A worksheet is organized into a grid of cells, which are formed by the intersection of rows and columns.
Rows are identified by numbers. Row numbers can range from 1 to 1,048,576.
Column labels are identified by letters and start with A to Z. After Z, the next column heading is AA, AB, AC, and so forth. The last possible column label is XFD, which means there are 16,384 columns in a worksheet.
The total number of possible cells in a single worksheet is more than 17 billion. That is just one worksheet!!
