The combination of Vue and Excel: How to realize automatic filling and export of data

In recent years, Vue, as a lightweight and efficient front-end framework, has been widely used and developed. As a powerful spreadsheet software, Excel is also a tool frequently used by business people and data analysts. This article will introduce how to implement the automatic filling and exporting functions of data in Vue, so that the two swords of Vue and Excel can be combined to improve the efficiency of data processing.

1. Automatic filling of data

In actual development, we often encounter the need to generate a large amount of data based on some rules. Vue's data binding feature can easily realize automatic filling of data. The following is a sample code:

<template>
  <div>
    <input v-model="startNum" type="number" placeholder="请输入起始数值">
    <input v-model="step" type="number" placeholder="请输入步长">
    <button @click="generateData">生成数据</button>
    <ul>
      <li v-for="item in dataList" :key="item">{{ item }}</li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      startNum: 0, // 起始数值
      step: 1, // 步长
      dataList: [] // 数据列表
    };
  },
  methods: {
    generateData() {
      this.dataList = []; // 清空数据列表
      for (let i = this.startNum; i <= 100; i += this.step) {
        this.dataList.push(i);
      }
    }
  }
};
</script>

In the above example, by entering the starting value and step size, and clicking the button, a data list that conforms to the rules will be automatically generated. Using Vue's data binding, the data list will be updated in real time every time the starting value and step size are input.

2. Export of data

In practical applications, we usually need to export the generated data to Excel for further processing. The following is a sample code to implement the data export function:

<template>
  <div>
    <button @click="exportData">导出数据</button>
  </div>
</template>

<script>
export default {
  methods: {
    exportData() {
      const worksheet = XLSX.utils.json_to_sheet(this.dataList);
      const workbook = XLSX.utils.book_new();
      XLSX.utils.book_append_sheet(workbook, worksheet, "Sheet1");
      XLSX.writeFile(workbook, "data.xlsx");
    }
  }
};
</script>

In the above example, we used the xlsx library to implement the data export function. When you click the Export Data button, an Excel file named "data.xlsx" will be generated, which contains the data list we generated.

It is worth noting that we need to first convert the data list into a data structure suitable for Excel format through the json_to_sheet method, then add the data structure to the workbook, and finally call writeFile method exports the workbook to an Excel file.

Through the above two examples, we can easily implement the automatic filling and exporting of data in Vue. Using Vue's data binding features and the support of the xlsx library, we can process large amounts of data more efficiently and quickly export the results to Excel for further analysis and processing.

Summary:

This article introduces how to implement automatic filling and exporting of data in Vue. Through the support of Vue's data binding and xlsx library, we can process large amounts of data more efficiently and export the results to Excel for further analysis and processing. This two-pronged approach can improve the efficiency of data processing and bring more convenience to our work and study.
