Add users to the Associated SharePoint Groups of a site from a CSV File

Author: Arjun Menon

Script Details

This is a script which adds multiple users to associated SharePoint groups (Owners, Members, Visitors) of a site from a CSV file.

Typical use case of the script will be a migration scenario where the contents are migrated, while the permissions are not migrated. In that case you will have a list of users and its equivalent permission level of the source system. The script sample will read the source permission details from a CSV file and will add the users to the associated SharePoint groups of a site

File Format

Below is an example of the format needed for your .csv file:

Username,PermissionLevel
adelev@contoso.com,Read
alexw@contoso.com,Owner
alland@contoso.com,Member
christiec@contoso.com,Member

Permission Level Mapping

Permission Level mapping assumptions are given below

Permission Level Equivalent SharePoint Group Details
Read Visitors User will be added to the associated Visitors group of the site
Owner Owners User will be added to the associated Owners group of the site
Member Member User will be added to the associated Owners group of the site

Complete Script

#Check the M365 login status for CLI
$LoginStatus = m365 status
if($LoginStatus -Match "Logged out"){
    #Executing login command for CLI
    m365 login   
}

#Set the URL of the site where the users need to be added
$siteURL = "https://aum365.sharepoint.com/sites/M365CLI"

#Getting the Associated Groups for the specific site
$SiteInformation = m365 spo web get --webUrl $siteURL --withGroups --output json | ConvertFrom-Json

#Importing the Current permission list from CSV. Adding the equivalent SharePoint Group Id to the imported object.
#Object will be grouped with multiple users with , seperator since CLI supports adding multiple users in a single command
$GroupedResult = Import-Csv -Path .\Current-Permission-Migration.csv | Group-Object PermissionLevel | ForEach-Object {
[PsCustomObject]@{
    PermissionLevel = $_.Name
    UsernameValues = $_.Group.Username -join ', '
    SPGroupId = switch ($_.Name){
        "Read" {"$($SiteInformation.AssociatedVisitorGroup.Id)"}#Adding to the default Visitor's Group
        "Member" {"$($SiteInformation.AssociatedMemberGroup.Id)"}#Adding to the default Member's Group
        "Owner" {"$($SiteInformation.AssociatedOwnerGroup.Id)"}#Adding to the default Owner's Group
        default {"$($SiteInformation.AssociatedVisitorGroup.Id)"}
        }
    }
}

#Show the Formatted data table for reference
$GroupedResult | Format-Table

#Read Grouped Permission level and users and add the users to the SharePoint Groups
Foreach ($PermissionLevel in $GroupedResult) {
    Write-Host "Adding $($PermissionLevel.PermissionLevel) Permission users to the SharePoint Group ID: $($PermissionLevel.SPGroupId)"
    #Since the command supports multiple usernames to be added in the single command, script will add users in single command execution
    m365 spo group user add --webUrl $siteURL --groupId $PermissionLevel.SPGroupId --userName $PermissionLevel.UsernameValues
