Question

With nodejs I want to parse a .csv file of 10000 records and do some operation on each row. I tried using http://www.adaltas.com/projects/node-csv. I couldnt get this to pau

Answer 1

• This solution uses csv-parser instead of csv-parse used in some of the answers above.
• csv-parser came around 2 years after csv-parse.
• Both of them solve the same purpose, but personally I have found csv-parser better, as it is easy to handle headers through it.

Install the csv-parser first:

npm install csv-parser

So suppose you have a csv-file like this:

NAME, AGE
Lionel Messi, 31
Andres Iniesta, 34

You can perform the required operation as:

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

fs.createReadStream(inputFilePath)
.pipe(csv())
.on('data', function(data){
    try {
        console.log("Name is: "+data.NAME);
        console.log("Age is: "+data.AGE);

        //perform the operation
    }
    catch(err) {
        //error handler
    }
})
.on('end',function(){
    //some final operation
});
