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

Posted on February 14, 2023

 

 

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

 

 

JavaScript

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.
