I have a file containing the data ( as obtained from Twitter4J methods like twitter.showUser()) and each of the line looks like

            },
            UserMentionEntityJSONImpl{

            }
        ],
        mediaEntities=[

        ],
        currentUserRetweetId=-1,
        user=null
    },
    profileBackgroundColor='FFFFFF',
    profileTextColor='343434',
    profileLinkColor='AAAAAA',
    profileSidebarFillColor='BDBDBD',
    profileSidebarBorderColor='FFFFFF',
    profileUseBackgroundImage=true,

    isGeoEnabled=false,
    isVerified=false,
    translator=false,
    listedCount=544,

}

I would like to convert this data format to a plain text format with all the fields.

Thank you for the help

There are several APIs around for JSON - processing.
The new JSR-353 (part of JEE 7) could be useful to you , you could try http://www.jdom.org/ just to mention two.
Both mainly iterate over the complete JSON - Object which can be constructed from a JSON - String.
So how to want to format your text?
If you just want to put everything into a text - file you could append to a String member of your Main - class,
if you want to produce a csv -text -file you are translating between two different views of a data model
and should build a proper data model for the csv - file before creating the view of it, the actual csv - file.
