JSONImport		/application/libraries/JSONImport.php

This library handles nilai data import from JSON file.

Design goal is ability to process huge data sets regardless of their size. So instead of loading data into memory and parsing using json_decode, we're processing input file line by line wherever possible. For that the file needs to be properly formatted. For more details about format see JSON Export.
