Answer 1

There's a npm package which would perfectly match with your requirements : xlsx . If you need exemple of code, feel free to ask, I often use it

Here is a basic exemple of parsing a xlsx file : I read the value of the cell 'B1' of the first sheet of the file test.xlsx

'use strict';
var XLSX = require('xlsx');
var workbook = XLSX.readFile('test.xlsx');
var sheetName = workbook.SheetNames[0];
var worksheet = workbook.Sheets[sheetName];
var redValue = worksheet['B1'];
console.log(redValue);

我找到了一个使用“kexcel”npm 包读取 excel 的解决方案。我可以用它来完成我的工作。但我卡在了这一点上，我们如何使用它从 excel 中获取最后一行编号。

To read from an excel file you can use 2 different methods,

The first one is using the package xlsx, Inside the project folder run the command 'npm i xlsx' on the terminal which will install the necessary packages

var XLSX = require('xlsx');
var UserCred = XLSX.readFile('ExcelFile/UserLogin.xlsx');
var UserLoginWorksheet= UserCred.Sheets['Sheet1'];
var BaseUrl=UserLoginWorksheet['B1'].v;
console.log(BaseUrl);

Here 'BaseUrl' holds the value at column B1 in the excel file

The second one is using the package exceljs, Inside the project folder run the command 'npm i excel' on the terminal which will install the necessary packages.

var Excel = require("exceljs");
 var filePath = 'ExcelFiles/StaffDetails.xlsx';
 var workbook = new Excel.Workbook();
 await workbook.xlsx.readFile(filePath).then(function () {
 //Use sheetName in getWorksheet function
 worksheet = workbook.getWorksheet("Sheet1");
 let cellValue1 = worksheet.getRow(1).getCell(1).value;
 console.log(emptyCell1+"4");
 })
let  cellValue2 = worksheet.getRow(2).getCell(2).value;

Here cellvalue1 holds A1 columns value and cellvalue2 holds B2 column value
