public class CDL
extends java.lang.Object

This provides static methods to convert comma delimited text into a JSONArray, and to covert a JSONArray into comma delimited text. Comma delimited text is a very popular format for data interchange. It is understood by most database, spreadsheet, and organizer programs.

Each row of text represents a row in a table or a data record. Each row ends with a NEWLINE character. Each row contains one or more values. Values are separated by commas. A value can contain any character except for comma, unless is is wrapped in single quotes or double quotes.

The first row usually contains the names of the columns.

A comma delimited list can be converted into a JSONArray of JSONObjects. The names for the elements in the JSONObjects can be taken from the names in the first row.
