Answer 1

A few methods which come to my mind:

1. Save the excel sheet(s) you want to import in csv format, and then import them into mysql : cf. How to import CSV file to MySQL table By far the simplest method, but you might run into trouble with quotes and commas and other idiosyncrasies.

2. use an javascript excel parser to read the excel file and perform directly with code the update in your mysql database : cf. https://github.com/SheetJS/js-xlsx That option is more complex but it allows you to automate the task should you have many files to copy.

1.Upload the csv file from a form.

2.Include your configuration file.

Take a look at the following code.

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var path = require('path');
var http = require('http');
var formidable = require('formidable');
var fs = require('fs');
var csvParser = require('csv-parse');
var cm = require('csv-mysql');
var connection=require('./config');

// Create application/x-www-form-urlencoded parser
var urlencodedParser = bodyParser.urlencoded({ extended: false })

app.use(express.static('public'));
app.get('/csvupload.html', function (req, res) {
    res.sendFile(path.resolve("../view/csvupload.html"));
})

app.post('/csvfileupload', urlencodedParser, function (req, res) {

    if (req.url == '/csvfileupload') {
        var form = new formidable.IncomingForm();
        form.parse(req, function (err, fields, files) 
        {
            var oldpath = files.filetoupload.path;
            var newpath = 'C:/xampp/htdocs/nodejs/mvc/csvupload/uploads/' + files.filetoupload.name;
            fs.rename(oldpath, newpath, function (err) {
                if (err) throw err;
                res.write('File uploaded and moved!');
                res.end();
            });
            fs.readFile(oldpath, { encoding: 'utf-8' }, function(err, csvData) {

                if (err) 
                {
                    console.log(err);
                }


                csvParser(csvData, { delimiter: ',' }, function(err, data) {
                    if (err)
                    {
                        console.log(err);
                    } 
                    else 
                    {      
                    console.log(data);    
                        var sql = "INSERT INTO customer (id,name,address,designation) VALUES ?";
                        connection.query(sql, [data], function(err) {
                        if (err) throw err;
                        conn.end();
                        });   

                    }
                });
            });
        });

    } 


}).listen(8080);

I have developed a plugin that does this. Here is the link to the npm module: https://www.npmjs.com/package/xlsx-mysql

And the github link: https://github.com/Rizwaan-Company/xlsx-mysql

Sample Code:

const XLSXtoMYSQL = require('xlsx-mysql');

var optionsZ = {
    mysql: {
        host: '127.0.0.1',
        user: 'root',
        database: 'test',
        password: 'password',
        port: '3306'
    },
    csv: {
        delimiter: '+'
    }
}
var locationZ = __dirname + '/file.xlsx';
var waitT = 1000;


XLSXtoMYSQL(locationZ,optionsZ,waitT);
