What if { "Id": "parent", "Function": "Project Management", "Phase": "" } or { "Id": "parent", "Function": "Project Management", "Phase": null}? — Mamun

You can do it like this:

data = data.map(obj => Object.keys(obj).reduce((prev, prop) => {
  // you can check for '(Null)', null or for any different kind of value here
  if (obj[prop] != '(Null)') {
    prev[prop] = obj[prop]
  }
  return prev
}, {}))

Also You can do as : data.forEach((d, v)=> { for(x in d) { if(d[x] == "(Null)") { delete d[x] }; }});
