wordlive

Drive a running Microsoft Word instance from Python — xlwings, but for Word. Built for both human scripting and LLM agents. Windows-only.

Install

pip install wordlive

# Add to a python project
uv add wordlive

# Or as a `uv` tool
uv tool install wordlive

(Requires Python 3.10+ and pywin32 on Windows.)

Rendering pages to PNG (snapshot) needs the optional snapshot extra, which pulls in PyMuPDF:

pip install "wordlive[snapshot]"
uv add "wordlive[snapshot]"

Python

import wordlive as wl

with wl.attach() as word:
    doc = word.documents.active

    # Reads
    outline = doc.outline()
    bookmarks = doc.bookmarks.list()

    # See it the way a vision model would — render a section to PNG
    # (needs `wordlive[snapshot]`):
    png = doc.heading("Introduction").snapshot()[0].png

    # Polite writes — preserves the user's cursor and view, atomic Ctrl-Z.
    with doc.edit("Update address block"):
        doc.bookmarks["Address"].set_text("123 Main St")
        doc.content_controls["Signatory"].set_text("Jane Doe")
        doc.heading("Introduction").insert_paragraph_after("New context paragraph.")

    # Hand back a deliverable (the Python API is ungated):
    doc.export_pdf("report.pdf")

CLI

JSON in, JSON out — designed to drop straight into an LLM tool-use loop:

wordlive status
wordlive outline                  # heading structure (heading:N)
wordlive outline --all            # every paragraph (para:N) — alias of `paragraphs`
wordlive paragraphs               # same: para:N, level, offsets, text
wordlive read bookmark Address
wordlive write bookmark Address --text "123 Main St"

# Insert a new paragraph relative to ANY anchor (heading, paragraph, bookmark, …):
wordlive insert --anchor-id heading:1 --text "..."          # after (default)
wordlive insert --anchor-id para:3 --text "..." --before
wordlive insert --anchor-id end --runs '[{"text":"Bold lead","bold":true},{"text":" — rest"}]'

# Drop a whole styled section in ONE op (item text takes **bold**/*italic* markdown):
wordlive insert-block --anchor-id heading:1 --items \
    '[{"text":"**Politeness** first.","style":"List Bullet"},"Atomic undo."]'
#   → reports range:START-END; then: wordlive list apply --anchor-id range:… --type bulleted

# Or hand it constrained Markdown and get real headings/lists/paragraphs (a subset, not CommonMark):
printf '# Plan\n\nKick-off.\n\n- scope it\n- staff it\n' | wordlive insert-markdown --anchor-id end --markdown -
#   insert-section adds a heading + body in one op; replace-section --anchor-id heading:N rewrites a section's body

# Append / prepend at the very end / start of the document (no anchor needed):
wordlive append  --text "Closing note."                     # new final paragraph
wordlive prepend --text "DRAFT" --inline                    # join the first paragraph

# Address anchors by ID (the IDs `outline`/`paragraphs` emit — `heading:N`, `para:N`, `bookmark:NAME`, `cc:NAME`):
wordlive replace --anchor-id heading:3 --text "Updated section text"
wordlive go-to --anchor-id bookmark:Address

# Explicit cursor surface (the non-preferred mode — deliberately moves the cursor):
wordlive cursor read                              # where is the cursor? which para:N?
wordlive cursor write --text "inserted here"      # type at the cursor

# Styles + paragraph formatting (atomic-undo):
wordlive style list
wordlive style apply --anchor-id heading:3 --name "Heading 2"
wordlive format-paragraph --anchor-id heading:3 --alignment center --space-before 6

# Tables (cells are anchors: table:N:R:C):
wordlive table list
wordlive table read 1
wordlive table records 1                                   # body rows as {header: value} dicts
wordlive replace --anchor-id table:1:2:2 --text "$450"
wordlive table add-row --table 1 --values '["Lodging", "$600"]'
wordlive table append-record --table 1 --record '{"Item":"Lodging","Cost":"$600"}'  # by header name
wordlive table update-row --table 1 --key Travel --values '{"Cost":"$450"}'         # match a row by content
wordlive table create --anchor-id end --data '[["Item","Cost"],["Travel","$400"]]' --header
wordlive table create --anchor-id end \
    --data '[{"Item":"Travel","Cost":"$400"}]'             # records → keys are a header row
#   --rows/--cols are inferred from --data (give them only to pad larger)
wordlive table delete 2

# Page / column / section breaks (explicit one-off mark; for a style use --page-break-before):
wordlive insert-break --anchor-id heading:3 --kind page
wordlive format-paragraph --anchor-id heading:3 --page-break-before

# Collaboration: comments + track changes (the polite, non-destructive surface):
wordlive comment add --anchor-id heading:3 --text "Please expand this." --author Bot
wordlive comment list
wordlive comment resolve --index 1
wordlive track on            # record edits as revisions; `track off` to stop
wordlive revisions           # read the tracked changes back (type/author/text/range)
# …and `wordlive snapshot --markup all` renders those changes as visible marks.

# Non-visual layout introspection (reason about pages without a snapshot):
wordlive stats               # pages/words/…/tables/images/comments + saved, one read
wordlive locate --anchor-id heading:8   # {page, end_page, line, column, in_table}

# Lists & numbering (any anchor's paragraphs):
wordlive list apply --anchor-id heading:6 --type numbered
wordlive list restart --anchor-id heading:6

# Sections, headers & footers (header:S:WHICH / footer:S:WHICH):
wordlive sections
wordlive header write --section 1 --text "ACME Corporation"
wordlive footer read --section 1

# Images — from a file or base64 (--wrap is required: inline | auto | square | …):
wordlive insert-image --anchor-id heading:3 --path diagram.png --wrap auto
base64 logo.png | wordlive insert-image --anchor-id bookmark:Logo --base64 - --wrap inline --width 96

# …and read embedded pictures back out (image:N ids; for a vision model):
wordlive images                                            # list every embedded picture
wordlive read-image --anchor-id image:1 --out logo.png     # extract bytes + mime

# Equations — UnicodeMath (native), LaTeX (needs the `latex` extra), or MathML:
wordlive insert-equation --anchor-id heading:3 --unicodemath "x=(-b±√(b^2-4ac))/(2a)"
wordlive insert-equation --anchor-id heading:3 --latex "\frac{-b}{2a}"   # pip install "wordlive[latex]"
wordlive equations                                         # list equation:N ids, type, preview

# Snapshot — render page(s) to PNG so a vision model can SEE the layout
# (needs the `snapshot` extra: pip install "wordlive[snapshot]"):
wordlive snapshot --anchor-id heading:3 --out section.png   # the section's page(s)
wordlive snapshot --page 2 --out p2.png                     # one page
wordlive snapshot --pages 1-3                               # base64 PNGs inline (JSON)
wordlive snapshot --max-dim 1000                            # whole doc, low-res layout check

# Batch multiple ops in a single Ctrl-Z:
wordlive exec --script ops.json

# Save / hand back a deliverable — GATED behind a directory whitelist
# (--save-dir or WORDLIVE_SAVE_DIRS; with none set, saving is off):
wordlive --save-dir C:\out save-as C:\out\report.docx
wordlive --save-dir C:\out export-pdf C:\out\report.pdf    # pixel-faithful PDF

Where ops.json looks like:

{
  "label": "Update report",
  "ops": [
    {"op": "write_bookmark", "name": "Address", "text": "123 Main St"},
    {"op": "write_cc", "name": "Signatory", "text": "Jane Doe"},
    {"op": "insert_paragraph", "anchor_id": "heading:3", "text": "New risk paragraph."},
    {"op": "replace", "anchor_id": "heading:3", "text": "Updated section text"},
    {"op": "apply_style", "anchor_id": "heading:3", "name": "Heading 2"},
    {"op": "format_paragraph", "anchor_id": "heading:3", "alignment": "center", "space_before": 6}
  ]
}

Exit codes: 0 ok, 1 other, 2 anchor-not-found, 3 Word-busy, 4 Word-not-running, 5 ambiguous-match (replace --find hit several).

Agent skills

Setting up a specific tool (Claude Code, Claude Desktop, Cursor, …)? The Agents & LLM tools guide has copy-paste setup per client.

wordlive ships two LLM-facing skills (SKILL.md): wordlive-cli (the command-line workflow) and wordlive-python (the import wordlive as wl API). Each covers the anchor model, every verb, and the exit-code / exception contract.

An agent that hits wordlive --help is pointed straight at wordlive llm-help, which prints the whole guide to stdout in one shot — no install step, no Word:

wordlive llm-help                 # the CLI guide
wordlive llm-help --python        # the Python-API guide

Or drop the skill files into a project or your home directory so coding tools discover them on their own (CLI skill by default; --python for just Python, --both for both):

wordlive install-skill            # ./.agents/skills/wordlive-cli/SKILL.md
wordlive install-skill --both     # also drops wordlive-python/SKILL.md
wordlive install-skill --system   # into ~/.agents/skills/ instead

MCP server (Claude Desktop & other agents)

Prefer MCP? wordlive ships a server so Claude Desktop and other MCP clients can drive your open document directly. Three ways to set it up, easiest first:

1. One-click bundle. Download wordlive.mcpb (built from mcpb/) and drop it onto Claude Desktop → Settings → Extensions.

2. install-mcp. Register the server in your client's config in one command (it uses uvx, so there's no separate install step):

wordlive install-mcp                      # → Claude Desktop's config
wordlive install-mcp --client claude-code # → ./.mcp.json
wordlive install-mcp --print              # just print the JSON snippet

3. By hand. pip install "wordlive[mcp,snapshot]" (the snapshot extra adds the vision tool), then add to claude_desktop_config.json:

{ "mcpServers": { "wordlive": { "command": "wordlive-mcp" } } }

It exposes four dispatch tools — word_read, word_write, word_exec, and word_snapshot (which returns a rendered page as an image). The full op vocabulary and anchor model are in the one-page guide, fetchable as a tool call with word_read(command="guide") (also the wordlive://guide resource). Word must be running on the same Windows machine. See docs/mcp.md.

Examples

Runnable, out-of-the-box scripts live in examples/ — Python (using the library) and PowerShell (driving the CLI). Each attaches to the document you already have open; the read-only and append-only ones are safe to try on a real document.

python examples/python/read_outline.py            # read-only: print the outline
python examples/python/append_note.py "Reviewed." # append one paragraph (atomic, polite)

.\examples\powershell\Show-Outline.ps1
.\examples\powershell\Invoke-WordliveWithRetry.ps1 write bookmark Address --text "123 Main St"

Design

• Politeness first — operations preserve the user's Selection, view, and scroll. The user keeps editing alongside you.
• Semantic anchors over Selection — operations target bookmarks, content controls, or headings — never the live cursor unless you ask.
• Atomic undo — every doc.edit() opens a Word UndoRecord, so a single Ctrl-Z reverts the whole block.
• Escape hatch — every wrapper exposes .com for the raw COM object; you're never blocked by missing coverage.

See spec.md for the full design.
