I WANT A RESULT Deepak shown BOLD
You will need to convert this to text first. It can be done with a macro, but more info is needed to suggest good design.
Sub putemtogetherandbold()
mybreak = Len(Range("a1")) + 1
Range("a3") = Range("a1") & "-" & Range("a2")
Range("a3").Characters(mybreak, 256).Font.Bold = True
End Sub
