OfficeCLI

OfficeCLI is the world's first and the best Office suite designed for AI agents.

Give any AI agent full control over Word, Excel, and PowerPoint — in one line of code.

Open-source. Single binary. No Office installation. No dependencies. Works everywhere.

Built-in agent-friendly rendering engine — agents can see what they create, no Office required. Render .docx / .xlsx / .pptx to HTML or PNG, closing the render → look → fix loop anywhere the binary runs.

PPT creation process using OfficeCLI on AionUi

PowerPoint Presentations

—

Word Documents

—

Excel Spreadsheets

All documents above were created entirely by AI agents using OfficeCLI — no templates, no manual editing.

For AI Agents — Get Started in One Line

Paste this into your AI agent's chat — it will read the skill file and install everything automatically:

curl -fsSL https://officecli.ai/SKILL.md

That's it. The skill file teaches the agent how to install the binary and use all commands.

For Humans

Option A — GUI: Install AionUi — a desktop app that lets you create and edit Office documents through natural language, powered by OfficeCLI under the hood. Just describe what you want, and AionUi handles the rest.

Option B — CLI: Download the binary for your platform from GitHub Releases, then run:

officecli install

This copies the binary to your PATH and installs the officecli skill into every AI coding agent it detects — Claude Code, Cursor, Windsurf, GitHub Copilot, and more. Your agent can immediately create, read, and edit Office documents on your behalf, no extra configuration needed.

# 1. Install (macOS / Linux)
curl -fsSL https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.sh | bash
# Windows (PowerShell): irm https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.ps1 | iex
2. Create a blank PowerPoint
officecli create deck.pptx
3. Start live preview — opens http://localhost:26315 in your browser
officecli watch deck.pptx
4. Open another terminal, add a slide — watch the browser update instantly
officecli add deck.pptx / --type slide --prop title="Hello, World!"

That's it. Every add, set, or remove command you run will refresh the preview in real time. Keep experimenting — the browser is your live feedback loop.

Quick Start

# Create a presentation and add content
officecli create deck.pptx
officecli add deck.pptx / --type slide --prop title="Q4 Report" --prop background=1A1A2E
officecli add deck.pptx '/slide[1]' --type shape \
  --prop text="Revenue grew 25%" --prop x=2cm --prop y=5cm \
  --prop font=Arial --prop size=24 --prop color=FFFFFF
View as outline
officecli view deck.pptx outline
→ Slide 1: Q4 Report
→   Shape 1 [TextBox]: Revenue grew 25%
View as HTML — opens a rendered preview in your browser, no server needed
officecli view deck.pptx html
Get structured JSON for any element
officecli get deck.pptx '/slide[1]/shape[1]' --json

{
  "tag": "shape",
  "path": "/slide[1]/shape[1]",
  "attributes": {
    "name": "TextBox 1",
    "text": "Revenue grew 25%",
    "x": "720000",
    "y": "1800000"
  }
}

Why OfficeCLI?

What used to take 50 lines of Python and 3 separate libraries:

from pptx import Presentation
from pptx.util import Inches, Pt
prs = Presentation()
slide = prs.slides.add_slide(prs.slide_layouts[0])
title = slide.shapes.title
title.text = "Q4 Report"
# ... 45 more lines ...
prs.save('deck.pptx')

Now takes one command:

officecli add deck.pptx / --type slide --prop title="Q4 Report"

What OfficeCLI can do:

• Create documents from scratch -- blank or with content
• Read text, structure, styles, formulas -- in plain text or structured JSON
• Analyze formatting issues, style inconsistencies, and structural problems
• Modify any element -- text, fonts, colors, layout, formulas, charts, images
• Reorganize content -- add, remove, move, copy elements across documents

Word — full i18n & RTL support (per-script font slots, per-script BCP-47 lang tags lang.latin/ea/cs, complex-script bold/italic/size, direction=rtl cascading through paragraph/run/section/table/style/header/footer/docDefaults, rtlGutter + pgBorders shorthand, locale-aware page numbering for Hindi/Arabic/Thai/CJK), paragraphs, runs, tables, styles, headers/footers, images (PNG/JPG/GIF/SVG), equations, comments, footnotes, watermarks, bookmarks, TOC, charts, hyperlinks, sections, form fields, content controls (SDT), fields (22 zero-param types + MERGEFIELD / REF / PAGEREF / SEQ / STYLEREF / DOCPROPERTY / IF), OLE objects, document properties

Excel — cells (phonetic guide / furigana on add), formulas (150+ built-in functions with auto-evaluation, _xlfn. auto-prefix for dynamic-array functions), sheets (visible/hidden/veryHidden, print margins, printTitleRows/Cols, RTL sheetView, cascade-aware sheet rename), tables, sort (sheet / range, multi-key, sidecar-aware), conditional formatting, charts (including box-whisker, pareto with auto-sort + cumulative-%, log axis), pivot tables (multi-field, date grouping, showDataAs, sort, grandTotals, subtotals, compact/outline/tabular layout, repeat item labels, blank rows, calculated fields), slicers, named ranges, data validation, images (PNG/JPG/GIF/SVG with dual-representation fallback), sparklines, comments (RTL), autofilter, shapes, OLE objects, CSV/TSV import, $Sheet:A1 cell addressing

PowerPoint — slides (header/footer/date/slidenum toggles, hidden), shapes (pattern fill, blur effect, hyperlink tooltip + slide-jump links), images (PNG/JPG/GIF/SVG, fill modes: stretch/contain/cover/tile, brightness/contrast/glow/shadow), tables, charts, animations, morph transitions, 3D models (.glb), slide zoom, equations, themes, connectors, video/audio, groups, notes (RTL, lang), comments (RTL), OLE objects, placeholders (add/set by phType)

Use Cases

For Developers:

• Automate report generation from databases or APIs
• Batch-process documents (bulk find/replace, style updates)
• Build document pipelines in CI/CD environments (generate docs from test results)
• Headless Office automation in Docker/containerized environments

For AI Agents:

• Generate presentations from user prompts (see examples above)
• Extract structured data from documents to JSON
• Validate and check document quality before delivery

For Teams:

• Clone document templates and populate with data
• Automated document validation in CI/CD pipelines

Installation

Ships as a single self-contained binary. The .NET runtime is embedded -- nothing to install, no runtime to manage.

One-line install:

# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.sh | bash
Windows (PowerShell)
irm https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.ps1 | iex

Or download manually from GitHub Releases:

Verify installation: officecli --version

Or self-install from a downloaded binary (or run bare officecli to auto-install):

officecli install    # explicit
officecli            # bare invocation also triggers install

Updates are checked automatically in the background. Disable with officecli config autoUpdate false or skip per-invocation with OFFICECLI_SKIP_UPDATE=1. Configuration lives under ~/.officecli/config.json.

Key Features

Built-in Engines & Generation Primitives

OfficeCLI is self-contained. The capabilities below ship inside the binary — no Office required.

Rendering engine

A from-scratch agent-friendly rendering engine ships in the binary itself, covering shapes, charts (trendlines, error bars, waterfall, candlestick, sparklines), equations (OMML → MathJax-compatible), 3D .glb models via Three.js, morph transitions, slide zoom, and shape effects. Per-page PNG screenshots are produced by piping the rendered HTML through a headless browser. Three modes:

• view html — standalone HTML file, assets inlined. Open in any browser.
• view screenshot — per-page PNG, ready for multimodal agents to read.
• watch — local HTTP server with auto-refreshing preview; every add / set / remove updates the browser instantly. Excel watch supports inline cell editing and drag-to-reposition charts.

officecli view deck.pptx html -o /tmp/deck.html
officecli view deck.pptx screenshot -o /tmp/deck.png # add --page 1-N for more slides
officecli watch deck.pptx                            # http://localhost:26315

Without visualization, an agent generating slides is flying blind — it can read the DOM but can't tell if the title overflows or two shapes overlap. Because rendering is built into the binary, the render → look → fix loop works in CI, in Docker, on a server with no display — anywhere the binary runs.

Formula & pivot engine

150+ built-in Excel functions evaluated automatically on write — write =SUM(A1:A2), get the cell, the value is already there. No round-trip through Office to recalc. Covers dynamic-array functions (FILTER / UNIQUE / SORT / SEQUENCE with auto _xlfn. prefix), VLOOKUP / INDEX / MATCH, date & text functions, and 140+ more.

Plus native OOXML pivot tables from a source range with one command — multi-field rows/cols/filters, 10 aggregations, showDataAs modes, date grouping, calculated fields, top-N, layouts. Pivot cache + definition are written to OOXML, so Excel opens the file with the aggregation already populated:

officecli add sales.xlsx '/Sheet1' --type pivottable \
  --prop source='Data!A1:E10000' --prop rows='Region,Category' \
  --prop cols=Quarter --prop values='Revenue:sum,Units:avg' \
  --prop showDataAs=percentOfTotal

Template merge — generate once, fill many

merge replaces {{key}} placeholders in any .docx / .xlsx / .pptx with JSON data — across paragraphs, table cells, shapes, headers, footers, and chart titles. Agent designs the layout once (expensive); production code fills it N times (cheap, deterministic, zero token cost). Avoids the failure mode where an agent regenerates each report from scratch and produces N inconsistent layouts.

officecli merge invoice-template.docx out-001.docx '{"client":"Acme","total":"$5,200"}'
officecli merge q4-template.pptx q4-acme.pptx data.json

Round-trip dump — learn from existing docs

dump serializes any .docx — whole document or any subtree (a single paragraph, table, the styles part, numbering, theme, or settings) — into a replayable batch JSON; batch replays it. Given a sample the user wants to imitate, an agent reads the structured spec instead of raw OOXML XML, mutates, and replays. Bridges "I have an existing template" and "generate me 100 variations."

officecli dump existing.docx -o blueprint.json                  # whole document
officecli dump existing.docx /body/tbl[1] -o table.json         # any subtree
officecli batch new.docx --input blueprint.json

Resident Mode & Batch

For multi-step workflows, resident mode keeps the document in memory. Batch mode runs multiple operations in one open/save cycle.

# Resident mode — near-zero latency via named pipes
officecli open report.docx
officecli set report.docx /body/p[1]/r[1] --prop bold=true
officecli set report.docx /body/p[2]/r[1] --prop color=FF0000
officecli close report.docx
Batch mode — atomic multi-command execution (stops on first error by default)
echo '[{"command":"set","path":"/slide[1]/shape[1]","props":{"text":"Hello"}},
{"command":"set","path":"/slide[1]/shape[2]","props":{"fill":"FF0000"}}]' 

| officecli batch deck.pptx --json
Inline batch with --commands (no stdin needed)
officecli batch deck.pptx --commands '[{"op":"set","path":"/slide[1]/shape[1]","props":{"text":"Hi"}}]'
Use --force to continue past errors
officecli batch deck.pptx --input updates.json --force --json

Three-Layer Architecture

Start simple, go deep only when needed.

# L1 — high-level views
officecli view report.docx annotated
officecli view budget.xlsx text --cols A,B,C --max-lines 50
L2 — element-level operations
officecli query report.docx "run:contains(TODO)"
officecli add budget.xlsx / --type sheet --prop name="Q2 Report"
officecli move report.docx /body/p[5] --to /body --index 1
L3 — raw XML when L2 isn't enough
officecli raw deck.pptx '/slide[1]'
officecli raw-set report.docx document 

--xpath "//w:p[1]" --action append 

--xml '<w:r><w:t>Injected text</w:t></w:r>'

AI Integration

MCP Server

Built-in MCP server — register with one command:

officecli mcp claude       # Claude Code
officecli mcp cursor       # Cursor
officecli mcp vscode       # VS Code / Copilot
officecli mcp lmstudio     # LM Studio
officecli mcp list         # Check registration status

Exposes all document operations as tools over JSON-RPC — no shell access needed.

Direct CLI Integration

Get OfficeCLI working with your AI agent in two steps:

1. Install the binary -- one command (see Installation)
2. Done. OfficeCLI automatically detects your AI tools (Claude Code, GitHub Copilot, Codex) by checking known config directories and installs its skill file. Your agent can immediately create, read, and modify any Office document.

curl -fsSL https://officecli.ai/SKILL.md

curl -fsSL https://officecli.ai/SKILL.md -o ~/.claude/skills/officecli.md

Why your agent will thrive on OfficeCLI

• Deterministic JSON output — every command supports --json with consistent schemas. No regex parsing, no scraping stdout.
• Path-based addressing — every element has a stable path (/slide[1]/shape[2]). Agents navigate documents without understanding XML namespaces. (OfficeCLI syntax: 1-based indexing, element local names — not XPath.)
• Progressive complexity (L1 → L2 → L3) — agents start with read-only views, escalate to DOM ops, fall back to raw XML only when needed. Minimizes token usage.
• Self-healing workflow — validate, view issues, and the structured error codes (not_found, invalid_value, unsupported_property) return suggestions and valid ranges. Agents self-correct without human intervention.
• Built-in agent-friendly rendering engine — view html / view screenshot / watch emit HTML and PNG natively. No Office required. Agents can see their output and fix layout issues, even inside CI / Docker / headless environments.
• Built-in formula & pivot engine — 150+ Excel functions auto-evaluated on write; native OOXML pivot tables from a source range with one command. Agents read computed values and shipped aggregations immediately, without round-tripping through Office.
• Template merge — agent designs the layout once, downstream code fills {{key}} placeholders N times. Avoids burning tokens regenerating every report from scratch.
• Round-trip dump — dump turns any .docx into replayable batch JSON. Agents learn from human-authored samples by reading a structured spec, not raw OOXML XML.
• Built-in help — when unsure about property names or value formats, the agent runs officecli <format> set <element> instead of guessing.
• Auto-install — OfficeCLI detects your AI tooling (Claude Code, Cursor, VS Code, …) and configures itself. No manual skill-file setup.

Built-in Help

Don't guess property names — drill into the help:

officecli pptx set              # All settable elements and properties
officecli pptx set shape        # Detail for one element type
officecli pptx set shape.fill   # One property: format and examples
officecli docx query            # Selector reference: attributes, :contains, :has(), etc.

Run officecli --help for the full overview.

JSON Output Schemas

All commands support --json. The general response shapes:

Single element (get --json):

{"tag": "shape", "path": "/slide[1]/shape[1]", "attributes": {"name": "TextBox 1", "text": "Hello"}}

List of elements (query --json):

[
  {"tag": "paragraph", "path": "/body/p[1]", "attributes": {"style": "Heading1", "text": "Title"}},
  {"tag": "paragraph", "path": "/body/p[5]", "attributes": {"style": "Heading1", "text": "Summary"}}
]

Errors return a non-zero exit code with a structured error object including error code, suggestion, and valid values when available:

{
  "success": false,
  "error": {
    "error": "Slide 50 not found (total: 8)",
    "code": "not_found",
    "suggestion": "Valid Slide index range: 1-8"
  }
}

Error codes: not_found, invalid_value, unsupported_property, invalid_path, unsupported_type, missing_property, file_not_found, file_locked, invalid_selector. Property names are auto-corrected -- misspelling a property returns a suggestion with the closest match.

Error Recovery -- Agents self-correct by inspecting available elements:

# Agent tries an invalid path
officecli get report.docx /body/p[99] --json
# Returns: {"success": false, "error": {"error": "...", "code": "not_found", "suggestion": "..."}}
Agent self-corrects by checking available elements
officecli get report.docx /body --depth 1 --json
Returns the list of available children, agent picks the right path

Mutation confirmations (set, add, remove, move, create with --json):

{"success": true, "path": "/slide[1]/shape[1]"}

See officecli --help for full details on exit codes and error formats.

End-to-End Workflow Example

A typical self-healing agent workflow: create a presentation, populate it, verify, and fix issues -- all without human intervention.

# 1. Create
officecli create report.pptx
2. Add content
officecli add report.pptx / --type slide --prop title="Q4 Results"
officecli add report.pptx '/slide[1]' --type shape 

--prop text="Revenue: $4.2M" --prop x=2cm --prop y=5cm --prop size=28
officecli add report.pptx / --type slide --prop title="Details"
officecli add report.pptx '/slide[2]' --type shape 

--prop text="Growth driven by new markets" --prop x=2cm --prop y=5cm
3. Verify
officecli view report.pptx outline
officecli validate report.pptx
4. Fix any issues found
officecli view report.pptx issues --json
Address issues based on output, e.g.:
officecli set report.pptx '/slide[1]/shape[1]' --prop font=Arial

Units & Colors

All dimension and color properties accept flexible input formats:

Common Patterns

# Replace all Heading1 text in a Word doc
officecli query report.docx "paragraph[style=Heading1]" --json | ...
officecli set report.docx /body/p[1]/r[1] --prop text="New Title"
Export all slide content as JSON
officecli get deck.pptx / --depth 2 --json
Bulk-update Excel cells
officecli batch budget.xlsx --input updates.json --json
Import CSV data into an Excel sheet
officecli add budget.xlsx / --type sheet --prop name="Q1 Data" --prop csv=sales.csv
Template merge for batch reports
officecli merge invoice-template.docx invoice-001.docx '{"client":"Acme","total":"$5,200"}'
Check document quality before delivery
officecli validate report.docx && officecli view report.docx issues --json

From Python — wrap once, get parsed JSON back from every call:

import json, subprocess
def cli(*args):
return json.loads(subprocess.check_output(["officecli", *args, "--json"], text=True))
cli("create", "deck.pptx")
cli("add", "deck.pptx", "/", "--type", "slide", "--prop", "title=Q4 Report")
slide = cli("get", "deck.pptx", "/slide[1]")
print(slide["attributes"]["text"])
