Excel·VBA单元格区域数据对比差异标记颜色-Toy模板网

这篇具有很好参考价值的文章主要介绍了Excel·VBA单元格区域数据对比差异标记颜色。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

之前的一篇博客《Excel·VBA单元格重复值标记颜色》，是对重复的整行标记颜色
而本文是按行对比2个单元格区域的数据，并对有差异的区域（一个单元格区域有的，而另一个单元格区域没有的）标记颜色，且只要存在任意1个字符不同的，则标记颜色

差异标色

代码写为自定义函数使用更为方便，并使用 Union 方法在每个单元格区域判断结束后统一标色

Function 单元格区域数据对比标色_不同(ByVal rng1 As Range, ByVal rng2 As Range)
    '2个单元格区域数据按行对比，1个区域中有另1个区域中无则标色，每行中任意1个字符不同则标色
    Dim dict1 As Object, dict2 As Object, delimiter$, color_index&, i&, j&, temp$, k, color_rng As Range
    Set dict1 = CreateObject("scripting.dictionary"): delimiter = Chr(28)  '分隔符
    Set dict2 = CreateObject("scripting.dictionary"): color_index = 6  '标记黄色
    For i = 1 To rng1.Rows.Count  'rng1写入字典
        temp = ""
        For j = 1 To rng1.Columns.Count
            temp = temp & delimiter & rng1.Cells(i, j).Value
        Next
        If Not dict1.Exists(temp) Then
            Set dict1(temp) = rng1.Rows(i)
        Else
            Set dict1(temp) = Union(dict1(temp), rng1.Rows(i))
        End If
    Next
    For i = 1 To rng2.Rows.Count  'rng2写入字典
        temp = ""
        For j = 1 To rng2.Columns.Count
            temp = temp & delimiter & rng2.Cells(i, j).Value
        Next
        If Not dict2.Exists(temp) Then
            Set dict2(temp) = rng2.Rows(i)
        Else
            Set dict2(temp) = Union(dict2(temp), rng2.Rows(i))
        End If
    Next
    For Each k In dict1.keys  '遍历dict1，判断所有键在dict2中是否存在，不存在则写入标色区域color_rng
        If Not dict2.Exists(k) Then
            If color_rng Is Nothing Then
                Set color_rng = dict1(k)
            Else
                Set color_rng = Union(color_rng, dict1(k))
            End If
        End If
    Next
    'Union无法跨工作表使用，故先对color_rng标色1次
    If Not color_rng Is Nothing Then color_rng.Interior.ColorIndex = color_index: Set color_rng = Nothing
    For Each k In dict2.keys  '遍历dict2，判断所有键在dict1中是否存在
        If Not dict1.Exists(k) Then
            If color_rng Is Nothing Then
                Set color_rng = dict2(k)
            Else
                Set color_rng = Union(color_rng, dict2(k))
            End If
        End If
    Next
    If Not color_rng Is Nothing Then color_rng.Interior.ColorIndex = color_index: Set color_rng = Nothing
    Debug.Print "单元格区域数据对比标色_不同，完成"
End Function

举例

Sub 测试()
    Dim rng1 As Range, rng2 As Range
    Set rng1 = Worksheets("表1").[a1].CurrentRegion
    Set rng2 = Worksheets("表2").[a1].CurrentRegion
    a = 单元格区域数据对比标色_不同(rng1, rng2)
End Sub

对比差异并标记黄色

相同标色

与上面的 差异标色 不同，对一行单元格所有数据相同的标记颜色，代码差异很小

Function 单元格区域数据对比标色_相同(ByVal rng1 As Range, ByVal rng2 As Range)

    Set dict2 = CreateObject("scripting.dictionary"): color_index = 6  '标记黄色

        temp = ""
        For j = 1 To rng1.Columns.Count
            temp = temp & delimiter & rng1.Cells(i, j).Value
        Next
