这里有几个关于VBA代码的对话，以在Excel中查找具有不同数据长度的多个列之间的所有可能组合。对话包括3列，4列和5列，但我需要使用14列进行此操作。这个对话中给出的5列代码是我使用的： VBA - Write all possible combinations of 4 columns of data 但是我收到以下错误：＆＃34;运行时错误＆＃39; 6＆＃39;：溢出＆＃34;当我去调试时它会突出显示这一行：
Set out1 = Range("G2", Range("K2").Offset(UBound(c1) * UBound(c2) * UBound(c3) * UBound(c4) * UBound(c5) * UBound(c6) * UBound(c7) * UBound(c8) * UBound(c9) * UBound(c10) * UBound(c11) * UBound(c12) * UBound(c13) * UBound(c14)))
以下是我从5个列中找到的示例中调整的完整代码：

另外，作为一个注释，我尝试调整代码，以便我的输入开始在电子表格的顶部（A1副A66我目前有），这没有帮助。另外，我知道在我用作参考的原始代码中它列出了＆＃34; Dim j As Long，k As Long，l As Long等）并且我缩短了它，但我最初使用了长形而且仍然得到了错误。任何帮助将不胜感激。我是VBA的全体业余爱好者，所以如果错误很明显，我很抱歉。我试图研究错误代码，但我无法找到为什么我的具体搞乱了。非常感谢您的时间。
非常尊重， 吨。

溢出意味着该数字太高而无法存储为您希望的数据类型。 Offset参数是Long，因此最大输入值为2147483648，因为它不会导致溢出。既然你说你的最大列大小是8而且只有8个非平凡的列，那么就必须有其他的东西。
具有讽刺意味的是，问题是由只有一个条目的列引起的：）
您正在设置如下列：
Set col1 = Range("A66", Range("A66").End(xlDown))
我不打算这样做但是如果＆＃34; A66＆＃34;是该列中具有条目的最后一个单元格，.End(xlDown)将一直向下到表格的底部。这就是你的高数字来自哪里。
使用Cells(rows.count,1).End(xlUp)查找A列中的最后一个非空单元格：
Set col1 = Range("A66", Cells(rows.count,1).End(xlUp))
当然这只解决了Overflow问题（希望如此），你可能最终会得到比你的行计数更长的东西，这需要花费很长时间。
编辑：顺便说一下，Dim i, j, k As Long只将最后一个变量设置为Long，其他变量设置为Variant。它与
Dim i
Dim j
Dim k as Long

你可以通过以下方式做到这一点：
Option Explicit
Sub test()
Dim inputRng As Range
Set inputRng = ThisWorkbook.Sheets("Sheet1").Range("A2:E5") 'change this to fit your needs
Dim inputVal() As Variant
ReDim inputVal(1 To inputRng.Columns.Count)
Dim holder() As Variant
Dim i, j, k, xCol, xRow
j = 1: k = 1
'load in values
For Each xCol In inputRng.Columns
If Len(xCol.Cells(2, 1)) Then
xRow = xCol.Cells(1, 1).End(xlDown).Row
Else
xRow = xCol.Cells(1, 1).Row
End If
If xRow > (xCol.Rows.Count + xCol.Row - 1) Then xRow = (xCol.Rows.Count + xCol.Row - 1)
ReDim holder(0 To xRow - xCol.Cells(1, 1).Row + 1)
holder(0) = UBound(holder)
j = j * holder(0)
For i = 1 To holder(0)
holder(i) = xCol.Cells(i).Value
Next
inputVal(k) = holder
k = k + 1
Next
Dim outputVal() As Variant
ReDim outputVal(1 To j, 1 To inputRng.Columns.Count)
k = 1
For i = UBound(outputVal, 2) To 1 Step -1
For j = 0 To UBound(outputVal) - 1
outputVal(j + 1, i) = inputVal(i)((Int(j / k) Mod inputVal(i)(0)) + 1)
Next
k = k * inputVal(i)(0)
Next
Dim outputRng As Range
Set outputRng = ThisWorkbook.Sheets("Sheet1").Range("G1") 'set here the first cell to start output
outputRng.Resize(UBound(outputVal), UBound(outputVal, 2)).Value = outputVal
End Sub
只需设置输入值的范围和输出的左上角单元格。
但请记住：如果j出现溢出：有很多组合，只需要处理很多。 （并且也永远不会适合1张）
在这种情况下，将整个过程分成2个部分，然后告诉大家将第二部分添加到第一部分中的每个项目......可能没有人会这样做：P
如果您有任何疑问，请询问：）
