提取Excel中两个字符之间的字符串

Question

theStr =“KT150”

字符总数总是5。我想确保在Str中有3个数字。我如何在Excel VBA中实现这一点？

Answer 1

精确副本

你的问题是一点点在缺少细节，但如何：

Sub test() 

    Debug.Print containsXnumbers("KT150", 3) 

End Sub 

Function containsXnumbers(sInput As String, xNumbers As Long) As Boolean 

    Dim x As Long 
    Dim numCount As Long 

    For x = 1 To Len(sInput) 
     If IsNumeric(Mid(sInput, x, 1)) Then numCount = numCount + 1 
    Next x 

    If numCount = xNumbers Then containsXnumbers = True 

End Function 

Answer 2

这应有助于：

Function onlyDigits(s As String) As String 
    ' Variables needed (remember to use "option explicit"). ' 
    Dim retval As String ' This is the return string.  ' 
    Dim i As Integer  ' Counter for character position. ' 

    ' Initialise return string to empty      ' 
    retval = "" 

    ' For every character in input string, copy digits to  ' 
    ' return string.          ' 
    For i = 1 To Len(s) 
     If Mid(s, i, 1) >= "0" And Mid(s, i, 1) <= "9" Then 
      retval = retval + Mid(s, i, 1) 
     End If 
    Next 

    ' Then return the return string.       ' 
    onlyDigits = retval 
End Function 

例子：

Dim myStr as String 
myStr = onlyDigits ("3d1fgd4g1dg5d9gdg") 
MsgBox (myStr) 

将返回（在消息框中）：

Answer 3

你不需要VBA得到一个字符串的位数，但这里是一个方法来计算他们：

Public Function KountNumbers(r As Range) As Long 
    Dim i As Long, t As String 

    t = r.Text 
    For i = 1 To Len(t) 
     If Mid(t, i, 1) Like "[0-9]" Then KountNumbers = KountNumbers + 1 
    Next i 
End Function 

例如：

没有VBA试试这个：

=SUMPRODUCT(LEN(A1)-LEN(SUBSTITUTE(A1,{0,1,2,3,4,5,6,7,8,9},""))) 

获得数字的数量。

Answer 4

尝试使用以下公式

假设您的数据在A1中。应用下面的公式B1

=IF(AND(LEN(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(A1,"1",""),"2",""),"3",""),"4",""),"5",""),"6",""),"7",""),"8",""),"9",""),"0",""))=2,LEN(A1)=5),"3 character numerals","No 3 numerals found")
