OfficeCLI is a standalone command-line Office suite that lets AI agents read, edit, render, and automate Word, Excel, and PowerPoint files without requiring Microsoft Office. Developers and other users employ it to create and inspect documents through commands, with HTML or PNG rendering supporting visual review. The catalogue skills teach coding agents how to install and use OfficeCLI.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Supply Chain · line 12 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
- high Tool Misuse · line 462 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00119 | $0.09228 |
| Opus 5.5 | $0.00048 | $0.03691 |
| Sonnet 5.5 | $0.00024 | $0.01846 |
| Haiku 4.5 | $0.00012 | $0.00923 |
Grade C, and why
officecli-xlsx scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

OfficeCLI XLSX Skill
Setup
If officecli is missing:
- macOS / Linux:
curl -fsSL https://d.officecli.ai/install.sh | bash - Windows (PowerShell):
irm https://d.officecli.ai/install.ps1 | iex
Verify with officecli --version (open a new terminal if PATH hasn't picked up). If install fails, download a binary from https://github.com/iOfficeAI/OfficeCLI/releases.
⚠️ Help-First Rule
This skill teaches what good xlsx looks like, not every command flag. When a property name, enum value, or alias is uncertain, consult help BEFORE guessing.
officecli help xlsx # List all xlsx elements
officecli help xlsx <element> # Full element schema (e.g. pivottable, chart, cf)
officecli help xlsx <verb> <element> # Verb-scoped (e.g. add chart, set cell)
officecli help xlsx <element> --json # Machine-readable schema
Help reflects the installed CLI version. When this skill and help disagree, help is authoritative.
Shell & Execution Discipline
Shell quoting (zsh / bash). Excel paths contain [], and number formats contain $. Both are shell metacharacters. Rules:
- ALWAYS quote element paths:
"/Sheet1/row[1]", not/Sheet1/row[1]. - Use single quotes for any prop value containing
$:numFmt='$#,##0'. - For formulas with cross-sheet
!references, usebatchwith a<<'EOF'heredoc (see Known Issues). \nand\tin a prop value ARE interpreted by the CLI —\nis a real in-cell line break (pair with--prop wrapText=true),\ta tab — consistent across xlsx / docx / pptx. Double them (\\n) for a literal backslash-n (rarely wanted). ($is the shell layer above — single-quote it.)
Incremental execution. Run commands one at a time and read each exit code. officecli mutates the file on every call; a 50-command script that fails at command 3 will cascade silently. One command → check output → continue.
Requirements for Outputs
Before reaching for a command, know what a good xlsx looks like. These are the deliverable standards every workbook MUST meet.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

officecli-xlsx is a skill published in the GitHub repository iOfficeAI/OfficeCLI (32,330 stars, last pushed 3d ago), licensed Apache-2.0. It adds 119 tokens to every session and 9,228 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
