How To Generate CSV File For Data

Hello, Guys today we will talk about a popular react library called react-csv. which allows developers to generate CSV files for the user data.

React-csv is a powerful library in the React ecosystem that allows developers to easily handle CSV (Comma Separated Values) files in their applications. This library provides a simple and flexible way to convert data from and to CSV format, making it a great tool for data analysis and visualization.

One of the most useful features of react-csv is its ability to handle both CSV export and import. With just a few lines of code, you can create a CSV file from an array of data and download it to the user’s device.

Here’s an example of how to export data from a React component to a CSV file:

import React from 'react';
import { CSVLink } from 'react-csv';

const data = [
  ['name', 'age', 'email'],
  ['John', '25', 'john@example.com'],
  ['Jane', '30', 'jane@example.com'],
  ['Bob', '28', 'bob@example.com']
];

function MyComponent() {
  return (
    <CSVLink
      data={data}
      filename="my-data.csv"
      className="btn btn-primary"
      target="_blank"
    >
      Export to CSV
    </CSVLink>
  );
}

export default MyComponent;

This will create a CSV file named “my-data.csv” and allow the user to download it from their browser.

The CSVLink component can also be customized with different props such as filename, className, and target.

You can also import data from a CSV file and convert it into JSON or another format you want.

import React, { useState } from 'react';
import { CSVReader } from 'react-papaparse';

function MyComponent() {
  const [data, setData] = useState([]);

  function handleOnDrop(data) {
    setData(data);
  }

  return (
    <CSVReader
      onDrop={handleOnDrop}
      onError={handleOnError}
      addRemoveButton
      config={{ header: true }}
    >
      <span>Drop CSV file here or click to upload.</span>
    </CSVReader>
  );
}

export default MyComponent;

In this example, the CSVReader component accepts a file dropped by the user and converts its contents to an array of data, which is then stored in the component’s state.

React-csv is an easy-to-use library that can greatly simplify the process of working with CSV files in React. Whether you need to export data to a CSV file or import data from one, react-csv has you covered. The library is well-documented and offers a wide range of options to customize the CSV export and import process.

In conclusion, React-csv is a powerful library for handling CSV files in React applications. With the help of this library, developers can easily export and import data in CSV format, making it a great tool for data analysis and visualization. It’s simple to use and provides a lot of options to customize the export and import process as per the requirement.

Extras:: Suppose you want to download the all records list but this time you are not having the whole data and want to do some API call and allow the user to download that data, in that case, we can simply use the ref for this.

// Step : 1  create ref for the csv 
import React, {  useRef } from 'react'

const csvLink = useRef()

// step : 2 -> handle button click event 
<ArrowTooltip title='Download Ads List' arrow placement='top'>
<button className="btn btn-default mr-2 btn-xs p-1 pr-2 pl-2  text-primary "  onClick={downloadAdsList}> 
<i className="fa-solid fa-file-export"  /> 
</button>
</ArrowTooltip>

// now put this code below this button 
 <CSVLink data={csvData} ref={csvLink} filename={"FbAds_List.csv"} headers={tableHeader} >
 </CSVLink>

// handle onClick 
const downloadAdsList = () => {
// api call 
csvLink.current.link.click()
}


Note:: Here header props accept the table header.

With the above approaches, you can easily allow your user to have data in CSV format.
