Importing users from CSV into AD with PowerShell - powershell

Question

I'm using the following script in order to import 100,000 users from a CSV file into Active Directory. However, I'm getting a lot of errors and need your help in eliminating them.
Script:
Import-Csv C:\csv\100Kusers.csv | ForEach-Object {
$userPrinc = $_."Logon Username" + "#mydomain.com"
New-QADUser -Name $_.Name `
-ParentContainer $_."Container" `
-SamAccountName $_."Logon Username" `
-UserPassword "passw0rd123" `
-FirstName $_.FirstName `
-LastName $_."LastName" `
-Description $_."Department" `
-UserPrincipalName $userPrinc `
-DisplayName $_."Name" `
-StreetAddress $_."StreetAddress" `
-City $_."City" `
-State $_."State" `
-PostalCode $_."PostalCode" `
-Email $_."Email" `
-Company $_."Company" `
-Department $_."Department" `
-HomePhone $_."HomePhone" `
-Title $_."Title" `
-Manager $_."Manager" ;`
Add-QADGroupMember -identity $_."Group" -Member $_."Logon Username" ;`
}
And here are the errors I'm getting:
Add-QADGroupMember : Cannot resolve directory object for the given identity: 'jm?lmhx4'.
At C:\csv\PS_import_script.ps1:22 char:2
+ Add-QADGroupMember -identity $_."Group" -Member $_."Logon Username" ;`

CSV looks like this:
FirstName Surname Name StreetAddress City State PostalCode EmailAddress Company Department Group HomePhone Title Manager Logon Username Container

Sorry, can't add more - formatting goes crazy when I copy a plain CSV into the post window.

Answer 1

Many thanks everyone. I agree that this could be an encoding issue and yes, the CSV itself had all those off "?" marks, after I saved it from xlsx format. We ended up using Pyhthon, which also was much faster, comparing to Pshell.
