Create Active Directory Users from CSV with PowerShell

We want to create new Active Directory users in the organization. We can use the user creation wizard in Active Directory Users and Computers to create the users. What if you need to create 1000+ users? Doing it by the wizard will take a lot of time. In this article, you will learn how to create Active Directory Users from CSV with PowerShell.

Before you start to create Active Directory Users from CSV file

Let’s say you need one minute to create a new user with the wizard. It will take one minute for every user. What if you have to add a thousand new users? Do the math, 1000 users * 1 minute = 1000 minutes. That is approximately 16 hours. A bit too much time to spend on creating new users, right? What if you can simplify the process and do it much faster in time.

In the article, we are going to use the following files:

Create the CSV template

First, we need to make sure that we have a list of all the thousand users we need to create. The most important information that we need is the first name and last name. We suggest to create a CSV file and send it to a user in the company.

We are going to send the CSV file to Jane. Jane works in the HR department at the company called EXOIP. She does have the information regarding the thousand users that need a new AD user account. The CSV file that we send to Jane is NewUsersSent.csv. Jane will fill in the data, just like discussed, and send the CSV file back to us.

We told Jane to put as much information she can in the fields. If she can’t fill in all the fields, not to worry. The most important is the First name and Last name. We also told her to leave the Password and OU field empty. Why did we tell her that?

• Password field, leaving it empty because the IT department will create the passwords. Even if it’s a temporary password. When the user logs in, a prompt will show up to change the password.
• OU field, leaving it empty because the IT department will fill in the Organizational Unit (OU). That’s where the new Active Directory (AD) Users are going to be created.

Edit the CSV file

Jane sent the CSV file back with all the information. Let’s open the NewUsersReceived.csv file and have a look.

All is looking great. Jane did fill all the information that we need.

Generate passwords

Generate passwords for the users and fill the password fields for every user. I recommend generating passwords with Manytools password generator. You can create a maximum of 9999 passwords at one time. After that, copy and paste the passwords in the column Password.

Fill in the Organization Unit (OU)

Start Active Directory Users and Computers (ADUC) and make sure to enable Advanced Features. Click the menu View and click Advanced Features. Now that Advanced Features is enabled, we can proceed further and create the OU in AD.

We can see in the CSV file that the users are going to work in the IT department. We will create an OU in Active Directory with the name IT.

Right-click the OU with the name IT and click Properties. Click the tab Attribute Editor. Find the attribute distinguishedName. Double-click on it and copy the value. The value in my example is OU=IT,OU=Users,OU=Company,DC=exoip,DC=local.

Place the value in the fields under the column OU.

When done, save it as a new CSV file. Go to File and click Save As. Give it the file name NewUsersFinal.csv. Save it as type CSV UTF-8 (Comma delimited) (*.csv). Click the button Save.

The NewUsersFinal.csv is created.

Place the NewUsersFinal.csv in the C:\Temp folder on the Domain Controller or the Management Server.

Check the CSV file

Before using the script, import the CSV file in PowerShell. It’s an excellent way to check if it’s readable and if you’re all set.

Good to know about delimiter

Is the delimiter showing as a comma or semicolon in the CSV file? You need to know that if you are going to use the PowerShell script in the next step. If you use the semicolon as a separating character in your CSV file, add the delimiter parameter -Delimiter “;” to your Import-Csv cmdlet.

Run PowerShell as administrator. Use the Import-Csv cmdlet to read the CSV file. If it can’t read the CSV file, remove the -Delimiter parameter. It will be Import-Csv C:\Temp\NewUsersFinal.csv | Format-Table.

PS C:\> Import-Csv C:\Temp\NewUsersFinal.csv -Delimiter ";" | Format-Table

Prepare the Add-NewUsers PowerShell script

Download the Add-NewUsers.ps1 script and save it in path C:\Scripts on the Management Server or Domain Controller.

• Line 5 is the path of the CSV file. Change the path if you place the CSV file in another path. In our example, it’s C:\Temp\NewUsersFinal.csv.
• Line 5, remove the -Delimiter parameter if you have a coma separating character instead of semicolon in your CSV file. In our example, it’s the semicolon character.
• Line 8 is the UserPrincipalName (UPN). Change the UPN to yours. In our example, it’s exoip.com.

Run the Add-NewUsers PowerShell script

Change the directory path to C:\Scripts\ and run the script Add-NewUsers.ps1. The script will run and create Active Directory users in bulk. When done, press Enter to exit the screen.

PS C:\>cd C:\Scripts\
PS C:\Scripts> .\Add-NewUsers.ps1
The user account Max.Fraser is created.
The user account Piers.Bower is created.
The user account Kylie.Davidson is created.
The user account Richard.Grant is created.
The user account Boris.Campbell is created.
The user account Nicholas.Murray is created.
The user account Leonard.Clark is created.
The user account Ruth.Dickens is created.
The user account Jonathan.Fisher is created.
The user account Grace.Rees is created.
Press Enter to exit:

If the user already exists in AD, you will see the following.

PS C:\Scripts> .\Add-NewUsers.ps1
WARNING: A user account with username Max.Fraser already exists in Active Directory.
WARNING: A user account with username Piers.Bower already exists in Active Directory.
