Output all groups and permissions throughout a SharePoint Online farm?

Question

After a large migration I'd like to review all SharePoint groups and permissions via an algorithm but before I do I need to export them.

Is there some powershell I can run to output this throughout the farm (including cases where I have multiple nested sites)?

Answer 1

Please check if below Powershell command helps you:

Get-SPOSite | ForEach-Object {Get-SPOUser -Site $_.Url} | Format-Table -Wrap -AutoSize | Out-File c:\UsersReport.txt -Force -Width 360 -Append
