I was recently asked by a client to look for a PowerShell script that would export the permissions for all of the files and folders within each of their site collection so they can perform a thorough audit and as common as such a request seemed to me, I had much difficulty when I searched through the internet for such a script. Since I did not have any luck finding one that actually worked, I reached out to one of our SharePoint resources for help and he eventually provided one that was able to execute and export the permissions to a CSV file. I am unsure as to where the script is from so I’d like to apologize for not crediting the author but I hope this will provide anyone who may be looking for such a script as I did.
The generated report will look as such:
The following PowerShell script runs against per site collection so you will need to run it multiple times against as many sites as required as well as grant yourself administrative permissions to the site collection:
The script only requires two lines to be adjusted accordingly:
#region ***Parameters***
$SiteURL=”https://contoso.sharepoint.com/”
$ReportFile=”C:tempSitePermissionRepor.csv”
#endregion
Other sites will require the path to be adjusted as such:
$SiteURL=”https://contoso.sharepoint.com/sites/FinanceSite”
The following is the PowerShell script:

Great work Terence and thanks for sharing.
I have used this script and adapted it to add a new column to filter by Web URL and also to run over every site collection.
Thanks
