Convert to hrs:min

[da]

hello
Is there any way to convert the following numbers to show as hrs:min without
manually insterting a colon?
e.g.15:45 18:40

1545 1840
2015 2300
2045 2105
1700 1815
1825 1840
1850 2000
1835 1900

Select the cells you want to convert and run this little macro:

Sub marine()
Dim hrs As Integer, mins As Integer
For Each r In Selection
v = r.Value
hrs = Left(v, 2)
mins = Right(v, 2)
r.Clear
r.NumberFormat = "hh:mm"
r.Value = TimeSerial(hrs, mins, 0)
Next
End Sub

Thank you for your suggestion. I am not good at runnung macros.
But I found another formula that worked.
