The answer about: how will it work? Please help ?

Answer by thekillerkat
This code is incomplete..
But it looks like it’ll read data from a file. This file should contain data in CSV(comma seperated value) format..
You read the data, do the conversion and put the result..

Not rocket science, can very easily be coded by a newbie ..
