SheetJS is a library that allows you to work with spreadsheet data in a React application. It supports various file formats such as Excel CSV and other spreadsheet formats. SheetJS enables you to read manipulate and write spreadsheet data directly from your React application. To use SheetJS in React you typically start by installing the library using npm or yarn: npm install sheetjs Once installed you can import SheetJS into your React component and start working with spreadsheet data. Here's a simple example of how you can read an Excel file in a React component using SheetJS: import React from 'react'; import XLSX from 'sheetjs'; const ReadExcelComponent = () => { const handleFileChange = (event) => { const file = event.target.files[0]; 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 = workbook.Sheets[sheetName]; const jsonData = XLSX.utils.sheet_to_json(sheet); console.log(jsonData); }; reader.readAsArrayBuffer(file); }; return ( ); }; export default ReadExcelComponent; In this example we create a simple React component that allows users to upload an Excel file. When a file is selected we use SheetJS to read the file extract the data and convert it to a JSON format for further processing. Please note that SheetJS provides a rich set of features for working with spreadsheet data in React applications making it a valuable tool for handling Excel and other spreadsheet formats within a React environment.
