这是我的问题的详细信息。

  • 我有数千个 csv 文件需要合并到一个 excel 文件中。
  • 只需要提取每个csv文件的某些数据，A2，G2和H单元格的最高值。
  • 提取的每个 csv 文件都将按提取顺序排列在新的工作簿中。（csv A2->A 细胞，csv G2->B 细胞，csv H->细胞）

因为我有数千个 csv 文件，是否可以通过选择不同文件夹中的所有 csv 文件来组合所有数据？

非常感谢您的关注。

Dim rngSourceRange1  As Range
Dim rngSourceRange2 As Range
Dim rngSourceRange3 As Range

Set wkbCrntWorkBook = ActiveWorkbook

Dim SelectedItemNumber As Integer

Dim HighestValueRng As Range
Dim Highest As Double

Do

SelectedItemNumber = SelectedItemNumber + 1

With Application.FileDialog(msoFileDialogOpen)
    .Filters.Clear
    .Filters.Add "Excel 2007", "*.xlsx; *.xlsm; *.xlsa", 1

For SelectedItemNumber = 1 To .SelectedItems.Count

    If .SelectedItems.Count > 0 Then
        Workbooks.Open .SelectedItems(SelectedItemNumber)
        Set wkbSourceBook = ActiveWorkbook
        Set rngSourceRange1 = ActiveCell.Offset(1, 0)
        Set rngSourceRange2 = ActiveCell.Offset(1, 6)


        wkbCrntWorkBook.Activate

        Set rngDestination1 = ActiveCell.Offset(1, 0)
        Set rngDestination2 = ActiveCell.Offset(1, 1)

        ActiveCell.Offset(1, 2).Value = Application.WorksheetFunction.Max(Columns("H"))

        For intColumnCount = 1 To rngSourceRange1.Columns.Count

            If intColumnCount = 1 Then
                rngSourceRange1.Columns(intColumnCount).Copy rngDestination1
            Else
                rngSourceRange1.Columns(intColumnCount).Copy rngDestination1.End(xlDown).End(xlDown).End(xlUp).Offset(1)
            End If
        Next

        For intColumnCount = 1 To rngSourceRange2.Columns.Count

            If intColumnCount = 1 Then
                rngSourceRange2.Columns(intColumnCount).Copy rngDestination2
            Else
                rngSourceRange2.Columns(intColumnCount).Copy rngDestination2.End(xlDown).End(xlDown).End(xlUp).Offset(1)
            End If
        Next

        ActiveCell.Offset(1, 0).Select

        wkbSourceBook.Close False
    End If

Next SelectedItemNumber

End With

YesOrNoAnswerToMessageBox = MsgBox("Continue?", vbYesNo)

Loop While YesOrNoAnswerToMessageBox = vbYes


Set wkbCrntWorkBook = Nothing
Set wkbSourceBook = Nothing
Set rngSourceRange1 = Nothing
Set rngSourceRange2 = Nothing
Set rngDestination1 = Nothing
Set rngDestination2 = Nothing
intColumnCount = Empty

End Function

最大值的结果总是返回零。为什么？任何人都可以纠正我吗？

如果我完全理解您的要求，则不是肯定的，但请看看这是否对您有帮助。

将此代码粘贴到新工作簿中的模块中，并将 CSV 文件放入名为“CSV”的子文件夹中。结果应出现在新工作簿的 Sheet1 中。请注意，它只会检查具有 CSV 文件扩展名的文件。如果您需要更改它，请查看该行If Right(file.Name, 3) = "csv"

Sub ParseCSVs()
    Dim CSVPath
    Dim FS
    Dim file
    Dim wkb As Excel.Workbook
    Dim ResultsSheet As Worksheet
    Dim RowPtr As Range
    Dim CSVUsed As Range

    Set ResultsSheet = Sheet1

    'Clear the results sheet
    ResultsSheet.Cells.Delete

    Set FS = CreateObject("Scripting.FileSystemObject")

    'The CSV files are stored in a "CSV" subfolder of the folder where
    'this workbook is stored.
    CSVPath = ThisWorkbook.Path & "\CSV"

    If Not FS.FolderExists(CSVPath) Then
        MsgBox "CSV folder does not exist."
        Exit Sub
    End If

    ResultsSheet.Range("A1:D1").Value = Array("CSV A2", "CSV G2", "CSV Max of H", "File")
    ResultsSheet.Range("A1").EntireRow.Font.Bold = True
    Set RowPtr = ResultsSheet.Range("A2")
    For Each file In FS.GetFolder(CSVPath).Files
        If Right(file.Name, 3) = "csv" Then 'Only look at files with .csv extension
            Set wkb = Application.Workbooks.Open(file.Path)
            Set CSVUsed = wkb.Sheets(1).UsedRange

            RowPtr.Range("A1") = CSVUsed.Range("A2")
            RowPtr.Range("B1") = CSVUsed.Range("G2")
            RowPtr.Range("C1") = Application.WorksheetFunction.Max(CSVUsed.Range("H:H"))
            RowPtr.Range("D1") = file.Name

            wkb.Close False

            Set RowPtr = RowPtr.Offset(1)
        End If
    Next

    ResultsSheet.Range("A:D").EntireColumn.AutoFit
End Sub
