About this skill

XLSX is a skill in axoviq-ai/synthadoc (1.6k stars). Its SKILL.md is about 267 tokens, with 3 other files in the folder (scripts). Licence: AGPL-3.0-or-later.

What it can do on your machine

Read from SKILL.md and the folder at commit 90d0db7. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- pip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

XLSX loads about 267 tokens when it runs. Until then it costs about 11 tokens; SKILL.md has 54 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~11
When it runs · the whole SKILL.md, loaded when a task matches: ~267

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

The full file from axoviq-ai/synthadoc at commit 90d0db7, republished under its AGPL-3.0-or-later licence (© axoviq-ai). 54 words, ~267 tokens.

Setup

bash

pip install openpyxl

.csv files use only the Python standard library — no additional install required.

Standalone usage

python

import asyncio
from synthadoc.skills.xlsx.scripts.main import XlsxSkill

skill = XlsxSkill()

async def main():
    result = await skill.extract("/path/to/data.xlsx")
    print(result.text)      # all rows as comma-separated text
    print(result.metadata)  # {"rows": N, "sheets": N}  (xlsx only)

asyncio.run(main())

When this skill is used

Source path ends with .xlsx or .csv
User intent contains: spreadsheet, excel, csv

Questions about XLSX

How do I install XLSX in Claude Code?

Run `npx skills add axoviq-ai/synthadoc --skill xlsx -a claude-code`. Or copy the skill folder (synthadoc/skills/xlsx in axoviq-ai/synthadoc) into .claude/skills/xlsx in your project. Claude Code loads it when a task matches its description.

How do I install XLSX in Codex?

Run `npx skills add axoviq-ai/synthadoc --skill xlsx -a codex`. Or copy the skill folder (synthadoc/skills/xlsx in axoviq-ai/synthadoc) into .agents/skills/xlsx in your project. Codex loads it when a task matches its description.

Can I use XLSX in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add axoviq-ai/synthadoc --skill xlsx -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/xlsx, .gemini/skills/xlsx, .github/skills/xlsx and .opencode/skills/xlsx in your project.

What does XLSX need to run?

Going by SKILL.md and its folder, XLSX needs Python for the scripts in its folder and the command-line tools its instructions call (pip).

Does XLSX access the network?

SKILL.md contains no URLs. Its commands use pip, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is XLSX safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does XLSX use?

XLSX is published under the AGPL-3.0-or-later licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does XLSX use?

About 267 tokens (SKILL.md is roughly 1.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to XLSX?

Skills that share tags, products or a category with XLSX: File Intel (earlyaidopters/second-brain, 194 stars), Data Table Manager (n8n-io/n8n, 207k stars), Instrument Data To Allotrope (aws-samples/amazon-bedrock-agents-healthcare-lifesciences, 274 stars) and Markit (shift-labs-ai/markit, 1.3k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains XLSX?

axoviq-ai (a GitHub organization) maintains it in axoviq-ai/synthadoc, which has 1,578 GitHub stars. The repository holds 9 skills in this directory. The repository was last updated on October 10, 2026.

Source: axoviq-ai/synthadoc on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
