Which file formats are supported?

The document lists 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, and mobi, plus other formats described as “etc.”

Where are the conversion results saved?

`--md` saves a single merged MD file in the source file’s parent directory. The default mode downloads a ZIP package and extracts it to `{doc_id}_{filename}/` there; the package includes images and HTML-rendered tables, while `--md` does not include images.

What happens if conversion takes longer than 60 seconds?

`convert` polls for up to 60 seconds and returns a document ID if it times out. Use `check` with that ID to poll for another 60 seconds; if conversion is still incomplete, the tool asks you to retry later.

Design & media

Doc2Markdown

Try it

Convert supported documents into Markdown for agent-side reading, with local output and optional image-preserving packages.

What it does

Doc2Markdown converts supported document files to Markdown and saves the result beside the source. It supports `--md` for one merged file without images, or a ZIP package with extracted images and HTML-rendered tables. Conversion polls for up to 60 seconds, then provides a document ID for a later check if needed. Files are uploaded to the docchain cloud service over HTTPS; no API key, account, or external dependency is required.

When to use it

Reading or analyzing PDF or Office documents
Converting a document to one Markdown file
Preserving images and tables in a package
Retrying a conversion that exceeds 60 seconds

The skill document

doc2markdown

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

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

# Check status and download (for documents that exceeded timeout)
node scripts/doc2markdown.js check       # Downloads MD package
node scripts/doc2markdown.js check   --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
No API Key or account required, zero external dependencies
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

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

check — Query and Download

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

Data & Privacy

convert uploads files to the docchain cloud service (lab.hjcloud.com) for parsing. Results are returned as a ZIP archive and extracted locally.
All transfers use HTTPS encryption.
Users should ensure that documents do not contain sensitive or confidential information unless they have verified the service's data handling practices.
Service endpoint: https://lab.hjcloud.com/llmdoc
