Question

我有一个将特定范围的行转换为csv文件的vbscript。
我的问题是它还复制空行而不需要蓝行。如何在复制之前删除这些完整的空行或将其从复制中排除？我的代码：

Public Sub xlsToCsv()    
    Const WorkingDir = "C:\Test\"
    Const xlCSV = 24
    Const xlUp = -4162

    Dim fso, SaveName, myFile
    Dim objExcel, objWorkbook, wsSource, wsTarget

    myFile = "source_file.xlsx"
    SaveName = "test.csv"

    With CreateObject("Scripting.FilesystemObject")
        If Not .FileExists(WorkingDir & myFile) Then
            MsgBox "File not found:" & vbCrLf & WorkingDir & myFile, vbInformation, "Script Cancelled"
            WScript.Quit
        End If
    End With

    Set objExcel = CreateObject("Excel.Application")

    objExcel.Visible = False
    objExcel.DisplayAlerts = False

    Set objWorkbook = objExcel.Workbooks.Open(WorkingDir & myFile)
    Set wsSource = objWorkbook.Sheets(1)
    Set wsTarget = objWorkbook.Sheets.Add()

    With wsTarget
    .Cells(1,1).Value = "ID"
    .Cells(1,2).Value = "NAME"
    .Cells(1,3).Value = "DESC"
    End With

    With wsSource
    .Range("F7", .Range("F" & .Rows.Count).End(xlUp)).Copy wsTarget.Range("A2")
    .Range("A7", .Range("A" & .Rows.Count).End(xlUp)).Copy wsTarget.Range("B2")
    .Range("E7", .Range("E" & .Rows.Count).End(xlUp)).Copy wsTarget.Range("C2")
    End With

    objWorkbook.SaveAs WorkingDir & SaveName, xlCSV
    objWorkbook.Close True

    Set objWorkbook = Nothing
    Set objExcel = Nothing
    Set fso = Nothing
    Set myFolder = Nothing
End Sub

call xlsToCsv()

这是我原创的一种替代方法，旨在提高性能。在这种情况下，VBScript代码不是使用Excel来创建csv文件，而是使用FileSystemObject创建的文本文件直接写入csv文件。我用更大的源数据测试了这一点，它似乎比原来快一点 - 1500行约40秒。打开Excel应用程序仍然存在开销（大约5-10秒）但是你可以做的不多。如果性能对您很重要，那么您可以进行其他改进。

如果电子表格中有数值，则可能需要进行一些格式转换为适合csv输出的字符串值，因为Excel倾向于对转换为文本的数字使用指数表示法，这并不总是您想要的。我还使用了引号和逗号分隔符，但您可以为CSV输出使用不同的格式约定。您可能希望更改WriteLine的使用，因为这会在最后一行之后追加一个CrLf，这可能会在下游被解释为空行。
