# 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 `` 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 | | `scripts/office/validate.py deck.pptx [--original src.pptx]` | Schema, relationship, content-type, chart and slide checks; each failure names its fix. Pass `--original` for any template-derived deck — it baselines the schema checks against the template, so the template's own XSD errors don't read as yours |
