Parent Child Tree with powershell

Hi all,

i try to recursivly read groups from AD and want to display the output like a tree.
therefore i created an object like this:

ID : 15
ParentID : 7
AnzeigeName : DevAdmin
SamAccountName : DevAdmin
DistinguishedName : CN=DevAdmin,OU=Work,DC=forest1,DC=net
FromGroup : CN=Domain Admins,CN=Users,DC=forest1,DC=net
objectClass : user
Level : 2

ID : 7
ParentID : 0
AnzeigeName : Domain Admins
SamAccountName : Domain Admins
DistinguishedName : CN=Domain Admins,CN=Users,DC=forest1,DC=net
FromGroup : CN=DLTest,CN=Users,DC=forest1,DC=net
objectClass : group
Level : 1

How can i get all the objects sorted that all objects with ParrentID -eq X are displayed unter objects with ID -eq X??
Any idea?

Just pipe the results to Group-Object

$groupedData = $yourData | Group-Object ParentID

Then, you will have all of your IDs in the “Name” column and the matches in the “Group” column. Manipulate that how you see fit.

Okay this worked so far i have a the parrentIDs and their childs.
How can this help me to build a tree structure?
So far I have one parent and one Child?

To start out, we want to group the parent and the child objects together:

$tree = @()

foreach ($object in $groupedData) {
    $data = New-Object psobject
    $data | Add-Member -Type NoteProperty -Name "Parent" -Value $(($yourData | where {$_.ID -eq $($object.Name)}))
    $data | Add-Member -Type NoteProperty -Name "Child" -Value $($

    $tree += $data

At this point, $tree has the “Parent” value and each of the “Child” values. So it’s purely cosmetic at this point.

Look here for inspiration if you are wanting to create a tree-map.

Otherwise, you can pipe $tree to something like ConvertTo-HTML, ConvertTo-JSON or ConvertTo-XML. XML or JSON would probably give you the closest to a tree without all of the additional coding.
