PowerPoint Generator

Generate professional PPTX files using python-pptx.

Rules (Mandatory)

1. Every presentation MUST have: title slide, agenda/outline, content slides, summary/next-steps slide
2. No wall-of-text slides — max 6 bullet points per slide, max 8 words per bullet
3. Every data claim gets a chart or table — never present numbers as plain text
4. Speaker notes on every slide — full context the presenter needs
5. Consistent theme — colors, fonts, and spacing uniform throughout
6. File output — always save to a concrete path and confirm it exists

Slide Types

Type	When	Layout
Title	Opening	Large title + subtitle + date
Section	Chapter break	Section title + brief description
Content	Key points	Title + bullets (max 6)
Two-Column	Comparison	Title + left/right content
Chart	Data	Title + chart (bar/line/pie) + caption
Table	Structured data	Title + table + footnote
Image	Visual	Title + placeholder for image path
Quote	Testimonial	Large quote + attribution
Summary	Closing	Key takeaways + next steps

python-pptx Patterns

from pptx import Presentation
from pptx.util import Inches, Pt, Emu
from pptx.dml.color import RGBColor
from pptx.enum.text import PP_ALIGN, MSO_ANCHOR
from pptx.enum.chart import XL_CHART_TYPE

prs = Presentation()
prs.slide_width = Inches(13.333)   # 16:9 widescreen
prs.slide_height = Inches(7.5)

# Add slide
slide_layout = prs.slide_layouts[1]  # Title + Content
slide = prs.slides.add_slide(slide_layout)
slide.shapes.title.text = "Slide Title"

# Add chart
chart_data = CategoryChartData()
chart_data.categories = ['Q1', 'Q2', 'Q3', 'Q4']
chart_data.add_series('Revenue', (1.2, 1.5, 1.8, 2.3))
slide.shapes.add_chart(XL_CHART_TYPE.COLUMN_CLUSTERED, x, y, cx, cy, chart_data)

# Speaker notes
slide.notes_slide.notes_text_frame.text = "Full context here"

prs.save("output.pptx")

Workflow

1. Structure — outline slides with types and key content
2. Theme — set colors, fonts, slide dimensions (default 16:9)
3. Build — create slides programmatically
4. Charts/Tables — add data visualizations
5. Notes — add speaker notes to every slide
6. Save — write to file, verify it exists
