忽略空白单元格CSV导出Excel工作表数据

Question

我想确定一种方法，用于'忽略'由Excel工作表数据导致的CSV文件上的空白单元格。

空白单元格将是用户在一行或下一行中输入的结果（但是两行将永远不会被填充，但脚本中引用的标头需要保持不变）。一行涉及到一个操作系统的磁盘需求，而下面的一行涉及另一个操作系统的磁盘需求（如果适用）;磁盘要求的格式仍然适用于当前格式的标题。

当前VBA代码应用于Excel工作表时，空白行中与第一个OS磁盘需求相关的缺失数据通过输入空白单元“推送”下一行的信息。我想找到一种方法让VBA代码“忽略”空白行，并将前进行的数据输入到该单元格中。我使用的VBA代码：

Sub WriteCSVFile() 

Dim My_filenumber As Integer 
Dim logSTR As String 

My_filenumber = FreeFile 

logSTR = logSTR & "Header1" & " , " 
logSTR = logSTR & "Header2" & " , " 
logSTR = logSTR & "Header3" & " , " 
logSTR = logSTR & "Header4" & " , " 
logSTR = logSTR & "Header5" & " , " 
logSTR = logSTR & "Header6" & " , " 
logSTR = logSTR & "Header7" & " , " 
logSTR = logSTR & "Header8" & " , " 
logSTR = logSTR & "Header9" & " , " 
logSTR = logSTR & "Header10" & " , " 
logSTR = logSTR & "Header11" & " , " 
logSTR = logSTR & "Header12" & " , " 
logSTR = logSTR & "Header13" & " , " 
logSTR = logSTR & Chr(13) 
logSTR = logSTR & Cells(18, "C").Value & " , " 
logSTR = logSTR & Cells(19, "C").Value & " , " 
logSTR = logSTR & Cells(20, "C").Value & " , " 
logSTR = logSTR & Cells(21, "C").Value & " , " 
logSTR = logSTR & Cells(22, "C").Value & " , " 
logSTR = logSTR & Cells(26, "C").Value & " , " 
logSTR = logSTR & Cells(27, "C").Value & " , " 
logSTR = logSTR & Cells(28, "C").Value & " , " 
logSTR = logSTR & Cells(29, "C").Value & " , " 
logSTR = logSTR & Cells(30, "C").Value & " , " 
logSTR = logSTR & Cells(31, "C").Value & " , " 
logSTR = logSTR & Cells(32, "C").Value & " , " 

如果没有数据从logSTR = logSTR &将细胞（31， “C”）值& “” 我想有数据从logSTR = logSTR所得。 &单元格（32，“C”）。值&“，”放置在该单元格中，而不是留下空白。这将允许数据的格式（用逗号分隔的3个值）与Header11，Header12和Header13（而不是Header12，Header13和No Header）对齐。

logSTR = logSTR & Chr(13) 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & Cells(36, "C").Value & " , " 
logSTR = logSTR & Cells(37, "C").Value & " , " 
logSTR = logSTR & Cells(38, "C").Value & " , " 
logSTR = logSTR & Cells(39, "C").Value & " , " 
logSTR = logSTR & Cells(40, "C").Value & " , " 
logSTR = logSTR & Cells(41, "C").Value & " , " 
logSTR = logSTR & Cells(42, "C").Value & " , " 
logSTR = logSTR & Chr(13) 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & "" & " , " 
logSTR = logSTR & Cells(46, "C").Value & " , " 
logSTR = logSTR & Cells(47, "C").Value & " , " 
logSTR = logSTR & Cells(48, "C").Value & " , " 
logSTR = logSTR & Cells(49, "C").Value & " , " 
logSTR = logSTR & Cells(50, "C").Value & " , " 
logSTR = logSTR & Cells(51, "C").Value & " , " 
logSTR = logSTR & Cells(52, "C").Value & " , " 

Open "Z:\SHARED DRIVE\RequestDirectory\" & ThisWorkbook.Name & ".csv" For Append As #My_filenumber 
    Print #My_filenumber, logSTR 
Close #My_filenumber

Answer 1

像下面，你可以使用一个辅助功能：

Function BuildValuesString(colIndex As String, rows As String) As String 
    Dim val As Variant 

    For Each val In Split(rows, ",") 
     If Cells(val, colIndex) <> "" Then BuildValuesString = BuildValuesString & Cells(val, colIndex).Value & " , " 
    Next val 
End Function 

，并利用它在你的主代码中，例如：

logSTR = logSTR & Cells(18, "C").Value & " , " 
logSTR = logSTR & Cells(19, "C").Value & " , " 
logSTR = logSTR & Cells(20, "C").Value & " , " 
logSTR = logSTR & Cells(21, "C").Value & " , " 
logSTR = logSTR & Cells(22, "C").Value & " , " 
logSTR = logSTR & Cells(26, "C").Value & " , " 
logSTR = logSTR & Cells(27, "C").Value & " , " 
logSTR = logSTR & Cells(28, "C").Value & " , " 
logSTR = logSTR & Cells(29, "C").Value & " , " 
logSTR = logSTR & Cells(30, "C").Value & " , " 
logSTR = logSTR & Cells(31, "C").Value & " , " 
logSTR = logSTR & Cells(32, "C").Value & " , " 

将成为：

logSTR = logSTR & BuildValuesString("C", "18,19,20,21,22,26,27,28,29,30,31,32") 

，并以同样的方式，你可以使用其他两个帮手：

Function BuildNullStrings(numNullStrings As Long) As String 
    Dim iNullStrings As Long 

    For iNullStrings = 1 To numNullStrings 
     BuildNullStrings = BuildNullStrings & "" & " , " 
    Next iNullStrings 
End Function 

Function BuildHeadersString(maxHeader As Long) As String 
    Dim iHeader As Long 

    For iHeader = 1 To maxHeader 
     BuildHeadersString = BuildHeadersString & "Header" & iHeader & " , " 
    Next iHeader 
End Function 

让你的整个代码将向下缩短：

Sub WriteCSVFile2() 

    Dim My_filenumber As Integer 
    Dim logSTR As String 

    My_filenumber = FreeFile 

    logSTR = logSTR & BuildHeadersString(13) 
    logSTR = logSTR & Chr(13) 

    logSTR = logSTR & BuildValuesString("C", "18,19,20,21,22,26,27,28,29,30,31,32") 

    logSTR = logSTR & Chr(13) 
    logSTR = logSTR & BuildNullStrings(5) 

    logSTR = logSTR & BuildValuesString("C", "36,37,38,39,40,41,42") 

    logSTR = logSTR & Chr(13) 
    logSTR = logSTR & BuildNullStrings(5) 

    logSTR = logSTR & BuildValuesString("C", "46,47,48,49,50,51,52") 


    Open "Z:\SHARED DRIVE\RequestDirectory\" & ThisWorkbook.Name & ".csv" For Append As #My_filenumber 
     Print #My_filenumber, logSTR 
    Close #My_filenumber 


End Sub
