请使用下一种适应方式。它不选择，不使用剪贴板：

For x = 1 To LastRow
    If left(cells(x, "A").Value, 8) = "!JOURNAL" And Not (IsEmpty(cells(x, "H"))) Then
          
            idxblankrow = cells(x, "A").End(xlDown).Row
            MsgBox "Idx blank row is " & idxblankrow 
            Range(cells(x + 2, "A"), cells(idxblankrow - 1, "H")).Cut cells(x + 2, "B")
            'copy the value from "H" on the whole A:A column portion:
            Range("A" & x & ":A" & idxblankrow - 1).Value = cells(x, "H").Value 'not using clipboard...
            
            Stop 'check when stopped here if it did what you need
                 'if so, please press F5 to continue and check again.
            
            'you probably need to increment x to continue iteration after the processed portion
            'something as:
            x = x + (idxblankrow - x) + 2 '???
        End If
Next x

你现在可能需要用已经处理的行数来增加x，但是你必须用语言解释你试图完成什么。猜测不是一种合适的工作方式......

如果我想知道一整行是否为空，我只需要连接整行并检查长度，如果长度为零，那么该行为空，否则，该行就不是空的。
参见下面的示例性屏幕截图（只有第四行是空的，这在第四个公式中可见，结果为零）：

使用标志来标识组的开始和结束。这处理组之间的多个空行。

Sub macro()
   Dim ws As Worksheet
   Dim lastrow As Long, i As Long, n As Long
   Dim x As Long, z As Long
   Dim bStart As Boolean, bEnd As Boolean
   
   Set ws = ThisWorkbook.Sheets("Sheet1")
   n = 0
   With ws
       lastrow = .Cells(.Rows.Count, "A").End(xlUp).Row
       For i = 1 To lastrow
       
            ' start of group
            If Len(.Cells(i, "A")) > 0 Then
                bStart = True
                n = n + 1
            End If
            
            ' end of group look ahead
            If Len(.Cells(i + 1, "A")) = 0 Then
                bEnd = bStart
            End If
            
            ' valid range
            If bStart And bEnd Then
                x = i - n + 1 ' first row of group
                MsgBox "Processing rows " & x & " to " & i
                
                If Left(.Cells(x, "A").Value, 8) = "!JOURNAL" _
                    And Not (IsEmpty(Cells(x, "H"))) Then
                        ' process rows x to i
                End If
                ' reset flags
                n = 0
                bStart = False
                bEnd = False
            End If
                    
        Next
    End With
End Sub

所有这些答案都可以简单得多，想想这个：

iNextBlankRow = Sheet1.Range("A" & iNextBlankRow & ":A50").SpecialCells(xlCellTypeBlanks).Cells(1, 1).Row

要进行演示，请运行以下宏：

Sub BlankRowTest()
    Dim iNextBlankRow As Long
    Dim r As Long
    
    iNextBlankRow = 1
    For r = 1 To 50
        If iNextBlankRow <= r Then iNextBlankRow = Sheet1.Range("A" & iNextBlankRow + 1 & ":A50").SpecialCells(xlCellTypeBlanks).Cells(1, 1).Row
        Debug.Print r, iNextBlankRow, "'" & Sheet1.Cells(r, 1).Value & "'"
    Next
End Sub

这段代码循环遍历前50行，寻找下一个空行，找到后赋给变量iNextBlankRow，直到当前行（r）大于或等于INextBlankRow时才更新变量iNextBlankRow，此时我们再从下一行开始查找。
