input a csv/excel file -> convert to Drupal View and outputted to JSON

I need to take a file (CSV/Excel) as input (possibly through a drupal customer page), save in MySQL, Create views in Drupal, and output to JSON for a clientside to fetch the data over internet. The client being a mobile app is written in javascript and needs to create a table from the listed JSON string data. the csv/excel file will have the form: A | B | C | D | E | 1 Pizza 2 Pepperoni 3 Veggie 4 Margarita 5 6 Ice Creams 7 8 Chocolate 9 Vanila | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
