    How It Works

    Each Excel column letter corresponds to a number: A=1, B=2, … Z=26, AA=27, … XFD=16384. This calculator converts your starting column to its number, adds the offset, then converts the result back to a letter.

    A positive offset moves right (e.g. B+3=E), while a negative offset moves left (e.g. E−3=B). The result must stay within the valid Excel range of column A (1) to XFD (16,384).

    This is useful when working with the OFFSET function, building dynamic column references, or navigating large spreadsheets.
