importing magento export CSV files into spree

import.rb

require 'fastercsv'
n = 0

FasterCSV.foreach("export_all_products.csv") do |row| 
  if n != 0
    puts "Adding new product: #{row[7]}"
    product = Product.new
    
    product.name = row[7]
    product.description = row[27]
    product.sku = row[5].to_s
    product.price = row[22].to_d
    product.save!
  end
  n += 1
end

puts ""
puts "Import Completed - Added: #{n} Products"

Just run the following command (so the script has access to the database):
script/runner import.rb
and you're done.

If only my use case was that simple :-)
