read a csv file using powershell - powershell

Question

I'm struggling with reading and writing a csv file using power shell. I need to read a file containing three columns Servers, Users, Status
I've completed the first step (read in the file)
The next step is to split the data in the Status field by its delimiter ';' (I have that as well)
Now where the problem comes in is where I loop thru a Get-ADUser and build the print line putting all the values in the foreach loop together - seperated with a ';'. (new status field)
Then of course at the conclusion write out the completed file.
so the input file is a csv that contains the following
Server Users Status
ABC xtom
JKL
CDEA msall;jbec
The output csv would be
Server Users Status
ABC xtom xert.tom#abc.com;
JKL
CDEA msall;jbec mik.sall#abc.com;jay.bec#abc.com
my code as it stands
$List = Import-Csv -Path "c:\data\infile.csv"
$outarray = #()
foreach ($item in $List)
{
Write-output $item
$Servers= $($item.Server)
$Users = $($item.Users)
$Status = $($item.Status)
if ($Users.length -gt 0)
{
$CharArray =$Users.Split(";")
Foreach ($i in $CharArray)
{
$email = Get-ADUser -Filter {SamAccountName -like $i} | Select -Property UserPrincipalName
$outarray = $email
}
}
}
$outarray | Export-Csv "c:\data\testout.csv" -noType
Any help would be appreciated
Thanks
The csv input file
Server,Users,Status
ABC,xtom,
JKL,,
CDEA,msall;jbec,
the csv output file
Server,Users,Status
ABC,xtom,xert.com#abc.com
JKL,,
CDEA,msall;jbec,mik.sall#abc.com;jay.bec#abc.com

So, if I understand correctly what you need this code should work for you:
$List = Import-Csv -Path "c:\data\infile.csv"
$outarray = [system.collections.generic.list[pscustomobject]]::new()
foreach ($item in $List)
{
Write-output $item
$Server = $($item.Server)
$Users = $($item.Users)
$Status = $($item.Status)
if ($Users)
{
$CharArray = $Users.Split(";")
$email = $(
Foreach ($i in $CharArray)
{
$usr=(Get-ADUser -Filter {SamAccountName -like $i}).UserPrincipalName
if($usr){$usr}
}) -join ';'
}
$outarray.Add(
[PSCustomObject]#{
Server = $Server
Users = $Users
Status = $email
})
}
$outarray | Export-Csv "c:\data\testout.csv" -NoTypeInformation
It's worth mentioning that userPrincipalName is definitely not the same thing as mail even though they can look the same this may not always be the case.
Also, if $i will actually contain samAccountNames then -Filter {....} is not needed.
