pptx

Work with PowerPoint .pptx files using python-pptx (preinstalled). A .pptx is a ZIP of XML parts; python-pptx handles the structure so you rarely touch XML. Drop to raw OOXML only for the few things the library can't express (see Advanced).

Run complete Python source with code_execution in the current workspace dir where uploaded files land. Refer to the deck exactly as the Generated artifacts list names it. Use exec only for a genuinely shell-only command; never put this source in python -c or a heredoc.

Mental model

A presentation has slides; each slide is built from a layout; layouts live on slide masters. Layouts define placeholders (title, body, picture, etc.) by idx and type.
A slide holds shapes: placeholders, text boxes, pictures, tables, charts.
Shapes with text expose .text_frame → .paragraphs → .runs. A run is the unit that carries formatting (font, size, bold, color).
Units are EMU. Use the helpers: from pptx.util import Inches, Pt, Emu.

Read / extract

from pptx import Presentation

prs = Presentation("deck.pptx")
print(len(prs.slides), prs.slide_width, prs.slide_height)  # EMU dims

for i, slide in enumerate(prs.slides, 1):
    print(f"--- slide {i} (layout: {slide.slide_layout.name}) ---")
    for shape in slide.shapes:
        if shape.has_text_frame:
            print(shape.text_frame.text)  # \n-joined paragraphs
        elif shape.has_table:
            for row in shape.table.rows:
                print([c.text for c in row.cells])
    if slide.has_notes_slide:
        notes = slide.notes_slide.notes_text_frame.text
        if notes:
            print("NOTES:", notes)

Iterate slide.placeholders to see placeholder idx / placeholder_format.type. For a fast text-only dump, just collect shape.text_frame.text across slides.

Create from an outline

List the layouts first — indices vary by template. With the default template, layout 0 = Title, 1 = Title+Content, 5 = Title Only, 6 = Blank.

from pptx import Presentation
from pptx.util import Inches, Pt

prs = Presentation()  # or Presentation("template.pptx") to inherit a theme
for idx, lay in enumerate(prs.slide_layouts):
    print(idx, lay.name, [(p.placeholder_format.idx, p.name) for p in lay.placeholders])

# Title slide
s = prs.slides.add_slide(prs.slide_layouts[0])
s.shapes.title.text = "My Deck"
s.placeholders[1].text = "Subtitle"  # idx from the listing above

# Title + bullets
s = prs.slides.add_slide(prs.slide_layouts[1])
s.shapes.title.text = "Agenda"
tf = s.placeholders[1].text_frame
tf.text = "First point"  # first paragraph
for line, lvl in [("Second", 0), ("Sub-point", 1)]:
    p = tf.add_paragraph()
    p.text = line
    p.level = lvl

prs.save("out.pptx")

Always set text via placeholders/shapes — never hand-write bullet glyphs (•); indentation/bullets come from the layout via paragraph.level.

Add a free text box or picture on any slide:

tb = s.shapes.add_textbox(Inches(1), Inches(1), Inches(8), Inches(1))
r = tb.text_frame.paragraphs[0].add_run()
r.text = "Hi"
r.font.size = Pt(28)
r.font.bold = True
s.shapes.add_picture("logo.png", Inches(0.5), Inches(0.5), height=Inches(1))  # omit w to keep ratio

Edit existing

Edit at the run level to preserve a run's formatting; rewriting text_frame.text collapses to one run and drops inline formatting.

for slide in prs.slides:
    for shape in slide.shapes:
        if not shape.has_text_frame:
            continue
        for para in shape.text_frame.paragraphs:
            for run in para.runs:
                if "{{NAME}}" in run.text:
                    run.text = run.text.replace("{{NAME}}", "Frank")

To delete a shape/placeholder: sp = shape._element; sp.getparent().remove(sp). If the template has more slots than your data, remove the extra shapes entirely rather than leaving empty placeholders.

Replace an image in place (keep size/position)

python-pptx has no direct setter; swap the bytes of the related image part. Read the picture's r:embed rId off its <a:blip>, then overwrite the part's blob.

from pptx.oxml.ns import qn

for shape in slide.shapes:
    if shape.shape_type == 13:  # MSO_SHAPE_TYPE.PICTURE
        blip = shape._element.find(".//" + qn("a:blip"))
        rid = blip.get(qn("r:embed"))
        with open("new.png", "rb") as f:
            shape.part.related_part(rid)._blob = f.read()

Tables and charts

from pptx.util import Inches

tbl = s.shapes.add_table(
    rows=2, cols=2, left=Inches(1), top=Inches(1), width=Inches(6), height=Inches(2)
).table
tbl.cell(0, 0).text = "Header"

from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE

cd = CategoryChartData()
cd.categories = ["Q1", "Q2", "Q3"]
cd.add_series("Sales", (4.5, 5.5, 6.2))
s.shapes.add_chart(XL_CHART_TYPE.COLUMN_CLUSTERED, Inches(1), Inches(1), Inches(8), Inches(4.5), cd)

Design (only when the user wants a polished deck, not a data dump)

Pick a topic-specific palette and one accent; don't default to generic blue. One color should dominate. Dark title/closing slides, light content slides.
Vary layouts across slides (two-column, stat callout, quote, section divider) — repeating one bullet layout reads as low-effort. Give most slides a visual element (image/chart/shape), not just title + bullets.
Type scale: title 36-44pt, section headers 20-24pt, body 14-16pt. Bold headers and inline labels. Left-align body; center only titles. Keep >=0.5in margins.
Set text_frame.word_wrap = True and watch for overflow; long replacement text may spill. After rendering (see Export), inspect the images critically — assume there are overlap/overflow/contrast bugs and fix them before declaring done.

Export to PDF / images (optional, needs LibreOffice)

command -v soffice >/dev/null || { echo "soffice not available — cannot export"; exit 0; }
soffice --headless --convert-to pdf out.pptx
command -v pdftoppm >/dev/null && pdftoppm -jpeg -r 150 out.pdf slide && ls -1 "$PWD"/slide-*.jpg

Read the printed JPG paths with your image-view capability to verify visually. Re-run conversion after every edit — the PDF won't reflect a changed .pptx otherwise. If soffice (or pdftoppm) is absent, say so and skip export; do NOT pip-install.

.ppt → .pptx

Legacy .ppt is a different binary format — python-pptx cannot open it. Convert first if soffice exists, else tell the user it can't be processed:

command -v soffice >/dev/null && soffice --headless --convert-to pptx old.ppt || echo "need soffice for .ppt"

Advanced: raw OOXML (last resort)

Use only for things python-pptx can't do (e.g. exact-fidelity slide duplication, gradient fills, theme color edits, untyped XML elements). python-pptx already exposes each shape's XML via shape._element (lxml) — prefer surgical lxml edits there over a full unzip when you can. For part-level surgery, unzip → edit the XML part → re-zip with stdlib zipfile.

Package map: slide order in ppt/presentation.xml <p:sldIdLst>; slides in ppt/slides/slideN.xml with rels in ppt/slides/_rels/slideN.xml.rels; layouts/ masters under ppt/slideLayouts, ppt/slideMasters; media in ppt/media/; part types in [Content_Types].xml.

Critical invariants if you add/edit parts by hand — break one and PowerPoint reports the file as corrupt:

Every new part is declared in [Content_Types].xml (an <Override> for slides; a <Default> per media extension like png/jpeg).
Every cross-part link goes through a _rels/*.rels <Relationship>; r:id refs in XML must resolve. Adding a slide means: write the part + its .rels, add the content-type override, add a <Relationship> in presentation.xml.rels, and a <p:sldId> in <p:sldIdLst>.
IDs must be unique: <p:sldId> ids, and shape ids (<p:cNvPr id=...>) within a slide. sldLayoutId/sldMasterId are globally unique.
Whitespace: any <a:t> with leading/trailing spaces needs xml:space="preserve".
Parse/serialize with lxml or defusedxml; never naive string munging that mangles namespaces or pretty-prints into text nodes.

Minimal text edit by zip surgery (zip members can't be overwritten in place — rebuild the archive, swapping the one part):

import zipfile

target = "ppt/slides/slide1.xml"
with zipfile.ZipFile("in.pptx") as zin:
    xml = zin.read(target).decode().replace("Old title", "New title")
    with zipfile.ZipFile("out.pptx", "w", zipfile.ZIP_DEFLATED) as zout:
        for item in zin.namelist():
            zout.writestr(item, xml.encode() if item == target else zin.read(item))

Verify before done

Reopen the output with Presentation("out.pptx") and assert slide count / key text — a clean reopen catches most corruption. For decks meant to look good, also export and visually inspect (above). Check templates for leftover placeholder text (xxxx, lorem, [insert ...]) and fix before declaring done.

# pptx

Work with PowerPoint `.pptx` files using **python-pptx** (preinstalled). A `.pptx`
is a ZIP of XML parts; python-pptx handles the structure so you rarely touch XML.
Drop to raw OOXML only for the few things the library can't express (see Advanced).

Run complete Python source with `code_execution` in the current workspace dir
where uploaded files land. Refer to the deck exactly as the Generated artifacts
list names it. Use `exec` only for a genuinely shell-only command; never put
this source in `python -c` or a heredoc.

## Mental model
- A presentation has **slides**; each slide is built from a **layout**; layouts
  live on **slide masters**. Layouts define **placeholders** (title, body,
  picture, etc.) by `idx` and type.
- A slide holds **shapes**: placeholders, text boxes, pictures, tables, charts.
- Shapes with text expose `.text_frame` → `.paragraphs` → `.runs`. A run is the
  unit that carries formatting (font, size, bold, color).
- Units are EMU. Use the helpers: `from pptx.util import Inches, Pt, Emu`.

## Read / extract
```python
from pptx import Presentation

prs = Presentation("deck.pptx")
print(len(prs.slides), prs.slide_width, prs.slide_height)  # EMU dims

for i, slide in enumerate(prs.slides, 1):
    print(f"--- slide {i} (layout: {slide.slide_layout.name}) ---")
    for shape in slide.shapes:
        if shape.has_text_frame:
            print(shape.text_frame.text)  # \n-joined paragraphs
        elif shape.has_table:
            for row in shape.table.rows:
                print([c.text for c in row.cells])
    if slide.has_notes_slide:
        notes = slide.notes_slide.notes_text_frame.text
        if notes:
            print("NOTES:", notes)
```
Iterate `slide.placeholders` to see placeholder `idx` / `placeholder_format.type`.
For a fast text-only dump, just collect `shape.text_frame.text` across slides.

## Create from an outline
List the layouts first — indices vary by template. With the default template,
layout 0 = Title, 1 = Title+Content, 5 = Title Only, 6 = Blank.
```python
from pptx import Presentation
from pptx.util import Inches, Pt

prs = Presentation()  # or Presentation("template.pptx") to inherit a theme
for idx, lay in enumerate(prs.slide_layouts):
    print(idx, lay.name, [(p.placeholder_format.idx, p.name) for p in lay.placeholders])

# Title slide
s = prs.slides.add_slide(prs.slide_layouts[0])
s.shapes.title.text = "My Deck"
s.placeholders[1].text = "Subtitle"  # idx from the listing above

# Title + bullets
s = prs.slides.add_slide(prs.slide_layouts[1])
s.shapes.title.text = "Agenda"
tf = s.placeholders[1].text_frame
tf.text = "First point"  # first paragraph
for line, lvl in [("Second", 0), ("Sub-point", 1)]:
    p = tf.add_paragraph()
    p.text = line
    p.level = lvl

prs.save("out.pptx")
```
Always set text via placeholders/shapes — never hand-write bullet glyphs (`•`);
indentation/bullets come from the layout via `paragraph.level`.

Add a free text box or picture on any slide:
```python
tb = s.shapes.add_textbox(Inches(1), Inches(1), Inches(8), Inches(1))
r = tb.text_frame.paragraphs[0].add_run()
r.text = "Hi"
r.font.size = Pt(28)
r.font.bold = True
s.shapes.add_picture("logo.png", Inches(0.5), Inches(0.5), height=Inches(1))  # omit w to keep ratio
```

## Edit existing
Edit at the **run** level to preserve a run's formatting; rewriting
`text_frame.text` collapses to one run and drops inline formatting.
```python
for slide in prs.slides:
    for shape in slide.shapes:
        if not shape.has_text_frame:
            continue
        for para in shape.text_frame.paragraphs:
            for run in para.runs:
                if "{{NAME}}" in run.text:
                    run.text = run.text.replace("{{NAME}}", "Frank")
```
To delete a shape/placeholder: `sp = shape._element; sp.getparent().remove(sp)`.
If the template has more slots than your data, remove the extra shapes entirely
rather than leaving empty placeholders.

### Replace an image in place (keep size/position)
python-pptx has no direct setter; swap the bytes of the related image part. Read
the picture's `r:embed` rId off its `<a:blip>`, then overwrite the part's blob.
```python
from pptx.oxml.ns import qn

for shape in slide.shapes:
    if shape.shape_type == 13:  # MSO_SHAPE_TYPE.PICTURE
        blip = shape._element.find(".//" + qn("a:blip"))
        rid = blip.get(qn("r:embed"))
        with open("new.png", "rb") as f:
            shape.part.related_part(rid)._blob = f.read()
```

### Tables and charts
```python
from pptx.util import Inches

tbl = s.shapes.add_table(
    rows=2, cols=2, left=Inches(1), top=Inches(1), width=Inches(6), height=Inches(2)
).table
tbl.cell(0, 0).text = "Header"

from pptx.chart.data import CategoryChartData
from pptx.enum.chart import XL_CHART_TYPE

cd = CategoryChartData()
cd.categories = ["Q1", "Q2", "Q3"]
cd.add_series("Sales", (4.5, 5.5, 6.2))
s.shapes.add_chart(XL_CHART_TYPE.COLUMN_CLUSTERED, Inches(1), Inches(1), Inches(8), Inches(4.5), cd)
```
