Elastic Stack Logstash

Hello Friends,
Need your help to parse string into Json format in logstash.

{
   "id":"xxx",
   "MessageCreateDate":"2022-01-20",
   "Response":"{'Cardholder':{'cards':[{'isPrimaryCard':'N','cardNumber':'xxxxxxxxxx','referenceID':'xxxxxxx','customerId':'xxxx
xxxxxxxxxxxxx','billingCurrencyCode':'xxx','allocatedCreditLimit':00.00,'pendingTransactionsBalance':0.00,'allocatedCashAdvanceLimit':00.00,'baseCreditLimit':00.00,'outstanding
SettlementBalance':0.00}],'responseCode':'00','responseDesc':'YES','fee':0.00,'balance':0.0
0,'lastDepositAmount':0.00,'ledgerBalance':0.00}}"
}

I want to convert Response into JSON format from string. Everything is in json format except outer inverted commas. Is it any way to convert whole string to json format?

If I use a multiline codec to consume that then

    mutate { gsub => [ "message", "[\r\n]", "" ] }
    mutate { gsub => [ "message", ":00+", ":0" ] }
    json { source => "message" remove_field => [ "message" ] }
    mutate { gsub => [ "Response", "'", '"' ] }
    json { source => "Response" }

works for me.

It is working fine now.

           mutate{
            gsub => ["MethodParameter", "[\r\n  ]", ""]
           }
            mutate{
                gsub => ["MethodParameter", '\"', '"']
            }
            json { 
                source => "MethodParameter"
                target => "MethodParameter_Json"
            }
            mutate{
                remove_field => ["MethodParameter"]
            }
