What is react-csv?

The react-csv package is a simple and powerful library for handling CSV (Comma-Separated Values) files in React applications. It allows you to easily generate and download CSV files directly from your React components.

What are react-csv's main functionalities?

Download CSV

This feature allows you to create a link that, when clicked, will generate and download a CSV file with the provided data. The CSVLink component takes in the data and filename as props.

import { CSVLink } from 'react-csv';

const data = [
  { firstname: 'John', lastname: 'Doe', email: 'john.doe@example.com' },
  { firstname: 'Jane', lastname: 'Doe', email: 'jane.doe@example.com' }
];

const DownloadCSV = () => (
  <CSVLink data={data} filename={"my-file.csv"}>
    Download me
  </CSVLink>
);

Export CSV

This feature allows you to programmatically trigger a CSV file download. The CSVDownload component can be used to immediately start the download when the component is rendered.

import { CSVDownload } from 'react-csv';

const data = [
  { firstname: 'John', lastname: 'Doe', email: 'john.doe@example.com' },
  { firstname: 'Jane', lastname: 'Doe', email: 'jane.doe@example.com' }
];

const ExportCSV = () => (
  <CSVDownload data={data} target="_blank" />
);

Custom Headers

This feature allows you to define custom headers for your CSV file. The headers prop takes an array of objects, each containing a label and a key, which maps to the data fields.

import { CSVLink } from 'react-csv';

const headers = [
  { label: 'First Name', key: 'firstname' },
  { label: 'Last Name', key: 'lastname' },
  { label: 'Email', key: 'email' }
];

const data = [
  { firstname: 'John', lastname: 'Doe', email: 'john.doe@example.com' },
  { firstname: 'Jane', lastname: 'Doe', email: 'jane.doe@example.com' }
];

const CustomHeadersCSV = () => (
  <CSVLink data={data} headers={headers} filename={"custom-headers.csv"}>
    Download with Custom Headers
  </CSVLink>
);
