Tips for implementing Papa Parse to parse CSV files using JavaScript

I've been exploring their API without much luck.

My goal is to extract data from CSV files that are sent to the client upon server entry.

Here's the code snippet I attempted:

// Attempting to parse local CSV file
Papa.parse("data/premier league/14-15s.csv", {
    complete: function(results) {
        console.log("Finished:", results.data);
    }
});

This approach didn't yield any results, as shown by the following output:

Finished: [Array[1]]
0: Array[1]
  0: "data/premier league/14-15s.csv"
  length: 1
__proto__: Array[0]
length: 1
__proto__: Array[0]
(Various Array functions listed)

The question remains: Where is the actual CSV data?

Answer №1

Even though this question was asked months ago, it seems like I've encountered a similar issue and managed to figure it out. I wanted to share my potential solution in case other beginners, like myself, come across this problem.

It appears that you are attempting to use papa parse to read a CSV file on your local machine using a file path. To do this according to the documentation on the papa parse website, it should look something like this:

Papa.parse(url, {
    download: true,
    // additional configuration...
});

Based on my understanding, it seems like you may be missing the download: true argument as the second parameter. The documentation states that the url can also be a file path - just like the one you have provided. While I'm relatively new to coding, having started around 2 months ago, I hope this suggestion could potentially assist others facing a similar confusion!

Answer №2

When trying to parse a string containing data/premier league/14-15s.csv, make sure you are not attempting to parse a remote CSV file instead of a local one. Refer back to the documentation for clarification on this matter. To parse a local CSV file, you need to provide a File object that originates from an <input type="file"> element.
