Without jquery:

function tableToJson() {
  let result = [];
  let table = document.getElementById("print-table").getElementsByTagName("tbody")[0];
  let trs = table.getElementsByTagName("tr");
  for (let i = 2; i < trs.length; i++) {
    let tds = trs[i].getElementsByTagName("td");
    let obj = {};
      obj.name = tds[0].innerHTML;
      obj.rank = tds[1].innerHTML;
      obj.phone = tds[2].innerHTML;
      result.push(obj);
  }
  return JSON.stringify(result);
}
