Overview

Extract Microsoft Teams chat messages and file attachments. Download as CSV, HTML, or a single ZIP archive. Export Microsoft Teams chat messages, files, images and emoji reactions to CSV or HTML. Scrolls the full chat history automatically for a complete backup and archive, with 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's new in 2.9.0: > New: channel (Posts) extraction. Threaded channel conversations export with every nested reply, subject line and thread structure included. > New Markdown export, ideal for pasting into notes, wikis or AI tools. > CSV export now opens correctly in Excel. Accented and international characters (é, ã, ü, ç) are no longer garbled. > Pasted images and screenshots are now captured reliably, including on the new teams.cloud.microsoft layout where many were previously missed. > Screenshots are embedded directly in the HTML transcript, so images appear in the export itself rather than as links. > Attachments save as the exact original file at original quality, with no recompression. 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.
