You could use map

let x = [
  ['Last Name', 'First Name', 'Email Address', 'Role', 'Employee id'],
  ['Smith', 'John', '[email protected]', 'Employee', 'ABC123XYZ'],
  ['Doe', 'Jane', '[email protected]', 'Verifier', 'ABC123XYZ']
]

const [props, ...data] = x

const res = data.map(d => {
  const obj = {}
  d.forEach((value, index) => {
    obj[props[index]] = value
  })
  return obj
})

console.log(res)
