I added a custom column in customer grid i.e subscriber_status which is showing correctly. In DB the actual value saved as either 1(subscribed) or 3(unsubscribed).
Currently I am able to manipulate data i.e 1 as YES and 3 as NO text which I am displaying in my custom column but when I am exporting CSV data is displaying as 1 or 3 .
But I want it to show either YES or NO in CSV.
