MS Teams has a nice feature that’ll allow the meeting organiser to download an attendance report. You’ll get a .csv file with information about the meeting and the participants. There’s a full name, join and leave time, duration, email address, and role for each of them. The .csv report is easy to read if you open it in Excel as Excel will format it in an easy to read way. But without Excel it’s not so pretty. And if you want to process it automatically, you’ll need to process the original file in its format.
