Zoom attendance report vs live roster: what the CSV doesn't tell you
By JP Copeland, Data On The Spot · Last updated 28 September 2026.
Short answer: Zoom's usage report is a log of connections, not an attendance record. It tells you which display names joined and left and for how long, and only after the meeting ends. It does not know your membership, cannot separate voters from guests, does not count proxies, and cannot show quorum at the moment a vote was taken. A live roster match fills that gap during the meeting.
What the Zoom usage report gives you
In the Zoom web portal, Reports → Usage → click the participant count for a meeting → Export. You get a CSV with display name, email if the person was signed in, join time, leave time and duration. If someone dropped and rejoined they appear more than once unless you tick "show unique users". The report is only available to the person who hosted the meeting, and only after the meeting.
What it does not give you
| You need | Zoom usage report | RollCall Live |
|---|---|---|
| Who is on the call right now | No, after the meeting only | Yes, live board |
| Which participants are voting members | No | Yes, matched to your roster (Voter / Observer / Guest) |
| Who is absent | No | Yes |
| Unmatched names flagged for review | No | Yes |
| Proxies and advance ballots in the count | No | Yes |
| Quorum status at the moment of a vote | Reconstruct by hand from timestamps | Freeze the roll |
| Attendance log for the minutes | Raw CSV | Attendance log + meeting pack zip |
When the usage report is enough
Training sessions, webinars, classes, and any meeting where "who showed up and for how long" is the whole question. Export the CSV and file it.
When it is not
Board, union, association, HOA, condo and co-op meetings where decisions depend on who is present. The chair needs the count before the vote, not a spreadsheet the next morning, and the record needs to show members, not display names.
Using both
Plenty of organizations keep the Zoom CSV as the raw log and use the RollCall attendance log and frozen rolls as the attendance record for the minutes. RollCall keeps records for 30 days, so download the meeting pack after each meeting.
