For production use, prefer a CSV parser that handles quoted commas, escaped quotes, and newlines.

const csv = "name,role\nAda,Engineer\nLin,Designer";
const [header, ...lines] = csv.split("\n");
const keys = header.split(",");
const records = lines.map(line => Object.fromEntries(line.split(",").map((value, i) => [keys[i], value])));
console.log(JSON.stringify(records, null, 2));
