# markdown-to-mrkdwn — A library to convert Markdown to Slack's mrkdwn format

License: permissive · Maintenance: active · Downloads: 3.0M/mo

## What it is and what it does

markdown_to_mrkdwn is a lightweight converter that transforms standard Markdown syntax into Slack's mrkdwn format. It handles the full range of common Markdown elements—headings, bold and italic text, ordered and unordered lists, task lists, tables, code blocks, blockquotes, links, and horizontal rules—and maps them to their Slack equivalents. The library has no external dependencies and is designed to preserve code block contents without conversion, making it safe for technical documentation and code examples.

You use it by instantiating a SlackMarkdownConverter, then calling its convert() method on a Markdown string to get back properly formatted mrkdwn ready to post to Slack. The package also exposes a plugin system allowing you to register custom line-based or regex-based transformations before or after the core conversion, giving you flexibility to extend or customize the output for specific use cases.

Use it for:

- Automatically format Markdown documentation or release notes into Slack messages without manual reformatting.
- Convert user-generated Markdown content (e.g., from a web form or editor) into Slack-compatible format before posting.
- Build Slack bots or integrations that accept Markdown input and deliver properly formatted Slack messages.
- Extend the converter with custom plugins to mask sensitive data (e.g., email addresses) or apply domain-specific formatting rules.
- Preserve code snippets and technical content when migrating documentation from Markdown-based systems into Slack.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Converts standard Markdown to Slack's mrkdwn format, handling headings, text formatting, lists, tables, code blocks, links, and other common Markdown elements for use in Slack messages.

Yes. The package solves a real problem (Markdown-to-Slack conversion) with zero dependencies, active maintenance, no known vulnerabilities, and a permissive MIT license. It is straightforward to install and use. Install it if you need to programmatically format Markdown for Slack; skip it only if you have no Slack integration needs.

## Install

pip install markdown-to-mrkdwn
uv add markdown-to-mrkdwn
poetry add markdown-to-mrkdwn
