How to use Vue and Excel to implement batch filtering and export of data
In actual project development, we often need to filter and export a large amount of data. As a popular front-end framework, Vue can be used in conjunction with tools such as Excel to quickly and easily implement batch filtering and export of data. This article will introduce how to use Vue and Excel to implement this function, and provide code examples as a reference.
- Preparation
First, we need to install and introduce Vue and related plug-ins and libraries. Relevant installation and usage tutorials can be found in Vue's official documentation. In this article, we will use the Vue CLI to create a basic Vue project. The specific operations are as follows:
1.1 Install Vue CLI:
Enter the following command on the command line to install Vue CLI.
npm install -g @vue/cli
1.2 Create a Vue project:
Enter the following command on the command line to create a new Vue project.
vue create vue-excel-demo
Then follow the prompts to select the default configuration and plug-ins.
1.3 Install the Vue Excel plug-in:
Enter the project directory on the command line and enter the following commands to install the Vue Excel plug-in and related dependencies.
cd vue-excel-demo npm install vue-excel-export xlsx
- Create data table
Create a components folder in the src directory of the project, and create an ExcelTable.vue file under the folder. In the ExcelTable.vue file, we will create a simple data table for displaying and filtering data. The code example is as follows:
<template> <div> <input type="text" v-model="keyword" placeholder="请输入筛选关键字" /> <button @click="filterData">筛选</button> <button @click="exportData">导出</button> <table> <thead> <tr> <th>姓名</th> <th>年龄</th> <th>性别</th> </tr> </thead> <tbody> <tr v-for="item in filteredData" :key="item.id"> <td>{{ item.name }}</td> <td>{{ item.age }}</td> <td>{{ item.gender }}</td> </tr> </tbody> </table> </div> </template> <script> import { export_json_to_excel } from "xlsx"; export default { data() { return { data: [ { id: 1, name: "张三", age: 18, gender: "男" }, { id: 2, name: "李四", age: 20, gender: "女" }, { id: 3, name: "王五", age: 22, gender: "男" } ], keyword: "" }; }, computed: { filteredData() { if (this.keyword === "") { return this.data; } else { return this.data.filter(item => item.name.includes(this.keyword)); } } }, methods: { filterData() { console.log("筛选数据"); // 这里可以进行筛选逻辑的处理 }, exportData() { console.log("导出数据"); const jsonData = JSON.parse(JSON.stringify(this.filteredData)); const worksheet = xlsx.utils.json_to_sheet(jsonData); const workbook = xlsx.utils.book_new(); xlsx.utils.book_append_sheet(workbook, worksheet, "Sheet1"); const excelBuffer = xlsx.write(workbook, { bookType: "xlsx", type: "array" }); const data = new Blob([excelBuffer], { type: "application/octet-stream" }); FileSaver.saveAs(data, "导出数据.xlsx"); } } }; </script>
In the above code, we create a simple data table and use the v-for instruction to loop through the rendering data. At the same time, we use a calculated attribute filteredData to implement the data filtering function and dynamically filter the data based on the entered keywords. The specific logic of the filtering function can be expanded according to actual needs.
- Export data using the Vue Excel plug-in
In the above code, we implement the data export function by clicking the export button. When the user clicks the export button, we first convert the filtered data into Excel's worksheet data structure, and then use the Vue Excel plug-in to export the worksheet data into an Excel file. The code example is as follows:
// 导入相关库 import { export_json_to_excel } from "xlsx"; import FileSaver from "file-saver"; // 导出数据 exportData() { console.log("导出数据"); // 将筛选后的数据转换为Excel的工作表数据结构 const jsonData = JSON.parse(JSON.stringify(this.filteredData)); const worksheet = xlsx.utils.json_to_sheet(jsonData); // 创建并配置Excel工作簿 const workbook = xlsx.utils.book_new(); xlsx.utils.book_append_sheet(workbook, worksheet, "Sheet1"); // 导出Excel文件 const excelBuffer = xlsx.write(workbook, { bookType: "xlsx", type: "array" }); const data = new Blob([excelBuffer], { type: "application/octet-stream" }); FileSaver.saveAs(data, "导出数据.xlsx"); }
In the above code, we first convert the filtered data jsonData into Excel's worksheet data structure worksheet, then create an Excel workbook workbook and add the worksheet into the workbook. Finally, we use the FileSaver library to convert the workbook into an Excel file and save it locally.
- Conclusion
By using Vue and Excel, we can easily implement complex data management and export functions. This article introduces how to use Vue and Excel to implement batch filtering and export of data, and provides specific code examples for readers' reference. I hope this article will be helpful to everyone in actual development.

You can add a function to the Vue button by binding the button in the HTML template to a method. Define the method and write function logic in the Vue instance.

Using Bootstrap in Vue.js is divided into five steps: Install Bootstrap. Import Bootstrap in main.js. Use the Bootstrap component directly in the template. Optional: Custom style. Optional: Use plug-ins.

The watch option in Vue.js allows developers to listen for changes in specific data. When the data changes, watch triggers a callback function to perform update views or other tasks. Its configuration options include immediate, which specifies whether to execute a callback immediately, and deep, which specifies whether to recursively listen to changes to objects or arrays.

There are three ways to refer to JS files in Vue.js: directly specify the path using the <script> tag;; dynamic import using the mounted() lifecycle hook; and importing through the Vuex state management library.

Vue multi-page development is a way to build applications using the Vue.js framework, where the application is divided into separate pages: Code Maintenance: Splitting the application into multiple pages can make the code easier to manage and maintain. Modularity: Each page can be used as a separate module for easy reuse and replacement. Simple routing: Navigation between pages can be managed through simple routing configuration. SEO Optimization: Each page has its own URL, which helps SEO.

Vue.js has four methods to return to the previous page: $router.go(-1)$router.back() uses <router-link to="/" component window.history.back(), and the method selection depends on the scene.

You can query the Vue version by using Vue Devtools to view the Vue tab in the browser's console. Use npm to run the "npm list -g vue" command. Find the Vue item in the "dependencies" object of the package.json file. For Vue CLI projects, run the "vue --version" command. Check the version information in the <script> tag in the HTML file that refers to the Vue file.

There are two main ways to pass parameters to Vue.js functions: pass data using slots or bind a function with bind, and provide parameters: pass parameters using slots: pass data in component templates, accessed within components and used as parameters of the function. Pass parameters using bind binding: bind function in Vue.js instance and provide function parameters.
