一、excel文件批量转换格式为csv文件

1. 打开一个Excel工具，查看菜单中是否有【开发工具】，如果没有，需要手动添加该工具。具体步骤如下，通过【文件】->【选项】，弹出Excel选项对话框，

2. 菜单中出现了【开发工具】，

3. 通过点击菜单【VB】，弹出代码编辑框，输入如下代码，

Sub SaveToCSVs()Dim fDir As StringDim wB As WorkbookDim wS As WorksheetDim fPath As StringDim sPath As StringfPath = "X:\excel文件目录\"sPath = "X:\CSV文件保存目录\"fDir = Dir(fPath)Do While (fDir <> "")If Right(fDir, 4) = ".xls" Or Right(fDir, 5) = ".xlsx" ThenOn Error Resume NextSet wB = Workbooks.Open(fPath & fDir)'MsgBox (wB.Name)For Each wS In wB.SheetswS.SaveAs sPath & wB.Name & ".csv", xlCSVNext wSwB.Close FalseSet wB = NothingEnd IffDir = DirOn Error GoTo 0LoopEnd Sub

4. 点击【运行】，

5. 等待若干时间，在目标文件夹下，生成所要的csv文件。

二、将多个csv合并到一个csv中

将全部的csv文件放到一个文件夹中cmd打开cmd，切换到存放csv的文件夹数据分析输入命令

copy *.csv 你本身起的文件名.csv

以后按回车等待完成，打开文件夹就能够看到合成的csv。
