What it does

处理独立电子表格文件,包括读取、问答、创建、编辑、修复、分析、清洗、重构、公式、格式、图表、数据验证、CSV/TSV 转换,以及复杂既有 XLSX/XLSM 模板的 OOXML 高保真修改、LibreOffice 无界面重算、公式缓存回填和 PDF 版面验证。用户提到 `.xlsx`、`.xlsm`、`.xltx`、`.xls`、`.csv`、`.tsv` 或本地表格/工作簿文件,并希望读取、修改或产出文件时使用。不要用于已打开或当前活动的 Excel 工作簿、当前选区、ChatGPT Excel 加载项或已连接 Excel 会话;这些实时操作交给 `spreadsheets:excel-live-control`。也不要用于 Google Sheets API,或主要交付物是 Word、PPT、网页、数据库管道而非表格的任务。

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

12工作簿中的说明、假设、解释或结论需要起草或改写时,按[文稿协作](../writing-router/references/collaborative-writing.md#主稿与交付)默认在 Markdown 中编辑文字,沿用已有确认与直接处理授权。修改已有工作簿时,仅整理待改文字及必要上下文,记录工作表和单元格位置;确认后回填最新工作簿的新版本,而不是把整张表转换成 Markdown 再重新导出。
13
14回填前核对目标位置、用户新增内容、样式和计算依赖,保留范围之外的值、公式、缓存、合并、图表、验证及打印设置。文字也可能参与公式匹配,是否重算按下文实际影响判断。显示不全时只调整必要的换行或行高。纯数据、公式和格式任务直接使用表格工具,不建立 Markdown 镜像;文件落位与排版不额外新增实质内容。

16## 文件存放与交付
17
18- 文件归属、正式位置和清理时机遵循已加载的共享全局规则。候选、临时脚本、预览和临时核验记录放在本任务过程目录;必要编辑源和资源依赖作为正式内容保留。
19- 沿用项目命名习惯;没有约定时用 内容主题_v01.扩展名,同名递增版本。生成并通过必要检查后,由智能体在最终回复前自动交付正式成果到约定的正式位置,复核交付文件的哈希、可打开性及必要依赖,并给出正式路径链接。需要用户挑选时,选定后再交付;不另设确认环节。
20- 使用工具的显式输出参数或将工作目录设到任务过程目录,保留工具所需内部结构;正文命令中的相对输出路径均以该目录为基准,技能脚本及输入路径使用绝对路径。不修改上游插件缓存。可编辑源、正式工程及原始数据保留其用途,不一律当作临时文件。
21- 普通任务结束后保留过程材料,用户显式触发 ChatNote(chat-notes)或明确要求清理后才进入可恢复清理;不自动清空过程目录。工具用于进程隔离、安全回滚的内部暂存清理不等于任务清场,仍遵守原有保护门。

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈100
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
18,300
on trigger
The instruction body and 20 supporting files, read only when the skill fires.
9.2%
of a 200k window
Ten skills this size would take about 92% of the window before you open a file.
050k100k150k200k context window

18.4k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

21 files, 288.9 kB on disk. Mostly text — the instructions the model reads — with 11 scripts in it that your client would run only if the instructions tell it to.

What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 11 scripts beside the text, so the bundle is 21 files you can review in full before installing.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Excel & Spreadsheet Automation · 18.4k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/excel-spreadsheet-automation/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/excel-spreadsheet-automation" ] && { [ ! -e .claude/skills/excel-spreadsheet-automation ] || { mv .claude/skills/excel-spreadsheet-automation "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/excel-spreadsheet-automation" .claude/skills/ && echo "Installed .claude/skills/excel-spreadsheet-automation"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add sanantonio021/excel-spreadsheet-automation

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/excel-spreadsheet-automation/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/excel-spreadsheet-automation/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/excel-spreadsheet-automation" ] && { [ ! -e ~/.claude/skills/excel-spreadsheet-automation ] || { mv ~/.claude/skills/excel-spreadsheet-automation "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/excel-spreadsheet-automation" ~/.claude/skills/ && echo "Installed ~/.claude/skills/excel-spreadsheet-automation" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/excel-spreadsheet-automation/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as xlsx in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, excel-spreadsheet-automation.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
