Group Membership report script - Modify to change format of output

Question

Hi all,
Slowly getting to grips with Powershell. Such a powerful tool.
I've been tasked to develop a reporting script that will output a list of members of a set of groups and have found one of the scripts here to be a great starting point.
So this is the script:
"Import-Module ActiveDirectory
cd AD:
$MemberList = New-Item -Type file -Force “C:\Scripts\GroupMembers.csv”
Import-Csv “C:\scripts\grps.csv” | ForEach-Object {
 $GName = $_.Samaccountname
 $group = Get-ADGroup $GName
 $group.Name | Out-File $MemberList -Encoding Unicode -Append
  foreach ($member in Get-ADGroupMember $group) {$member.SamaccountName | Out-File $MemberList -Encoding Unicode -Append}
$nl = [Environment]::NewLine | Out-File $MemberList -Encoding ASCII -Append
The output lists the group name and the members of said group using Sam account name.
Ideally I would like that the email address of the user be in the output instead of SAMACCOUNTNAME however I realise that this may not easily be achievable due to the output of get-adgroupmember.
I'd also like if the output contained each of the email addresseses of the group members to be on the same line seperated by a semicolon in one cell directly under the group name.
EG:
GROUPNAME1
[email protected];[email protected];[email protected]
GROUPNAME2
user15:mail.com
Etc
Can either of these requirements be achieved from modifying the script above and any help would be much appreciated.
Thanks for any assistance.

You're welcome, glad I could help out.
Here's the same code with some comments and syntax links:
# Import the CSV file and process each record
Import-Csv .\grps.csv | ForEach {
# Set the group name as a variable for easy use later
# This really isn't necessary, but I do it for easy reading
$groupName = $_.SamAccountName
# Get the group members of the current group and process each user
# The output of this loop will be stored in a single variable
$groupMembers = Get-ADGroupMember -Identity $groupName -Recursive | ForEach {
# Get the user account and select only the EmailAddress property
Get-ADUser -Identity $_.SamAccountName -Properties EmailAddress |
Select -ExpandProperty EmailAddress
# Create a hashtable from the data above
# The group members are sorted and then joined using ; as a delimiter
$props = @{
GroupName = $groupName
Members = ($groupMembers | Sort) -join ';'
# Create a new object based on the hashtable above
New-Object PsObject -Property $props
} | Select GroupName,Members | Export-Csv .\groupMemberships.csv -NoTypeInformation
# Select is used to ensure the correct column order and then an output CSV is created
