今天一个朋友由于要将本地excel数据导入到saas平台,但是saas平台规定了excel大小条数,并且要求按规定格式命名excel文件。刚好闲来无事,便花了点时间用golang写了个excel文件分割处理程序。
操作步骤
下载excel分割器.zip,解压,将需要分割的文件重命名为input.xlsx后台,放在根目录下,双击运行exe文件,即可在output目录生成分割好的excel文件列表了。

处理逻辑
核心处理逻辑代码如下:
package main
import (
"fmt"
"github.com/360EntSecGroup-Skylar/excelize"
"os"
"path"
)
var CellCols = []string{"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"}
func ChunkExcel() {
f, err := excelize.OpenFile(fmt.Sprintf("%s%s", ExecPath, ConfigData.InputFile))
if err != nil {
fmt.Println(err)
return
}
fmt.Println("---------- 开始生成 ----------")
var titles []string
excelFiles := map[string]*excelize.File{}
fileName := fmt.Sprintf("output%s%d-%d.xlsx", string(os.PathSeparator), 1, ConfigData.ChunkSize)
excelFiles[fileName] = excelize.NewFile()
firstSheet := excelFiles[fileName].NewSheet("Sheet1")
excelFiles[fileName].SetActiveSheet(firstSheet)
sheets := f.GetSheetMap()
for _, sheetName := range sheets {
rows := f.GetRows(sheetName)
rowIndex := 2
numIndex := 0
for i, row := range rows {
if i == 0 {
//标题行
for j, colCell := range row {
titles = append(titles, colCell)
//写入表头
excelFiles[fileName].SetCellValue("Sheet1", fmt.Sprintf("%s1", CellCols[j]), colCell)
}
} else {
//开始写入文件
for j, colCell := range row {
excelFiles[fileName].SetCellValue("Sheet1", fmt.Sprintf("%s%d", CellCols[j], rowIndex), colCell)
}
numIndex++
if numIndex % ConfigData.ChunkSize == 0 {
//保存
fmt.Println(fmt.Sprintf("开始生成文件%s", path.Base(fileName)))
if err := excelFiles[fileName].SaveAs(fileName); err != nil {
fmt.Println(err)
return
}
//生成新文件
fileName = fmt.Sprintf("output%s%d-%d.xlsx", string(os.PathSeparator), numIndex+1, numIndex+ConfigData.ChunkSize)
excelFiles[fileName] = excelize.NewFile()
firstSheet = excelFiles[fileName].NewSheet("Sheet1")
excelFiles[fileName].SetActiveSheet(firstSheet)
rowIndex = 1
for j, colCell := range titles {
//写入表头
excelFiles[fileName].SetCellValue("Sheet1", fmt.Sprintf("%s1", CellCols[j]), colCell)
}
}
rowIndex++
}
}
//最后的保存
fmt.Println(fmt.Sprintf("开始生成文件%s", path.Base(fileName)))
if err := excelFiles[fileName].SaveAs(fileName); err != nil {
fmt.Println(err)
return
}
break
}
fmt.Println("---------- 生成结束 ----------")
}
