slack-xport

slack-xport turns a Slack search result page into LLM-ready context with one click.

Pasting Slack threads into ChatGPT, Claude, or any LLM as context is common — but copying messages by hand is tedious, loses formatting, and breaks across pagination. slack-xport automates the entire flow so you can focus on the prompt instead of the copying.

WHAT IT DOES
- Walks every page of a Slack search result automatically
- Expands "Show more" truncations, including those nested inside quoted blocks
- Preserves Markdown formatting: bold, italic, strikethrough, inline code, code blocks, bullet/ordered lists, links, blockquotes
- Captures file/image attachments as Markdown image syntax
- Strips Slack tracking parameters from attachment URLs to keep token count low
- Outputs YAML with block scalars, so multi-line messages stay readable
- Auto-copies the result to your clipboard

HOW TO USE
1. Open Slack at app.slack.com and run a message search
2. Click the slack-xport toolbar icon
3. Click "Export & Copy"

The popup shows a status pill so it is clear when the extension is ready, when it is collecting messages, and when the result has been copied. If the result is over 1 MB you will be asked to confirm before copying. A "Download as YAML file" link is available as a fallback.

PRIVACY
Everything runs locally in your browser. No data is sent to any external server. No analytics, no tracking. Required permissions are limited to activeTab and host permission for https://app.slack.com/* — the minimum needed to read the search result DOM and copy text to your clipboard.

ACKNOWLEDGEMENTS
Built on top of the DOM scraping logic from xshoji/slack-search-result-exporter (MIT-licensed bookmarklet), extended into a packaged extension with richer formatting and an LLM-oriented output.
