methods:{
// Export EXCEL file method download() {
// Get userlist data from the data attribute of the Vue component const data = ;
// Convert JSON format data into worksheets (worksheet) // The .json_to_sheet() method accepts an array where each element is an object representing a line in Excel // The data variable here should be an array, and each object in the array contains the row data to be written to Excel const worksheet = .json_to_sheet(data);
// Create a new workbook (workbook) // Workbooks are top-level containers in Excel files that can contain multiple worksheets const workbook = .book_new();
// Add worksheet to workbook // 'Sheet1' is the name of the worksheet, you can modify it as needed .book_append_sheet(workbook, worksheet, 'Sheet1');
// Save the workbook as an Excel file and trigger the download // '' is the exported file name, you can modify it as needed // This method will generate a .xlsx file and prompt the user to download it (workbook, '');
},
}
}
</script>Step 1: InstallxlsxLibrary
First, you need to install it in your Vue projectxlsxlibrary. Open the terminal, go to your project directory, and run the following command:
npm install xlsx --save
This will installxlsxlibrary and its dependencies and add them to your project.
Step 2: Prepare the data
In Vue components, you need to prepare the data you want to export. This data can be responses from the API, data in local state management (such as Vuex), or any other data source. Typically, this data is organized in an array, where each object represents a row in Excel and the keys of the object represent the column title.
For example, suppose we have the following data:
const data = [
{ name: 'Zhang San', age: 20, gender: 'male' },
{ name: 'Li Si', age: 25, gender: 'female' },
{ name: 'Wang Wu', age: 30, gender: 'male' }
];Step 3: Create an export method

import * as XLSX from 'xlsx';
export default {
methods: {
exportToExcel() {
// Convert data to worksheets const worksheet = .json_to_sheet();
// Create a workbook and add a worksheet const workbook = .book_new();
.book_append_sheet(workbook, worksheet, 'Sheet1');
// Export Excel file (workbook, '');
}
}

<template>
<div>
<button @click="exportToExcel">Export asExcel</button>
