I have a JSON file with date format in the form of
2021-09-21 15:37:29.590 +03:00.
How can we convert it to a Date in a T-Z Format ?
You can pass it into the Date constructor and call toISOString.
const convert = (dateString) => new Date(dateString).toISOString();
console.log(convert('2021-09-21 15:37:29.590 +03:00')); // 2021-09-21T12:37:29.590Z
