如何使用 ExcelJS 读取 xlsx 文件？

Question

How does the code should look like to get cell A1 value from the file "C:\\1.xlsx"? I tried numbers of examples but still didn't managed to get it work.

var Excel = require('exceljs');

var workbook = new Excel.Workbook();

workbook.xlsx.readFile("C:\1.xlsx")
    .then(function() {
        var worksheet = workbook.getWorksheet('Sheet1');
        var cell = worksheet.getCell('A1').value;
        console.log(cell);
    });

I see no errors, but it doesn't work.

Answer 1

You have to access the worksheet first and then the cell. Like this:

var Excel = require('exceljs');
var workbook = new Excel.Workbook();
workbook.xlsx.readFile("C:/1.xlsx")
    .then(function() {
        ws = workbook.getWorksheet("Sheet1")
        cell = ws.getCell('A1').value
        console.log(cell)
    });

Replace "Sheet1" with the real sheet's name. You can also access the worksheet by id.

ws = workbook.getWorksheet(1)

Answer 2

我猜你需要使用getCell().value ，比如：

var cell = worksheet.getCell('C3').value;

Answer 3

await (new Promise((resolve, reject) => {
    var Excel = require('exceljs');
    var workbook = new Excel.Workbook();
    workbook.xlsx.readFile("C:/1.xlsx")
        .then(function() {
            ws = workbook.getWorksheet("Sheet1")
            cell = ws.getCell('A1').value
            console.log(cell)
            resolve()
        });
}));
