Creating Presentations
This is a full-featured PowerPoint manipulation toolkit that goes way beyond basic slide generation. It handles three distinct workflows: creating presentations from scratch using html2pptx (HTML to slides conversion), editing existing decks via direct OOXML XML manipulation, and working with templates through a structured extract and replace pipeline. The iron rules are sensible: web-safe fonts only, mandatory visual validation via thumbnail grids, and explicit color palette choices stated before code. You'll need a hefty dependency stack (LibreOffice, Playwright, PptxGenJS), but in return you get proper chart placeholders, layout swapping, and the ability to surgically edit presentation internals without corrupting the file structure. Best for programmatic slide deck generation or bulk template processing, not quick one-offs.
