  • Edit & Template Workflows: Unpack a PPTX, map content to layout slides, edit slide XML reliably, clean orphaned resources, and repack into a valid presentation.
  • Create from Scratch: Use JavaScript/Node flows (pptxgenjs) guidance to generate new decks programmatically when no template exists.
  • Visual QA & Conversion: Produce thumbnails and convert slides to images for visual inspection and QA using headless office tools.
  • Use Case: Convert a design template into a polished pitch deck by mapping content into varied slide layouts, running visual QA, fixing overflows, and repacking a validated .pptx.
