To render an xlsx file inside an iframe in a React.js application, you can use the following steps:

  1. Install the xlsx library from npm by running the following command:
1
npm install xlsx


  1. Import the xlsx library in your React component file:
1
import * as XLSX from 'xlsx';


  1. Create a function to read the xlsx file and convert it to a data URL:

const renderXlsxFile = (file) => {
  const reader = new FileReader();
  reader.onload = (e) => {
    const data = new Uint8Array(e.target.result);
    const workbook = XLSX.read(data, { type: 'array' });
    const sheetName = workbook.SheetNames[0];
    const sheet = XLSX.utils.sheet_to_html(workbook.Sheets[sheetName]);
    
    const iframe = document.getElementById('xlsx-iframe');
    iframe.srcdoc = sheet;
  };

  reader.readAsArrayBuffer(file);
};


  1. Create an iframe element in your component's render method:

return (
  <div>
    <input type="file" onChange={(e) => renderXlsxFile(e.target.files[0])} />
    <iframe id="xlsx-iframe" width="100%" height="400px"></iframe>
  </div>
);


  1. Add CSS styles to your component to make the iframe visible:

#xlsx-iframe {
  border: 1px solid #ccc;
  margin-top: 10px;
}


By following these steps, you should be able to render an xlsx file inside an iframe in your React.js application.
