将任意文件（PDF、Word、Excel、PPT、图片、音频、网页等）转换为 Markdown
README (SKILL.md)
All to Markdown
基于 Microsoft MarkItDown，将任意格式的文件或 URL 转换为 Markdown，便于 LLM 分析和处理。
支持格式
| 类型 | 格式 |
|---|---|
| 文档 | PDF、DOCX、PPTX、XLSX、XLS、EPUB、MSG |
| 数据 | CSV、JSON、XML |
| 图片 | JPG、PNG 等（含 EXIF 元数据，可选 OCR） |
| 音频 | WAV、MP3（含语音转录，需 OpenAI Key） |
| 网页 | HTML、YouTube URL（含字幕提取） |
| 压缩 | ZIP（逐文件转换） |
前置要求
安装 markitdown：
pip install 'markitdown[all]'
给 AI 的使用说明
当用户需要将文件或 URL 转换为 Markdown 时，使用以下命令：
scripts/run.sh \x3C文件路径或URL>
可选标志：
-o \x3C输出文件>— 保存到文件--use-plugins— 启用插件（如 markitdown-ocr）
重要原则：
- 转换结果直接输出到 stdout，可供 AI 直接读取分析
- 文件路径使用用户提供的实际路径，不要假设
- 转换大型文件时提前告知用户可能需要较长时间
使用示例
示例 1：转换 PDF
用户：帮我把这个 PDF 转成 Markdown，以便我分析内容
AI 执行：
scripts/run.sh /path/to/document.pdf
示例 2：转换并保存
用户：把这个 Excel 转成 Markdown 文件保存
AI 执行：
scripts/run.sh /path/to/data.xlsx -o output.md
示例 3：转换网页
用户：把这篇文章转成 Markdown
AI 执行：
scripts/run.sh https://example.com/article.html
示例 4：提取 YouTube 字幕
用户：把这个 YouTube 视频的内容提取出来
AI 执行：
scripts/run.sh https://www.youtube.com/watch?v=xxx
可选 AI 增强功能
设置 OPENAI_API_KEY 后，markitdown 可对图片生成 AI 描述：
OPENAI_API_KEY=sk-xxx scripts/run.sh image.jpg
安全说明
- 仅在本地执行文件转换，不发送文件内容到远程服务
- 转换 URL 时会访问对应网络地址
- 启用 LLM 功能时，图片内容会发送到 OpenAI API
Usage Guidance
This skill is a thin wrapper around the community markitdown tool and appears internally consistent. Before installing: (1) review and install markitdown from PyPI in a virtualenv (pip install 'markitdown[all]') rather than running untrusted installers; (2) be aware that converting a URL causes the tool to fetch remote content and enabling OPENAI_API_KEY will send image/OCR content to OpenAI — do not pass sensitive documents or secrets if you enable that feature; (3) consider inspecting markitdown's code or its installed plugins if you need higher assurance; and (4) note the small metadata mismatch about the required binary (markitdown) — ensure that CLI is present on the system before invoking the skill.
Capability Analysis
Type: OpenClaw Skill
Name: all-to-markdown
Version: 1.0.0
The skill is a legitimate wrapper for Microsoft's 'markitdown' tool, designed to convert various file formats and URLs into Markdown. The shell script (scripts/run.sh) and configuration (config.json) correctly implement the stated functionality without any signs of malicious intent, data exfiltration, or obfuscation. It follows standard practices for handling user-provided inputs and clearly documents its dependency on the 'markitdown' Python package.
Capability Assessment
Purpose & Capability
The skill's name/description, SKILL.md, config.json, and run.sh consistently describe a wrapper around the markitdown CLI to convert files/URLs to Markdown. Minor inconsistency: top-level registry metadata listed no required binaries, while config.json and scripts/run.sh require the markitdown CLI (installed via pip). This is explainable (packaging metadata omission) but worth noting.
Instruction Scope
SKILL.md instructs the agent to run scripts/run.sh with a user-provided path or URL and to pass through options to markitdown; the runtime script only checks for markitdown and execs it. Instructions limit network access to fetching provided URLs/YouTube and clearly mark OPENAI_API_KEY as optional for AI-enhanced image/OCR features.
Install Mechanism
No automatic install spec in the skill bundle; SKILL.md and config.json recommend installing markitdown via pip (pip install 'markitdown[all]'). This is a standard public-package install path and the bundle does not download arbitrary archives or run remote installers.
Credentials
No required environment variables. OPENAI_API_KEY is declared optional and used only for AI/image/OCR enhancements as documented — this is proportional and expected. The skill does not request unrelated credentials or access.
Persistence & Privilege
The skill does not request always:true, does not modify other skills or system-wide config, and is user-invocable only. It executes markitdown at runtime and does not persist elevated privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install all-to-markdown - After installation, invoke the skill by name or use
/all-to-markdown - Provide required inputs per the skill's parameter spec and get structured output
