I have a question that follows this thread. Its a follow up to this answer.

Google Apps Script Spreadsheets - Write Array to cells

how do i get

var employees=["Adam","Barb","Chris"];

to look like this?

var employees=[["Adam"],["Barb"],["Chris"]];

Answer 1

You could use map():

var employees=["Adam","Barb","Chris"];
var newEmployees = employees.map( function( item ){ return [ item ]; } );

• Sirko: @HMR But a suitable shim is given on MDN as well. So just add the shim and you should be alright.
• HMR: Yes, here is the map for browsers that don't implement it: developer.mozilla.org/en-US/docs/JavaScript/Reference/… Just needed mentioning if you need support for IE<9
• Sirko: @HMR Did you notice, that this link is already part of my answer?

Answer 2

var employees = ["Adam", "Barb", "Chris"];
for (var i = employees.length; i--;) {
 employees[i] = [employees[i]];
}
