1.打开Excel，按“Alt”+“F11”，弹出如下窗口

2.双击选中要拆分的sheet，输入如下代码，如下图所示

Sub cfb()

Dim r, c, i, WJhangshu, WJshu, bt As Long

r = Range("A" & Rows.Count).End(xlUp).Row

c = Cells(1, Columns.Count).End(xlToLeft).Column

bt = 1 'title

WJhangshu = 200 'num

WJshu = IIf(r - bt Mod 20000, Int((r - bt) / WJhangshu), Int((r - bt) / WJhangshu) + 1)

For i = 0 To WJshu

    Workbooks.Add

    Application.DisplayAlerts = False

    ActiveWorkbook.SaveAs Filename:=ThisWorkbook.Path & "\" & Format(i, String(Len(WJshu), 0)) & ".xlsx"

    Application.DisplayAlerts = True

    ThisWorkbook.ActiveSheet.Range("A1").Resize(bt, c).Copy ActiveSheet.Range("A1")

    ThisWorkbook.ActiveSheet.Range("A" & bt + i * WJhangshu + 1).Resize(WJhangshu, c).Copy _

    ActiveSheet.Range("A" & bt + 1)

    ActiveWorkbook.Close True

Next

End Sub

3.回到Excel文件，按“Alt”+“F8”，弹出窗口，选择刚才的宏，点击“执行”或“单步执行”

注：如果数据量很大，又拆分的很小，最好选择“单步执行”，否则会很卡....（电脑性能好当我没说）

4.等待执行结束，检查文件，搞定！
