You haven't clearly stated what you want this spreadsheet to look like so I can't be specific but you can use the YAML library to read the file into a data structure, then convert the data structure into one like a table (array of arrays of strings) then use the CSV library to output it to a file.

require 'yaml'
require 'csv'

yaml_txt = File.read 'input.yaml'
yaml_data = YAML.load yaml_txt

csv_table = [
    [1,'hello world', true], 
    ['a', 'b', 3.14159, 'c', 2, 3e8], 
    [nil, 'another row', 'bla']
]
#replace this^ with something that converts the yaml_data into a 2D array

File.open 'output.csv', 'w' do |f|
    f.puts( csv_table.map do |row|
        CSV.generate_line row
    end.join "\n" )
end

The current example will produce:

1,hello world,true
a,b,3.14159,c,2,300000000.0
,another row,bla

in output.csv.

You can then open the CSV spreadsheet with the following options:

think, it's better to join rows with an empty string rather than "\n"
