- Click Copy and paste it straight into a Slack message
- Send — bold, italics, lists, links, and code render correctly
Why Markdown Breaks in Slack
Slack does not use standard Markdown. It uses its own format, called mrkdwn, which looks similar but disagrees on the details. Bold text uses a single asterisk (*bold*), not two — so pasting **bold** into Slack shows stray asterisks instead of bold text. Italics use underscores (_italic_), strikethrough uses single tildes (~strike~), and links use the angle-bracket form <https://example.com|link text> instead of [link text](url).
Some Markdown features simply do not exist in Slack at all. There are no headings, so this converter turns ## Heading lines into bold text that reads like a section title. There are no tables either — Slack would show the raw pipes and dashes — so tables are rewritten as aligned monospace text inside a code block, which keeps the columns lined up and readable. Blockquotes, bullet lists, numbered lists, inline code, and fenced code blocks are kept, since Slack supports those natively.
Pasting ChatGPT or Claude answers into Slack
AI assistants respond in standard Markdown. Copy an answer from ChatGPT, Claude, or Gemini directly into Slack and you get a wall of **, ##, and broken links. Paste the answer here instead: the conversion runs instantly in your browser (nothing is uploaded), and the result is Slack-ready text you can drop into any channel, DM, or thread with formatting intact.
Frequently Asked Questions
Why does my Markdown look wrong when pasted into Slack?
Slack uses its own mrkdwn format: bold is a single asterisk, italics are underscores, links use <url|text> syntax, and headings do not exist. This tool rewrites standard Markdown into that format.
Can I convert ChatGPT or Claude output for Slack?
Yes — that is the most common use. Paste the AI response (which is Markdown) and copy the Slack-ready version with formatting that renders correctly in messages.
How are tables handled?
Slack has no table syntax, so tables are converted to aligned monospace text inside a code block, which keeps columns readable.
