Are you wondering how to apply a formula to an entire column in Excel? Read this Excel tutorial until the end to find out the tried and tested methods.

Efficiency, consistency, scalability, and automation are key considerations when working with spreadsheet data. Applying a formula across an entire column or until adjacent data is encountered is often necessary to streamline processes. However, doing so manually can be incredibly time-consuming, especially in Excel where a column can contain up to 1,048,576 cells.

Fortunately, Microsoft Excel offers a range of features, functionalities, and tools to tackle this task efficiently, saving time and effort. In this blog post, I’ll demonstrate multiple techniques within Excel for applying a formula to a whole column, empowering you to analyze your data with ease and precision.

## Using a Shortcut Key

On your Excel dataset, highlight the first cell below the column header and enter your formula.

Now, hit `Enter` to calculate the output of the entered formula.

Highlight the formula cell again and then use `Shift` and `Down Arrow` to highlight the part of the column until the cell where data exists in the adjacent column.

Alternatively, press `Ctrl` + `Shift` + `Down Arrow` to highlight all the cells of the column.

Now, press `Ctrl` + `D` to fill the cells with the formula in the top cell of the column. This action will overwrite any content in the selected cells of the column.

## Using Copy & Paste

Another quick and easy way to fill the whole column with a select formula is the copy-and-paste method.

Firstly, create and enter an Excel formula in the first cell of the column after the column header. Don’t forget to hit `Enter` to calculate the value of the cell.

Now, press `Ctrl` + `C` to copy the cell.

Use `Shift` + `Down Arrow` to select the partial column or `Ctrl` + `Shift` + `Down Arrow` to select the whole column until the 1,048,576th cell.

Press `Ctrl` + `V` to paste the formula. Excel shall automatically calculate the values of the cells where you’ve copied the formula.

## Using the Fill Handle

Another fast method for applying a formula to an entire column in Excel is using the fill handle feature. However, for this technique to work, the adjacent columns to the left of the selected column must contain data up to the 1,048,576th cell. The fill handle tool automatically extends the formula in the selected column until it encounters data in the adjacent columns involved in the calculation.

On your Excel worksheet, navigate to the first column below the target column’s header. There, enter the column you want to paste in the entire column.

Now, highlight the first cell again. You should see a tiny solid square box in the bottom right corner of the selected cell. That’s the fill handle.

**Double-click** on it to copy and paste the formula down the column.

The fill handle has been available since the Excel 2010 desktop app. If you’re using an earlier edition, you can’t use this method.

If you’re on Excel 2010 or a better edition and unable to see the fill handle, press `Alt` + `F` + `T` on the keyboard to bring up the **Excel Options** dialog.

On **Excel Options**, click the **Advanced** category on the left-side panel. Then, checkmark the checkbox for **Enable fill handle…** below the **Editing options** section on the right-side panel. Don’t forget to click **OK** to save the changes you’ve made.

## Using the Fill Down Tool

Fill Down is the Excel ribbon command. If you’re unable to use the `Ctrl` + `D` shortcut key to copy a formula to an entire column, you can use the **Fill Down** tool.

After entering the formula in a cell of the target column, select the cell along with the rest of the cells of the column using the `Ctrl` + `Shift` + `Down Arrow` keys.

Now, go to the **Home** tab and navigate to the **Editing** command block. Click on the **Fill** drop-down arrow and choose the **Down** option from the context menu.

Excel shall fill the whole column with the formula of the selected cell. It’ll also calculate the cells as it copies the formula.

## Using an Array Formula

If you enter an array formula in a cell of a column, Excel will automatically calculate the cells below the formula. Excel will calculate the cells until it encounters a blank cell in the adjacent columns referred to in the selected formula.

In the above dataset, I’m calculating the amount of a 20% discount from MSRP. To do this calculation for all the cells in **column D** (MSRP column), I’ll use an array formula as shown below:

`=D2:D10*20%`

Ensure you adjust the references and values in the formula according to your own dataset.

Upon pressing the `Enter` (`Shift` + `Enter` on older Excel editions) key on the keyboard, Excel will calculate all the cells in the **Discount** column until the last cell where values exist in the adjacent cells.

Now, if your dataset contains referred data in the formula until the 1,048,576th cell, Excel shall calculate the values for all the cells using the same array formula.

A drawback of this method is if someone deletes the parent array formula, all the cells will lose their calculated values.

## Using the Excel Table

Provided that the feature **AutoCorrect Options for Fill formulas in table** is active, Excel will overwrite all the cells in a column, except the header cell will a formula entered in any cell of the said column.

However, this method will only work if you’ve created the table before entering the formula in any column of the cell. Let’s look at how it works.

Suppose you want to calculate the cells in the **Cost** column by referring to the adjacent cells under the **Nos.** and **Rate** columns in the above dataset.

For the calculation, you’re going to use the following formula:

`=B2*C2`

Now, you’re planning to apply the same formula in all the cells of the **Cost** column and calculate the cells in one go.

First, you must convert the dataset to an Excel table. To do so, you’ll highlight any cell on the dataset and press `Ctrl` + `T`. Now, click **OK** on the **Create Table** dialog to create the table object.

Now, copy and paste the above formula into any cell of the **Cost** column and hit `Enter`.

Excel shall overwrite all the cells in this column with this formula and calculate the cells as well.

### Enabling Fill Formulas in Table

AutoCorrect Options for Fill formulas in table have been available since Excel 2007. If you’re using compatible Excel software but are still unable to use this feature to apply a formula to a whole column in Excel, you must enable the feature.

Press `Alt` + `F` + `T` to bring up the **Excel Options** dialog.

On **Excel Options**, click the **Proofing** category on the left and click the **AutoCorrect Options** button.

Now, you should see the **AutoCorrect** dialog. There, checkmark the checkbox for **Fill formulas in table…** feature.

Click **OK** on the **AutoCorrect** and **Excel Options** dialogs to save the changes you’ve just made.

Now, perform the steps mentioned earlier to use AutoCorrect Options for Fill formulas in table.

## Using the AutoCorrect Options in a Table

If you’re unable to enable Fill formulas in table in your Excel desktop app but the software edition supports the feature, you’ll see the AutoCorrect Options as a suggestion in your table if you enter a formula in any column.

Using this suggestion box, you can apply a formula to an entire column in Excel.

Let’s consider that you’ve already created your Excel table using the worksheet dataset.

Now, enter the desired formula in the target column of the table and hit `Enter`.

You shall see a small **AutoCorrect Options** suggestion box to the right of the cell just below the formula cell. Click on that and click on the **Overwrite all cells…** option in the overflow context menu.

Excel shall copy and calculate the formula in all the cells of the target column.

## Using Excel VBA

So far you’ve learned all the techniques to apply one formula to the whole column using various Excel command buttons and shortcuts.

Suppose, you want to automate this task as a part of a larger Excel automation, you can use Excel VBA scripting. Here’s a script that’ll do the following:

- Show an input box so you can select the target column using the mouse.
- The VBA script shall ignore the first cell of the selected column because it might contain a column header.
- It’ll loop through the selected column to detect the formula you want to apply to the entire column from the 2nd cell to the 1048576th cell.
- If the script finds any formula in the column, it’ll copy and paste the same in the entire column.

- The VBA script shall also copy the number formatting of the first formula cell to the rest of the cells of the column.

```
Sub ApplyFormulaToColumn()
Dim rng As Range
Dim cell As Range
Dim formula As String
Dim numFormat As String
' Prompt the user to select a column
On Error Resume Next
Set rng = Application.InputBox("Select a column", Type:=8).EntireColumn
On Error GoTo 0
' If no range is selected, exit the subroutine
If rng Is Nothing Then Exit Sub
' Loop through each cell in the column, starting from the second cell
For Each cell In rng.Cells
If cell.Row > 1 Then
' If the cell has a formula, store it and exit the loop
If cell.HasFormula Then
formula = cell.formula
numFormat = cell.NumberFormat
Exit For
End If
End If
Next cell
' If no formula was found, exit the subroutine
If formula = "" Then Exit Sub
' Apply the formula and number format to the entire column, starting from the second cell
With rng.Cells(2, 1).Resize(rng.Cells.Count - 1, 1)
.formula = formula
.NumberFormat = numFormat
End With
End Sub
```
