The champion combination of Vue and Excel: How to realize dynamic summation and export of data

Introduction:
In the era of modern data management and analysis, Excel, as a classic and commonly used office tool, is Widely used in all walks of life. As a popular front-end framework, Vue provides developers with many convenient methods to process and display data. This article will introduce how to combine Vue and Excel to realize the dynamic summing and exporting of data.

1. Dynamic summation of data
In actual work, we often encounter the need to sum up the data in the table. In Vue, you can use computed properties to dynamically add data. The following is a simple sample code:

In the above code, Vue's computed attribute (computed) function is used to traverse the people array, and the age of each person is accumulated, and finally the total age is obtained. In the template, we can directly reference this calculated property to display the total age.

2. Export data to Excel
In addition to summing data, we usually also need to export data to Excel files for better data analysis or sharing. Vue provides many libraries and plug-ins to help achieve this function, the most commonly used of which are the "xlsx" and "file-saver" libraries.

First, we need to install these two libraries:

npm install xlsx file-saver --save

Then, let’s look at a sample code to export data to an Excel file:

In the above code , we first introduced the XLSX and file-saver libraries. Then, in the exportData method, use the API of the XLSX library to convert the data into Excel format, and finally save the generated Excel file locally through the file-saver library.

Conclusion:
Through the combination of Vue and Excel, we can realize the dynamic summation and export functions of data, and facilitate data analysis and sharing. This article uses Vue's computed properties and the XLSX library to achieve this purpose. I hope this tutorial will be helpful to you and allow you to better utilize the powerful functions of Vue and Excel in actual projects.
