convert-to-csv v1.0.5

Convert to CSV

This package provides a utility function to convert an array of objects into a CSV format, suitable for exporting data from JavaScript applications.

Installation

You can install this package via npm:

npm install convert-to-csv

Usage

First, import the convertToCSV function from the 'convert-to-csv' package:

import { convertToCSV } from 'convert-to-csv';

Example :

Let's say you have an array of user objects like this:

const users = [
  {
    name: 'Ashutosh',
    email: 'example@example.com',
    address: { city: 'Lucknow', postalCode: 226010, state: 'UP' },
  },
  {
    name: 'Yuvaraj',
    email: 'example@gmail.com',
    address: { city: 'Varanasi', postalCode: 226016, state: 'UP' },
  },
];

To download this data into a CSV file, you can use the convertToCSV function:

convertToCSV({ data: users });

Download CSV with a Custom File Name

If you want to specify a custom file name for the downloaded CSV file, you can pass it as an option to the convertToCSV function:

convertToCSV({data : users, name="mycsvfile" })

This will download the CSV file with the name "mycsvfile.csv".

Download CSV with a Custom Headers

You can also provide custom headers for the CSV file by passing an array of strings to the header option. Here's how you can use it:

const customHeaders = ['Name', 'Email', 'City', 'Postal Code', 'State'];

convertToCSV({ data: users, header: customHeaders, name: 'custom_csv' });

The downloaded CSV file will have the specified custom headers.

Explanation

The convertToCSV function takes an object as its parameter with the following properties:

• data: An array of objects that you want to convert to CSV format.
• name (optional): A string representing the custom file name for the downloaded CSV file. If not provided, it defaults to "download.csv".
• header (optional): An array of strings representing custom headers for the CSV file. If provided, these headers will be used instead of deriving them from the keys of the objects in the array.

When you call convertToCSV, it converts the array of objects into CSV format and initiates a download of the CSV file.

The CSV file will have headers either derived from the keys of the objects in the array or from the provided header array, and each object's properties will be listed as values in the corresponding columns.

If a custom file name is provided, the downloaded CSV file will have that name; otherwise, it will default to "download.csv".
