使用VBA将固定文本文件导入excel

Question

我正在使用VBA将固定文本文件导入excel文件。 我在用数字十进制固定列的拟合（自动拟合）时遇到问题。

我有一个最多为5027.1202024.0000.0000.000.0000.0000.0000的小数，并且想简化为5027.12，因为我的列不合适并且只是分开。 除了声明几个数组并固定宽度之外，还有别的方法吗？ 文本文件已经以某种方式固定。 我还是vba的新手，我会尽一切帮助。 谢谢

而不是使用TextToColumns或Workbooks.OpenText ; 只需读取文本文件并处理数据即可。

Sub ImportPrepayment2()
    Dim fpath As Variant
    Dim wb As Excel.Workbook
    Dim ws As Excel.Worksheet
    Dim Text As String
    On Error GoTo terminatemsg

    Set wb = Excel.ActiveWorkbook
    Set ws = Excel.ActiveSheet

    fpath = Application.GetOpenFilename(Filefilter:="text Files(*.txt; *.txt), *.txt; *.txt", Title:="open")

    If fpath = False Then Exit Sub

    Application.ScreenUpdating = False
    Application.DisplayAlerts = False

    Text = getTextfileData(fpath)
    If Len(Text) Then
        ProcessData Text
        AdjustDates
    Else
        MsgBox fpath & " is empty", vbInformation, "Import Cancelled"
        Exit Sub
    End If

    Columns.EntireColumn.AutoFit
    Sheets(1).Move Before:=wb.Sheets(1)

terminatemsg:
    Application.ScreenUpdating = True
    Application.DisplayAlerts = True
    If Err.Number <> 0 Then MsgBox Err.Number & " " & Err.Description

End Sub

Sub ProcessData(Text As String)
    Dim x As Long, y As Long, z As Long
    Dim data, vLine

    data = Split(Text, vbCrLf)
    x = 2
    Range("A1:R1").Value = Array("Supplier Name", "Supplier Number", "Inv Curr Code CurCode", "Payment CurCode", "Invoice Type", "Invoice Number", "Voucher Number", "Invoice Date", "GL Date", "Invoice Amount", "Withheld Amount", "Amount Remaining", "Description", "Account Number", "Invoice", "Withheld", "Amt", "User")

    For y = 0 To UBound(data)
        If InStr(data(y), "|") Then
            vLine = Split(data(y), "|")
            If Not Trim(vLine(0)) = "Supplier" Then

                For z = 0 To UBound(vLine)
                    vLine(z) = Trim(vLine(z))

                    If vLine(z) Like "*.*.*.*.*.*.*.*" Then vLine(z) = Left(vLine(z), InStr(vLine(z), ".") + 2)

                Next
                Cells(x, 1).Resize(1, UBound(vLine) + 1).Value = vLine
                x = x + 1
            End If
        End If
    Next

End Sub

Sub AdjustDates()
    Dim x As Long

    For x = 2 To Range("B" & Rows.Count).End(xlUp).row
        If Cells(x, "R") = vbNullString Then Cells(x, "M").Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
    Next

End Sub

Function getTextfileData(FILENAME As Variant) As String
    Const ForReading = 1
    Dim fso, MyFile
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set MyFile = fso.OpenTextFile(FILENAME, ForReading)
    getTextfileData = MyFile.ReadAll
    MyFile.Close
End Function

Answer 2

将此代码添加到Columns.EntireColumn.AutoFit之前。

Sub ProcessUsedRange()
    Dim r As Range
    Dim regex As Object, Match As Object
    Set regex = CreateObject("VBScript.RegExp")
    With regex
        .Pattern = "\d{4}.\d{4}.\d{4}.\d{3}.\d{4}.\d{4}.\d{4}"
        .Global = True
    End With

    For Each r In ActiveSheet.UsedRange
        If regex.Test(r.Text) Then
            For Each Match In regex.Execute(r.Value)
                'The apostrophe is to keep the data formatted as text
                r.Value = "'" & Replace(r.Value, Match.Value, "")
            Next
        End If
    Next
End Sub

你也应该改变

MsgBox Err.Number & " " & Err.Description

至

If Err.Number <> 0 then MsgBox Err.Number & " " & Err.Description
