More about this script

Why use this template?

Use this when you already have a list of users and want to add them to an Active Directory group without hand-editing a PowerShell script.

The template uses ActiveDirectory. Preview is read-only; apply mode changes direct group membership. The generated script runs in your own PowerShell session.

Review before running

Review the target group and user matching choice before running. Preview first. Apply mode requires an explicit confirmation in the Builder.

Generate the script

Open the template in the PowerShell Builder.
Enter the requested values and review the module, permissions, output and risk.
Generate the script, read it carefully, and test it outside production before use.

The script is generated locally in your browser. Nothing needs to be uploaded to Opselith.
