Including line breaks in side by side open ended question

hey ​@JohnR , instead of working on Question JS, try it in the code task just above your excel task. add the below code in your code task - 

function codeTask() {

    var entry1 = "${q://QID6%231/ChoiceTextEntryValue/3/1}";
    var entry2 = "${q://QID6%231/ChoiceTextEntryValue/2/1}";
    var entry3 = "${q://QID6%231/ChoiceTextEntryValue/1/1}";

    var entries = [entry1, entry2, entry3].filter(function(e) {
        return e.trim() !== "";
    });

    var formattedText = entries.join("\r\n");

    return {
        result: formattedText,
        success: true
    };
}

and use the above code task result in your excel task’s header value. so the setup should look like below - 

below is how your code task should look like - 

then in your excel task, use the yellow highlighted button to select the result of the above code task - 

once done, publish the workflow and test it. I did get the output as expected in a single cell, one below another rather than a long list

let me know if it works for you!
