Does anyone here know how to convert from CSV to JSON

I have been trying to modify Tigerman's player file to update the contracts and the drafted year information for all players. Having said that, I don't know how to get the information back into JSON format (there are, apparently, several versions of this). I am not a JAVA Script writer, so this is something I would have to learn. I'd rather have someone guide me to where I need to get the specific information instead of the general "search the internet" or "go to this website and read this."
The bottom line is that I am trying to test my work and will not be able to do so if I can't get the files back into JSON format. I have tried to contact Tigerman but have had no luck.
