🏷️ Accessing Columns via Headers

Enabling headers: true treats the first row as field names, letting you refer to columns by header instead of index. This improves readability and reduces errors when the column order changes.

require 'csv'

CSV.foreach('users.csv', headers: true) do |row|
  puts "User: #{row['username']}, Email: #{row['email']}"
end
