针对最近的项目中的Excel数据处理需求，整理如下脚本可供参考：

模块1：数据拆分工具

功能：将大规模数据按机器编号和时间拆分成多个工作表，便于后续分析。

使用代码：

Sub Macro2()    Dim counter As Integer    Dim day As Integer    Dim counter2 As Integer    Dim filename As String    Dim daystr As String        For counter = 1 To 10        counter2 = 0 + counter        filename = "G:\电工杯\2\一号机\01"        Application.Goto Reference:="R1C" + LTrim(Str(counter2)) + ":R51844C" + LTrim(Str(counter2))        Selection.Copy        Workbooks.Add        Range("A4").Select        ActiveSheet.Paste        Application.CutCopyMode = False        day = counter        daystr = LTrim(day)        If day < 10 Then            daystr = "0" + daystr        End If        ActiveWorkbook.SaveAs filename:=filename + daystr + ".xls", _                              FileFormat:=xlExcel8, Password:="", WriteResPassword:="", _                              ReadOnlyRecommended:=False, CreateBackup:=False        ActiveWindow.Close    Next counterEnd Sub

说明：

逐个机器编号（循环1-10）和时间天数（1-10天）拆分数据。

数据从原始表格的指定范围复制到新工作簿中。

文件命名结合机器编号和日期，便于管理和查找。

模块2：方差和平均功率计算

功能：从处理过的数据中计算均值、方差和平均功率，输出结果为新的文件。

使用代码：

Sub Macro1()    Dim counter As Integer    Dim i As Long    Dim columnnum As Integer    Dim datanum As String    Dim filenamepro As String        For counter = 1 To 10        filenamepro = "G:\电工杯\2\一号机\01"        datanum = LTrim(Str(counter))        If counter < 10 Then            datanum = "0" + datanum        End If        Workbooks.Open filename:=filenamepro + datanum + ".xls"        Cells.Select        Selection.Copy        Workbooks.Add        Cells.Select        ActiveSheet.Paste        Application.CutCopyMode = False                Dim startnum As Long        For i = 1 To 4320            Range("B" + LTrim(Str(4 + i))).Select            startnum = 5 + (i - 1) * 12            ActiveCell.FormulaR1C1 = "=AVERAGE(R" + LTrim(Str(startnum)) + "C1:R" + LTrim(Str(startnum + 11)) + "C1)"            Next i        ActiveWorkbook.SaveAs filename:=filenamepro + datanum + "DATA" + ".xls", _                              FileFormat:=xlExcel8, Password:="", WriteResPassword:="", _                              ReadOnlyRecommended:=False, CreateBackup:=False        ActiveWindow.Close        If (i Mod 100) = 0 Then            ActiveWorkbook.Save        End If        Next counter    Range("C5").Select    ActiveCell.FormulaR1C1 = "=VAR(R5C2:R4324C2)"    ActiveWorkbook.Save    ActiveWindow.Close    ActiveWindow.Close    Next counterEnd Sub

说明：

对于每个处理后的数据文件，计算特定范围内的平均值和方差。

结果保存为新的工作表，便于后续分析。

处理完所有文件后，收藏并关闭工作簿。

模块3：均值和方差后的数据输出

功能：将平均功率和方差结果分别输出为新的工作表，便于数据汇总。

使用代码：

Sub Macro2()    ChDir "G:\电工杯\2\一号机"        For counter = 1 To 10        filenamepro = "G:\电工杯\2\一号机\01"        datanum = LTrim(Str(counter))        If counter < 10 Then            datanum = "0" + datanum        End If                Workbooks.Open filename:=filenamepro + datanum + "DATA" + ".xls"        Columns("B:B").Select        Selection.Copy        Workbooks.Add        Columns("A:A").Select        Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=False                Range("A4").Select        ActiveCell.FormulaR1C1 = "平均功率"        Range("C4").Select        ActiveCell.FormulaR1C1 = "方差"        ActiveWorkbook.SaveAs filename:=filenamepro + datanum + "DATA平均功率" + ".xls", _                              FileFormat:=xlExcel8, Password:="", WriteResPassword:="", ReadOnlyRecommended:=False, CreateBackup:=False        ActiveWindow.Close        Columns("C:C").Select        Selection.Copy        Workbooks.Add        Columns("A:A").Select        Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=False                Range("A4").Select        ActiveCell.FormulaR1C1 = "方差"        ActiveWorkbook.SaveAs filename:=filenamepro + datanum + "DATA方差" + ".xls", _                              FileFormat:=xlExcel8, Password:="", WriteResPassword:="", ReadOnlyRecommended:=False, CreateBackup:=False        ActiveWindow.Close    Next counterEnd Sub
