EXCEL 自定义函数提取字符串中的数字

自定义函数提取字符串中的数字

Function GetNB(rng As Range)
If rng <> "" Then
For i = 1 To Len(rng)
tmp = Mid(rng, i, 1)
If IsNumeric(tmp) Or tmp Like "[+-\*\/^%)()]" And Not tmp Like "[A-Z?!~@=_,;|\[]" Then GetNB = GetNB & tmp
Next
Else
GetNB = ""
End If
End Function

若使运算式自动计算，则用以下代码

Function CountNB(rng As Range)
If rng <> "" Then
For i = 1 To Len(rng)
tmp = Mid(rng, i, 1)
If IsNumeric(tmp) Or tmp Like "[+-\*\/^%()]" And Not tmp Like "[A-Z?!~@=_,;|\[]" Then CountNB = CountNB & tmp
Next
CountNB = Application.Evaluate(CountNB)
Else
CountNB = ""
End If
End Function
