Excel 如何在一行中查找重复的单元格或值？

Question

我有一个数据集，其中每一行都属于一个独特的人，所以我想做的是在每一行中找到重复值。

我尝试使用条件格式，但它非常耗时，因为我必须将其应用于每一行，否则它会在所有行中找到重复项，而不仅仅是一行。

您能否建议一些可以帮助我的东西，它可以是公式或 vba 或条件格式的公式。

我使用宏记录器创建了一个宏，结果如下。如果我可以让它遍历一系列行并应用可能有帮助的格式

Sub DuplicatesRow1() ' ' DuplicatesRow Macro '

'
    Rows("251:251").Select
    Selection.FormatConditions.AddUniqueValues
    Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
    Selection.FormatConditions(1).DupeUnique = xlDuplicate
    With Selection.FormatConditions(1).Font
        .Color = -16383844
        .TintAndShade = 0
    End With
    With Selection.FormatConditions(1).Interior
        .PatternColorIndex = xlAutomatic
        .Color = 13551615
        .TintAndShade = 0
    End With
    Selection.FormatConditions(1).StopIfTrue = False
    Rows("252:252").Select
    Selection.FormatConditions.AddUniqueValues
    Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
    Selection.FormatConditions(1).DupeUnique = xlDuplicate
    With Selection.FormatConditions(1).Font
        .Color = -16383844
        .TintAndShade = 0
    End With
    With Selection.FormatConditions(1).Interior
        .PatternColorIndex = xlAutomatic
        .Color = 13551615
        .TintAndShade = 0
    End With
    Selection.FormatConditions(1).StopIfTrue = False
    Rows("253:253").Select
    Selection.FormatConditions.AddUniqueValues
    Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
    Selection.FormatConditions(1).DupeUnique = xlDuplicate
    With Selection.FormatConditions(1).Font
        .Color = -16383844
        .TintAndShade = 0
    End With
    With Selection.FormatConditions(1).Interior
        .PatternColorIndex = xlAutomatic
        .Color = 13551615
        .TintAndShade = 0
    End With
    Selection.FormatConditions(1).StopIfTrue = False
    Range("E259").Select End Sub

我对此进行了进一步的研究，并设法提出了以下似乎对我有用的代码。我是 VBA 新手，没有足够的经验，所以如果我的代码可以进一步改进，请告诉我

Private Sub HighlightDuplicateRow(row As Integer)

Dim report As Worksheet
Set report = Excel.ActiveSheet
report.Cells(row, row).EntireRow.Select
    Selection.FormatConditions.AddUniqueValues
    Selection.FormatConditions(Selection.FormatConditions.Count).SetFirstPriority
    Selection.FormatConditions(1).DupeUnique = xlDuplicate
    With Selection.FormatConditions(1).Font
        .Color = -16383844
        .TintAndShade = 0
    End With
    With Selection.FormatConditions(1).Interior
        .PatternColorIndex = xlAutomatic
        .Color = 13551615
        .TintAndShade = 0
    End With
    Selection.FormatConditions(1).StopIfTrue = False
End Sub


Sub DuplicatesInEachRow()
Dim counter As Integer, limit As Variant
counter = 2
limit = InputBox("Give me last row number", "Highlight Duplicates in a Row")
If limit = "" Then Exit Sub
Do Until counter > limit
Call HighlightDuplicateRow(counter)
counter = counter + 1
Loop
End Sub

Answer 2

这是一个循环，它将在每一行上设置一个条件格式。我根据您的示例数据和代码使用了工作表和范围引用。您可以修改这些以适合您的确切数据集。

我还要注意，如果有很多行，我担心这会导致 Excel 中的性能问题，因为格式的数量可能会严重增加您的文件大小并影响性能。

Sub LoopCF()

Dim ws As Worksheet
Set ws = Sheets("Sheet1")

'Dim lRow As Long
'lRow = ws.Range("A2").End(xlDown).Row 'will give row 200 as long as contiguous rows

Dim rng As Range, cel As Range
Set rng = ws.Range("B2:B200") 'ws.Range("B2:B" & lRow)

For Each cel In rng

    With cel.Resize(1, 4)

        .FormatConditions.AddUniqueValues
        .FormatConditions(.FormatConditions.Count).SetFirstPriority

        With .FormatConditions(1)

            .DupeUnique = xlDuplicate

            With .Font
                .Color = -16383844
                .TintAndShade = 0
            End With

            With .Interior
                .PatternColorIndex = xlAutomatic
                .Color = 13551615
                .TintAndShade = 0
            End With

            .StopIfTrue = False

        End With

    End With

Next

End Sub
