Look inside

As a PowerShell developer, your critical mission is to help XYZ Services company, the consulting and outsourcing firm you work for, avoid payroll delays after a massive failure in its IT infrastructure. To meet a requirement in the input process to payroll, the HR department needs an update to the state field in the source file to be changed from the employee’s state of residence to the state of the office they report to. Using PowerShell best practices, you’ll write a script that uses the switch statement, PowerShell cmdlets, and advanced regex expressions to read the input file, return a list of the unique states within the file, replace the state value according to the predefined conditions—and keep those paychecks coming.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
