How to remove double quote in broken nested json values?

Question

Am stuck with applying replace() with regex for broken nested json value. For example, i want to remove doublequote for origin value below.

How to change from this:

{
 "type" : "fruitList",
 "data" : [{
   "fruitName" : "test",
   "origin" : "[{"states" : "USA"}]"
 }]
}

To this:

{
 "type" : "fruitList",
 "data" : [{
   "fruitName" : "test",
   "origin" : [{"states" : "USA"}]
 }]
}

You could simply use 2 replace without RegEx:

jsonstring.replace('"[', "[").replace(']"', "]")

Or if you just want to use a single replace with RegEx:

jsonstring.replace(/("\[|\]")/g, match => {
   return match === '"[' ? "[" : "]"
})
