Teams Message Extractor C

Export Microsoft Teams chat messages, files, images, and emoji reactions to CSV or HTML. Auto-scrolls the full chat history for complete backup & archive — attachments bundled as a single ZIP.

Teams Message Extractor automatically scrolls through your full conversation history, from the very first message to the latest, and exports everything to a clean, structured CSV file or a self-contained HTML transcript. File attachments download as one ZIP archive instead of dozens of save prompts. Works with direct messages, group chats, and channels across all three Teams domains (teams.microsoft.com, teams.live.com, teams.cloud.microsoft).

What gets captured:

> Sender names & timestamps
> Full message content
> Emoji reactions (per message, with counts)
> File attachments, images, and their URLs
> Complete conversation threads

How it works:

1. Open any Teams conversation in your browser
2. Click the extension icon
