parse csv in javascript

To parse a CSV file in JavaScript, you can use the "papaparse" library. Here is an example of how to use it:

index.tsx
// Importing papaparse library
import Papa from 'papaparse'

// CSV String to be parsed
const csvString = 'Name, Age, Country\nJohn, 25, USA\nMary, 31, Canada\n'

// Parsing the CSV
const { data, errors } = Papa.parse(csvString)

// Checking for errors
if (errors.length > 0) {
  console.error(errors)
} else {
  console.log(data)
}
333 chars
16 lines

In the above code, we first import the papaparse library. Then we define a CSV string that we want to parse. We use the Papa.parse() method to parse the CSV string. This method returns an object that contains two properties: data and errors. The data property contains the parsed CSV data as an array of arrays. Each inner array represents a row in the CSV. The errors property contains an array of any errors that may have occurred during parsing.

Finally, we check if there are any errors and log the parsed data to the console.
