Perfect collaboration between Vue and Excel: How to implement batch editing of data

Introduction:
In modern web applications, batch editing of data is an important and complex task. As a popular JavaScript framework, Vue provides a series of powerful tools and features, making perfect collaboration with Excel possible. This article will explore how to use Vue and other related technologies to implement batch editing of data, and give relevant code examples.

1. Data display and import

First, we need to import the data from the Excel spreadsheet into the Vue application and display it to the user. This can be achieved by using Excel.js and the vue-excel-export component provided by the Vue.js community.

In the HTML template, we can use the v-excel command of vue-excel-export to output Excel table data.

<v-excel :data="exportData"></v-excel>

In the Vue instance, we can use the Excel.js library to read the Excel file and store the data in the data property of Vue.

import XLSX from 'xlsx'

export default {
  data() {
    return {
      exportData: []
    }
  },
  methods: {
    handleFileUpload(event) {
      const workbook = XLSX.read(event.target.files[0], { type: 'binary' })
      const worksheet = workbook.Sheets[workbook.SheetNames[0]]
      this.exportData = XLSX.utils.sheet_to_json(worksheet, { header: 1 })
    }
  }
}

2. Editing and saving data

Once the data is imported into the Vue application, we can use Vue's two-way data binding feature to easily edit and save the data.

We can use the v-for and v-model instructions to display each row of data as an editable form.

<template>
  <table>
    <tr v-for="(row, index) in exportData" :key="index">
      <td v-for="(cell, cellIndex) in row" :key="cellIndex">
        <input v-model="exportData[index][cellIndex]" />
      </td>
    </tr>
  </table>
  <button @click="save">保存</button>
</template>

In the Vue instance, we can use the axios library to save the edited data to the server.

import axios from 'axios'

export default {
  methods: {
    save() {
      axios.post('/api/save', this.exportData)
        .then(response => {
          console.log('保存成功！')
        })
        .catch(error => {
          console.error('保存失败：', error)
        })
    }
  }
}

3. Export and download of data

Finally, we need to export the edited data as an Excel file and provide a download function.

We can use the v-excel-download directive of the vue-excel-export component to achieve this function.

<v-excel-download :data="exportData" :filename="'exportData.xlsx'"></v-excel-download>

In the Vue instance, we can use the Excel.js library to convert the data into an Excel file and provide a download link.

import XLSX from 'xlsx'

export default {
  methods: {
    download() {
      const worksheet = XLSX.utils.aoa_to_sheet(this.exportData)
      const workbook = XLSX.utils.book_new()
      XLSX.utils.book_append_sheet(workbook, worksheet, 'Sheet1')
      XLSX.writeFile(workbook, 'exportData.xlsx')
    }
  }
}

Summary:
The perfect collaboration between Vue and Excel makes batch editing of data possible. Through the implementation of functions such as import, edit, save and export, we can greatly improve the efficiency of data management. This article gives relevant code examples, hoping to be helpful to developers who use Vue for batch editing of data.
