Feishu Md2blocks

Insert rich Markdown content (including tables) into Feishu documents. Use when feishu_doc write/append fails with tables, or when inserting complex formatted content (tables, code blocks, nested lists) into an existing document at a specific position.

Feishu Markdown to Blocks

Insert Markdown content—including tables—into Feishu documents via the block convert + descendant API.

When to Use

• feishu_doc write replaces the entire document; use this to insert content at a position
• feishu_doc create_table_with_values has limitations for larger tables
• You need to insert tables, code blocks, or complex nested content into an existing doc

Usage

bash

# Insert from file (appends to document end)
python3 <skill_dir>/scripts/md2blocks.py <doc_token> content.md

# Insert from stdin
echo "| A | B |\n|---|---|\n| 1 | 2 |" | python3 <skill_dir>/scripts/md2blocks.py <doc_token> -

# Insert after a specific block
python3 <skill_dir>/scripts/md2blocks.py <doc_token> content.md --after <block_id>

# Replace all content
python3 <skill_dir>/scripts/md2blocks.py <doc_token> content.md --replace

How It Works

1. Calls POST /docx/v1/documents/blocks/convert to convert Markdown → block structures
2. Removes merge_info from table blocks (read-only field that causes insertion errors)
3. Calls POST /docx/v1/documents/{doc}/blocks/{parent}/descendant to insert blocks

The descendant API handles nested structures (tables with cells containing text) that the simpler /children API cannot.

Position Control

The --after <block_id> option inserts content right after the specified block. The script finds the block's index automatically.

Key detail: The /descendant API's index parameter must be in the request body, not as a URL query parameter. Passing ?index=N in the URL is silently ignored (content appends to end). The script handles this correctly.

Supported Markdown

Text, headings (h1-h9), bullet lists, ordered lists, code blocks, quotes, tables, todo items, dividers.

Limitations

• Images in Markdown are not automatically uploaded; they require separate upload + patch steps
• Max 1000 blocks per insert call; split large documents if needed
• Requires docx:document.block:convert permission on the Feishu app
• Document edit rate limit: 3 ops/sec per document
