Json camel case formatted ouput

Hello,

We are working on a project that sends json formatted payload to a target system via a rest webservice. We would like to follow camel case standard for labels in the json payload. I did a sample program to generate a Json payload and it works fine. But i see that labels are framed from components of the structure. I need to know if its possible to replace the labels with a camel casing format...like messageType in place of MESSAGETYPE  or UniqueID in place of UNIQUEID etc..

Regards
