remove the space in keys in a nested object using javascript

I want to replace the whitespace of keys in a nested object. I have an object as follows:

     var data = 
 { 'General Information':
             { 'Referral No': '123123',
               Marketer: '',
               Casemanager: 'Alexis Clark',
               'CM Username': '',
               VOC: '',
               'Foreign Voluntary': '',
            },
     'Account Name': 'CTS Health',
    }

What i did is:

 for (var k in data) {
    if (k.replace(/\s/g, '') !== k) {
        data[k.replace(/\s/g, '')] = data[k];
        if (data[k] !== null && typeof data[k] === 'object') {
            for (var x in data[k]) {
                if (x.replace(/\s/g, '') !== x) {
                    data[k][x.replace(/\s/g, '')] = data[k][x];
                    delete data[k][x];
                }
            }
        }
        delete data[k];
    }
}

I get this:

{ GeneralInformation:
         { 'Referral No': '123123',
           Marketer: '',
           Casemanager: 'Alexis Clark',
           'CM Username': '',
           VOC: '',
           'Foreign Voluntary': '',
        },
    AccountName: 'CTS Health',
  }

What i want is:

{ GeneralInformation:
         { ReferralNo: '123123',
           Marketer: '',
           Casemanager: 'Alexis Clark',
           CMUsername: '',
           VOC: '',
           ForeignVoluntary: '',
        },
    AccountName: 'CTS Health',
  }

What am i doing wrong here??
