convert CSV lines into Javascript objects (5 answers)

Closed 6 years ago.

I am javascript noob. I need from csv files to javascript object.

<<1.csv>>
apple
banana
car
<<2.csv>>
apple
banana
<<3.csv>>
apple
car
day
<<4.csv>>
<<5.csv>>
car

I want to get something like this.

x = { "first": ["apple", "banana", "car"],
 "second": ["apple", "banana"],
 "third": ["apple", "car", "day"],
 "fourth": [],
 "fifth": ["car"]
}

What should I do for it?

Answer 1

Below is the sample code.

var x = {};
function readCSV(filename, objectKey) {
 var bufferString; 
 fs.readFile(filename,function (err,data) {
 if (err) {
 return console.log(err);
 }
 //Convert and store csv information into a buffer. 
 bufferString = data.toString();
 //create an array that contains each line as an element
 x[objectKey] = bufferString.split('\n');
 });
}
readCSV('1.csv', 'first');
readCSV('2.csv', 'second');
readCSV('3.csv', 'third');
readCSV('4.csv', 'forth');
readCSV('5.csv', 'fifth');

• EddiGordo: "fs" is not known in this context...
• Swaroop Deval: are you running it on node or browser? If you are running on browser where are you keeping the files? The above code is a sample if you are executing the task on node server. nodejs.org/api/fs.html
