Downloadable CSV file here

For instance, output all the column headings, and row data etc to a table displayed on the HTML

Most of the research online seems to focus on incoming csv data similar to JSON data. But I cannot quite seem to find one that parses a CSV file. Any help or direction will be much appreciated.

    Usually CSV files contains cells divided by a separator, like ;: in your example the separator is ,. So what you need to do is:

    1) Read your CSV file into a String, for example you can name it input;

    2) Create a String Array like this String[] result = input.split("\\,");;

    3) Iterate your result as you wish.
