Convert array of strings to array of objects in JSON property

I have the following JSON returned from an endpoint

{
    "response": {
        "lines": [
            "[{'line':'3007621h7s2','type':'national'},{'line':'3007663f7s9','type':'international'}]",
            "[{'line':'3007262p7f6','type':'national'},{'line':'3007262a0s1','type':'international'}]"
        ]
    }
}

the property lines is an array that should contain multiple arrays, however, as you can see, lines is an array of strings. How can I make each element in the lines property to be an array of objects?

Thanks

The easiest way to convert the strings to arrays is to eval() them.

var obj = {
  "response": {
    "lines": [
      "[{'line':'3007621h7s2','type':'national'},{'line':'3007663f7s9','type':'international'}]",
      "[{'line':'3007262p7f6','type':'national'},{'line':'3007262a0s1','type':'international'}]"
    ]
  }
}

obj.response.lines = obj.response.lines.map(line => eval(line));

console.log(obj);

There are a couple of errors with your json (I dont know if that is the actual json or it was hardcoded so you might check it). The first one is

  • 'line:'3007621h7s2 should be 'line':3007621h7s2
  • Values like 3007621h7s2 should be '3007621h7s2'

When you fix your json, then you can use JSON.parse() to convert the string

var data = {
    "response": {
        "lines": [
            "[{'line':'3007621h7s2', 'type': 'national'},{'line':'3007663f7s9','type':'international'}]",
            "[{'line':'3007262p7f6', 'type': 'national'},{'line':'3007262a0s1','type':'international'}]"
        ]
    }
}

data.response.lines = data.response.lines.map(a=>JSON.parse(a.replace(/'/g,'"')))

console.log(
  data
)
