Dim xValue As Variant
On Error Resume Next
xTitleId = "KutoolsforExcel"
Set WorkRng = Application.Selection
Set WorkRng = Application.InputBox("Range", xTitleId, WorkRng.Address, Type:=8)
For Each Rng In WorkRng
    xValue = Rng.Value
    xHours = VBA.Split(xValue, ".")(0)
    xMin = VBA.Split(xValue, ".")(1) * 60
    Rng.Value = xHours & ":" & VBA.Left(xMin, 2)
Next
End Sub
