如何在 excel4node 中打印 json 数组

Question

我必须打印 10000 行的 excel。有什么方法可以使用 excel4node?.

批量打印 json 数组

例如：Mongodb insertMany操作

Answer 1

为此，您可以创建一个将 json 作为输入的函数，并在函数内部对其进行迭代。因此，如果您想要的话，您将能够将您的操作视为单个操作。

Answer 2

我从 npm 作者那里找到了要点。似乎已经不可能了

这是例子：

const xl = require('excel4node');

// Create workbook and add worksheet
const wb = new xl.Workbook();
const ws = wb.addWorksheet('Data', {
  disableRowSpansOptimization: true,
});

// Generate some fake data for testing
const data = [];
const rowCount = 50000;
let row = 1;
while (row <= rowCount) {
  data.push({
    zone_name: `zone_name_${row}`,
    circle_name: `circle_name_${row}`,
    div_town_name: `div_town_name_${row}`,
    tender_name: `tender_name_${row}`,
    tkc_name: `tkc_name_${row}`,
    work_name: `work_name_${row}`,
    material_name: `material_name_${row}`,
    insert_dttm: new Date(),
    app_fname: `app_fname_${row}`,
    ins_fname: `ins_fname_${row}`,
  });
  row += 1;
}

const startRow = 4;
// Add data to worksheet
if (data.length) {
  data.forEach((item, i) => {
    const currentRow = i + startRow;
    const newtarget = 'newtarget';
    const newprogress = 'newprogress';

    ws.cell(currentRow, 1).number(i).style({
      alignment: {
        vertical: ['center'],
        horizontal: ['left']
      },
