greetings, given any csv data how can one get an array dynamically mapped to key(column_name) value(row_value)? example csv

name,age,salary
jo,32,40000
jane,27,50000

name,age,salary
jo,32,40000
jane,27,50000

result

[
{name: jo, age: 32, salary: 40000},
{name: jane, age: 27, salary: 27,50000}
]

[
{name: jo, age: 32, salary: 40000},
{name: jane, age: 27, salary: 27,50000}
]

Gracias!

d3.csv does this automagically.

diving in step 1

let url = 'https://raw.githubusercontent.com/plotly/datasets/master/3d-scatter.csv';

(async () => {
    let data = await fetch(url);
    let response = await data.text();
    console.log('response', response);
    return response;
})();

let url = 'https://raw.githubusercontent.com/plotly/datasets/master/3d-scatter.csv';

(async () => {
    let data = await fetch(url);
    let response = await data.text();
    console.log('response', response);
    return response;
})();

found this. will clean it up and voila

const CSVToJSON = (data, delimiter = ',') => {
    const titles = data.slice(0, data.indexOf('\n')).split(delimiter);
    return data
      .slice(data.indexOf('\n') + 1)
      .split('\n')
      .map(v => {
        const values = v.split(delimiter);
        return titles.reduce(
          (obj, title, index) => ((obj[title] = values[index]), obj),
          {}
        );
      });
  };

const CSVToJSON = (data, delimiter = ',') => {
    const titles = data.slice(0, data.indexOf('\n')).split(delimiter);
    return data
      .slice(data.indexOf('\n') + 1)
      .split('\n')
      .map(v => {
        const values = v.split(delimiter);
        return titles.reduce(
          (obj, title, index) => ((obj[title] = values[index]), obj),
          {}
        );
      });
  };
