Is there a function to convert a string to array for Tabulator.js structure data?

Question

I created a Google Application Script that from a sheet generates data for Tabulator.js. As a string. When I copy the text and place it into my html file it works but I load it via Google Appliacation Script call and such string I assign to Tabulator data variable I get an error Data Loading Error - Unable to process data due to invalid data type Expecting: array, Received: string

Is there any simple way to convert such string to needed array of JSON structure? Note the children for the first row. You can play with it in jsFiddle

I tried to use JSON.parse but it looks like the string structure is not good SyntaxError: JSON.parse: expected property name or '}' at line 1 column 2 of the JSON data"

[
  {id:1, name:"BalanceOil", _children:
    [
      {id:2, name:"BalanceOil+  s testy", cena:31},
      {id:3, name:"BalanceOil+ ", cena:31}
    ]
  },
  {id:11, name:"Xtend x2 Kit", cena:23},
  {id:18, name:"Viva+ Kit", cena:21}
]

The original data look like below but I simplified it.

[{id:1, name:"BalanceOil", _children:
    [{id:2, name:"BalanceOil+  s testy", cena:31, mn:1,cena_1:"", package:159, kredityMesicne:4, kredityBalik:14},
     {id:3, name:"BalanceOil+ ", cena:31, mn:1,cena_1:"", package:85, kredityMesicne:4, kredityBalik:8},]},
 {id:11, name:"Xtend x2 Kit", cena:23, mn:1,cena_1:"", package:83, kredityMesicne:3, kredityBalik:8},
 {id:18, name:"Viva+ Kit", cena:21, mn:1,cena_1:"", package:60, kredityMesicne:3, kredityBalik:4}
]

Is it possible to use the source of data as a string or I have to change the code a create the structure as the desired object? What would it actually be? an array or JSON?

Multiple ways to achieve this

1. eval although it could be VERY VERY dangerous if the content passed inside it is not 100% trustworthy as this is simply dynamic code injection/evaluation.

 // from your jsfiddle var asTextOriginal ='[{id:1, name:"BalanceOil", _children:[{id:2, name:"BalanceOil+ s testy", cena:31, mn:1,cena_1:"", package:159, kredityMesicne:4, kredityBalik:14},{id:3, name:"BalanceOil+ ", cena:31, mn:1,cena_1:"", package:85, kredityMesicne:4, kredityBalik:8},]},{id:11, name:"Xtend x2 Kit", cena:23, mn:1,cena_1:"", package:83, kredityMesicne:3, kredityBalik:8},{id:18, name:"Viva+ Kit", cena:21, mn:1,cena_1:"", package:60, kredityMesicne:3, kredityBalik:4}]'; eval(asTextOriginal);

2. manually parse whole string and create array/object out of it: String to object in JS

3. configure the script to return an actual JSON instead string
