无法在第三张工作表中填充唯一值，将第二张工作表的值与第一个工作表的值进行比较

Question

我在 Excel 工作簿中有三张工作表 - main、specimen 和 output。工作表main 和speciment 包含一些信息。两张纸中的一些信息是相同的，但很少有不同的。我的意图是将这些信息粘贴到output 中，这些信息在speciment 中可用，但在main 中不可用。

我尝试过 [目前它填充了许多产生重复的单元格]：

Sub getData()
    Dim cel As Range, celOne As Range, celTwo As Range
    Dim ws As Worksheet: Set ws = ThisWorkbook.Worksheets("main")
    Dim ws1 As Worksheet: Set ws1 = ThisWorkbook.Worksheets("specimen")
    Dim ws2 As Worksheet: Set ws2 = ThisWorkbook.Worksheets("output")


    For Each cel In ws.Range("A2:A" & ws.Cells(Rows.Count, 1).End(xlUp).row)
        For Each celOne In ws1.Range("A2:A" & ws1.Cells(Rows.Count, 1).End(xlUp).row)
            If cel(1, 1) <> celOne(1, 1) Then ws2.Range("A" & Rows.Count).End(xlUp).Offset(1, 0).value = celOne(1, 1)
        Next celOne
    Next cel
End Sub

main 包含：

UNIQUE ID   FIRST NAME          LAST NAME
A0000477    RICHARD NOEL        AARONS 
A0001032    DON WILLIAM         ABBOTT 
A0290191    REINHARDT WESTER    CARLSON 
A0290284    RICHARD WARREN      CARLSON 
A0002029    RAYMOND MAX         ABEL 
A0002864    DARRYL SCOTT        ABLING 
A0003916    GEORGES YOUSSEF     ACCAOUI 

specimen 包含：

UNIQUE ID   FIRST NAME       LAST NAME
A0288761    ROBERT HOWARD    CARLISLE 
A0290284    RICHARD WARREN   CARLSON 
A0290688    THOMAS A         CARLSTROM 
A0002029    RAYMOND MAX      ABEL 
A0002864    DARRYL SCOTT     ABLING 

output 应包含 [预期]：

UNIQUE ID   FIRST NAME      LAST NAME
A0288761    ROBERT HOWARD   CARLISLE 
A0290688    THOMAS A        CARLSTROM 

我怎样才能做到这一点？

Answer 1

如果您有最新版本的 Excel，带有 FILTER 函数和动态数组，您可以使用 Excel 公式来完成。

我将您的 Main 和 Specimen 数据更改为表格。

然后您可以在输出工作表上将此公式输入到单个单元格中：

=FILTER(specTbl,ISNA(MATCH(specTbl[UNIQUE ID],mnTbl[UNIQUE ID],0)))

其余字段将自动填充结果。

对于 VBA 解决方案，我喜欢使用字典和 VBA 数组来提高速度。

'set reference to microsoft scripting runtime
'  or use late-binding
Option Explicit
Sub findMissing()
    Dim wsMain As Worksheet, wsSpec As Worksheet, wsOut As Worksheet
    Dim dN As Dictionary, dM As Dictionary
    Dim vMain As Variant, vSpec As Variant, vOut As Variant
    Dim I As Long, v As Variant

With ThisWorkbook
    Set wsMain = .Worksheets("Main")
    Set wsSpec = .Worksheets("Specimen")
    Set wsOut = .Worksheets("Output")
End With

'Read data into vba arrays for processing speed
With wsMain
    vMain = .Range(.Cells(1, 1), .Cells(.Rows.Count, 1).End(xlUp)).Resize(columnsize:=3)
End With

With wsSpec
    vSpec = .Range(.Cells(1, 1), .Cells(.Rows.Count, 1).End(xlUp)).Resize(columnsize:=3)
End With

'add ID to names dictionary
Set dN = New Dictionary
For I = 2 To UBound(vMain, 1)
    dN.Add Key:=vMain(I, 1), Item:=I
Next I

'add missing ID's to missing dictionary
Set dM = New Dictionary
For I = 2 To UBound(vSpec, 1)
    If Not dN.Exists(vSpec(I, 1)) Then
        dM.Add Key:=vSpec(I, 1), Item:=WorksheetFunction.Index(vSpec, I, 0)
    End If
Next I

'write results to output array
ReDim vOut(0 To dM.Count, 1 To 3)
    vOut(0, 1) = "UNIQUE ID"
    vOut(0, 2) = "FIRST NAME"
    vOut(0, 3) = "LAST NAME"
I = 0
For Each v In dM.Keys
    I = I + 1
    vOut(I, 1) = dM(v)(1)
    vOut(I, 2) = dM(v)(2)
    vOut(I, 3) = dM(v)(3)
Next v

Dim R As Range
With wsOut
    Set R = .Cells(1, 1)
    Set R = R.Resize(UBound(vOut, 1) + 1, UBound(vOut, 2))

    With R
        .EntireColumn.Clear
        .Value = vOut
        .Style = "Output"
        .EntireColumn.AutoFit
    End With
End With

End Sub

两者都显示相同的结果（除了公式解决方案不会带来列标题；但您可以在上述原始公式上方的单元格中使用公式 =mnTbl[#Headers] 来做到这一点）。

另一种选择是将每个范围内的每一行的值连接起来并将它们存储在数组中。

然后比较数组并输出唯一值。

在这种情况下，您的唯一性来自评估整行，而不仅仅是唯一 ID。

请阅读代码的 cmets 并根据您的需要进行调整。

Public Sub OutputUniqueValues()

    Dim mainSheet As Worksheet
    Dim specimenSheet As Worksheet

    Dim specimenFirstRow As Long

    Dim outputCounter As Long

    Set mainSheet = ThisWorkbook.Worksheets("main")
    Set specimenSheet = ThisWorkbook.Worksheets("specimen")
    Set outputSheet = ThisWorkbook.Worksheets("output")

    ' Row at which the output range will be printed (not including headers)
    outputCounter = 2

    ' Process main data ------------------------------------

    ' Row at which the range to be evaluated begins
    mainFirstRow = 2

    ' Turn range rows into array items
    mainArray = ProcessRangeData(mainSheet, mainFirstRow)


    ' Process specimen data ------------------------------------

    ' Row at which the range to be evaluated begins
    specimenFirstRow = 2

    ' Turn range rows into array items
    specimenArray = ProcessRangeData(specimenSheet, specimenFirstRow)

    ' Look for unique values and output results in sheet

    ' Set the range of specimen sheet
    Set dataRange = dataSheet.Range("A" & firstRow & ":C" & lastRow)

    ' Redimension the array to the number of rows in range
    ReDim dataArray(dataRange.Rows.Count)

    counter = 0

    ' Join each row values so it's easier to compare them later and add them to an array
    For Each evalRowRange In dataRange.Rows

        ' Use Trim function if you want to omit the first and last characters if they are spaces
        dataArray(counter) = Trim(evalRowRange.Cells(1).Value) & "|" & Trim(evalRowRange.Cells(2).Value) & "|" & Trim(evalRowRange.Cells(3).Value)

        counter = counter + 1

    Next evalRowRange

    ProcessRangeData = dataArray

End Function

Private Sub OutputUniquesFromArrays(ByVal outputSheet As Worksheet, ByVal outputCounter As Long, ByVal mainArray As Variant, ByVal specimenArray As Variant)

    Dim specimenFound As Boolean
    Dim specimenCounter As Long
    Dim mainCounter As Long

    ' Look for unique values ------------------------------------

    For specimenCounter = 0 To UBound(specimenArray)

        specimenFound = False

        ' Check if value in specimen array exists in main array
        For mainCounter = 0 To UBound(mainArray)

            If specimenArray(specimenCounter) = mainArray(mainCounter) Then specimenFound = True

        Next mainCounter

        If specimenFound = False Then
            ' Write values to output sheet
            outputSheet.Range("A" & outputCounter).Value = Split(specimenArray(specimenCounter), "|")(0)
            outputSheet.Range("B" & outputCounter).Value = Split(specimenArray(specimenCounter), "|")(1)
            outputSheet.Range("C" & outputCounter).Value = Split(specimenArray(specimenCounter), "|")(2)
            outputCounter = outputCounter + 1
        End If

    Next specimenCounter
End Sub
