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.
