Document conversion assistant that automatically converts documents to Markdown (MD), saving output to the same directory as the source file. Designed to help intelligent agents read and process document content in various formats.

Quick Start

bash

# Convert document (auto-polls for 60s, downloads if complete, returns doc ID if timeout)
node scripts/doc2markdown.js convert <file_path>     # Downloads MD package
node scripts/doc2markdown.js convert <file_path> --md  # Downloads single MD file

# Check status and download (for documents that exceeded timeout)
node scripts/doc2markdown.js check <doc_id> <original_file_path>     # Downloads MD package
node scripts/doc2markdown.js check <doc_id> <original_file_path> --md  # Downloads single MD file

Capabilities

• Supported formats: docx, doc, pdf, ppt, pptx, xls, xlsx, jpg, jpeg, png, ceb, teb, caj, odt, ofd, cebx, odp, ott, wps, ods, et, dps, epub, chm, sdc, sdd, sdw, mobi, etc.
• Preserves document structure, tables, and images
• API Key is optional, zero external dependencies. Without an API Key doc2markdown works exactly as before (anonymous upload); with one configured, the convert request is authenticated. See API Key (Optional)
• Downloaded ZIP files are extracted to {doc_id}_{filename}/ under the source file's parent directory; single MD files are saved directly there

When to Use

• User requests to "read", "extract", "convert", or "view" a document
• User provides a document path and asks about its content
• User needs to summarize or analyze a document
• User needs to convert document content to Markdown package

Download Modes

This tool supports two download modes:

• --md mode: Downloads a single merged MD file to the source file's parent directory. Images are not included
• MD package: Downloads and extracts a ZIP package to {doc_id}_{filename}/ in the source file's parent directory. Includes image files and tables, tables are rendered in HTML format

Choosing the Right Mode

User Intent	Example Phrases	Mode to Use
Read / view / analyze a document	"read this file", "what's in this doc", "summarize this PDF"	--md (single MD file)
Explicitly convert to MD	"convert to MD", "export as markdown", "转成MD"	MD package (default, no --md); use --md only if user specifically asks for a single file

Workflow

convert — Convert Document

1. Invoke file parsing service
2. Auto-poll conversion status (up to 60 seconds)
3. Completes within 60s → Auto-download to source file directory
4. Exceeds 60s → Return doc ID for subsequent check query

check — Query and Download

1. Provide the previously returned doc ID
2. Download if complete, otherwise continue polling for 60 seconds
3. Prompt to retry later if still not complete

API Key (Optional)

An API Key is optional — without one, doc2markdown works normally as before.

Configuring an API Key

Source	Location
Environment variable	DOCCHAIN_SKILLS_API_KEY
Skill config	doc2markdown/scripts/config.json (field docchain_api_key)

With an API Key configured

Conversions are processed with priority (fast lane).
