使用Node.js和XLSX将Excel数据上传到MySQL数据库时排除日期时间格式错误

我有后端代码，处理数据插入到MySQL数据库从Excel文件，将上传到客户端。代码如下：

const router = require("express").Router();
const fs = require("fs");
const db = require("../config/db");
const multer = require("multer");
const xlsx = require("xlsx");

const upload = multer({ dest: "uploads/" });

// Define route to handle file upload
router.post("/appointments/upload", upload.single("file"), (req, res) => {
  const filePath = req.file.path;
  const workbook = xlsx.readFile(filePath);
  const sheets = workbook.SheetNames;

  let sheetsProcessed = 0; // Variable to keep track of the number of processed sheets

  // Execute the database query to insert data
  sheets.forEach((sheet) => {
    const sheetData = xlsx.utils.sheet_to_json(workbook.Sheets[sheet]);
    const columns = Object.keys(sheetData[0]);
    const values = sheetData.map((row) => columns.map((column) => row[column]));
    const query = `INSERT INTO ${sheet} (${columns.join(", ")}) VALUES ?`;

    db.query(query, [values], (err) => {
      if (err) {
        console.error("Error inserting rows:", err);
        res.status(500).send("Error inserting rows.");
      } else {
        sheetsProcessed++; // Increment the counter for processed sheets

        if (sheetsProcessed === sheets.length) {
          // All sheets have been processed, remove the temporary file and send the response
          fs.unlinkSync(filePath);
          res.send("Data saved successfully!");
        }
      }
    });
  });
});

module.exports = router;

下面是我在Excel中插入的一个示例和数据：

当我尝试上传文件时，它似乎告诉文件内的日期值格式不正确。详情如下：

我尝试将Excel文件中的格式更改为所需的格式：年-月-日分：时：秒
但它仍然产生相同的错误。
谁能告诉我我做错了什么，或者我没有尝试过什么方法来修复它？

您可能需要更改解析文件的方式，而不是文件。
尝试添加{cellDates: true}解析选项：

const sheetData = xlsx.utils.sheet_to_json(workbook.Sheets[sheet], {cellDates: true});

参见文档：
默认情况下，Excel将日期存储为数字，并使用指定日期处理的格式代码。例如，日期19-Feb-17存储为数字42785，数字格式为d-mmm-yy
所有解析器的默认行为都是生成数字单元格。将cellDates设置为true将强制生成器存储日期。
