Presentation Builder

This handles the full lifecycle of PowerPoint files through direct XML manipulation and HTML-to-PPTX conversion. You get two main paths: extract content using markitdown for quick text reads, or unpack the entire OOXML structure when you need to work with animations, speaker notes, or complex formatting. The creation workflow is opinionated in a good way. It pushes you to think about design choices before generating slides, includes 18 preset color palettes ranging from classic blues to retro rainbows, and enforces web-safe fonts with actual readability requirements. The layout guidance is detailed enough to be useful, covering everything from two-column chart layouts to geometric pattern options. If you're building presentation tooling or need programmatic deck generation with real design consideration, this gives you the scaffolding.
