i tried that first:

var msg = {payload:msg.payload};

var msg2 = msg.replace(/"_"/g, " ");

return msg2;

but just get a TypeError: msg.replace is not a function

That is because msg.replace() is not a function while replace() is…

You need to look at the example again. Your first go was nearly
right, the difference is that you have quotes round the underscore
which means it is looking for "_" including the quotes.

Hi Chris,

the problem in your code was too many quotes in the regular expression you're passing to msg.payload.replace()

    var msg = {payload:msg.payload.replace(/_/g, " ")};

    return msg;

But note, in general you should reuse the message passed in rather than create a new message object. So the following would be better:

    msg.payload = msg.payload.replace(/_/g, " ");

    return msg;
