How to Parse CSV Data into Arrays Using JavaScript

Reading CSV (Comma-Separated Values) data and converting it into JavaScript arrays can be done with ease.

The CSV Data Format

The given CSV data adheres to the following format:

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
...

Converting to Arrays

To convert this data into an array, you can leverage the $.csv.toObjects() function provided by the jQuery-CSV library. This function automatically maps the CSV data into objects.

Example

For the provided dataset, the code below will generate the desired array:

$.csv.toObjects(csv);

Output

The resulting array will be:

[
  { 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" }
]

Note

• The jQuery-CSV library handles RFC 4180-compliant CSV data, ensuring accuracy.
• Verify that your CSV data contains appropriate line breaks to ensure validity.
