A quick hack to convert a CSV table filled with contact details into a vCard.

csv2vcf.rb

#!/usr/bin/env ruby

require 'csv'
require 'erb'

def main
  vcard_template = ERB.new(DATA.read)
  CSV.parse(STDIN, headers: true).each do |row|
    name  = row['Namn']
    email = row['Email']
    skype = row['Skype']
    phone = "+46" + row['Telefonnummer'].gsub(/[ -]/, '')[1..-1]
    bday  = Date.parse(row['Personnummer'][0..-5]).strftime
    puts vcard_template.result(binding)
  end
end

main if $0 == __FILE__

__END__
