React Js Convert JSON to CSV File

React Js Convert JSON to CSV File:React JS can convert JSON to a CSV file by first processing the JSON data and transforming it into a comma-separated value format. This involves iterating through the JSON objects, extracting values, and structuring them as rows in the CSV.

Build the CSV string and create a download link with the Blob API. Handle data formatting and escaping to ensure CSV validity. Update your component's state to trigger re-renders when needed. Remember to handle edge cases like empty values.

How can I use Reactjs to efficiently convert a JSON object into a CSV file?

This ReactJS code snippet demonstrates how to convert JSON data into a CSV file. It defines a component that holds JSON data containing names, ages, and cities. Upon clicking a button, the code converts the JSON data into CSV format and triggers a download. The CSV content is constructed by mapping JSON values, joining them with commas, and then combining lines with line breaks. The encoded CSV content is linked to a downloadable anchor element, and after clicking, the link is removed

  <script type="text/babel">
    const { useState } = React;
    const jsonData = [
      { name: 'John', age: 28, city: 'New York' },
      { name: 'Jane', age: 24, city: 'Los Angeles' },
    ];
    const App = () => {
      const convertToCSV = () => {
        const csvContent = "data:text/csv;charset=utf-8," +
          jsonData.map(item => Object.values(item).join(',')).join('\n');

        const encodedUri = encodeURI(csvContent);
        const link = document.createElement('a');
        link.setAttribute('href', encodedUri);
        link.setAttribute('download', 'data.csv');
        document.body.appendChild(link); // Required for Firefox
        link.click();
        document.body.removeChild(link); // Clean up the link element
      };

      return (
        <div className='container'>
          <h3>React Js Convert JSON Datato CSV file</h3>
          <button onClick={convertToCSV}>Convert to CSV</button>
        </div>
      );
    }

    ReactDOM.render(<App />, document.getElementById("app"));
