Detailed explanation-1: -Columns are identified by letters (A, B, C), while rows are identified by numbers (1, 2, 3). Each cell has its own name-or cell address-based on its column and row. In the example below, the selected cell intersects column C and row 5, so the cell address is C5.
Detailed explanation-2: -Columns are designated by letters while rows are designated by numbers.
Detailed explanation-3: -By default, Excel uses the A1 reference style, which refers to columns as letters (A through IV, for a total of 256 columns), and refers to rows as numbers (1 through 65, 536). These letters and numbers are called row and column headings. To refer to a cell, type the column letter followed by the row number.
Detailed explanation-4: -How are columns and rows labeled? 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.
