Using Javascript to convert 15 char SF IDs to 18 char IDs [duplicate]

Question

I'd like to create a macro for Keyboard Maestro that will take a highlighted 15 char ID and use javascript to convert it to a an 18 char ID. I understand how that conversion takes place but am a beginner at Javascript. Could anyone help in the creation of the javascript that I can use in my macro?

Thanks!

Here is one algorithm (copied verbatim below).

function normaliseSforceID( id) { // fluff up a 15 char id to return an 18 char id
    if (id == null) return id;
    id = id.replace(/\"/g, ''); // scrub quotes from this id
    if (id.length != 15) {
        //print('well, id is not 15, bye' + id + ' ' + id.length);
        return null;
    }
    var suffix = "";
    for (var i = 0; i < 3; i++) {
        var flags = 0;
        for (var j = 0; j < 5; j++) {
            var c = id.charAt(i * 5 + j);
            if (c >= 'A' && c < = 'Z') {
                flags += 1 << j;
            }
        }
        if (flags <= 25) {
            suffix += "ABCDEFGHIJKLMNOPQRSTUVWXYZ".charAt(flags);
        } else {
            suffix += "012345".charAt(flags-26);
        }
    }
    return id + suffix;
}

Note that if you are trying to do this conversion on a Visualforce Page you can just use "{!CASESAFEID(idValue)}".
