Can you post what you’re trying to do exactly?  A lot of folks here are willing to help (myself included) pro bono.  We just want to see people succeed!

I agree with ​@Chubs. From what it sounds like this could easily be done with a tool like The Mut without the need for any scripting.

My District is almost at the tail end of the device refresh.
Used MUT to preassign devices to students.

One thing to note:
If you have Jamf Account enabled in your server, you’ll need to create a local Jamf account and give it necessary permissions (modify, etc) for MUT to function.

Another note: MUT hates when you have a “ ‘ “ character in person’s name. It will crash instantly.
For those accounts, I’ve updated them manually via the Jamf Pro Admin Console. The reset used the spreadsheets with pre-populated information for name, username, building, asset number, etc.

You can also leverage this to add or remove devices from groups.
Create a group, then look up the unique group ID.

Works quite well.
