VBA查找和替换不适用于所有列 [英] VBA find and replace not working for all columns

问题描述

我正在使用一段遍历Excel工作表的代码，使用其中的键将另一组数据复制到其中.两个数据集(数据集A到数据集B)如下所示:

I am using a piece of code that loops through a Excel worksheet, uses the keys from it to copy another set of data into it. The two datasets (Dataset A to Dataset B) looks like following:

数据集A:

Key  Val1  Val2  Val3
123  yes   up    right
324  no    down  right
314  no    up    left

数据集B:

Key  Val1  Val2  Val3
123
314
324

运行脚本后，它将根据密钥复制数据.我的代码适用于Val1和Val2，但仅导致Val3的空白条目，这是意外的和不需要的.我的代码如下:

When the script is ran, it copies the data based on the Key. My code works for Val1 and Val2, but results in only blank entries for Val3, which is unexpected and unwanted. My code is as follows:

    Sub copyData()
    Dim i As Long, arr As Variant, dict As Object

    Set dict = CreateObject("scripting.dictionary")
    dict.comparemode = vbTextCompare

    With Worksheets("COMBINED")
        'put combined!a:d into a variant array
        arr = .Range(.Cells(2, "A"), .Cells(.Rows.Count, "D").End(xlUp)).Value2
        'loop through array and build dictionary keys from combined!a:a, dictionary item from rows b:d
        For i = LBound(arr, 1) To UBound(arr, 1)
            dict.Item(arr(i, 1)) = arr(i, 2)
            dict.Item(arr(i, 2)) = arr(i, 3)
            dict.Item(arr(1, 3)) = arr(1, 4)
        Next i
    End With

    With Worksheets("All SAMs Backlog")
        arr = .Range(.Cells(3, "C"), .Cells(.Rows.Count, "C").End(xlUp).Offset(0, 3)).Value2
        'loop through array and if c:c matches combined!a:a then put combined!b:b into d:d
        For i = LBound(arr, 1) To UBound(arr, 1)
            If dict.exists(arr(i, 1)) Then
                arr(i, 2) = dict.Item(arr(i, 1))
                arr(i, 3) = dict.Item(arr(i, 2))
                arr(i, 4) = dict.Item(arr(i, 3))
            Else
                arr(i, 2) = vbNullString
                arr(i, 3) = vbNullString
                arr(i, 4) = vbNullString
            End If
        Next i
        'put populated array back into c3 (resized by rows and columns)
        .Cells(3, "C").Resize(UBound(arr, 1), UBound(arr, 2)) = arr
    End With

    MsgBox ("done")

End Sub

推荐答案

使用组合列A作为字典键，并将多列组合到一个数组中作为字典项存储

Use Combined column A as the dictionary key and combine the multiple columns into an array to be stored as the dictionary Item

Sub tranferData()
    Dim i As Long, arr As Variant, dict As Object

    Set dict = CreateObject("scripting.dictionary")
    dict.comparemode = vbTextCompare

    With Worksheets("COMBINED")
        'put combined!a:d into a variant array
        arr = .Range(.Cells(2, "A"), .Cells(.Rows.Count, "D").End(xlUp)).Value2
        'loop through array and build dictionary keys from combined!a:a, dictionary item from rows b:d
        For i = LBound(arr, 1) To UBound(arr, 1)
            'add key and multiple items as array
            If not dict.exists(arr(i, 1)) Then _
              dict.Add Key:=arr(i, 1), Item:=Array(arr(i, 2), arr(i, 3), arr(i, 4))
        Next i
    End With

    With Worksheets("All SAMs Backlog")
        arr = .Range(.Cells(3, "C"), .Cells(.Rows.Count, "C").End(xlUp).Offset(0, 3)).Value2
        'loop through array and if c:c matches combined!a:a then put combined!b:d into d:f
        For i = LBound(arr, 1) To UBound(arr, 1)
            If dict.exists(arr(i, 1)) Then
                arr(i, 2) = dict.Item(arr(i, 1))(0)
                arr(i, 3) = dict.Item(arr(i, 1))(1)
                arr(i, 4) = dict.Item(arr(i, 1))(2)
            Else
                arr(i, 2) = vbNullString
                arr(i, 3) = vbNullString
                arr(i, 4) = vbNullString
            End If
        Next i
        'put populated array back into c3 (resized by rows and columns)
        .Cells(3, "C").Resize(UBound(arr, 1), UBound(arr, 2)) = arr
    End With

    MsgBox ("done")

End Sub
