Intelligent splicing of Vue and Excel: How to realize automatic modification and export of data

Introduction:
In work and study, we often need to process a large amount of data, and Excel, as a powerful Spreadsheet software has become one of our most commonly used tools. Now, with the rapid development of front-end technology, we can use the powerful functions of the Vue framework to intelligently splice with Excel to realize automatic modification and export of data, which greatly improves the efficiency of work and learning. This article will introduce how to use Vue and Excel to automatically modify and export data.

1. How to use Vue to obtain and modify Excel data
In Vue, you can read and modify Excel files through the vue-xlsx plug-in. First, we need to install the vue-xlsx plug-in through npm:

npm install vue-xlsx --save

Copy after login

Then introduce and register vue-xlsx in main.js:

import VueXlsx from 'vue-xlsx' Vue.use(VueXlsx)

Copy after login

Next, we can use # in the Vue component ## Component to read Excel files and bind the data to Vue's data. For example, we have an Excel file named "excelData.xlsx", which contains a worksheet named "Sheet1". We can read the data like this:

Copy after login

At this time,

excelDatawill be bound to a two-dimensional array, where each row represents a row of data in the Excel table. You can display the data or perform other operations by traversingexcelData.

If we want to modify the data in the Excel file and update it to the page in real time, we can use the

component. For example, we have a button that, when clicked, will write "Hello World" to the first row and column of the Excel file:

Copy after login

In the above code, clicking the button triggers

updateDatamethod, you can modify the data to "Hello World" and automatically update it to the Excel file.

2. How to use Vue to export Excel files

In addition to reading and modifying Excel data, we can also use Vue to export Excel files. In Vue, we can use the xlsx-style plug-in to implement the export function. First, you need to install the xlsx-style plug-in through npm:

npm install xlsx-style --save

Copy after login

Then introduce the following code in main.js:

import 'xlsx-style' import FileSaver from 'file-saver' Object.defineProperty(Vue.prototype, '$fileSaver', { value: FileSaver })

Copy after login

In the Vue component, we can use the following code to export the Excel file:

Copy after login

In the above code, by clicking the button to trigger the

exportDatamethod,excelDatacan be exported to an Excel file named "Export Data.xlsx". In addition, by setting thecellStylesobject, we can also customize the exported table style.

Conclusion:

Through the intelligent splicing of Vue and Excel, we can realize automatic modification and export of data, which greatly improves the efficiency of work and study. I hope this article can help you make better use of front-end technology to process data.
