Feishu Md Exporter

Feishu Markdown Exporter

Use this skill to export Feishu/Lark documents to Markdown. It supports the two common personal workflows:

1. Export one Feishu/Lark document URL to .md.
2. Recursively export a Feishu/Lark Drive folder tree to local .md files.

The implementation uses official Feishu Open Platform APIs:

• OAuth user authorization to obtain user_access_token.
• Drive folder listing API for folder recursion.
• Docx document metadata and blocks APIs to read document content.
• Local conversion from Feishu block JSON to Markdown.

It does not crack private documents or bypass view permissions. The user must have view access, and the app must have the required API scopes. It can still export Markdown when the UI disables copy/export, because reading document blocks and official file export are separate permission surfaces.

Script

Run the bundled script:

python /Users/weijian/.agents/skills/feishu-md-exporter/scripts/export_feishu_md.py <feishu-url> --output <output-dir>

For a single document:

python /Users/weijian/.agents/skills/feishu-md-exporter/scripts/export_feishu_md.py \
  "https://example.feishu.cn/docx/xxxxx" \
  --output ./feishu_md_exports

For a folder:

python /Users/weijian/.agents/skills/feishu-md-exporter/scripts/export_feishu_md.py \
  "https://example.feishu.cn/drive/folder/xxxxx" \
  --output ./feishu_md_exports

Credentials

Prefer environment variables:

export FEISHU_APP_ID="cli_xxx"
export FEISHU_APP_SECRET="xxx"

Or pass them explicitly:

python scripts/export_feishu_md.py <url> --app-id cli_xxx --app-secret xxx

Or store them in:

~/.feishu-md-exporter/config.json

Format:

{
  "app_id": "cli_xxx",
  "app_secret": "xxx"
}

The OAuth token cache is stored at:

~/.feishu-md-exporter/token_cache.json

Required Feishu App Setup

In the Feishu/Lark developer console:

1. Add redirect URL exactly:

http://localhost:9876/callback

2. Enable and publish the relevant scopes:

docx:document:readonly
wiki:wiki:readonly
drive:drive:readonly
drive:file:readonly

drive:export:readonly is not required for Markdown block export, but it is harmless if already enabled.

3. On first run, complete the OAuth page in the browser.

Workflow

1. Identify whether the URL is a single document, wiki node, or Drive folder.
2. If credentials are missing, ask for app_id and app_secret, or ask the user to create ~/.feishu-md-exporter/config.json.
3. Run the script with a clear output directory.
4. If OAuth opens in the browser, tell the user to approve it. If the page says redirect URL error, tell them to add http://localhost:9876/callback under Security Settings -> Redirect URL.
5. After export, report:
   • Output directory or file path.
   • Number of Markdown files exported.
   • Any failed or skipped items.

Common Errors

• redirect URL error / code 20029: the app did not configure http://localhost:9876/callback as a redirect URL.
• no permission / 403: the user or app lacks view/API permission for the document or folder.
• scope or authorization error: add and publish the required scopes, then delete ~/.feishu-md-exporter/token_cache.json and retry.
• Folder export returns no docs: verify the URL is a Drive folder URL and the user has view access to the folder contents.

Output Behavior

• Folder export preserves the Feishu folder tree locally.
• Unsupported path characters such as / are replaced with _.
• Duplicate names receive suffixes like _2.
• Images and files may be represented as placeholders if the Blocks API returns only tokens and the script does not download binary assets.

Keep the user-facing response short: say whether it worked, where the files are, and the counts.
