Convert string in array format to javascript array [duplicate]

Answer 1

Convert the string to a valid json by replacing the single quotes with double quotes and parse:

const str = "['A', 'B', 'C']";

const result = JSON.parse(str.replace(/'/g, '"'));

console.log(result);

Answer 2

The actual solution would be to change the format of your datasource to be valid JSON(" instead of '):

 JSON.parse('["A", "B", "C"]')

However, if that is not an option, you can do that programmaticaly for sure:

JSON.parse("['A', 'B', 'C']".replace(/'/, '"'))

Answer 3

let string = "['A', 'B', 'C']";
JSON.parse(string.replace(/'/g, '"'))

The error with JSON.parse is because JSON requires " and not '
