_idx, (product, sales, growth) in enumerate(data, 1):
    table.cell(row_idx, 0).text = product
    table.cell(row_idx, 1).text = sales
    table.cell(row_idx, 2).text = growth
```

### Extract Content

```python
from pptx import Presentation

prs = Presentation('existing.pptx')

for slide_num, slide in enumerate(prs.slides, 1):
    print(f"\n--- Slide {slide_num} ---")
    for shape in slide.shapes:
        if shape.has_text_frame:
            for paragraph in shape.text_frame.paragraphs:
                print(paragraph.text)
        if shape.has_table:
            table = shape.table
            for row in table.rows:
                row_text = [cell.text for cell in row.cells]
                print(row_text)
```

## Slide Layout Reference

| Layout Index | Name | Use Case |
|--------------|------|----------|
| 0 | Title Slide | Opening, section dividers |
| 1 | Title and Content | Standard bullet slides |
| 2 | Section Header | Section transitions |
| 3 | Two Content | Side-by-side comparison |
| 4 | Comparison | Pros/cons, before/after |
| 5 | Title Only | Custom content placement |
| 6 | Blank | Full creative control |
| 7 | Content with Caption | Image + description |
