converting CSV/XLS to JSON?

csv, json, xls

Solution

This worked perfectly for me and does NOT require a file upload:

Problem

Does anyone know if there is application that will let me convert preferably XLS to JSON? I'll also settle for a converter from CSV since that's what I'll probably end up having to write myself if there is nothing around.
