How to Read CSV Data in JavaScript and Convert it to an Array

Problem:

You have CSV data with multiple columns. How do you read this data using JavaScript and convert it into an array where each object represents a row with key-value pairs?

Example 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 Array:

[
    { 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:

Using the jQuery-CSV library, you can easily convert the CSV data into an array of objects:

Step 1: Add Line Breaks

Ensure that your CSV data has line breaks to make it valid.

Step 2: Use the $.csv.toObjects() Function

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

Output:

The data variable will contain an array of objects representing the rows in the CSV data, with key-value pairs for the headings and their corresponding values.

Note: For more flexibility and compatibility, the jQuery-CSV library is recommended over the code sample you provided.
