从一系列单元格中删除非数字字符 [英] Remove non-numeric characters from a range of cells
本文介绍了从一系列单元格中删除非数字字符的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
- 我有一个 1500 行的 Excel 文件.
- 在第一列中,我将字符与数字混合在一起(每一行都不同).
- 我只想留下数字并删除字母字符.
例如在 A1
我有
f90f5j49,35.48
在我删除字母字符后它应该是
and after I delete the alpha characters it should be
905493548
最好的方法是什么?
我确实找到了这个 youtube 解决方案
谢谢!
推荐答案
你的方法是正确的方法.
Your method is the right approach.
实现这一点的最快方法是使用
The quickest way to implement this is to use
- a regexp
- 和 VBA 中的变体数组.
使用基于我的文章的代码 在 Excel VBA 中使用变体数组进行大规模数据操作
Using code based on my Article Using Variant Arrays in Excel VBA for Large Scale Data Manipulation
Sub KillNonNumbers()
Dim rng1 As Range
Dim rngArea As Range
Dim lngRow As Long
Dim lngCol As Long
Dim lngCalc As Long
Dim objReg As Object
Dim X()
On Error Resume Next
Set rng1 = Application.InputBox("Select range for the replacement of non-number", "User select", Selection.Address, , , , , 8)
If rng1 Is Nothing Then Exit Sub
On Error GoTo 0
'See Patrick Matthews excellent article on using Regular Expressions with VBA
Set objReg = CreateObject("vbscript.regexp")
objReg.Pattern = "[^d]+"
objReg.Global = True
'Speed up the code by turning off screenupdating and setting calculation to manual
'Disable any code events that may occur when writing to cells
With Application
lngCalc = .Calculation
.ScreenUpdating = False
.Calculation = xlCalculationManual
.EnableEvents = False
End With
'Test each area in the user selected range
'Non contiguous range areas are common when using SpecialCells to define specific cell types to work on
For Each rngArea In rng1.Areas
'The most common outcome is used for the True outcome to optimise code speed
If rngArea.Cells.Count > 1 Then
'If there is more than once cell then set the variant array to the dimensions of the range area
'Using Value2 provides a useful speed improvement over Value. On my testing it was 2% on blank cells, up to 10% on non-blanks
X = rngArea.Value2
For lngRow = 1 To rngArea.Rows.Count
For lngCol = 1 To rngArea.Columns.Count
'replace the leading zeroes
X(lngRow, lngCol) = objReg.Replace(X(lngRow, lngCol), vbNullString)
Next lngCol
Next lngRow
'Dump the updated array sans leading zeroes back over the initial range
rngArea.Value2 = X
Else
'caters for a single cell range area. No variant array required
rngArea.Value = objReg.Replace(rngArea.Value, vbNullString)
End If
Next rngArea
'cleanup the Application settings
With Application
.ScreenUpdating = True
.Calculation = lngCalc
.EnableEvents = True
End With
Set objReg = Nothing
End Sub
