javascript - SheetJS json_to_sheet 重命名标题

Question

我有一个对象数组。默认情况下，sheet_to_json 使用对象键作为 header 。但是，我需要在不显式修改我的对象数组的情况下重命名这些 header 。

这可能吗？

Answer 1

我正在分享我找到的解决方案

// Using same variables as the above answer
var Heading = [
  ["FirstName", "Last Name", "Email"],
];
var Data = [
  {firstName:"Jack", lastName: "Sparrow", email: "abc@example.com"},
  {firstName:"Harry", lastName: "Potter", email: "abc@example.com"},
];

//Had to create a new workbook and then add the header
const ws = XLSX.utils.book_new();
XLSX.utils.sheet_add_aoa(ws, Heading);

//Starting in the second row to avoid overriding and skipping headers
XLSX.utils.sheet_add_json(ws, Data, { origin: 'A2', skipHeader: true });
