No. A column is identified by the letters at the top of the window.
In Microsoft Excel, the letters in the last column are represented by combinations of the letters A to Z. Once you reach the letter Z in the column headers, the next column will be labeled AA, AB, AC, and so on. This pattern continues with BA, BB, BC, and so forth, allowing for a virtually unlimited number of columns in Excel.
Columns are designated by letters or combinations of letters. The first is Column A, then B, then C and so on. After Column Z, the next is AA, then AB and so on. Depending on what version of Excel you have, the last column is either Column IV, which is the 256th column, or Column XFD, which is the 16,384th column.
Column IV is not the last column in Excel 2007, as it was in Excel 2003. In Excel 2003 the last column is IV which is column 256. In Excel 2007 the last column is XFD, which is column 16384.
The letters in the heading above a worksheet grid are called column names.
