Overview

This skill generates PowerPoint (.pptx) presentations programmatically, including slides, charts, images, tables, and design templates. It streamlines building consistent slide decks from code, suitable for reports, dashboards, and automated exports. Versioned tooling provides a predictable, reusable workflow for presentation generation.

How this skill works

The skill constructs Presentation objects, adds slide layouts (title, content, blank), and populates placeholders with text, paragraphs, and hierarchical bullet levels. It creates common chart types (bar, line, pie), inserts images at specified positions and sizes, and builds tables with rows and columns. Templates and formatting options let you apply consistent styles and export a final .pptx file for distribution.

When to use it

Automating report or dashboard exports on a schedule
Generating slide decks from data pipelines or APIs
Batch-creating customized presentations for clients or teams
Programmatic creation of charts and tables for reproducible slides
Embedding images or charts produced by other tools into slides

Best practices

Design a base template with master slides to enforce branding and reduce per-slide formatting
Build slides from structured data models to keep content predictable and testable
Generate charts as image assets when advanced styling is needed, then insert images for consistency
Limit complex layout edits at runtime; prefer placeholder-based content insertion
Save and validate .pptx output in a CI step to catch formatting regressions early

Example use cases

Create a weekly KPI presentation by pulling metrics, generating charts, and exporting a deck automatically
Produce client proposals with templated title and content slides populated from a CRM
Convert notebook analysis outputs into a slide deck with images of plots and summary tables
Batch-generate individualized training materials by merging user data into template slides
Assemble investor update slides with programmatically generated financial charts

FAQ

Which chart types are supported?

Common chart types are supported, including bar, line, and pie charts; you can also insert externally generated chart images.

Can I apply a corporate template or master slide?

Yes. Use a base template with master slides and apply it when creating the Presentation to keep branding and layout consistent.
