and convert it into

[["","104","","","Testing"........], ["" ......]

The Hash class has the method values which returns an array of all the values.

my_hash = {"6" => "", "7" => "104"}
my_array_of_values = my_hash.values # ["", "104"]

In Ruby, the Hash contains key/value pairs (eg. { key => value }). The keys method returns an array of the keys and the values method returns an array of the values.

Read more about the values method here: http://ruby-doc.org/core/classes/Hash.html#M002867
