A Step-by-Step Guide to Adding an Array as a Column to CSV File Using PowerShell

If you've been working with data in Excel and want to export it into a CSV file with specific formatting, you might encounter some challenges—especially if you're new to PowerShell. One common problem is wanting to combine data from multiple arrays into a structured CSV format. In this post, we will walk through a straightforward method to achieve that, even for those who are still getting comfortable with PowerShell.

Step 1: Retrieve Data from Excel

To begin with, the first step is to extract the data from your Excel file. This is accomplished using PowerShell's UsedRange property. Here's how you can retrieve the email and response values:
