How to Parse CSV File in Javascript?

To convert or parse CSV data into an array , you need to use JavaScript's FileReader class, which contains a method called readAsText() that will read a CSV file content and parse the results as string text. Once you have the string , you can create a custom function to turn the string into an array

parse csv javascript

//Suppose you have a CSV file data.csv which contains the data:

//Daffy Duck,24
//Bugs Bunny,22

const csv = require('csv-parser')
const fs = require('fs')
const results = []; 

  .on('data', (data) => results.push(data))
  .on('end', () => console.log(results));

 // [{ NAME: 'Daffy Duck', AGE: '24' },
//   { NAME: 'Bugs Bunny', AGE: '22' } ] 

This is a fully configurable, tested, and optimized CSV parser using the jQuery syntax. We can use the csv.toArrays() function to load data into an array.

array = $.csv.toArrays(csv, {
  delimiter: "'", 
  separator: ';', // Sets a custom field separator character
