How to convert date (1991-08-23T00:00:00) which is captured in response and then convert this format (08-23-1991) in vugen? - scripting

Question

I am working on a script where I need to submit a form and do some authentication during the steps. I am using LoadRunner Vugen for scripting. For one of the request's response I can see birthdate is coming like below:
"suffixName": ""
"birthDate": "1991-08-23T00:00:00",
"agencyName": ""
In another later request I can see in jason body the same date is used like below
"Body={\agentSuffix":null,"agentFirstName":"XYZ","agentLastName":"WSD","agentBirthDate":"08-23-1991" and so on with additional body.
I am able to capture the date from response by using web_reg_save_param_ex. But now how do I convert the value so that I can use it in next jason body in a custom request. I just need help to capture it.
Captured value: 1991-08-23T00:00:00
Expected value: 08/23/1991
Thanks in advance

Correlate for the string
Use your programming skills in the language of your virtual user to transform transform the string into a new string. Your test code might be C, JavaScript, Java, ... so use language-appropriate string conversion functions.

"LB=birthDate":"", "RB=T00:00:00"
Conside the loop and what this means for the use of substring and sprintf();
for (counter=0;counter<=strlen(lr_eval_string(MyCorrelatedVarName));counter++)
{ lr_message("%s",&lr_eval_string(MyCorrelatedVarName)[counter]); }
