循环使用VBA修剪单元

Question

我试图使用修剪功能没有成功。 在此论坛和其他在线资源上搜索解决方案后，我发现了许多不同的方法。

在VBA中没有修整单元格的简单方法吗？

我想要的是这样的：

Sub trimloop()

Dim row As Integer

row = 1

Do While Cells(row, 1) <> ""

   Cells(row, 2) = trim(Cells(row, 2))

   row = row + 1

Loop

因此，当A（1）列中有值时，B（2）列中的值应修剪掉多余的空格。 我只是无法让它为我工作。

感谢任何帮助/提示！

Answer 1

所以我使代码有点准确和防错，并且有效。

因此，我建议您仔细检查一下，如果您具有正确的行和列值，因为您可能定位到错误的单元格。 （因为您的代码有效）

Sub trimloop()

Dim row As Integer
Dim currentSheet As Worksheet
Set currentSheet = sheets("Sheet1")

row = 2

Do While currentSheet.Cells(row, 1) <> ""

   currentSheet.Cells(row, 2).Value = Trim(currentSheet.Cells(row, 2).Value)

   row = row + 1

Loop

End Sub

Answer 2

使用Application.WorksheetFunction.Trim(string)

Sub trimloop()

Dim row As Integer

row = 1

With ThisWorkbook.ActiveSheet
Do While .Cells(row, 1) <> ""

   .Cells(row, 2) = Application.WorksheetFunction.Trim(.Cells(row, 2))

   row = row + 1

Loop
End With
End Sub

如果是大数据表，这是代码的优化版本：

Option Explicit

Sub trimloop()

Dim row As Long, max As Long
Dim Data() As Variant

With ThisWorkbook.Sheets(1)

    max = .Cells(1, 1).End(xlDown).row 'this does the same as your code, on first empty cell it stops
    'the following finds the last un-empty cell of column(1):
    'max= .cells(.rows.count,1).end(xlup).row

    'copies values from sheet to memory (is faster for working with later)
    Data = .Range(.Cells(1, 1), .Cells(max, 2)).Value2

    'loop :
    For row = 2 To max + 1

        'work with memory instead of sheet
        Data(row, 2) = Trim(Data(row, 2))
        'for complete delete of all spaces use : = replace( StringName," ", "")

    Next row

    'write back to sheet
    .Range(.Cells(1, 1), .Cells(max, 2)).Value2 = Data

End With

erase Data 'free memory

End Sub

不知道这是否过于简化...但是我想我只是把它扔出去，对我有用。 唯一的先前步骤是为工作簿/工作表/数据集分配“命名范围” ...命名数据集，然后使用此代码遍历数据集

Sub forEachLoop()
    For Each cell In Range("yourNamedRange")
        cell.Value = Trim(cell.Value)
    Next cell
End Sub
