Will this produce the correct file?

require ‘csv’

headers = [‘id’,‘name’,‘dept’]
val_arr =
[
[1,2,3],
[‘sunil’,‘anil’,‘kumar’],
[‘IT’,‘IT’,‘IT’]
]

CSV.open(“data.csv”, “wb”) do |csv|
csv << headers
val_arr.transpose.each{|e| csv << e}
end

It looks like it will. Not trying to be flip, but the simplest way to find out is to try it and see.
