`
myForm.addEventListener("submit", function (e) {
e.preventDefault();
const input = csvFile.files[0];
const reader = new FileReader();

  reader.onload = function (e) {
    const text = e.target.result;
    const data = csvToArray(text);
    document.write(JSON.stringify(data));
  };
  
  reader.readAsText(input);
});

`

how can I get data from outside for use it in anover functions as Parameter?

Hello - I appreciate your work on this. Do you know how I might be able parse a file that's sitting in a directory on a server? Your code allows the user to add a file but I would need to parse from a file that's not uploaded manually. Thank you

My source CSV has values that contain commas. Every value has double quotes around it. How would I change this code to skip the commas that are inside of double quotes?

Code example:
ID,Full Name,Address
"85DD-019F","Alice","123 Park Ave, Topeka, KS, 66618"

I've tried setting the delimiter to '/,(?=(?:(?:[^"]*"){2})*[^"]*$)/' (from this link) but then the array is the entirety of the row, then a bunch of undefined to fill out the rest of the values.

Hi Nathan,

Thanks for your excellent code. I am using it to read a CSV into my app from google sheets.

My issue is some of my fields have double quotes put around them by google sheets because the actual field contains commas.

e.g.

field1, "field 2, more field2, even more field2", field3

This seems to break the code somewhere in here I guess:

const values = row.split(delimiter);
const el = headers.reduce(function (object, header, index) {
object[header] = values[index];

Any ideas which bit is breaking? I guess it must be the 'split' function??

I'm a very average javascript coder :)

Thanks much!
