# Excelize
|
||
|
||
## 简介
|
||
|
||
Excelize 是 Go 语言编写的用于操作 Office Excel 文档类库，基于 ECMA-376 Office OpenXML 标准。可以使用它来读取、写入由 Microsoft Excel™ 2007 及以上版本创建的 XLSX 文档。相比较其他的开源类库，Excelize 支持写入原本带有图片(表)、透视表和切片器等复杂样式的文档，还支持向 Excel 文档中插入图片与图表，并且在保存后不会丢失文档原有样式，可以应用于各类报表系统中。使用本类库要求使用的 Go 语言为 1.8 或更高版本，完整的 API 使用文档请访问 [godoc.org](https://godoc.org/github.com/360EntSecGroup-Skylar/excelize) 或查看 [参考文档](https://xuri.me/excelize/)。

|
||
## 快速上手
|
||
|
||
### 安装
|
||
|
||
```go
|
||
go get github.com/360EntSecGroup-Skylar/excelize
|
||
```
|
||
|
||
### 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/360EntSecGroup-Skylar/excelize"
|
||
)
|
||
|
||
func main() {
|
||
xlsx := excelize.NewFile()
|
||
// 创建一个工作表
|
||
index := xlsx.NewSheet("Sheet2")
|
||
// 设置单元格的值
|
||
xlsx.SetCellValue("Sheet2", "A2", "Hello world.")
|
||
xlsx.SetCellValue("Sheet1", "B2", 100)
|
||
// 设置工作簿的默认工作表
|
||
xlsx.SetActiveSheet(index)
|
||
// 根据指定路径保存文件
|
||
err := xlsx.SaveAs("./Book1.xlsx")
|
||
if 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/360EntSecGroup-Skylar/excelize"
|
||
)
|
||
|
||
func main() {
|
||
xlsx, err := excelize.OpenFile("./Book1.xlsx")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
return
|
||
}
|
||
// 获取工作表中指定单元格的值
|
||
cell := xlsx.GetCellValue("Sheet1", "B2")
|
||
fmt.Println(cell)
|
||
// 获取 Sheet1 上所有单元格
|
||
rows := xlsx.GetRows("Sheet1")
|
||
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。

|
||
|
||
```go
|
||
package main
|
||
|
||
import (
|
||
"fmt"
|
||
|
||
"github.com/360EntSecGroup-Skylar/excelize"
|
||
)
|
||
|
||
func main() {
|
||
categories := map[string]string{"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}
|
||
xlsx := excelize.NewFile()
|
||
for k, v := range categories {
|
||
xlsx.SetCellValue("Sheet1", k, v)
|
||
}
|
||
for k, v := range values {
|
||
xlsx.SetCellValue("Sheet1", k, v)
|
||
}
|
||
xlsx.AddChart("Sheet1", "E1", `{"type":"col3DClustered","series":[{"name":"Sheet1!$A$2","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$2:$D$2"},{"name":"Sheet1!$A$3","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$3:$D$3"},{"name":"Sheet1!$A$4","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$4:$D$4"}],"title":{"name":"Fruit 3D Clustered Column Chart"}}`)
|
||
// 根据指定路径保存文件
|
||
err := xlsx.SaveAs("./Book1.xlsx")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
}
|
||
|
||
```
|
||
|
||
### 向 Excel 文档中插入图片
|
||
|
||
```go
|
||
package main
|
||
|
||
import (
|
||
"fmt"
|
||
_ "image/gif"
|
||
_ "image/jpeg"
|
||
_ "image/png"
|
||
|
||
"github.com/360EntSecGroup-Skylar/excelize"
|
||
)
|
||
|
||
func main() {
|
||
xlsx, err := excelize.OpenFile("./Book1.xlsx")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
return
|
||
}
|
||
// 插入图片
|
||
err = xlsx.AddPicture("Sheet1", "A2", "./image1.png", "")
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
// 在工作表中插入图片，并设置图片的缩放比例
|
||
err = xlsx.AddPicture("Sheet1", "D2", "./image2.jpg", `{"x_scale": 0.5, "y_scale": 0.5}`)
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
// 在工作表中插入图片，并设置图片的打印属性
|
||
err = xlsx.AddPicture("Sheet1", "H2", "./image3.gif", `{"x_offset": 15, "y_offset": 10, "print_obj": true, "lock_aspect_ratio": false, "locked": false}`)
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
// 保存文件
|
||
err = xlsx.Save()
|
||
if err != nil {
|
||
fmt.Println(err)
|
||
}
|
||
}
|
||
```
