Question

我有一个对象数组。默认情况下，sheet_to_json使用对象键作为标题。但是，我需要重命名这些标头，而无需显式修改我的对象数组。

这可能吗？

Answer 1

在下面替换最后一行。

XLSX.utils.sheet_add_json(ws, data, {skipHeader: true, origin: "A2"});

Answer 2

我解决了这个问题，因为上述两种方法都不适合我

let EXCEL_EXTENSION = '.xlsx';
     let worksheet: XLSX.WorkSheet;
     let customHeader = true;
      let sheetName = 'My Sheet 1';  
      
    if (customHeader) {  
     const headers: any = { Cust: 'Customer Name', Addr1: 'Address 1' };
    this.data.unshift(headers); // if custom header, then make sure first row of data is custom header 
      worksheet = XLSX.utils.json_to_sheet(json, { skipHeader: true });
    } else {
      worksheet = XLSX.utils.json_to_sheet(json);
    }
    const workbook = XLSX.utils.book_new();
    const fileName =  'myExcelFile_Export_' + moment().format('MM-DD-YYYY_hh:mm:ss').toString() + EXCEL_EXTENSION;
    XLSX.utils.book_append_sheet(workbook, worksheet, sheetName);
    XLSX.writeFile(workbook, fileName);

Answer 3

我正在分享找到的解决方案

// 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 });

Answer 4

您可以使用XLSX.utils.aoa_to_sheet添加标题。

例如：

// Do mind! it is array of array
var Heading = [
  ["FirstName", "Last Name", "Email"],
];
var Data = [
  {firstName:"Jack", lastName: "Sparrow", email: "abc@example.com"},
  {firstName:"Harry", lastName: "Potter", email: "abc@example.com"},
];
var ws = XLSX.utils.aoa_to_sheet(Heading);
XLSX.utils.sheet_add_json(ws, Data);

Answer 5

这对我有用：

var wb = XLSX.utils.book_new();

        var ws = XLSX.utils.json_to_sheet(json_data, { origin: 'A2', skipHeader: true });
        XLSX.utils.sheet_add_aoa(ws, headings); //heading: array of arrays

        XLSX.utils.book_append_sheet(wb, ws);


        XLSX.writeFile(wb, filename + '.xlsx')

SheetJS json_to_sheet重命名标头
