Json formatting to remove \n and \ before and after json attribute in apigee proxy response

[LakshmiPavitra]

This is small snippet :

{
"content": "[\n {\n \"gmb_code\": INDINDIND\",\n \"reputation_name\": \"Some Hospitalname\"]"
}

But I need it to be without \ and \n  like below

{

 "gmb_code" : "INDINDIND",

"reputation_name": "Some Hospitalname"
}
