Export SharePoint sites to CSV — site inventory for migration

planning and tenant management.

Exports all SharePoint Online sites with URL, title, template, owner, storage usage/quota, compatibility level, hub association, and dates. Storage usage percentage is a derived column — compute it in your spreadsheet (StorageUsageCurrent / StorageQuota * 100).

Essential for: - SharePoint migration planning (source inventory) - Tenant consolidation or split - Storage governance and legacy site identification

Permissions

Requires an app with Sites.FullControl.All (or a SharePoint / Global admin account) on the admin site.
