When it comes to handling structured data in Perl, the Comma-Separated Values (CSV) format is a popular choice due to its simplicity and widespread compatibility. Writing data to a CSV file in Perl is a straightforward process, thanks to Perl's built-in modules specifically designed for CSV file manipulation. Below, I'll guide you through the steps to write CSV files in a Perl script.
