Answer 1

var admin = require('firebase-admin');

var serviceAccount = require('./serviceAccountKey.json');

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: 'https://csvread-d149c.firebaseio.com'
});

const csv = require('csv-parser');  
const fs = require('fs');

const firestore = admin.firestore();

// CSV FILE data.csv

// Name,Surname,Age,Gender
// John,Snow,26,M  
// Clair,White,33,F  
// Fancy,Brown,78,F

fs.createReadStream('data.csv')  
  .pipe(csv())
  .on('data', (row) => {
    console.log(row);
    if(row) {
      firestore.collection('csv').add({
        name: row.Name,
        surname: row.Surname,
        age: row.Age,
        sex: row.Gender
      });
    }
    else {
      console.log('No data')
    }
  })
  .on('end', () => {
    console.log('CSV file successfully processed');
  });
