SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires defusedxml, Pillow, lxml, and includes scripts (resource) components.

What problem does it solve?

Working with PowerPoint files often requires switching between many brittle tools: extracting text and images, adapting templates, editing slide XML, validating relationships, and converting slides to images. This Skill consolidates those capabilities into a single, repeatable workflow so teams can automate building, editing, QA, and packaging of .pptx decks without manual ZIP or XML hacking.

Core Features & Use Cases

  • Read and extract text, speaker notes, and assets from .pptx files for summaries, repurposing, or translation.
  • Generate visual overviews and thumbnail grids to inspect templates and layouts quickly.
  • Unpack and repack PPTX with safe structural edits, including scripts to add or duplicate slides, clean orphaned resources, and validate against OOXML schemas.
  • Create presentations from scratch using pptxgenjs patterns and templates, including image and chart handling.
  • Validate and auto-repair common file issues (broken relationships, missing content types, id constraints) to prevent corrupted output.
  • Use cases: converting templates to finalized decks, bulk template adaptation for slide mappings, QA and visual review using exported images, and producing sanitized, validated deliverables for publishing.

Quick Start

Run the pptx workflows on presentation.pptx to extract text and thumbnails, validate and clean the unpacked XML, then repack a corrected output.pptx.
