Copy a Slack search result to your clipboard as a single YAML document, ready to paste into an LLM prompt.
Pasting Slack threads into ChatGPT, Claude, or any LLM is common — but copying messages by hand loses formatting and breaks across pagination. slack-xport automates the whole flow so you can focus on the prompt instead of the copying.
- Walks every page of a Slack search automatically
- Expands "Show more" truncations (including those inside quoted blocks)
- Preserves Markdown formatting: bold, italic, code, code blocks, lists, links, images
- Captures file/image attachments as Markdown image syntax
- Copies the result to your clipboard with one click
- Run a message search at
app.slack.com - Click the slack-xport toolbar icon
- Click Export & Copy
The extension navigates to page 1 if needed, walks every page, expands truncations, and auto-copies the YAML to your clipboard. If the result exceeds 1 MB you are asked to confirm before copying. A "Download as YAML file" link is available as a fallback.

A multi-line message.
Line breaks, **bold**, `inline code`, and code blocks
are all preserved.

Single-line messages stay readable.
YAML's | block scalar handles multi-line content cleanly. Quotes are omitted when not strictly required, keeping token count low.
