How to Render Xlsx Inside Iframe In React.js?

To render an xlsx file inside an iframe in a React.js application, you can use the srcdoc attribute of the <iframe> element to populate it with the Excel file content.

First, you need to convert the xlsx file content into a base64 encoded string. You can do this using a library like xlsx or file-saver. Once you have the base64 encoded string, you can set it as the srcdoc attribute value of the iframe element.

Here is a basic example of how you can achieve this in React.js:

import React from 'react';

const ExcelViewer = ({ excelContent }) => {
  const base64EncodedContent = btoa(String.fromCharCode.apply(null, new Uint8Array(excelContent)));

  return (
    <iframe
      width="100%"
      height="500"
      src={`data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,${base64EncodedContent}`}
      frameBorder="0"
    ></iframe>
  );
}

export default ExcelViewer;

In the above code snippet, the ExcelViewer component takes the base64 encoded content of the xlsx file as a prop and renders an iframe with the xlsx content displayed inside.

Remember to handle any error cases and additional styling as needed for your specific use case.

3

const arrayBuffer = /* ArrayBuffer of the xlsx content */;
const data = new Blob([arrayBuffer], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' });
const url = URL.createObjectURL(data);

What is the most efficient method to display xlsx files in an iframe in React?

One efficient method to display xlsx files in an iframe in React is to use the react-iframe library. This library allows you to easily embed an iframe into your React component and specify the URL of the xlsx file you want to display.

Here's an example of how you can display an xlsx file in an iframe using the react-iframe library:

1. Install the react-iframe library using npm or yarn:

1

npm install react-iframe

or

1

yarn add react-iframe

1. Import the Iframe component from the react-iframe library in your React component:

1

import Iframe from 'react-iframe';

1. Use the Iframe component in your React component and specify the URL of the xlsx file you want to display:

function App() {
  return (
    <Iframe
      url="https://example.com/file.xlsx"
      width="100%"
      height="500px"
      id="myId"
      className="myClassname"
      display="initial"
      position="relative"
      allowFullScreen
    />
  );
}

In this example, the Iframe component is used to display the xlsx file located at https://example.com/file.xlsx in an iframe with a width of 100% and a height of 500px.

This method is efficient because it leverages the react-iframe library, which simplifies the process of embedding iframes in React components and allows you to easily display xlsx files in an iframe with minimal configuration.

Here's an example of how you can achieve this:

1. Install the xlsx library using npm or yarn:

1

npm install xlsx

1. Import the xlsx library in your React component:

const reader = new FileReader();

reader.onload = (e) => {
  const data = e.target.result;
  const workbook = XLSX.read(data, { type: 'binary' });
  const base64data = btoa(XLSX.write(workbook, { bookType: 'xlsx', type: 'base64' }));
  
  // set the base64 string to the state or pass it to the iframe src attribute
};

reader.readAsBinaryString(file);

1. Display the xlsx file in an iframe:

1

<iframe src={`data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64,${base64data}`} width="100%" height="500px"></iframe>

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

How to load an xlsx file in an iframe using React.js?

To load an xlsx file in an iframe using React.js, you will first need to import the xlsx file and then embed it within an iframe component. Below is an example code snippet to achieve this:

const XlsxFile = () => {
  const xlsxFileUrl = 'path-to-your-xlsx-file';

  return (
    <iframe
      src={xlsxFileUrl}
      width="100%"
      height="500"
    />
  );
};

export default XlsxFile;

In the above code, replace 'path-to-your-xlsx-file' with the URL or file path of your xlsx file. This component will render an iframe that loads and displays the xlsx file on the webpage.

Make sure to set the correct width, height, and any other required attributes for the iframe based on your requirements.

You can then include this XlsxFile component in your React application to load the xlsx file in an iframe.
