On Error Resume Next
xTxt = ActiveWindow.RangeSelection.Address
Set xRg = Application.InputBox("Pease select range:", "Kutools for Excel", xTxt, , , , , 8)
If xRg Is Nothing Then Exit Sub
Set xRegEx = CreateObject("VBScript.RegExp")
.Pattern = "\D+"
.IgnoreCase = True
.Global = True
xRg.NumberFormat = "@"
For Each xCell In xRg
xCell.Value = xRegEx.Replace(xCell.Value, "")
