Expanding System.Object[] for Export to CSV - powershell

Question

Hello again and sorry!
To keep it really short. What am i doing wrong?
Im attempting to export a list of users filtered by using a customobject to a CSV and it outputs it into the same block. Is there no way to change this? I only ask because, all the other pages ive looked at it keeps telling me to use -join, to join them as strings which does the exact same thing. Is it not possible to output it as multiple rows for each user?
$GPMem = Get-ADGroupMember -Identity security.group | Select-Object -ExpandProperty Name
[array]$TPpl = $GPMem | Where-Object {$_ -like "T*"}
[array]$RPpl = $GPMem | Where-Object {$_ -like "r*"}
[array]$CPpl = $GPMem | Where-Object {$_ -like "c*"}
[pscustomobject]#{
TPeople = (#($TPpl) |Out-String).Trim()
TPCount = $TPpl.Count
RPeople = (#($RPpl) |Out-String).ToString()
RPCount = $TPpl.Count
CPeople = $CPpl
CPCount = $TPpl.Count
} | Export-Csv -Path C:\Users\abraham\Desktop\csv.csv -NoTypeInformation -Force

Answer 1

here is how to insert a ; OR newline into the values of a column ... [grin]
$ThingList = #('One Thing', 'Two Thing', 'Three Thing')
$ThingList -join '; '
'=' * 20
$ThingList -join [System.Environment]::NewLine
output ...
One Thing; Two Thing; Three Thing
====================
One Thing
Two Thing
Three Thing

Answer 2

create 3 more arrays for the count (each array will be exported to a column), then find the array with the most count and generate a psobject for each line.
[array]$TPpl = #("T1" ,"T2", "T3")
[array]$TPpl_count = #($TPpl.Count)
[array]$RPpl = #("R1" ,"R2", "R3", "R4")
[array]$RPpl_count = #($RPpl.Count)
[array]$CPpl = #("C1" ,"C2", "C3", "C4","C5")
[array]$CPpl_count = #($CPpl.Count)
$leng = [array]$TPpl.Count,$RPpl.Count,$CPpl.Count
$max = ($leng | measure -Maximum).Maximum
$csv = for($i=0;$i -lt $max;$i++){
New-Object -TypeName psobject -Property #{
"TPeople" = $(if ($TPpl[$i]) { $TPpl[$i]})
"TPCount" = $(if ($TPpl_count[$i]) { $TPpl_count[$i]})
"RPeople" = $(if ($RPpl[$i]) { $RPpl[$i]})
"RPCount" = $(if ($RPpl_count[$i]) { $RPpl_count[$i]})
"CPeople" = $(if ($CPpl[$i]) { $CPpl[$i]})
"CPCount" = $(if ($CPpl_count[$i]) { $CPpl_count[$i]})
}
}
$csv | Export-Csv C:\Temp\test.csv -NoTypeInformation
result:
your final code should be:
$GPMem = Get-ADGroupMember -Identity security.group | Select-Object -ExpandProperty Name
[array]$TPpl = $GPMem | Where-Object {$_ -like "T*"}
[array]$RPpl = $GPMem | Where-Object {$_ -like "r*"}
[array]$CPpl = $GPMem | Where-Object {$_ -like "c*"}
[array]$TPpl_count = #($TPpl.Count)
[array]$RPpl_count = #($RPpl.Count)
[array]$CPpl_count = #($CPpl.Count)
$leng = [array]$TPpl.Count,$RPpl.Count,$CPpl.Count
$max = ($leng | measure -Maximum).Maximum
$csv = for($i=0;$i -lt $max;$i++){
New-Object -TypeName psobject -Property #{
"TPeople" = $(if ($TPpl[$i]) { $TPpl[$i]})
"TPCount" = $(if ($TPpl_count[$i]) { $TPpl_count[$i]})
"RPeople" = $(if ($RPpl[$i]) { $RPpl[$i]})
"RPCount" = $(if ($RPpl_count[$i]) { $RPpl_count[$i]})
"CPeople" = $(if ($CPpl[$i]) { $CPpl[$i]})
"CPCount" = $(if ($CPpl_count[$i]) { $CPpl_count[$i]})
}
}
