PPTX creation, editing, and analysis
A .pptx is a ZIP archive of XML files. Choose your approach by task:
| Task | Approach |
|---|---|
| Create a new deck | Write a pptxgenjs script — see gotchas below |
| Edit an existing deck, or build from a template | unzip → edit ppt/slides/slideN.xml → zip |
| Read content | markitdown deck.pptx (one block per slide under <!-- Slide number: N --> markers); visual grid: python scripts/thumbnail.py deck.pptx |
Scripts
Paths are relative to this skill's directory. Everything else is plain Python, node, or shell.
| Script | What it does |
|---|---|
scripts/thumbnail.py deck.pptx [prefix] | Labeled grid of every slide, for picking template layouts. .pptx only. Pass prefix — it defaults to thumbnails, which overwrites the grids of any other deck done in the same directory |
scripts/add_slide.py unpacked/ slide2.xml [--after slideN.xml] | Duplicate a slide (or a slideLayoutN.xml) with all the package bookkeeping. Also takes a .pptx directly with -o out.pptx |
scripts/clean.py unpacked/ | Delete slides, media, and rels no longer referenced. Run after <p:sldIdLst> is final |
