If you are managing the SharePoint online environment there pretty high chances that you would need to run the report on users who have access to the site / list / library and all sub-sites or sub-items. If you have a pretty complex structure of sites / lists and permissions you wouldn’t like to spend all your time by manually going and checking permission. Also, if you don’t have any reporting tools like ShareGate – PowerShell would be the best option here.

So, bellow is the PowerShell script to run 4 different permission reports on your SharePoint online site.



Report options:
– Quick check (Root-Site)
– Moderate (Object items and Inherited Permissions excluded)
– Moderate (Object items excluded)
– Full check (all sub-sites and items)



Pre-requisitions:- You need to have at least site collection admin permissions
– Run PowerShell ISE with admin privileges on your local machine
– Install pnp



Install-Module SharePointPnPPowerShellOnline


Here is the script to run

At the bottom you will find parameters on which report you would like to generate, you need to uncomment the according line.

Also, you need to provide your site URL and path to the folder very libs located and reports will be generated too.
$SiteURL =””



$ReportPath = “”



$LibsPath = “”



You don’t need to provide your credentials in the script as it uses web authentication.

The script will generate the excel file as the output in your specified ReportPath folder.

You can download the complete zip archive from here too.
