In Excel: select the cells, then grab the small green square at the bottom-right corner — the fill handle — and drag it down or across to copy values or extend a series; double-click it to fill down to the end of the adjacent data.

Enter enough values to define the pattern (one cell to copy, two cells for a series).
Select those cells so the fill handle appears at the bottom-right.
Drag the handle down or across, or double-click it to fill down to the end of the adjacent data.
Click the AutoFill Options button to pick Copy Cells, Fill Series, or Fill Formatting Only.
Use Ctrl+D to fill down or Ctrl+R to fill right without dragging.
What this does
The fill handle is the small green square at the bottom-right corner of a selection. Dragging it copies the selected cells or extends a detected series, and double-clicking it fills down to the bottom of the data in the neighboring column. AutoFill reads the pattern in what you selected — 1, 2, 3… or Jan, Feb… — and continues it. Ctrl+D fills the selection down from the cell above; Ctrl+R fills right. After a drag, the AutoFill Options button appears so you can switch between Copy Cells, Fill Series, and Fill Formatting Only. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “drag a column in excel”. Start on a copy or a tiny sample, keep the affected columns visible, and compare the result with the tool above before you touch the real workbook. When this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. The point is a layout choice that keeps the sheet readable and sortable, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
Type 1 in A1 and 2 in A2, select both cells, then drag the fill handle down — Excel reads the step of 1 and continues 3, 4, 5… If you instead dragged a single cell containing 1, it would copy 1, 1, 1 until you switch to Fill Series. Dragging the fill handle is the fastest way to repeat a value or build a numbered or dated series down a column without typing each cell. When the result is not what you expected, undo straight away rather than repairing it by hand — undo restores the sheet exactly, while manual fixes tend to leave small inconsistencies behind that surface later.
In Google Sheets
This is a command rather than a formula, so there is no syntax to carry over. Google Sheets arranges its commands in menus across the top instead of a ribbon, names some of them differently and does not have every Excel command — look for the equivalent in the Sheets menus or its help before assuming the steps match. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. The short version of “drag a column in excel”: the answer is at the top of this page, and the sections above explain why each step matters, so a variation of the problem does not stump you. Try it once on a copy of a real file and the steps stick far better than re-reading them.
Common mistakes
- Dragging one cell and expecting a series — a single cell copies; give it two cells to set the step.
- Double-clicking the handle when the adjacent column has gaps, so the fill stops early.
- Ignoring the AutoFill Options button when Excel guessed copy instead of series.
- Holding the wrong corner — the move pointer (four arrows) drags the cell, not the fill handle.
Frequently asked questions

How do I fill down without dragging?
Select the range and press Ctrl+D to fill down, or Ctrl+R to fill right.
Why does my drag copy instead of counting up?
