将多个CSV导入到单个工作簿中的多个工作表

Question

我该怎么做？基本上我希望将多个CSV文件导入到多个工作表，但仅限于一个工作簿。这是我要循环的VBA代码。我需要循环来查询C:\test\

中的所有CSV

Sub Macro()
With ActiveSheet.QueryTables.Add(Connection:= _
    "TEXT;C:\test\test1.csv", Destination:=Range("$A$1"))
    .Name = "test1"
    .FieldNames = True
    .RowNumbers = False
    .FillAdjacentFormulas = False
    .PreserveFormatting = True
    .RefreshOnFileOpen = False
    .RefreshStyle = xlInsertDeleteCells
    .SavePassword = False
    .SaveData = True
    .AdjustColumnWidth = True
    .RefreshPeriod = 0
    .TextFilePromptOnRefresh = False
    .TextFilePlatform = 437
    .TextFileStartRow = 1
    .TextFileParseType = xlDelimited
    .TextFileTextQualifier = xlTextQualifierDoubleQuote
    .TextFileConsecutiveDelimiter = False
    .TextFileTabDelimiter = False
    .TextFileSemicolonDelimiter = False
    .TextFileCommaDelimiter = True
    .TextFileSpaceDelimiter = False
    .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1)
    .TextFileTrailingMinusNumbers = True
    .Refresh BackgroundQuery:=False
End With
Sheets.Add After:=Sheets(Sheets.Count)
End Sub

This guy绝对钉了它。非常简洁的代码，并在2010年完美适合我。所有功劳归于他（Jerry Beaucaire）。我是从论坛here找到的。

    Loop

Application.ScreenUpdating = True
Set wbCSV = Nothing
End Sub

请注意，如果导入csv，则不会像处理重复的工作表名称那样处理错误。

这使用早期绑定，因此您需要在Microsoft.Scripting.Runtime

中的 Tools..References 下引用VBE

Dim fs  As New FileSystemObject
Dim fo As Folder
Dim fi As File
Dim wb As Workbook
Dim ws As Worksheet
Dim sname As String

Sub loadall()
    Set wb = ThisWorkbook

    Set fo = fs.GetFolder("C:\TEMP\")

    For Each fi In fo.Files
        If UCase(Right(fi.name, 4)) = ".CSV" Then
            sname = Replace(Replace(fi.name, ":", "_"), "\", "-")

            Set ws = wb.Sheets.Add
            ws.name = sname
            Call yourRecordedLoaderModified(fi.Path, ws)
        End If
    Next
End Sub

Sub yourRecordedLoaderModified(what As String, where As Worksheet)
With ws.QueryTables.Add(Connection:= _
    "TEXT;" & what, Destination:=Range("$A$1"))
    .name = "test1"
    .FieldNames = True
    .RowNumbers = False
    .FillAdjacentFormulas = False
    .PreserveFormatting = True
    .RefreshOnFileOpen = False
    .RefreshStyle = xlInsertDeleteCells
    .SavePassword = False
    .SaveData = True
    .AdjustColumnWidth = True
    .RefreshPeriod = 0
    .TextFilePromptOnRefresh = False
    .TextFilePlatform = 437
    .TextFileStartRow = 1
    .TextFileParseType = xlDelimited
    .TextFileTextQualifier = xlTextQualifierDoubleQuote
    .TextFileConsecutiveDelimiter = False
    .TextFileTabDelimiter = False
    .TextFileSemicolonDelimiter = False
    .TextFileCommaDelimiter = True
    .TextFileSpaceDelimiter = False
    .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1)
    .TextFileTrailingMinusNumbers = True
    .Refresh BackgroundQuery:=False
End With
Sheets.Add After:=Sheets(Sheets.Count)
End Sub

您可以使用Dir过滤掉并运行csv个文件

Sub MacroLoop()
Dim strFile As String
Dim ws As Worksheet
strFile = Dir("c:\test\*.csv")
Do While strFile <> vbNullString
Set ws = Sheets.Add
With ws.QueryTables.Add(Connection:= _
    "TEXT;" & "C:\test\" & strFile, Destination:=Range("$A$1"))
    .Name = strFile
    .FieldNames = True
    .RowNumbers = False
    .FillAdjacentFormulas = False
    .PreserveFormatting = True
    .RefreshOnFileOpen = False
    .RefreshStyle = xlInsertDeleteCells
    .SavePassword = False
    .SaveData = True
    .AdjustColumnWidth = True
    .RefreshPeriod = 0
    .TextFilePromptOnRefresh = False
    .TextFilePlatform = 437
    .TextFileStartRow = 1
    .TextFileParseType = xlDelimited
    .TextFileTextQualifier = xlTextQualifierDoubleQuote
    .TextFileConsecutiveDelimiter = False
    .TextFileTabDelimiter = False
    .TextFileSemicolonDelimiter = False
    .TextFileCommaDelimiter = True
    .TextFileSpaceDelimiter = False
    .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1)
    .TextFileTrailingMinusNumbers = True
    .Refresh BackgroundQuery:=False
End With
strFile = Dir
Loop
End Sub

我没试过，但我会选择this：

Dim NumFound As Long 
With Application.FileSearch 
    .NewSearch
    .LookIn = "C:\test\"
    .FileName = "*.csv"
    If .Execute() > 0 Then 
        For i = 1 To .FoundFiles.Count
            With ActiveSheet.QueryTables.Add(Connection:= _
                "TEXT;" & "C:\test\" & (Application.FileSearch.FoundFiles(i)), Destination:=Range("$A$1"))
                ...
            End With
            Sheets.Add After:=Sheets(Sheets.Count)
        Next i
    End If
End With

我有183个csv文件要压缩为一个工作簿，每个csv文件一个工作表是为了方便数据分析，并且不想一次手动进行。我在这个问题上尝试了评分最高的解决方案，但与另一个用户遇到了同样的问题； csv文件将打开，但不会将任何内容插入目标工作簿。我花了一些时间并调整了代码，以使其能够像在Excel 2016中那样工作。我已经很久没有使用Visual Basic进行编码了，所以我的代码可能还有很多改进的地方，但是它对我来说却是紧迫的。如果有人碰巧像我一样偶然发现了这个问题，我将粘贴下面使用的代码。
