Actually, my requirement is to convert whole JSON(only keys) into lowercase. I tried it's converting only first key of that JSON and it's not converting whole all key. Please have a look the fiddle link or please provide any other ways to do this.

Thanks...

var obj = {

  Collections: {

    conTainer: {

      rowSet: [{

        containerIsArchived: Null,

        containerOrderNo: 26,

        versionNum: 0,

        containerGlobalUniqueId: Null,

        containerIsTenantBased: true,

        containerCreatedBy: user,

        containerIsDeleted: false,

        containerTenantId: 292FEC76-5F1C-486F-85A5-09D88096F098,

        containerLayoutId: 4e13dfcd-cd3b-4a29-81bd-0f73cf9577cf,

        containerApplicationId: 0000000-0000-0000-0000-000000000000,

        containerIsActive: Null,

        containerHeaderText: apitest19feb16,

        containerId: 3745b273-c48d-4c94-b576-3d7aac2f7ac6,

        containerCreatedUTCDate: 2016-02-19 17:57:51.0

      }]

    }

  }

};



convertKeysToCamelCase(obj);



function convertKeysToCamelCase(obj) {

  if (!obj || typeof obj !== object) return null;



  if (obj instanceof Array) {

    return $.map(obj, function(value) {

      return convertKeysToCamelCase(value);

    });

  }



  var newObj = {};

  $.each(obj, function(key, value) {

    key = key.charAt(0).toLowerCase() + key.slice(1);

    newObj[key] = value;

  });

  console.log(newObj);

  return newObj;

};
