Example of implementation of Go language operation Excel

In modern software development, data processing is a common and critical task. Excel files, as a popular format for data exchange, often need to be read and modified by programs. Today, we will explore a powerful Go library, excelize, which provides a comprehensive API to manipulate Excel files (XLSX).

Introduction to excelize

excelize is a library written in Go language that supports reading and writing XLSX files, including but not limited to creating new workbooks, reading and modifying cell data, setting styles, adding charts, processing data verification, etc. It is compatible with Microsoft Excel™ 2007 and later, and is fully compatible with LibreOffice and Google Sheets.

Install excelize

Installing excelize is very simple, you only need to use Go's package management tools. Open your terminal or command prompt and execute the following command:

go get /xuri/excelize/v2

This will install the latest version of the excelize library and its dependencies.

Basic use cases

Create and save Excel files

First, let's look at a simple example, creating a new Excel file and saving it locally.

package main

import (
    "fmt"
    "/xuri/excelize/v2"
)

func main() {
    f := ()
    sheetName := "Sheet1"
    
    // Create worksheets    index,_ := (sheetName)
    // Set the value of the cell    (sheetName, "A1", "Hello")
    (sheetName, "B1", "World")
    
    // Set the worksheet to active state    (index)
    
    // Save the file    if err := (""); err != nil {
        (err)
    }
}

Read Excel files

Next, let's look at how to read an existing Excel file.

package main

import (
    "fmt"
    "/xuri/excelize/v2"
)

func main() {
    f, err := ("")
    if err != nil {
        (err)
        return
    }
    defer ()
    
    // Get the name of the worksheet    sheetName := (0)
    
    // Get all cells on the worksheet    rows, err := (sheetName)
    if err != nil {
        (err)
        return
    }
    
    for _, row := range rows {
        for _, cell := range row {
            (cell, "\t")
        }
        ()
    }
}

Summarize

excelize is a feature-rich and easy-to-use Go library that greatly simplifies the read and write operations of Excel files. Whether in the fields of data processing, automated report generation, or data analysis, excelize is a powerful tool. Through the above case, we can see the basic usage of excelize, including creating and saving Excel files and reading data. These are just part of the excelize feature, and more advanced features are waiting for you to explore and use.
