Pptx Generator
This handles programmatic PowerPoint generation in two modes: template-based (where you replace placeholders like {{TITLE}} in branded decks or cherry-pick slides from a library) and from-scratch JSON specs. The template analyzer is smart, it extracts an inventory of replaceable text so you know what you're working with. Runs on Deno with read/write permissions. Genuinely useful if you're generating quarterly reports, customizing pitch decks for different clients, or automating presentation workflows where maintaining corporate branding matters. Won't handle complex animations and only works with modern PPTX format, not legacy PPT files. The slide library feature for combining approved templates is the standout here.
