Node.js Tutorial to Detect or Validate Whether a String is CSV or Not Using detect-csv Library in Command Line

Welcome folks today in this blog post we will be detecting or validating whether a given string is csv or not using detect-csv library in command line. All the full source code of the application is shown below.

Get Started

In order to get started you need to install the below library using the below command

npm i detect-csv

After that you need to make a index.js file and copy paste the following code

index.js

var detect = require('detect-csv')
 
var csv = detect('a,b,c\n1,2,3')
 
console.log(csv.delimiter)
console.log("ds"+csv.newline)
// prints ',' and '\n'
 
var isCsv = detect('notacsv')
console.log('This is ' + (csv ? '' : 'not') + ' a csv')

var detect = require('detect-csv')

var csv = detect('a,b,c\n1,2,3')

console.log(csv.delimiter)

console.log("ds"+csv.newline)

// prints ',' and '\n'

var isCsv = detect('notacsv')

console.log('This is ' + (csv ? '' : 'not') + ' a csv')

As you can see we are importing the library at the top and then we are passing the given string to the method and detecting whether this is a valid csv or not. And also we are finding out the delimiter of the given string.
