Slack Sweeper

Deactivate Slack users from a CSV using your current admin session.

Slack Sweeper helps Slack Admins bulk deactivate users from a CSV file using their current Slack admin session. It is designed for Slack Admins on Premium plans who need a bulk deactivation workflow when the Slack API or web UI does not provide the function they need. If your Slack plan already includes built-in bulk deactivation, use Slack’s native feature instead. How it works: - Open your Slack Admin page - Open this extension - Upload a CSV file with one Slack user ID per line - Run the deactivation process from the extension popup Recommended workflow: - Export the full member list from Slack Admin (People > Member) - Filter the list in your spreadsheet tool - Keep only the user ID column - Save/export as CSV - Use that CSV in Slack Sweeper This extension is intended for admin cleanup operations and account lifecycle management in Slack workspaces.
