What problem does it solve?

This Skill removes the guesswork of manually editing complex PowerPoint (.pptx) files by enabling reliable creation, structured text replacement, and layout-aware analysis.

Core Features & Use Cases

  • Create and build decks: Generate new presentations from scratch by converting HTML slide layouts into .pptx with controlled styling and positioning.
  • Edit existing decks: Unpack a .pptx into Office Open XML (OOXML), modify slide XML safely, validate, then repack.
  • Analyze & validate content: Extract a full text inventory (including bullet formatting), estimate text overflow risk, and help produce thumbnail grids for visual QA.
  • Workflow examples:
    • Update a slide deck’s titles, bullets, and speaker notes using an automatically generated text inventory + replacement JSON.
    • Create a brand-consistent slide deck by defining CSS variables once, then converting multiple HTML slides into a single .pptx.

Quick Start

Use the pptx skill to convert the attached presentation draft into a corrected slide deck by first extracting its text inventory and then applying targeted replacements.
