Is it still possible to parse JSON files into Arrays?
I believe you need to create a JSON object to store the JSON parse data. var json = JSON.new() var error = json.parse(json_string) First line creates a JSON object, second one parses and stores any errors in the variable error. Then you can access the data using json.data. Or you could just skip the whole JSON and just write your dialogue straight into a dict in a gdscipt file. You could also check out the Dialogic plugin for Godot. You can handle dialogue trees in the editor. More on reddit.com

I made it that way:
if I have:
var jsonArg1 = new Object();
jsonArg1.name = 'calc this';
jsonArg1.value = 3.1415;
var jsonArg2 = new Object();
jsonArg2.name = 'calc this again';
jsonArg2.value = 2.73;
var pluginArrayArg = new Array();
pluginArrayArg.push(jsonArg1);
pluginArrayArg.push(jsonArg2);
to convert pluginArrayArg (which is pure javascript array) into JSON array:
var jsonArray = JSON.parse(JSON.stringify(pluginArrayArg))

Use JSON.parse and then reduce to get what you want,
var s = `[{"role":"noi_user"},{"role":"bert_user"}]`
var arr = []
try {
arr = JSON.parse(s).reduce((acc, val)=>[...acc, val.role], [])
} catch (e){
console.log("Invalid json")
}
console.log(arr) 2 of 4

Is this what you are loking for ? You can map on your array and just extract the role attribute of each datum.
const jsonString = ...
const data = JSON.parse(jsonString).map(data => data.role);
console.log(JSON.stringify(data, null, 2));
JSON uses double quotes to delimit strings and field names.
