Golang导入导出Excel表格

最近项目开发中有涉及到Excel的导入与导出功能，特别是导出表格时需要特定的格式（单元格合并等），废话不多说，直接上代码了。

首先用到一个第三方库，实测还是很强大很好用的，就是这个https://github.com/qax-os/excelize

引用库

go get github.com/xuri/excelize/v2

导入表格

package mainimport ("encoding/json""github.com/xuri/excelize/v2""net/http""strings"
)func fileImport(w http.ResponseWriter, r *http.Request) {// 获取请求中的文件名formFile, _, err := r.FormFile("filename")if err != nil {w.Write([]byte("获取文件失败, " + err.Error()))return}// 关闭defer formFile.Close()//reader, err := excelize.OpenReader(formFile)if err != nil {w.Write([]byte("读取文件失败, " + err.Error()))return}// 关闭defer reader.Close()rows, err := reader.GetRows("Sheet1")if err != nil {w.Write([]byte("获取工作表失败, " + err.Error()))return}ret := make([]string, 0, 8)for i, row := range rows {// 每一行数据的列, 都是从0开始的, 一般0行都是表头if i == 0 {continue}value1 := row[0] // 第一列value2 := row[1] // 第二列// 去除空格value1 = strings.Trim(strings.TrimSpace(value1), "\n")value2 = strings.Trim(strings.TrimSpace(value2), "\n")//ret = append(ret, value1+","+value2)}bytes, _ := json.Marshal(ret)w.Write(bytes)return
}func main() {// HTTP服务http.HandleFunc("/fileImport", fileImport)err := http.ListenAndServe(":8192", nil)if err != nil {panic(err)}
}

表格格式

执行后效果

导出表格

package mainimport ("encoding/json""fmt""github.com/xuri/excelize/v2""net/http""strings"
)func fileExport(w http.ResponseWriter, r *http.Request) {file := excelize.NewFile()defer file.Close()// 设置页sheetName := "Sheet1"// 创建sheet, err := file.NewSheet(sheetName)if err != nil {w.Write([]byte("创建失败, " + err.Error()))return}// 设置单元格格式style := &excelize.Style{Border: nil,Fill:   excelize.Fill{},Font:   nil,Alignment: &excelize.Alignment{Horizontal:      "center",Indent:          0,JustifyLastLine: false,ReadingOrder:    0,RelativeIndent:  0,ShrinkToFit:     false,TextRotation:    0,Vertical:        "center",WrapText:        false,},Protection:    nil,NumFmt:        0,DecimalPlaces: nil,CustomNumFmt:  nil,NegRed:        false,}styleID, _ := file.NewStyle(style)// 设置表头_ = file.SetCellValue(sheetName, "A1", "款")_ = file.SetCellStyle(sheetName, "A1", "A1", styleID)_ = file.SetCellValue(sheetName, "B1", "尺码")_ = file.SetCellStyle(sheetName, "B1", "B1", styleID)// 设置值for i := 0; i < 5; i++ {lineStr := fmt.Sprintf("%d", i+2)//_ = file.SetCellValue(sheetName, "A"+lineStr, "基础款")_ = file.SetCellStyle(sheetName, "A"+lineStr, "A"+lineStr, styleID)//_ = file.SetCellValue(sheetName, "B"+lineStr, "1:2:3:4:5:6")_ = file.SetCellStyle(sheetName, "B"+lineStr, "B"+lineStr, styleID)}//file.SetActiveSheet(sheet)//buffer, err := file.WriteToBuffer()if err != nil {w.Write([]byte("导出失败, " + err.Error()))return}w.Header().Set("Content-Disposition", fmt.Sprintf("attachment; filename=%s", "导出文件.xlsx"))w.Header().Set("Content-Type", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")w.Write(buffer.Bytes())
}func main() {// HTTP服务http.HandleFunc("/fileImport", fileImport)http.HandleFunc("/fileExport", fileExport)err := http.ListenAndServe(":8192", nil)if err != nil {panic(err)}
}
