In all spreadsheet programs including Microsoft Excel, rows are labeled using numbers (e.g., 1 to 1,048,576). All columns are labeled with letters starting with the letter A and then incrementing by a letter after the final letter Z. For example, after the letter Z, the next column is AA, AB, AC, ..., AZ and then incrementing to BA, BB, BC, etc. all of the way to the last column XFD. When working with a cell, you combine the column with the row. For example, the very first cell is in column A and on row 1, so the cell is labeled as A1.
A spreadsheet program such as Microsoft Excel is specifically designed for creating, managing and presenting information in tabular format. A new spreadsheet is simply a large table with blank cells in which the user can enter information. Spreadsheets are more versatile than word processors in terms of their ability to manipulate large numbers of rows and columns of information. For example, spreadsheets can convert data in tabular format to detailed pie charts, line charts or other types of graphs.
