What it does
XLSX is an agent skill from nexus-research-lab/nexus. 只要电子表格文件（.xlsx、.xlsm、旧版 .xls、.csv、.tsv）是任务的主要输入或输出，或者需要 被打开、读取、创建、修改，就使用本 Skill。也适用于公式、格式、图表、数据清洗和表格格式转换。 不用于既不读取也不产出表格文件的一般数据分析、数据库流程、独立脚本或普通文档制作。
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts (for example `scripts/read_spreadsheet.py` and `tests/test_read_spreadsheet.py`).
It sits in Documents & Office, covering Excel spreadsheets and CSV and tabular files. It works with Microsoft Excel, Python, LibreOffice and openpyxl. The repository describes itself as: Multi-agent collaboration platform for persistent, proactive AI agents across rooms, workspaces, skills, and external services. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Excel spreadsheets
- Tasks that involve CSV and tabular files
Example prompts
- “/xlsx”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- 含公式时先在单独目录用 LibreOffice 重算，检查转换结果后再作为最终文件，不能直接覆盖未验证的源文件。
- 用读取脚本回读关键范围，确认公式仍存在、缓存值已更新，并扫描 #REF!、#DIV/0!、
- 用 LibreOffice 导出 PDF 或工作表预览，检查每张非空工作表的标题、表头、关键数字、图表、分页和打印区域。
- 缺少 LibreOffice 时可以继续不依赖重算的读取；含公式的写任务必须说明结果尚未由表格引擎重算。
- 最终只交付用户要求的 XLSX/XLSM/CSV/TSV，不附带构建脚本和预览文件。
What it can do on your machine
Read from SKILL.md and the folder at commit 67f54e7. 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 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 501 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 82 words of instructions outside code blocks.
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 nexus-research-lab/nexus at commit 67f54e7, republished under its Apache-2.0 licence (© nexus-research-lab). 82 words, ~501 tokens.

Excel 工作簿
| 任务 | 路径 |
|---|---|
| 快速读取 XLSX | 运行自带读取脚本，保留工作表、行列和公式信息 |
| 读取 CSV/TSV | 用 Python csv 或通用文本工具；保留原始字段类型约束 |
| 新建或编辑工作簿 | 用 openpyxl 处理公式、格式、表格和图表 |
| 大批量数据清洗 | 标准库足够时直接使用；确有需要再用 pandas |
旧版 .xls | 用 LibreOffice 转为 .xlsx，保留原件 |
工作契约
- 只读问题不保存、重算或导出工作簿。
- 写操作默认另存新文件；模板和既有格式优先于默认样式。
- 先直接使用当前环境。
import openpyxl失败且任务需要写文件时，取得用户同意后在隔离环境安装${CLAUDE_SKILL_DIR}/requirements.txt，不要静默修改系统 Python。
读取
python3 "${CLAUDE_SKILL_DIR}/scripts/read_spreadsheet.py" "<input.xlsx>"
python3 "${CLAUDE_SKILL_DIR}/scripts/read_spreadsheet.py" "<input.xlsx>" --sheet "<sheet-name>" --max-rows 1000 --max-columns 100
python3 "${CLAUDE_SKILL_DIR}/scripts/read_spreadsheet.py" "<input.xlsx>" --output "<new-output.md>"脚本同时显示公式文本和文件内缓存值。关键结论要定位到工作表与单元格，并沿公式引用核对输入； 缓存可能过期，不能把它当成刚刚重算的结果。
创建与编辑
在 workspace 或临时目录写一个可重复运行的短 Python 脚本，再用 openpyxl 输出文件。
- 数值、日期、百分比和货币写成真实类型，格式代码只负责显示；ID、邮编等标识符才写文本。
- 派生结果使用可读公式并引用输入单元格，不把 Python 计算值或魔法数字写死在计算区。
- 跨表引用始终给工作表名加单引号，例如
='Assumptions'!B5；正确使用绝对和相对引用。 - 读取公式与缓存值时分别打开两次。绝不能保存以
data_only=True打开的工作簿，否则公式会丢失。 - 编辑时延续相邻格式、公式模式、条件格式、表格和图表范围；不要对成熟模板做全表重排。
.xlsm使用keep_vba=True，并保持宏格式输出。外部链接、透视表、切片器和高级图表可能在往返保存时变化， 只修改必要区域并明确验证范围。
完成条件
- 含公式时先在单独目录用 LibreOffice 重算，检查转换结果后再作为最终文件，不能直接覆盖未验证的源文件。
- 用读取脚本回读关键范围，确认公式仍存在、缓存值已更新，并扫描
#REF!、#DIV/0!、#VALUE!、#NAME?、#N/A等错误。 - 用 LibreOffice 导出 PDF 或工作表预览，检查每张非空工作表的标题、表头、关键数字、图表、分页和打印区域。
- 缺少 LibreOffice 时可以继续不依赖重算的读取；含公式的写任务必须说明结果尚未由表格引擎重算。
- 最终只交付用户要求的 XLSX/XLSM/CSV/TSV，不附带构建脚本和预览文件。

What does XLSX do?
只要电子表格文件（.xlsx、.xlsm、旧版 .xls、.csv、.tsv）是任务的主要输入或输出，或者需要 被打开、读取、创建、修改，就使用本 Skill。也适用于公式、格式、图表、数据清洗和表格格式转换。. XLSX is an agent skill from nexus-research-lab/nexus.
When should I use XLSX?
XLSX fits situations like: tasks that involve Excel spreadsheets; tasks that involve CSV and tabular files.
How do I install XLSX in Claude Code?
Run `npx skills add nexus-research-lab/nexus --skill xlsx -a claude-code`. Or copy the skill folder (skills/xlsx in nexus-research-lab/nexus) 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 nexus-research-lab/nexus --skill xlsx -a codex`. Or copy the skill folder (skills/xlsx in nexus-research-lab/nexus) 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 nexus-research-lab/nexus --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 (python3). Our summary lists: Python 3.
Does XLSX access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. 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 Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does XLSX use?
About 501 tokens (SKILL.md is roughly 2k 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: Spreadsheet (davila7/claude-code-templates, 33k stars), Openai Spreadsheet (trailofbits/skills-curated, 513 stars), Excel Workbook Editor (HKUDS/DeepTutor, 41k stars) and BiSheng XLSX Workbook Builder (dataelement/bisheng, 12k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains XLSX?
nexus-research-lab (a GitHub organization) maintains it in nexus-research-lab/nexus, which has 151 GitHub stars. The repository holds 17 skills in this directory. The repository was last updated on October 10, 2026.
