# Excelize
|
||
|
||
## 简介
|
||
|
||
Excelize 是 Go 语言编写的用于操作 Office Excel 文档基础库，基于 ECMA-376，ISO/IEC 29500 国际标准。可以使用它来读取、写入由 Microsoft Excel™ 2007 及以上版本创建的电子表格文档。支持 XLAM / XLSM / XLSX / XLTM / XLTX 等多种文档格式，高度兼容带有样式、图片(表)、透视表、切片器等复杂组件的文档，并提供流式读写 API，用于处理包含大规模数据的工作簿。可应用于各类报表平台、云计算、边缘计算等系统。使用本类库要求使用的 Go 语言为 1.15 或更高版本，完整的 API 使用文档请访问 [go.dev](https://pkg.go.dev/github.com/xuri/excelize/v2) 或查看 [参考文档](https://xuri.me/excelize/)。

## 快速上手
|
||
|
||
### 安装
|
||
|
||
```bash
|
||
go get github.com/xuri/excelize
|
||
```
|
||
|
||
- 如果您使用 [Go Modules](https://go.dev/blog/using-go-modules) 管理软件包，请使用下面的命令来安装最新版本。
|
||
|
||
```bash
|
||
go get github.com/xuri/excelize/v2
|
||
```
|
||
|
||
### 创建 Excel 文档
|
||
|
||
下面是一个创建 Excel 文档的简单例子：
|
||
|
||
```go
|
||
package main
|
||
|
||
import (
|
||
"fmt"
|
||
|
||
"github.com/xuri/excelize/v2"
|
||
)
|
||
|
||
func main() {
|
||
f := excelize.NewFile()
|
||
// 创建一个工作表
|
||
index := f.NewSheet("Sheet2")
|
||
// 设置单元格的值
|
||
f.SetCellValue("Sheet2", "A2", "Hello world.")
|
||
f.SetCellValue("Sheet1", "B2", 100)
|
||
// 设置工作簿的默认工作表
|
||
f.SetActiveSheet(index)
|
||
// 根据指定路径保存文件
|
||
if err := f.SaveAs("Book1.xlsx"); err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
}
|
||
```
|
||
|
||
### 读取 Excel 文档
|
||
|
||
下面是读取 Excel 文档的例子：
|
||
|
||
```go
|
||
package main
|
||
|
||
import (
|
||
"fmt"
|
||
|
||
"github.com/xuri/excelize/v2"
|
||
)
|
||
|
||
func main() {
|
||
f, err := excelize.OpenFile("Book1.xlsx")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
return
|
||
}
|
||
defer func() {
|
||
// 关闭工作簿
|
||
if err := f.Close(); err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
}()
|
||
// 获取工作表中指定单元格的值
|
||
cell, err := f.GetCellValue("Sheet1", "B2")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
return
|
||
}
|
||
fmt.Println(cell)
|
||
// 获取 Sheet1 上所有单元格
|
||
rows, err := f.GetRows("Sheet1")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
return
|
||
}
|
||
for _, row := range rows {
|
||
for _, colCell := range row {
|
||
fmt.Print(colCell, "\t")
|
||
}
|
||
fmt.Println()
|
||
}
|
||
}
|
||
```
|
||
|
||
### 在 Excel 文档中创建图表
|
||
|
||
使用 Excelize 生成图表十分简单，仅需几行代码。您可以根据工作表中的已有数据构建图表，或向工作表中添加数据并创建图表。

|
||
"A2": "Small", "A3": "Normal", "A4": "Large",
|
||
"B1": "Apple", "C1": "Orange", "D1": "Pear"}
|
||
values := map[string]int{
|
||
"B2": 2, "C2": 3, "D2": 3, "B3": 5, "C3": 2, "D3": 4, "B4": 6, "C4": 7, "D4": 8}
|
||
f := excelize.NewFile()
|
||
for k, v := range categories {
|
||
f.SetCellValue("Sheet1", k, v)
|
||
}
|
||
for k, v := range values {
|
||
f.SetCellValue("Sheet1", k, v)
|
||
}
|
||
if err := f.AddChart("Sheet1", "E1", `{

### 向 Excel 文档中插入图片
|
||
|
||
```go
|
||
package main
|
||
|
||
import (
|
||
"fmt"
|
||
_ "image/gif"
|
||
_ "image/jpeg"
|
||
_ "image/png"
|
||
|
||
"github.com/xuri/excelize/v2"
|
||
)
|
||
|
||
func main() {
|
||
f, err := excelize.OpenFile("Book1.xlsx")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
return
|
||
}
|
||
defer func() {
|
||
// 关闭工作簿
|
||
if err := f.Close(); err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
}()
|
||
// 插入图片
|
||
if err := f.AddPicture("Sheet1", "A2", "image.png", ""); err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
// 在工作表中插入图片，并设置图片的缩放比例
|
||
if err := f.AddPicture("Sheet1", "D2", "image.jpg",
|
||
`{"x_scale": 0.5, "y_scale": 0.5}`); err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
// 在工作表中插入图片，并设置图片的打印属性
|
||
if err := f.AddPicture("Sheet1", "H2", "image.gif", `{
|
||
"x_offset": 15,
|
||
"y_offset": 10,
|
||
"print_obj": true,
|
||
"lock_aspect_ratio": false,
|
||
"locked": false
|
||
}`); err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
// 保存工作簿
