Override labels in REST Export view I have a REST EXPORT view getting fields values of a node. I want to override the labels of these fields in the response returned. 
For example:- the returned response like this 

[ 
    { 
        "question_title": "How are you?", 
}
]


I want the response like this

[ 
    { 
        "questionTitle": "How are you?", 
}
]


I tried to create label from the view but it doesn't affect.
In your view's row style options you can rename any exposed field's label. The form labels those fields as alias.

This is screenshot from another view I was working on, but should give you an idea.
