PowerShell script to create AD groups from a .CSV file

Here is a script that I used recently on a project that might be of use to you all.

You need to pass the .csv file as a parameter and let the script do the rest!

The file has to be in the format of:

ADGroupName
MyGroup1
MyGroup2
MyGroup3

The script is below:

)

###########################################################################################
#Set the DC, OU domain information - Set depending on your environment
$objOU = [ADSI]"LDAP://localhost:389/OU=YourOUName,DC=Example,DC=com"
###########################################################################################

#Check that we have an AD grouplist
if ($ADGroupFile -ne "")
{
    #loop over the groups in the .CSV file
    ipcsv $ADGroupFile | foreach {

            #get the ADGroupname from the .CSV
            $ADGroupName = $_.ADGroupName;
            #ensure the site name isnt empty or blank
            if ($ADGroupName -ne "")
            {
                Write-Host -ForegroundColor green "###########################################################################################";
                Write-Host -ForegroundColor green "Adding ADGroup - $ADGroupName";
                #Create the AD Group
                $objGroup = $objOU.Create("group", "CN=" + $ADGroupName)
                $objGroup.Put("sAMAccountName", $ADGroupName )
                $objGroup.SetInfo()
                Write-Host -ForegroundColor green "###########################################################################################";
                Write-Host;       
            }       
    }   

    Write-Host;
    Write-Host -ForegroundColor Yellow "**AD Group Processing complete**";   
}
else
{
    Write-Host -ForegroundColor red "You must specify the AD group file.";
