Detailed explanation-1: -What is a column in Excel? Columns are denoted and identified by a unique alphabetical header letter, which is located at the top of the worksheet. Column headers range from A-XFD, as Excel spreadsheets can have 16, 384 columns in total. Columns run vertically in the worksheet, and the data goes from up to down.
Detailed explanation-2: -A column is a vertical series of cells in a chart, table, or spreadsheet. Below is an example of a Microsoft Excel spreadsheet with column headers (column letter) A, B, C, D, E, F, G, and H. As you can see in the image, the last column H is highlighted in red, and the selected cell (D8), is in the D column.
Detailed explanation-3: -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-4: -Items in row are aligned from left to right, while columns are aligned from top to bottom. A row is a horizontal alignment of data, while a column is vertical.
