PPTX Presentation Creation & Editing

Lets Claude build, edit, and analyze PowerPoint (.pptx) decks via HTML-to-PPTX conversion, raw OOXML editing, or existing corporate templates.

Docs & OfficeIntermediate★ 169⑂ 11AI score 10/10Last updated: Sep 13, 2026

What it does

  • Create decks from scratch: author each slide as HTML (720pt × 405pt for 16:9) and convert it with the bundled html2pptx.js library for pixel-accurate positioning. Ships with 18 curated color palettes, web-safe font rules, and layout guidance for charts and tables.
  • Edit existing files: unpack the .pptx ZIP, edit the underlying OOXML (slides, speaker notes, comments, layouts, themes), validate with validate.py, then repack.
  • Work from a template: generate thumbnail grids, build a slide inventory, duplicate/reorder slides with rearrange.py, then swap text through inventory.py and replace.py while preserving bullets, alignment, fonts, and colors.
  • Visual QA loop: render slides to PDF/JPEG via LibreOffice + poppler and inspect for text cutoff, overlap, and contrast problems before delivering.

Who it's for

  • Consultants, analysts, and marketers producing frequent reports and pitch decks
  • Teams that must fill in a fixed corporate PowerPoint template again and again
  • Developers automating bulk text replacement or QA across large slide sets

Examples

  1. "Build a 12-slide Q3 results deck in 16:9" → picks a topic-appropriate palette, writes HTML slides, converts to PPTX, then reviews the thumbnail grid for layout issues.
  2. "Use our 73-slide brand template and produce an 8-slide proposal" → inventories the template, maps outline sections to slide indices, rearranges, and replaces placeholder text.
  3. "Rewrite the speaker notes on slide 5 in English" → unpacks the file, edits notesSlide5.xml directly, validates, and repacks.
