How to Convert CSV Data to an Array of JavaScript Objects?

How to Read Data from a CSV File Using JavaScript

Problem:

Convert CSV data into an array of objects, with headings as keys and values as the corresponding values, using JavaScript.

Sample CSV Data:

heading1,heading2,heading3,heading4,heading5
value1_1,value2_1,value3_1,value4_1,value5_1
value1_2,value2_2,value3_2,value4_2,value5_2

Desired Output:

[
    { heading1: value1_1, heading2: value2_1, heading3: value3_1, heading4: value4_1, heading5: value5_1 },
    { heading1: value1_2, heading2: value2_2, heading3: value3_2, heading4: value4_2, heading5: value5_2 },
    ...
]

Solution:

Utilize the jQuery-CSV library, which offers a function called $.csv.toObjects(csv) that automatically maps CSV data to an array of objects.

Steps:

1. Prepare the CSV data: Ensure the data is formatted as valid CSV, with line breaks.
2. Include the jQuery-CSV library: Add to your HTML or JavaScript file.
3. Parse the CSV data: Use the $.csv.toObjects(csv) function to convert the CSV data to an array of objects.

Code:

var data = $.csv.toObjects(csv);

Output:

The data variable will contain an array of objects with headings as keys and values as the corresponding values.

Note:

The original key-value mapping in the output array is technically invalid JavaScript. It should be wrapped in brackets, as shown in the above code example.
