In Grails, We often use

render list as JSON.

It renders json output without any formatting (spaces and new lines), often we need to provide users an option to receive formatted json (pretty printed) as response, so that it could easily be read and understood by users.

We can easily do that using

def json = doc as JSON
json.prettyPrint = true
json.render response

This renders json in pretty printed format, which is much easier for humans to read and understand.
