Export azure ad groups membership via powershell - powershell

Question

I need help in the powershell script. I am looking to get Azure AD, group membership details for multiple groups which are in the CSV file.
The format, I am looking to get is:
Group Name :SG-Test-Users
Members: xyz, abc etc
Output needed in this format
Please help
I tried, below script but it is not giving an output in the format I am looking for.
Import-Csv -Path "C:\temp\testgroup.csv" | ForEach-Object {Get-AzureADGroupMember -ObjectId $_.name | select displayname,userprincipalname} | Export-Csv -Path "c:\temp\outputfile1.csv" -NoTypeInformation
Thanks,

Answer 1

Try the command below, it works fine on my side. Note it will append data to the file instead of overwriting.
$csv = Import-Csv "C:\Users\joyw\Desktop\testgroup.csv"
foreach ($line in $csv){
$groupname = $line.GroupName
$objectid = (Get-AzureADGroup | Where-Object {$_.DisplayName -eq $groupname}).ObjectId
Get-AzureADGroupMember -ObjectId $objectid | select DisplayName,UserPrincipalName | Export-Csv -Path "C:\Users\joyw\Desktop\outputfile1.csv" -NoTypeInformation -Append
}
My test file:
testgroup.csv
outputfile1.csv

I'm new to this, but here's my take
try below (modify output as required) and then save the console output to file and massage as required in excel
cheers
$gg=Get-AzureADGroup -top 200
ForEach ($g in $gg){
$a = Get-AzureADGroup -ObjectId $g.ObjectId
$b = Get-AzureADGroupMember -ObjectId $g.ObjectId -All $true
ForEach ($c in $b){
Write-host $a.DisplayName ";" $c.ObjectId ";" $c.ObjectType $c.UserType ";" $c.UserPrincipalName
}
}

$ResourceAuditArray = #()
ForEach ($g in Get-AzureADGroup -SearchString "<first word of groups e.g. DFC, ADF, DAS>"){
$ResourceAuditArray += Get-AzureADGroupMember -ObjectId $g.ObjectId -All $true | Select-Object ObjectId, ObjectType, UserType, UserPrincipalName, #{n="DisplayName"; e={$g.DisplayName}}
}
$ResourceAuditArray | Export-Csv "<AAD Users list>.Csv"
