Go 语言读写 Excel

Excelize 是 Go 语言编写的一个用来操作 Office Excel 文档类库，基于 ECMA-376 Office OpenXML 标准。可以使用它来读取、写入 XLSX 文件。相比较其他的开源类库，Excelize 支持写入原本带有图片(表)的文档，还支持向 Excel 中插入图片，并且在保存后不会丢失图表样式。

安装

go get github.com/xuri/excelize/v2

创建 XLSX

package main

import (
	"fmt"

	"github.com/xuri/excelize/v2"
)

func main() {
	f := excelize.NewFile()
	// Create a new sheet.
	index := f.NewSheet("Sheet2")
	// Set value of a cell.
	f.SetCellValue("Sheet2", "A2", "Hello world.")
	f.SetCellValue("Sheet1", "B2", 100)
	// Set active sheet of the workbook.
	f.SetActiveSheet(index)
	// Save xlsx file by the given path.
	err := f.SaveAs("./Book1.xlsx")
	if err != nil {
		fmt.Println(err)
	}
}

读取已有文档

package main

import (
	"fmt"

	"github.com/xuri/excelize/v2"
)

func main() {
	f, err := excelize.OpenFile("./Book1.xlsx")
	if err != nil {
		fmt.Println(err)
		return
	}
	// Get value from cell by given worksheet name and axis.
	cell, err := f.GetCellValue("Sheet1", "B2")
	if err != nil {
		fmt.Println(err)
		return
	}
	fmt.Println(cell)
	// Get all the rows in the Sheet1.
	rows, err := f.GetRows("Sheet1")
	for _, row := range rows {
		for _, colCell := range row {
			fmt.Print(colCell, "\t")
		}
		fmt.Println()
	}
}

向 Excel 中插入图表

package main

import (
	"fmt"

	"github.com/xuri/excelize/v2"
)

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}
	f := excelize.NewFile()
	for k, v := range categories {
		f.SetCellValue("Sheet1", k, v)
	}
	for k, v := range values {
		f.SetCellValue("Sheet1", k, v)
	}
	err := f.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"}}`)
	if err != nil {
		fmt.Println(err)
		return
	}
	// Save xlsx file by the given path.
	err = f.SaveAs("./Book1.xlsx")
	if err != nil {
		fmt.Println(err)
	}
}

向 Excel 中插入图片

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
	}
	// Insert a picture.
	err = f.AddPicture("Sheet1", "A2", "./image1.png", "")
	if err != nil {
		fmt.Println(err)
	}
	// Insert a picture to worksheet with scaling.
	err = f.AddPicture("Sheet1", "D2", "./image2.jpg", `{"x_scale": 0.5, "y_scale": 0.5}`)
	if err != nil {
		fmt.Println(err)
	}
	// Insert a picture offset in the cell with printing support.
	err = f.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)
	}
	// Save the xlsx file with the origin path.
	err = f.Save()
	if err != nil {
		fmt.Println(err)
	}
}
