Mirth CSV file to collection of JavaScript literals

mirth-csv-to-array.js

//the Mirth file reader has a CSV file (now in the msg object)
//be sure your channel's incoming data type is 'delimited text'

//let's pretend this csv contains customers
var customers = [];
var header = msg.row[0];
for(var i=1;i<msg['row'].length();i++)
{
	var cust = {};
	for (col in msg.row[i].children()) {
		var columnName = header.children()[col];
		//set the customer property, by name, based on the name of the column in the header row
		cust[columnName] = msg['row'][i].children()[col].toString();
	}
	customers.push(cust);
}

//you now have an array of customer objects. 
channelMap.put("customers", customers);
