office-export

office-export is a Windows-first Python CLI that exports Word, Excel, and PowerPoint documents through the installed desktop Microsoft Office applications. It creates native PDFs and consistent PNG or JPEG images. It can also rasterize PDF inputs without Office.

The core promise is faithful local rendering through the same Office applications that users rely on in the desktop UI. The CLI is designed for people, scripts, and coding agents.

Requirements

Office document export supports:

• Windows 11
• Microsoft 365 Apps desktop applications
• Office 2024 and Office LTSC 2024
• CPython 3.11 or newer
• uv and uvx

Office LTSC 2021 and older desktop releases are best effort. The CLI probes capabilities instead of rejecting an application only because of its version number.

Direct PDF rasterization works on any supported Python platform that has a compatible pypdfium2 wheel. Word, Excel, and PowerPoint are not required for PDF input.

This tool is intended for an interactive Windows user profile. It is not a server-side Office conversion service. First-run setup, modal dialogs, add-ins, Protected View, or an uninitialized Office license can block automation.

Install and run

Run the published package without a permanent installation:

uvx office-export --version
uvx office-export doctor

Run a local checkout during development:

$env:UV_LINK_MODE="copy"
uvx --refresh --from . office-export --version

Export documents

uvx office-export report.docx --to pdf
uvx office-export report.docx --to png --pages 1,3-5 --dpi 200
uvx office-export deck.pptx --to jpeg --slides 2-6 --dpi 200
uvx office-export model.xlsx --to pdf --sheet Summary --sheet "Q4 Charts"
uvx office-export model.xlsx --to png --range "Summary!A1:H40"
uvx office-export document.pdf --to jpeg --pages 1,3-5 --dpi 300

Use --output PATH to override the destination. Use --force to replace only the output files planned for the current conversion.

Default output names

• PDF is written beside the input as <name>.pdf.
• PNG files are written to <name> - PNG export.
• JPEG files are written to <name> - JPEG export.

Image names retain their logical source identity:

report-page-001.png
deck-slide-003.jpg
model-sheet-summary-page-001.png
model-sheet-summary-chart-revenue.png

Image output always uses a directory by default. An explicit image filename is accepted when the selection produces exactly one image.

Word

uvx office-export report.docx --to pdf --bookmarks headings
uvx office-export report.docx --to pdf --pages 2-5 --include-markup
uvx office-export report.docx --to png --pages 1,4,7

Word PDF bookmarks can come from headings, explicit Word bookmarks, or neither. The default is headings. The tool updates each table of contents in memory before export without saving the source. Use --no-update-toc to preserve the currently displayed values and pagination.

Contiguous page selection uses Word's native fixed-format range. Noncontiguous Word pages are supported for image output by rasterizing selected pages from a complete temporary PDF. Noncontiguous Word PDF output is rejected because combining PDFs can damage tags, links, destinations, metadata, and bookmarks.

PowerPoint

uvx office-export deck.pptx --to pdf --slides 1,3-5
uvx office-export deck.pptx --to png --output-type notes
uvx office-export deck.pptx --to pdf --output-type handout6
uvx office-export deck.pptx --to png --image-engine office

The default PDFium image engine renders the Office-created PDF. It provides consistent DPI, encoding, annotation, selection, notes, and handout behavior. The optional Office image engine calls PowerPoint's native slide export. It supports slide output only.

Inspection reports both one-based slide positions and stable PowerPoint slide IDs.

Excel

uvx office-export model.xlsx --to pdf --sheet Summary --sheet "Q4 Charts"
uvx office-export model.xlsx --to png --range "Summary!A1:H40"
uvx office-export model.xlsx --to png --charts all
uvx office-export model.xlsx --to jpeg --chart "Dashboard!Margin" --jpeg-quality 95

Repeated --sheet values accept exact names or one-based positions. A range uses SHEET!ADDRESS syntax. Excel chart selection creates one tightly bounded native chart image. JPEG charts are converted from Excel's temporary PNG so quality and background handling stay deterministic.

--dpi does not apply to native chart export. Chart dimensions come from the workbook. Excel can lose internal workbook links during native PDF conversion. External links emitted by Excel remain subject to Excel's own behavior.

The following options intentionally change how workbook content is evaluated:

• --recalculate auto|full
• --update-links
• --refresh-data

They are disabled by default.

PDF input

uvx office-export document.pdf --to png
uvx office-export document.pdf --to jpeg --pages 1,3-5 --dpi 300
uvx office-export document.pdf --to png --exclude-annotations

PDF input supports PNG and JPEG output. PDF-to-PDF rewriting is not supported. Physical page selectors are one-based. inspect also reports page labels when the PDF contains them.

Visible annotations and standard form appearances are rendered by default. --exclude-annotations also excludes form widget appearances. Dynamic XFA content produces a warning. Password-protected, encrypted, or permission-restricted PDFs are rejected.

Defaults:

• 150 DPI
• JPEG quality 92
• White JPEG background
• 50 megapixels per page

Use --max-megapixels only after reviewing the memory cost of the requested page size and DPI.

Inspect and diagnose

uvx office-export inspect report.docx --json
uvx office-export inspect deck.pptx --json
uvx office-export inspect model.xlsx --json
uvx office-export inspect document.pdf --json
uvx office-export doctor --json
uvx office-export doctor --smoke-word report.docx --smoke-excel model.xlsx --smoke-powerpoint deck.pptx --json
uvx office-export formats --json

doctor reports each Office application separately from PDFium. It also reports the Office version, bitness, active printer when available, Print Spooler state, installed printers, dependency versions, and temporary-directory access.

Smoke exports are opt-in. Supply one or more known local fixtures with --smoke-word, --smoke-excel, or --smoke-powerpoint.

JSON and manifests

Add --json to print a stable result object to stdout. Diagnostics stay on stderr. A successful conversion includes:

• Tool and schema versions
• Source size and SHA-256 hash
• Office application and version
• Active printer when relevant
• Effective options and warnings
• PDFium and Pillow versions
• Output paths, sizes, and SHA-256 hashes
• Logical source-to-output mappings
• Duration

Use --manifest PATH to persist the same result. Failed conversions also write a structured failure manifest when the requested manifest path is safe and writable. No sidecar manifest is created by default.

Batch conversion

uvx office-export batch .\incoming --to pdf
uvx office-export batch .\incoming --to png --recursive --continue-on-error --json

Batch conversion currently processes files sequentially and accepts only --jobs 1. Each Office source gets a fresh worker process and an isolated temporary directory.

Agent skill

Install the bundled managed skill:

uvx office-export skill install
uvx office-export skill install --skills-dir C:\custom\skills
uvx office-export skill remove

The default target is ~/.agents/skills/office-export/SKILL.md. Installation is idempotent and updates stale managed content. Installation and removal refuse unmanaged content unless --force is explicitly supplied.

The skill teaches agents to run diagnostics, inspect before selecting, export with JSON, review representative images, report exact paths and warnings, and preserve safe defaults.

Safety model

• Sources open read-only.
• VBA macros are force-disabled.
• AutoOpen and Auto_Open macros are not executed.
• External links do not update by default.
• Data connections do not refresh by default.
• Workbooks do not recalculate by default.
• Source changes are never saved.
• Passwords, Protected View, IRM, sensitivity restrictions, and PDF permissions are not bypassed.
• Final outputs are published only after conversion validation.
• A timeout can terminate only an Office process proven to have been created by the isolated worker.
• A pre-existing user Office process is never quit or terminated.

Office automation is not a security sandbox. Do not use it to open untrusted documents outside the protections of your Windows and Office environment.

Development

$env:UV_LINK_MODE="copy"
uv sync --all-groups
uv run ruff check .
uv run ruff format --check .
uv run pytest
uv run pytest -m office
uv build
uv run twine check dist/*

The default test run is cross-platform and excludes tests that require licensed desktop Office. Run the office marker in an interactive Windows session before release.

Known native limitations

• Office rendering can vary with Office updates, installed fonts, document compatibility settings, and printer metrics.
• Excel internal workbook links can be lost in native PDF output.
• PowerPoint-native images can differ slightly from PDFium images.
• Dynamic XFA forms may not match a full PDF viewer.
• Modal Office dialogs and add-ins can still interfere with automation.
