Ruby 1.8.7 Parsing CSV Files Without FasterCSV

Working With CSV Files In Ruby 1.8.7 Without FasterCSV

The following Ruby code sample shows how to bring in data from a csv file with headers in a way that allows you to manipulate the date by header name.

inputfile = ARGV[0]
csv = CSV.open(inputfile, 'r')
Column = Struct.new(*(csv.shift.map { |f| f.to_sym }))
  columns = csv.inject([]) do |columns, row|
  columns << Column[*row]
end
csv.close
columns.each do |c|
  column1 = c.column1header
  column2 = c.column2header
  column3 = c.column3header
  column4 = c.column4header
  <put your code that uses the column names to do whatever it is you need to do here>
end
