Mastering Export-CSV Filtering in PowerShell

PowerShell is a powerful scripting language that enhances your ability to manage and manipulate data. However, often when exporting data from CSV files, you might run into issues such as unwanted headers and formatting tags. One common scenario involves extracting a specific column from a CSV file and saving it cleanly into a .txt file. If you've been wondering how to achieve that, you're in the right place.
