Output arrays to CSV - arrays

Question

I have two CSVs:
Total 19_01_16.csv:
hostname,user,path,size,creation,LastAccess,Copied,NewName,Completed
comp1,user1,\\comp1\users1\file.pst,100,17/02/2015,17/01/2016,Yes,file_user1_.pst,
comp1,user1,\\comp1\users1\file2.pst,200,17/02/2015,17/01/2016,Yes,file2_user1_.pst,
comp2,user2,\\comp2\users2\file.pst,100,17/02/2015,17/01/2016,Yes,file_user2_.pst,
PST Passwords.csv:
user,Path,Password1,Password2,Password3,Error
user1,\\comp1\users1\file.pst,openme,openme,openme,
I'm trying to merge the two with different headers and additional content.
This is what I have so far:
$a = Import-Csv "$PST_PARENT\DailyReports\Total 19_01_16.csv"
"Hostname,User,PST_Name,Original_Path,New_Path,Size,AcceptableLoss,Password1,Password2,Password3" |
Set-Content "$PST_PARENT\DailyReports\New Build.csv"
$a | foreach {
$HOSTNAME = $_.hostname
$USER = $_.User
$PATH = $_.path
$NEW_NAME = $_.NewName
$NEWPATH = "$PST_SHARE\$USER\$NEW_NAME"
$SIZE = $_.Size
$SIZE_FAIL = ( [convert]::ToSingle( $SIZE ) / 2 )
$b = Import-Csv "$PST_PARENT\DailyReports\PST Passwords.csv"
$b | foreach {
if ( $USER -like $b.user ) {
$PASSWORD1 = $b.password1
$PASSWORD2 = $b.password2
$PASSWORD3 = $b.password3
} else {
$PASSWORD1 = "none"
$PASSWORD2 = "none"
$PASSWORD3 = "none"
}
}
$HOSTNAME,$USER,$NEW_NAME,$PATH,$NEWPATH,$SIZE,$SIZE_FAIL,$PASSWORD1,$PASSWORD2,$PASSWORD3 |
Add-Content "$PST_PARENT\DailyReports\New Build.csv"
}
The output of New Build.csv looks like this:
Hostname,User,PST_Name,Original_Path,New_Path,Size,AcceptableLoss,Password1,Password2,Password3
comp1
user1
file.pst
\\comp1\users1\file.pst
\\share\PST_Storage\file_user1_.pst
100
5
none
none
none
In essence the output is working, it's just not scrolling for each line, it's putting each array onto a new line.
I tried adding | ConvertTo-Csv -NoTypeInformation but all that did was convert the arrays to numbers, they still went down not across.
Any ideas? Am I on the right line or doing the whole thing so very wrong?

$HOSTNAME,$USER,... defines an array, which is written to the output file one element per line. You need to put the list in double quotes to turn it into a comma-separated string that you can write to the output file as a single line.
"Hostname,User,PST_Name,Original_Path,New_Path,Size,AcceptableLoss,Password1,Password2,Password3" |
Set-Content "$PST_PARENT\DailyReports\New Build.csv"
$a | foreach {
...
"$HOSTNAME,$USER,$NEW_NAME,$PATH,$NEWPATH,$SIZE,$SIZE_FAIL,$PASSWORD1,$PASSWORD2,$PASSWORD3"
} | Add-Content "$PST_PARENT\DailyReports\New Build.csv"
or you construct a custom object from the elements that you can export via Export-Csv.
$a | foreach {
...
New-Object -Type PSCustomObject -Property #{
'Hostname' = $HOSTNAME
'User' = $USER
'NewName' = $NEW_NAME
'Path' = $PATH
'NewPath' = $NEWPATH
'Size' = $SIZE
'SizeFail' = $SIZE_FAIL
'Password1' = $PASSWORD1
'Password2' = $PASSWORD2
'Password3' = $PASSWORD3
}
} | Export-Csv "$PST_PARENT\DailyReports\New Build.csv" -NoType
