have a projcet with cjs requires like this :
const express = require("express")
I want to refactor them all to es6 imports :
import express from "express"
in Vscode, in every single file, a 3 dotted line appears under first require, if you press Ctrl+. it will suggest you convert to es6 module
like this 
so repeating this process in all files of a legacy project looks unnecessary, how to convert all files to es6 in Vscode?
any other automated method or editor(other than Vscode like Vim) would be appreciated
