MS Copilot → Markdown 作成者: ITSC IT Systems Consulting GmbH

Creates a GFM-style Markdown file from a Copilot chat.

The export is triggered either by clicking the extension icon or via the Copilot → Markdown ... entry in the context menu.

The extension currently supports the following Copilot versions:

• m365 Copilot: https://m365.cloud.microsoft
• MS Copilot: https://copilot.microsoft.com

Unlike similar extensions, no external services are used; conversion takes place entirely locally on your computer - your data remains 100% with you.

Features

With a few exceptions (see below), the generated Markdown code preserves all content and formatting from the chat:

• Headings
• Lists and bulleted lists, with structure
• Quotes
• Tables
• Inline code and code blocks
• Links
• Images. This includes embedded images; for each image, the image file is automatically downloaded before the Markdown file is downloaded. Warning: Do not change the names of the image files, otherwise the Markdown code will not be able to find them!

Limitations

What is not exported:

• Source references in the “new” (July 2026) layout of m365-Copilot consist of a button that displays the URLs in the sidebar via JavaScript. The extension cannot parse this, so the source references are lost.
• Horizontal rules (hr) before headings are intentionally removed because they are typographically incorrect and disrupt the layout.

Please note

1. For longer chats, the Copilot web interface sometimes loads only a portion of the chat into the browser; when you scroll, the now-visible parts are reloaded, but the parts that are no longer visible are removed from the browser’s memory (DOM). This extension can only export the parts that are currently loaded. You may therefore need to perform multiple exports for a single chat.
2. Microsoft is constantly changing the structure of the Copilot page. Although I’ve tried to make the export as independent as possible from the structure, the CSS classes used, etc., it’s possible that after a change by Microsoft, the extension may no longer format some content correctly or may not find it at all.
   In such cases, please create a ticket as described below; I will do my best to update the extension as soon as possible.
3. If you are a programmer yourself, you can customize the source code on your own (see the section "Source Code Availability"; this is usually limited to adjusting CSS selectors in the CONFIG section. I would appreciate it if you could send me the changes in a ticket (e.g., as a diff); I can then incorporate them into the extension packages available in the shops.

Issues and Feature Requests

• If you encounter any issues or have feature requests, please open a ticket in the GitHub project copilot2markdown:
  https://github.com/ITSC-GmbH/copilot2markdown
• Please check first to see if another ticket on the same topic already exists.
• Be sure to specify whether m365 or MS Copilot is affected; these two are based on completely different page structures.
• For bugs, describe how the issue can be reproduced; screenshots and the faulty Markdown export are helpful.
