Question

如何通过Excel VBA在一组，一组或多个单独的文件中导入CSV文件，而不是一次一个？

Answer 1

我有点困惑的是，大多数版本的Excel都会打开.csv文件，没有任何问题。

strPath = "C:\Docs\"
strFile = Dir(strPath & "*.csv")

Do While strFile <> ""
    Workbooks.Open Filename:=strPath & strFile
    ActiveWorkbook.SaveAs Filename:=strPath & Mid(strFile, 1, InStr(strFile, ".") - 1) _
        & "Conv.xls", FileFormat:=xlNormal

    strFile = Dir
Loop

Answer 2

这将快速将文件转换为一维数组

Open "myfile.csv" For Input As 1
Dim Txt As String
Txt = Input(LOF(1), 1)
Close #1
Dim V As Variant
V = Split(Txt, ",")

然后V包含单个列中的所有项目，NB第一项是V（0）

Answer 3

这是避免在Excel中打开csv文件时获得的重新计算的另一种方法。

将空白工作表添加到工作簿中，并将以下代码添加到工作表的对象

Function getCsv(fn)
    Dim d, scrup As Boolean
    scrup = Application.ScreenUpdating
    Application.ScreenUpdating = False
    With Me.QueryTables.Add( _
            Connection:="TEXT;" & fn, _
            Destination:=Me.Range("A1") _
        )
        .Name = "data"
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshStyle = xlOverwriteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = False
        .TextFilePromptOnRefresh = False
        .TextFilePlatform = 850
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileCommaDelimiter = True
        .Refresh BackgroundQuery:=False
    End With

    d = Me.Names(1).RefersToRange.Value

    Me.Names(1).Delete
    Me.UsedRange.Rows.Delete

    Application.ScreenUpdating = scrup
    getCsv = d
End Function

您可能还想隐藏工作表，以免任何人意外使用它。然后就可以像这样使用

dim d
d = getCsv("C:\temp\some.csv")

有一点让我感到担忧的是，每次使用该函数时，Name都会增加（例如data_1，data_2，...），因此如果这些名称在某处保存，可能会出现稳定性问题。

Answer 4

您可以编写一个简单的控制台应用程序来解析一批csv文件并将它们保存到excel文件中不是最简单的解决方案，但它可能是一种选择。

Answer 5

您也可以使用workbooks.opentext

Answer 6

我原来的想法如下。鉴于此数据

Dog Names,Dog Ages,Collar Size
Woof,3,4
Bowser,2,5
Ruffy,4.5,6
Angel,1,7
Demon,7,8
Dog,9,2

创建三个全局数组，称为Dog_Names，Dog_Ages和Collar_Size，并使用CSV文件中的数据填充它们。

这一点VBScript完成了这项工作并显示了结果。从wscript.echo子例程中的x中删除注释标记，看看它是否全部发生。

Option Explicit

Dim FSO
Set FSO = CreateObject( "Scripting.FileSystemObject" )

Dim oStream
Dim sData
Dim aData

Set oStream = fso.OpenTextFile("data.csv")
sData       = oStream.ReadAll
aData       = Split( sData, vbNewLine )

Dim sLine
sLine = aData(0)

Dim aContent
aContent = Split( sLine, "," )

Dim aNames()
Dim nArrayCount
nArrayCount = UBound( aContent )
ReDim aNames( nArrayCount )

Dim i

For i = 0 To nArrayCount
  aNames(i) = Replace( aContent( i ), " ", "_" )
  x "dim " & aNames(i) & "()"
Next

For j = 0 To nArrayCount
  x "redim " & aNames(j) & "( " & UBound( aData ) - 1 & " )"
Next

Dim j
Dim actual
actual = 0

For i = 1 To UBound( aData )
  sLine = aData( i )
  If sLine <> vbnullstring Then
    actual = actual + 1
    aContent = Split( sLine, "," )
    For j = 0 To nArrayCount
      x aNames(j) & "(" & i - 1 & ")=" & Chr(34) & aContent(j) & Chr(34)
    Next
  End If
Next

For j = 0 To nArrayCount
  x "redim preserve " & aNames(j) & "(" & actual - 1 & ")"
Next

For i = 0 To actual - 1
  For j = 0 To nArrayCount
    x "wscript.echo aNames(" & j & ")," & aNames(j) & "(" & i & ")"
  Next
Next

Sub x( s )
  'wscript.echo s
  executeglobal s
End Sub

结果如下所示

>cscript "C:\Documents and Settings\Bruce\Desktop\datathing.vbs"
Dog_Names Woof
Dog_Ages 3
Collar_Size 4
Dog_Names Bowser
Dog_Ages 2
Collar_Size 5
Dog_Names Ruffy
Dog_Ages 4.5
Collar_Size 6
Dog_Names Angel
Dog_Ages 1
Collar_Size 7
Dog_Names Demon
Dog_Ages 7
Collar_Size 8
Dog_Names Dog
Dog_Ages 9
Collar_Size 2
