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.

OfficeCLI's built-in HTML rendering engine reproduces documents with high fidelity — and that's what gives AI eyes. It renders .docx / .xlsx / .pptx to HTML or PNG, closing the render → look → fix loop.

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.

For Developers — See It Live in 30 Seconds

# 1. Install (macOS / Linux) — or: brew install officecli / npm install -g @officecli/officecli
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

# Save and close — flushes the resident session to disk
officecli close deck.pptx
{
  "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"

Use Cases

For Developers:

For AI Agents:

For Teams:

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 via a package manager:

# Homebrew (macOS / Linux)
brew install officecli

# Scoop (Windows)
scoop install officecli

# npm (all platforms — fetches the native binary for your platform)
npm install -g @officecli/officecli

Or download manually from GitHub Releases:

Platform Binary
macOS Apple Silicon officecli-mac-arm64
macOS Intel officecli-mac-x64
Linux x64 officecli-linux-x64
Linux ARM64 officecli-linux-arm64
Windows x64 officecli-win-x64.exe
Windows ARM64 officecli-win-arm64.exe

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 — high-fidelity, built-in

OfficeCLI's keystone: a from-scratch, high-fidelity HTML rendering engine that lets an AI agent see the rendered document instead of guessing from the DOM. It covers shapes, charts (trendlines, error bars, waterfall, candlestick, sparklines), equations (OMML → LaTeX, rendered with KaTeX), 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:

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

350+ 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 spilling dynamic arrays (FILTER / SORT / UNIQUE / SEQUENCE / LET / LAMBDA / MAP), VLOOKUP / XLOOKUP / INDEX / MATCH, financial & bond math (XIRR / PRICE / YIELD / DURATION / COUPNUM), statistical distributions, tests & regression (NORM.DIST / T.TEST / LINEST), and date & text functions.

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

Round-trip dump — learn from existing docs

dump serializes any .docx, .pptx, or .xlsx — whole document or any subtree (a single paragraph, table, slide, worksheet, the styles part, numbering, theme, or settings) — into a replayable batch JSON; batch r

What is this?An open-source Office suite built for AI agents: it gives any AI agent full control over Word, Excel, and PowerPoint — reading, editing, and creating documents — right from the command line.
So is it a program I run, or a library I code against?A command-line tool, not a library: a single self-contained binary you run against .docx, .xlsx, and .pptx files. If you prefer not to touch a terminal, the AionUi desktop app drives it through natural language.
Do I need Microsoft Office or the .NET runtime installed first?No to both. The .NET runtime is embedded in the binary and no Office installation is required — the rendering and formula engines ship inside the binary itself.
Any gotchas I should know about?Two small ones: per-page PNG screenshots are made by piping rendered HTML through a headless browser, and updates are checked automatically in the background — turn that off with officecli config autoUpdate false or OFFICECLISKIPUPDATE=1.
Is it just for AI agents, or do humans use it too?Both. The README suggests developers automate reports and batch edits, teams clone templates and populate them with data, and agents generate presentations or pull structured data out of documents into JSON.
Does it work on Windows and Linux, or is it Mac-only?All three: there are prebuilt binaries for macOS (Apple Silicon and Intel), Linux (x64 and ARM64), and Windows (x64 and ARM64). Being self-contained, it also runs headless in Docker, CI, and on servers with no display.
Why does a CLI for Office files need a built-in rendering engine?So the agent can see what it makes: OfficeCLI renders .docx, .xlsx, and .pptx to high-fidelity HTML or per-page PNG, letting the agent check the layout and fix problems — the render, look, fix loop — even in CI or Docker on a machine with no display.
What can it actually change inside the files?Almost anything: text, fonts, colors, layout, formulas, charts, images. Highlights: Word tracked changes and TOC, Excel pivot tables plus 350+ formula functions evaluated on write, and PowerPoint animations, morph transitions, and 3D .glb models.
Does it support filling templates with data?Yes — merge replaces {{key}} placeholders in any .docx, .xlsx, or .pptx with JSON data, across paragraphs, table cells, shapes, headers, footers, and chart titles. Design a layout once, then fill it cheaply N times.
Can I preview edits live while I work?Yes — watch mode runs a local HTTP server with an auto-refreshing browser preview: every add, set, or remove command updates the page instantly. Excel watch even supports inline cell editing and drag-to-reposition charts.
