Core Operations
Create Presentation (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_layout = prs.slide_layouts[0]
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"
bullet_layout = prs.slide_layouts[1]
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
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)
import pptxgen from 'pptxgenjs';
const pptx = new pptxgen();
pptx.author = 'Product Team';
pptx.title = 'Q4 Business Review';
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'
});
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 });
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)
from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE
chart_layout = prs.slide_layouts[5]
slide = prs.slides.add_slide(chart_layout)
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))
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
slide = prs.slides.add_slide(prs.slide_layouts[5])
slide.shapes.add_picture('logo.png', Inches(0.5), Inches(0.5), width=Inches(2))
rows, cols = 4, 3
table = slide.shapes.add_table(rows, cols, Inches(1), Inches(2), Inches(8), Inches(3)).table
table.cell(0, 0).text = 'Product'
table.cell(0, 1).text = 'Sales'
table.cell(0, 2).text = 'Growth'
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
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 |
