**Excel 2010 VBA 113 bytes**

I am assuming paragraph spacing is 1 byte. This wont work with earlier versions of Excel

    n = 14925
    Do While n > 0
    c = ((n - 1) Mod 26)
    s = Chr(c + 65) & s
    n = (n - c) \ 26
    Loop
    Debug.Print s

*Boring VBA answer, 24 bytes*

    Debug.Print UCase("vba")
