Adding numbers automatically to a column in Excel can be done in two ways, using the ROW function or the Fill feature. The first method ensures that the cells display the correct row numbers even when rows are added or deleted. The second, and easier method, works just as well but you'll need to redo it whenever you add or delete a row in order to keep the numbers accurate. The method you choose is based on your comfort with using Excel and what you're using the application for, but each one is straightforward and will have your sheet organized in no time.

  1. This method explains how to make each cell in a column display its corresponding row number. [1] This is a good method to use if rows are frequently added and removed in your worksheet.
  2. If the cell is not A1, use the correct cell number.
    • For example, if you are typing in cell B5, type =ROW(B5) instead.

  3. The cell will now display its row number. If you typed =ROW(A1) , the cell will say 1 . If you typed =ROW(B5) , the cell will read 5 . [2]
    • To start with 1 no matter which row you want to begin your series of numbers, count the number of rows above your current cell, then subtract that number from your formula.
    • For example, if you entered =ROW(B5) and want the cell to display a 1, edit the formula to say =ROW(B5)-4 , as B1 is back 4 rows from B5. [3]
  4. This box is called the Fill Handle. When the mouse cursor is directly above the Fill Handle, the cursor will change to a crosshair symbol.
    • If you don’t see the Fill Handle, navigate to File > Options > Advanced and place a check next to “Enable fill handle and cell drag-and-drop.”
  5. The cells in the column will now display their corresponding row numbers.
    • If you delete a row included in this series, the cells numbers will automatically correct themselves based on their new row numbers.

  1. This method will show you how to add a series of continuous numbers to the cells in a column.
    • If you use this method and later have to delete a row, you will need to repeat the steps to renumber the entire column. If you think you will be manipulating rows of data often, see Numbering Rows instead.
  2. For instance, if you will be numbering entries down a column, type 1 into this cell.
    • You don’t have to start with 1. Your series can start at any number, and can even follow other patterns (such as even numbers, in multiples of 5, and more).
    • Excel also supports other types “numbering,” including dates, seasons, and days of the week. To fill a column with the days of the week, for example, the first cell should say “Monday.”
  3. This should be the cell directly beneath the currently active cell.
  4. To number consecutively (1, 2, 3, etc), type a 2 here. [4]
    • If you wanted your continuous numbers to be something like 10, 20, 30, 40, etc, the first two cells in the series should be 10 and 20 .
    • If you are using days of the week, type the next day of the week into the cell.
  5. When you release the mouse button, the both cells will be highlighted.
  6. This box is called the Fill Handle. When the mouse pointer is directly on top of the Fill Handle, the cursor will become a crosshair symbol.
    • If you don’t see the Fill Handle, navigate to File > Options > Advanced and place a check next to “Enable fill handle and cell drag-and-drop.”
  7. Once you release the mouse button, the cells in the column will be numbered according to the pattern you established in the first two cells.

    Why does Autonumber repeat the sequence rather than fill down when I drag down?
    Community Answer
    After dragging down, there is an icon next to the last cell that gives you options of whether you want to copy cells or fill series. Click the intended option.
