WolfPPT

Edit existing PowerPoint .pptx decks from Python with a python-pptx-style API and keep every part you did not touch, including themes, layouts, masters, charts, media, and notes, byte-for-byte identical. WolfPPT is MIT licensed and also creates new decks.

pip install wolfppt

Replace a placeholder in a deck your team already maintains, keeping that run's formatting, then update a table cell:

from wolfppt import Presentation

prs = Presentation("monthly_review.pptx")
for slide in prs.slides:
    for shape in slide.shapes:
        if not shape.has_text_frame:
            continue
        for paragraph in shape.text_frame.paragraphs:
            for run in paragraph.runs:
                if "{{month}}" in run.text:
                    run.text = run.text.replace("{{month}}", "September")

table = next(s for s in prs.slides[1].shapes if s.has_table).table
table.cell(1, 1).text = "$4.2M"
prs.save("monthly_review_updated.pptx")

The saved copy rewrites only the two edited slide parts. Task guides for text, tables, and chart data are on wolfppt.com.

• Lossless .pptx / .pptm package preservation: parts you did not edit, including parts WolfPPT has no schema for, stay byte-for-byte identical.
• Guarded text, shape, table, chart, and slide operations (edit, duplicate, delete, reorder) with mutation guards that refuse unsafe edits instead of writing them.
• Verification receipts, semantic diffs, and optional Open XML validation and render smoke check every claimed edit against the saved package.

The benchmark harness in this repository measures these claims and stays a first-class part of the project.

Compared with python-pptx

• API shape: the facade mirrors python-pptx names (Presentation, slides, shapes, text_frame, runs, table.cell(...)) for the operations it covers and runs without python-pptx installed.
• Preservation: python-pptx saves the slide, layout, master, notes, and chart parts it models by serializing their XML again. On the checked-in fixtures, a python-pptx 1.0.2 open-and-save round trip rewrote the chart parts and [Content_Types].xml of decks with charts; the same round trip through WolfPPT left every part byte-identical.
• Speed: sdk-preservation run 20260519T034127Z (see Benchmark Suite) measured WolfPPT round trips 2.006x to 561.911x faster than the open-source baselines, python-pptx among them.
• Coverage: python-pptx has the broader API, and WolfPPT wheels cover CPython 3.11-3.14 on Linux x86_64/aarch64 and macOS arm64. Check the compatibility matrix for each call a script relies on, and keep python-pptx for APIs it does not list.

Quickstart

Install the latest release from PyPI with pip install wolfppt, or install a source checkout with pip install .. Add the baseline extra (pip install wolfppt[baseline]) for the wolfppt-harness command, which needs python-pptx for adapter comparison lanes.

Then run the built-in demo:

wolfppt demo

It builds a deterministic deck, applies four surgical edits, reopens the saved package to verify every edit, and prints a verification receipt:

requested edits: 4
verified edits: 4
unrelated package parts changed: 0
reopen: passed
open xml validation: skipped (Open XML validation is optional and is not run by the demo.)

Create a new deck:

from wolfppt import Presentation

prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[6])
prs.save("output.pptx")

Harness Shape

The harness is WolfPPT's evidence system. It generates a deterministic fixture corpus, records the expected package semantics, and pushes every adapter — including the native Rust engine behind the public API — through validation, package diffing, semantic diffing, and render smoke. Results append to an append-only evidence ledger and roll up into a generated compatibility matrix:

fixtures/*.pptx
   |
   v
semantic extractor -> expected/*.json
   |
   v
library adapters -> validation / package diff / semantic diff / render smoke
   |
   v
results/runs.jsonl -> generated compatibility matrix

Benchmark Suite

wolfppt-harness benchmark runs repeatable adapter benchmarks across the checked-in fixture manifest. It records latency separately from correctness checks, so semantic diffs, package diffs, and optional Open XML validation do not inflate the measured adapter time. The default suite compares the stdlib semantic extractor, python-pptx summary/round-trip baselines, the official .NET Open XML SDK, a PptxGenJS generation-only lane, an Apache POI round-trip lane when its toolchain is installed, an opt-in external command round-trip lane for other SDKs, the Rust CLI bridge, and the native Rust Python binding when those tools are available. Use --validate-openxml for release-grade output validation and --write-results to append samples to results/runs.jsonl. The PptxGenJS lane is a generated-deck baseline, not evidence of existing-deck preservation; Open XML validation may surface schema differences separately from generation speed.

Drop-in edit benchmarks are opt-in because they target specific public API workflows instead of the whole fixture corpus. Use them to compare equivalent python-pptx and WolfPPT facade edits, such as paragraph and table-cell updates. For performance claims against Python libraries, build the native module in release mode first; debug editable builds are useful for development but slower.

Use wolfppt-harness benchmark-profiles to list curated benchmark suites and wolfppt-harness benchmark-profile <name> to run one. Profiles keep drop-in comparisons on valid adapter/fixture pairs and add a python-pptx vs WolfPPT speedup table when both sides pass. Use dev-smoke for fast edit-loop feedback; it is not claim-grade evidence. Useful profiles include dev-smoke, core-smoke, core-full, real-corpus, private-real-decks, sdk-preservation, sdk-comparison, dropin-smoke, dropin-full, release-smoke, and release-full. Core and release profiles use built-in preservation adapters only; Apache POI claim gates belong in sdk-preservation, custom external commands belong in sdk-comparison, stricter external-command setup proof belongs in sdk-comparison-strict, and uncommitted local or VPS-only decks belong in private-real-decks via WOLFPPT_PRIVATE_DECKS_DIR. Release profiles omit the generation-only PptxGenJS lane so --validate-openxml stays strict for existing-deck edit and round-trip lanes. Add --min-wolfppt-speedup 1.0 to turn passing python-pptx/WolfPPT pairs into a performance gate for release evidence. The gate still reports every near miss, but sub-threshold slowdowns of 0.100 ms or less are treated as timing noise rather than material failures. Add --require-adapter <name> when a comparison lane must be present rather than skipped, for example when recording external SDK evidence. For visual-oracle corpus evidence, pair run-corpus --include-powerpoint with --require-lane powerpoint-render so a missing or skipped PowerPoint export fails the run instead of being treated as optional. Add --min-powerpoint-exported-slides <count> to gate the actual slide PNG sample count.

See the compatibility matrix under docs/compatibility/ for the current feature-coverage boundaries. As of the latest release-gate evidence, release-full run 20260519T120111Z passes the full checked-in release gate with 483 passing rows, 0 skips, 0 failures, 29 distinct fixtures, and 5,040 Open XML validation samples, plus fixture gates for 110 slides, 290 shapes, 25 charts, 16 fixtures with tables, 16 with charts, 14 with media, and 17 with embedded objects. This release gate was refreshed after adding the procurement vendor-risk pack and the one-pass grouped-connector connection, slide-level connector-to-new-shape, and nested-group OLE insertion paths, then refreshed again after coalescing grouped connector attachments to newly added group children. It includes connector attachment edits through begin_connect() and end_connect() for newly added, existing deck, and grouped child shapes, grouped-shape child adjustment edits, grouped existing-shape and grouped existing-child lanes, table row-height and column-width edits, bar/line/pie chart-add lanes, packaged native chart templates, batched chart-template-family insertion, coalesced nested-group auto-shape insertion, speaker-notes text, text-frame, background, paragraph/run, placeholder-clone, and slide-name metadata lanes, and Linux fit_text coverage through a discovered compatible font file. The latest evidence-backed real-corpus run 20260527T121753Z passes 144/144 rows across sixteen real-world-style fixtures, including the QoE diligence, customer success, security compliance, revenue-operations forecast, product-launch readiness, enterprise implementation, procurement vendor-risk, post-merger integration, and earnings board appendix packs (workloads/post_merger_integration_pack and workloads/earnings_board_appendix_pack), with 960 Open XML validation samples and the 16-fixture gate plus slide, shape, table, chart, media, and embedded-object complexity coverage. The report records Git metadata from the remote launcher environment for commit 3d6134b, so the raw benchmark report and detached job point at the same code. New launcher runs also record whether the VPS mirror was freshly synced before benchmarking. Local PowerPoint visual-oracle run 20260519T053625Z passes the required powerpoint-render lane across the current 29-fixture corpus and exports 110 slide PNGs. A redacted remote-host private-real-decks pressure run 20260518T050715Z passes on two distinct private decks with 16 slides, 135 shapes, 8 tables, 4 charts, 13 media parts, 120 Open XML validation samples, and 0 raw-name/path leaks in the private report check. The latest remote-host sdk-preservation run 20260519T034127Z passes 56/56 rows across python-pptx, Open XML SDK, Apache POI, and WolfPPT native with 840 Open XML validation samples, 42 SDK preservation comparisons, and 2.006-561.911x measured WolfPPT speedups against those open-source baselines. These support checked-in corpus, open-source SDK, and narrow private-pressure claims through those snapshots, but not universal "best in class" claims or first-of-kind claims.

Python-Compatible Facade

WolfPPT exposes a first python-pptx-style API for existing-deck edits:

picture.crop_left = 0.125
prs.slides[0].shapes[0].table.cell(1, 1).text = "2"
prs.slides[0].shapes.add_table(2, 3, 0, 0, 2743200, 914400)
prs.save("updated.pptx")

The facade currently supports existing-deck open/save, slide and shape iteration/indexing, common collection slicing, title placeholder lookup, slide.placeholders, slide.shapes.placeholders, shape-tree helper flags, slide layouts, read-only .part package metadata, read-only .element XML inspection for common presentation, slide, layout, shape, placeholder, and master objects, background fill reads and slide background writes, existing notes slide/master reads, slides.add_slide(layout), slides.move(...), slides.duplicate(slide) including chart, notes, OLE, comment, audio/video/media, and external-target relationship copy policies, slides.remove(slide), del slides[index], and del slides[start:stop:step] for persisted and pending newly-added or duplicated slides, slide_layouts.remove(...), shapes.add_picture(...) with explicit or inferred bounds, picture crop reads/writes, shapes.add_textbox(...), common shapes.add_shape(...) preset shapes, table insertion, table cell text-frame/margin reads/writes, table row/column insert and remove, shapes.remove(...), group.shapes.remove(child) including any-depth nested group children and whole sub-groups, chart insertion, chart type/series/title/legend/axis reads, chart title, legend, and axis-title edits, category/XY/bubble chart data replacement, text reads, shape.text assignment, shape name, type, geometry, rotation, adjustment, and line XML helper reads/writes, solid/gradient fill, line RGB, and line width writes, shadow inheritance, external hyperlink, and target-slide reads/writes, paragraph/run text assignment, text-run external hyperlinks, text-frame margin, word-wrap, vertical-anchor, auto-size, and fit-text reads/writes, paragraph alignment, level, and spacing reads/writes, run bold/italic/underline reads/writes, run size/name/color reads/writes, paragraph/run appends, shape.text_frame.clear(), and shape.text_frame.text assignment. Edited saves go through the native Rust mutation engine; no-op saves preserve the source package.

uv run maturin develop --manifest-path crates/wolfppt-py/Cargo.toml
uv run maturin develop --release --manifest-path crates/wolfppt-py/Cargo.toml

For performance claims involving wolfppt_native, rebuild the PyO3 module with uv run maturin develop --release --manifest-path crates/wolfppt-py/Cargo.toml before running benchmarks. Debug native builds are useful for development, but their timings are not benchmark evidence. For private corpora with source-invalid decks, add --min-source-invalid-preserved-samples N to the private-real-decks profile alongside --validate-openxml before claiming that WolfPPT preserves those exact validator failures.

• deterministic Phase 1 fixture corpus generator using python-pptx-authored valid packages
• normalized package manifest and diff commands
• optional python-pptx baseline summary and round-trip commands
• Open XML SDK validator project and CLI wrapper
• LibreOffice PDF render smoke command
• corpus runner with semantic oracle, Open XML validation, optional python-pptx round-trip, optional LibreOffice render, Markdown/JSON reports, and append-only result rows

• native Python access to the Rust typed presentation summary
• Rust-vs-Python semantic parity comparison for typed native summaries
• Rust CLI and native binding package round-trip lanes that prove part-level preservation with semantic and package diffs
• explicit OLE object fixture coverage for slide-level oleObject relationships and embedded binary preservation
• Rust CLI and native binding blank-slide append using either the first slide's layout relationship or a selected existing layout index, with editable placeholder materialization, corpus mutation lanes checking slide count, package delta, and Open XML validation when the validator is available
• Rust CLI and native binding exact slide-text replacement across all slides or scoped to a selected slide index, selected text-run replacement, and selected shape-level text setting with newline-separated text-frame paragraphs, plus selected paragraph text setting while preserving unrelated package parts

Release readiness

Public releases are cut with the operator checklist in docs/release/PUBLISH_CHECKLIST.md: freeze the candidate commit, produce the platform evidence card with wolfppt-harness release-candidate --strict, gate on a green detached claims job at the exact frozen head, and only then publish. The checklist defines the full gate order and the evidence to record at each step.
