John AJFKC

Answer 1

You can do the following if there will always be 2 codes per name:
Import-Csv file.csv | Foreach-Object {
$codes = ($_.Codes -split ',').Trim()
[pscustomobject]#{Name = $_.Name; Codes = $codes[0]}
[pscustomobject]#{Name = $_.Name; Codes = $codes[1]}
}
If the number of codes per name is unknown, you can do the following:
Import-Csv file.csv | Foreach-Object {
$codes = ($_.Codes -split ',').Trim()
foreach ($code in $codes) {
[pscustomobject]#{Name = $_.Name; Codes = $code}
}
}

Answer 2

If this is how this file really looks, it's not a Csv file. It's just a text file based copying and using what you posted. It's left-justified, vs columns, here the staggered look of it. The file has 5 spaces for that name column between it and that left justified Codes column with a code array.
So, though it looks like a table/tabular format, it's not really that. As in an import that name column would include the first of the code strings, thus cause some issues with your desired output. So, that text file would need to be manipulated a bit more, or who or whatever provides you the file, should make is a legitimate CSV.
So, here's my take on the assumptions in the aforementioned.
(Get-Content -Path 'D:\Temp\UserRecord.csv') -replace ', ',',' |
Select -Skip 2 |
ForEach {
$Name = (($PSItem) -split '\s+')[0]
($PSItem -split '\s+')[1] -split ',' |
ForEach {
[PSCustomObject]#{
Name = $Name
Codes = $PSItem
}
}
}
# Results
<#
Name Codes

try this:
Import-Csv "c:\temp\test.csv" -Delimiter "`t" | %{
$Name=$_.Name
$_.Codes -split "," | %{ [pscustomobject]#{Name=$Name;Code=$_.Trim()}}
}
