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 |
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 |
scripts/office/soffice.py --headless --convert-to pdf deck.pptx | LibreOffice wrapper — bare soffice hangs in this sandbox |
pptxgenjs is preinstalled — do not run npm install first; write the script and require('pptxgenjs') directly. Only if that require fails: npm install pptxgenjs. The model knows the API; these are the footguns:
pres.layout before adding slides. The default canvas is LAYOUT_16x9 = 10" × 5.625", not 13.3" wide. Coordinates past the edge are written, not clamped — the shape just isn't on the slide. (LAYOUT_WIDE is 13.3" × 7.5".)#, never 8 digits. color: "FF0000". Both "#FF0000" and alpha baked into the hex ("00000020") corrupt the file. For translucency: transparency: 0-100 on fills and images, opacity: 0.0-1.0 on shadows — each is silently ignored on the other.shadow/options object across two add* calls — build a fresh object each time.offset must be ≥ 0 — a negative offset corrupts the file. To cast a shadow upward, use angle: 270 with a positive offset.letterSpacing is silently ignored — the real option is charSpacing.bullet: true on each item, never a literal • (renders double bullets). Set breakLine: true on every array item except the last. Space bulleted paragraphs with paraSpaceAfter, not lineSpacing (huge gaps).new pptxgen() per output file — never reuse an instance.rectRadius only works on ROUNDED_RECTANGLE, not RECTANGLE.margin: 0 whenever text must align with a shape, line, or icon at the same x.slide.addNotes("...") (plain text, once per slide), never in a text box on the slide.addChart() for everything PowerPoint can chart (pass an array of {type, data, options} for combos). For PowerPoint-native features the library doesn't expose (trendlines, error bars), compute the extra series yourself or post-process the generated OOXML — do not fall back to a rendered image. Only chart types PowerPoint has no native form for (Sankey, network, chord) go in as images.Pick layouts first: python scripts/thumbnail.py template.pptx template-thumbs writes a labeled grid of every slide and prints the file(s) it created — template-thumbs.jpg, split into template-thumbs-N.jpg past 12 slides. Always pass that second argument, named after the deck. It defaults to thumbnails, so two decks thumbnailed in one directory silently overwrite each other's grids — the first deck's are simply gone (template analysis only — visual QA needs the full-resolution renders from Converting to Images; it only accepts .pptx, so copy a .potx to a .pptx name first). Use it with markitdown to map each content section onto a template slide, and vary the layouts — don't put every section on the same title-and-bullets slide.
python3 -c "import sys,zipfile; zipfile.ZipFile(sys.argv[1]).extractall('unpacked')" deck.pptx
python scripts/add_slide.py unpacked/ slide2.xml --after slide2.xml # duplicate a slide (or slideLayoutN.xml); prints the new slide's path
# reorder / delete slides = edit <p:sldIdLst> in ppt/presentation.xml
python scripts/clean.py unpacked/ # after deletions: removes orphaned slides, media, rels
# edit slide content in ppt/slides/slideN.xml
(cd unpacked && rm -f ../out.pptx && zip -Xr ../out.pptx .) # zip from INSIDE the dir; rm first or deleted parts survive
python scripts/office/validate.py out.pptx --original deck.pptx
add_slide.py copies a slide file verbatim, so duplicating after you edit clones the edited content; and clean.py deletes any slide missing from <p:sldIdLst>, including one you just wrote.add_slide.py does every registration a new slide needs and reports what it made (Created ppt/slides/slide17.xml from slide2.xml). It also works directly on a file: add_slide.py deck.pptx slide2.xml -o out.pptx — pass -o, or it rewrites the input deck in place. A duplicated slide still references its source's chart/SmartArt/embedded-object parts rather than cloning them, so editing one slide's chart changes the other's.python-pptx, three things it won't do: duplicate a slide (its only entry point is add_slide(layout)), preserve formatting through text_frame.text = "..." (that collapses the paragraph to a single unstyled run — assign run.text instead), or read the SVG/EMF most template art uses (add_picture raises UnidentifiedImageError)..ppt must be converted first: python scripts/office/soffice.py --headless --convert-to pptx file.ppt. .potx templates unpack and pack identically — keep the .potx extension on the output.When filling in a template:
defusedxml.minidom — round-tripping OOXML through xml.etree.ElementTree rewrites namespace prefixes and corrupts the deck.<a:p> per list item — never concatenate items into a single paragraph. Copy the sibling <a:pPr> to preserve spacing, and put b="1" on the <a:rPr> of titles, section headers, and inline labels (Status:, Owner:).<a:buChar>, <a:buAutoNum> (numbered), or <a:buNone> to override — never a literal • in the text.xml:space="preserve" on its <a:t>.Don't create boring slides. Plain bullets on a white background won't impress anyone. Consider ideas from this list for each slide.

# 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 |
| `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 |
| `scripts/office/soffice.py --headless --convert-to pdf deck.pptx` | LibreOffice wrapper — bare `soffice` hangs in this sandbox |
## Creating with pptxgenjs — gotchas
`pptxgenjs` is preinstalled — do not run `npm install` first; write the script and `require('pptxgenjs')` directly. Only if that require fails: `npm install pptxgenjs`. The model knows the API; these are the footguns:
- **Set `pres.layout` before adding slides.** The default canvas is `LAYOUT_16x9` = **10" × 5.625"**, not 13.3" wide. Coordinates past the edge are written, not clamped — the shape just isn't on the slide. (`LAYOUT_WIDE` is 13.3" × 7.5".)
- **Hex colors: never `#`, never 8 digits.** `color: "FF0000"`. Both `"#FF0000"` and alpha baked into the hex (`"00000020"`) **corrupt the file**. For translucency: `transparency: 0-100` on fills and images, `opacity: 0.0-1.0` on shadows — each is silently ignored on the other.
- **pptxgenjs mutates option objects in place** (converts values to EMU on first use). Never share one `shadow`/options object across two `add*` calls — build a fresh object each time.
- **Shadow `offset` must be ≥ 0** — a negative offset corrupts the file. To cast a shadow upward, use `angle: 270` with a positive offset.
- **`letterSpacing` is silently ignored** — the real option is `charSpacing`.
- **Lists:** `bullet: true` on each item, never a literal `•` (renders double bullets). Set `breakLine: true` on every array item except the last. Space bulleted paragraphs with `paraSpaceAfter`, not `lineSpacing` (huge gaps).
- **One `new pptxgen()` per output file** — never reuse an instance.
- **`rectRadius` only works on `ROUNDED_RECTANGLE`**, not `RECTANGLE`.
- **Gradient fills aren't supported** — use a gradient image as the background instead.
- **Text boxes have built-in internal padding** — set `margin: 0` whenever text must align with a shape, line, or icon at the same x.
- **Speaker notes go in `slide.addNotes("...")`** (plain text, once per slide), never in a text box on the slide.
- **Keep charts native.** Use `addChart()` for everything PowerPoint can chart (pass an array of `{type, data, options}` for combos). For PowerPoint-native features the library doesn't expose (trendlines, error bars), compute the extra series yourself or post-process the generated OOXML — do not fall back to a rendered image. Only chart types PowerPoint has no native form for (Sankey, network, chord) go in as images.
- **Default charts render bare** — no title, no data labels, dated palette. Set `showTitle` + `title`, `showValue: true` + `dataLabelPosition`, `chartColors: [...]` from your palette, and quiet the frame (`catAxisLabelColor`/`valAxisLabelColor`, `valGridLine: { color, size }`, `catGridLine: { style: "none" }`, `showLegend: false` for a single series).
- **On a stacked bar or column chart, `dataLabelPosition` must be `ctr`, `inEnd`, or `inBase`.** `outEnd` **corrupts the file**.
- **A combo series using `secondaryValAxis`/`secondaryCatAxis` needs both `valAxes` and `catAxes` on the chart options, two entries each.** Without them pptxgenjs writes axis *ids* it never declares, and PowerPoint **discards that chart** and reports the file as corrupt. Supplying only `valAxes` is not enough.
- **After `writeFile()`, run `python scripts/office/validate.py deck.pptx`.** It reports the two chart faults above and the slide-XML defects PowerPoint refuses, and names the fix for each. Fix them in your generator, not by hand-editing the packed XML.
- **Never reorder the children of `<p:presentation>`.** pptxgenjs writes `<p:notesMasterIdLst>` right after `<p:sldIdLst>` and points both masters at one theme part. PowerPoint reads that happily — move the element and the same deck becomes unopenable.
- **Icons:** render `react-icons` to SVG (`ReactDOMServer.renderToStaticMarkup`), rasterize with `sharp` at ≥256px, and insert via `addImage({ data: "image/png;base64," + buf.toString("base64") })` — the `image/png;base64,` prefix is required (`react-icons`, `react`, `react-dom`, and `sharp` are preinstalled — `npm install react-icons react react-dom sharp` only if a require fails).
## Editing existing decks and templates
Pick layouts first: `python scripts/thumbnail.py template.pptx template-thumbs` writes a labeled grid of every slide and prints the file(s) it created — `template-thumbs.jpg`, split into `template-thumbs-N.jpg` past 12 slides. **Always pass that second argument, named after the deck.** It defaults to `thumbnails`, so two decks thumbnailed in one directory silently overwrite each other's grids — the first deck's are simply gone (template analysis only — visual QA needs the full-resolution renders from [Converting to Images](#converting-to-images); it only accepts `.pptx`, so copy a `.potx` to a `.pptx` name first). Use it with `markitdown` to map each content section onto a template slide, and vary the layouts — don't put every section on the same title-and-bullets slide.
```bash
python3 -c "import sys,zipfile; zipfile.ZipFile(sys.argv[1]).extractall('unpacked')" deck.pptx
python scripts/add_slide.py unpacked/ slide2.xml --after slide2.xml # duplicate a slide (or slideLayoutN.xml); prints the new slide's path
# reorder / delete slides = edit <p:sldIdLst> in ppt/presentation.xml
python scripts/clean.py unpacked/ # after deletions: removes orphaned slides, media, rels
# edit slide content in ppt/slides/slideN.xml
(cd unpacked && rm -f ../out.pptx && zip -Xr ../out.pptx .) # zip from INSIDE the dir; rm first or deleted parts survive
python scripts/office/validate.py out.pptx --original deck.pptx
```
- **Do all structural work — add, delete, reorder — before editing any slide's content.** `add_slide.py` copies a slide file verbatim, so duplicating after you edit clones the edited content; and `clean.py` deletes any slide missing from `<p:sldIdLst>`, including one you just wrote.
- **Never copy a slide file by hand** — `add_slide.py` does every registration a new slide needs and reports what it made (`Created ppt/slides/slide17.xml from slide2.xml`). It also works directly on a file: `add_slide.py deck.pptx slide2.xml -o out.pptx` — **pass `-o`, or it rewrites the input deck in place.** A duplicated slide still *references* its source's chart/SmartArt/embedded-object parts rather than cloning them, so editing one slide's chart changes the other's.
- **If you use `python-pptx`**, three things it won't do: duplicate a slide (its only entry point is `add_slide(layout)`), preserve formatting through `text_frame.text = "..."` (that collapses the paragraph to a single unstyled run — assign `run.text` instead), or read the SVG/EMF most template art uses (`add_picture` raises `UnidentifiedImageError`).
- Legacy `.ppt` must be converted first: `python scripts/office/soffice.py --headless --convert-to pptx file.ppt`. `.potx` templates unpack and pack identically — keep the `.potx` extension on the output.
- To reuse a template icon or image, duplicate a slide or layout that already contains it.
When filling in a template:
- If you script an XML transform, parse with `defusedxml.minidom` — round-tripping OOXML through `xml.etree.ElementTree` rewrites namespace prefixes and corrupts the deck.
- **Template slots ≠ source items.** If the template shows 4 team members and you have 3, delete the 4th member's entire group (image + text boxes), not just its text — then check for orphaned visuals in QA.
- One `<a:p>` per list item — never concatenate items into a single paragraph. Copy the sibling `<a:pPr>` to preserve spacing, and put `b="1"` on the `<a:rPr>` of titles, section headers, and inline labels (`Status:`, `Owner:`).
- Let bullets inherit from the layout; only add `<a:buChar>`, `<a:buAutoNum>` (numbered), or `<a:buNone>` to override — never a literal `•` in the text.
- Text with leading or trailing spaces needs `xml:space="preserve"` on its `<a:t>`.
## Design Ideas
**Don't create boring slides.** Plain bullets on a white background won't impress anyone. Consider ideas from this list for each slide.
### Before Starting
- **Pick a bold, content-informed color palette**: The palette should feel designed for THIS topic. If swapping your colors into a completely different presentation would still "work," you haven't made specific enough choices.
- **Dominance over equality**: One color should dominate (60-70% visual weight), with 1-2 supporting tones and one sharp accent. Never give all colors equal weight.
- **Dark/light contrast**: Dark backgrounds for title + conclusion slides, light for content ("sandwich" structure). Or commit to dark throughout for a premium feel.
- **Commit to a visual motif**: Pick ONE distinctive element and repeat it — rounded image frames, icons in colored circles. Carry it across every slide. **Do not use a color bar or accent stripe as your motif** (see Avoid list).
### Color Palettes
Choose colors that match your topic — don't default to generic blue. Use these palettes as inspiration:
| Theme | Primary | Secondary | Accent |
|-------|---------|-----------|--------|
| **Midnight Executive** | `1E2761` (navy) | `CADCFC` (ice blue) | `FFFFFF` (white) |
| **Forest & Moss** | `2C5F2D` (forest) | `97BC62` (moss) | `F5F5F5` (cream) |
| **Coral Energy** | `F96167` (coral) | `F9E795` (gold) | `2F3C7E` (navy) |
| **Warm Terracotta** | `B85042` (terracotta) | `E7E8D1` (sand) | `A7BEAE` (sage) |
| **Ocean Gradient** | `065A82` (deep blue) | `1C7293` (teal) | `21295C` (midnight) |
| **Charcoal Minimal** | `36454F` (charcoal) | `F2F2F2` (off-white) | `212121` (black) |

showTitle + title, showValue: true + dataLabelPosition, chartColors: [...] from your palette, and quiet the frame (catAxisLabelColor/valAxisLabelColor, valGridLine: { color, size }, catGridLine: { style: "none" }, showLegend: false for a single series).dataLabelPosition must be ctr, inEnd, or inBase. outEnd corrupts the file.secondaryValAxis/secondaryCatAxis needs both valAxes and catAxes on the chart options, two entries each. Without them pptxgenjs writes axis ids it never declares, and PowerPoint discards that chart and reports the file as corrupt. Supplying only valAxes is not enough.writeFile(), run python scripts/office/validate.py deck.pptx. It reports the two chart faults above and the slide-XML defects PowerPoint refuses, and names the fix for each. Fix them in your generator, not by hand-editing the packed XML.<p:presentation>. pptxgenjs writes <p:notesMasterIdLst> right after <p:sldIdLst> and points both masters at one theme part. PowerPoint reads that happily — move the element and the same deck becomes unopenable.react-icons to SVG (ReactDOMServer.renderToStaticMarkup), rasterize with sharp at ≥256px, and insert via addImage({ data: "image/png;base64," + buf.toString("base64") }) — the image/png;base64, prefix is required (react-icons, react, react-dom, and sharp are preinstalled — npm install react-icons react react-dom sharp only if a require fails).Copies are not installs. Installation counts require a reported successful installation; they are not a blanket quality guarantee.
