删除单元格范围内的非数字字符

1. 我有一个1500行的excel文件。
2. 在第一列中，我将字符与数字混合在一起（每一行都不相同）。
3. 我只想留下数字并删除字母字符。

例如在A1我有

f90f5j49,35.48

并删除后，应该是字母字符

905493548

做这个的最好方式是什么？

我find了这个YouTube解决scheme

谢谢！

你的方法是正确的做法。

实现这个最快的方法是使用

• 一个正则expression式
• 和VBA中的变体数组。

使用代码基于我的文章在Excel VBA中使用Variant数组进行大规模数据处理

 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
