**What Is Array Formula In Excel?**

The

Array Formula in Excelperforms multiple calculations on the dataset values of rows, columns, or a cell range. It returns single or multiple results as required in the formula.

One **Array Formula in Excel** replaces multiple formulas that enable users to apply standard Excel functions to several cells quickly. And all formulas in the selected array range will be the same, so they ensure consistency. For example, the following table shows the annual salary and increment details from 2015 to 2020.

We will calculate the total earnings during the six years and display the output in cells **D2:D7** using the **Array Formula in Excel**. Select cells **D2:D7**, enter the formula **=B2:B7+C2:C7,** and press the keys **Ctrl+Shift+Enter, **the final formula will automatically change to **{=B2:B7+C2:C7}** within curly brackets.

The output is shown above in Column D, as we had selected cell range D2:D7.

**How To Use Array Formula in Excel?**

We can use **Array Formula in Excel** in two ways:

**Single-cell Formula**– The input can be a single array or multiple arrays, but the result will be a single-cell output since one cell is selected for the output.**Multi-cell Formula**– The input can be a single array or multiple arrays, but the output is displayed in the selected cell range.

**#Basic Example**

The following example will help us in **understanding Array Formulas in Excel, **with the monthly income and expense. We will find the total savings made during the year.

In the table, the data is,

- Column A contains the Months.
- Column B contains the Monthly Income.
- Column C contains the Monthly Expenses.

The steps to find the total savings made during the year using the **Array Formula in Excel** are:

__Step 1__**: **Select cell **B15** and enter the formula** =SUM(B2:B13-C2:C13).**

__Step 2__**: **Press the shortcut keys **Ctrl+Shift+Enter** to execute the **Array Formula**.

The output is shown above. The final formula appears within curly brackets in the **Formula Bar**.

**Examples**

Let us understand **Array Formulas in Excel** with some advanced scenarios.

**#Example 1**

The following illustration explains a single cell output. We will compare steps to find the output using the **Standard Excel **and an **Array Function**. We will find the lowest difference in units sold between the first half and second half of a year,

In the following table, the data is,

- Column A contains the Smartphones.
- Column B contains the Jan to Jun Units Sold.
- Column C contains the Jul to Dec Units Sold.
- Columns D, H, and I for the outputs.

The steps to find the lowest difference using the **Standard Excel function **are:

** 1: **Choose cell

**D2,**enter the formula

**=C2-B2,**and press the “

**Enter**” key. [This will determine the difference in the units sold between the two durations for the first smartphone in cell

**A2**].

** 2: **Drag the formula using the fill handle from cell

**D2**to

**D10**.

** 3: **Next, choose cell

**G2**to enter the

**MIN()**formula

**and press the “**

*=MIN(D2:D10)***Enter**” key. We will get the output as shown in the image below.

** 4: **Now

**,**to determine the smartphone model with the least units sold difference, choose cell

**H2**and enter the formula

*=INDEX(A2:A10,MATCH(MIN(D2:D10),D2:D10,FALSE),1)*We will get the output as shown above. [i.e., The smartphone model that has the lowest difference in units sold between the first half and second half of a year].

Now, let us use the other method.

The steps to find the lowest difference using the **Array Formulas in Excel** are:

Now, when we use **Array Formulas** in Excel, the steps will be:

**Step** ** 1: **Choose cell

**G3**and enter the formula

*=MIN(C2:C10-B2:B10).***Step** ** 2: **Press the shortcut keys

**Ctrl+Shift+Enter**to complete the action.

The two arrays, **B2:B10** and **C2:C10**, are the input. And the expression **{=MIN(C2:C10-B2:B10)} **first calculates the unit sold difference for each smartphone model and then determines the least value among them i.e., **-1952**.

**Step** ** 3:** Drag the formula using the fill handle in cell

**H2**to

**H3,**or we can copy the formula. The output will be as shown in the image below.

**Note the Observation**:

- When applied as a standard Excel function, the
**MIN()**takes three tedious steps to determine the required value. - When we use it as an
**Array Formula, we only enter the function in the target cell G3 directly instead of calculating the values of column D**. Within two steps, we get the result].

**#Example 2**

We will now see how the **Array Formulas in Excel** work when the output is for multiple cells.

In the following table, the data is,

- Column A contains the Student Names.
- Column B contains the English Scores.
- Column C contains the Credits Out of 20.
- Column D contains the Overall English Score.

The steps to determine the overall English score for each using the **Array Formula in Excel** are:

__Step 1__**: **Select the cell range **D2:D11** and enter the formula *=B2:B11+C2:C1.*

__Step 2__**: **Press the **Array Formulas in Excel** shortcut keys **Ctrl+Shift+Enter** to execute the formula.

The output is shown above. The Excel array function, **{=B2:B11+C2:C11}**, takes two arrays, **B2:B11,** and **C2:C11**, as the input. It then adds the English score and credits for each student and displays the individual total scores for the ten students in the cell range **D2:D11 **i.e., multiple cell range output.

**#Example 3**

One of the best **examples of Array Formulas in Excel** with multiple arrays as input and output is using the **TRANSPOSE() function** for the following population data.

In the table below, the data is,

- Column A contains the Country.
- Column B contains the Rank.
- Column C contains the Population.

The steps to use the **Array Formulas in Excel** and the **Transpose()** function are as follows:

** 1: **Choose cell range

**A9:F11**to display the transposed table. [

**Note:**The target table’s rows-columns cell counts should match the source table’s columns-rows cell counts, i.e., here source table is (

**3**columns *

**6**rows) =

**18 cells**, so selected range for target table is (

**3**rows *

**6**columns) =

**18**cells].

** 2: **Now, enter the formula

*=TRANSPOSE(A1:C6).*** 3: **Press the shortcut keys,

**Ctrl+Shift+Enter**, to execute the function as an

**Array Formula**. The output is shown in the image below.

When using multi-cell array functions, we must remember the below points while **updating Array Formulas in Excel.**

- Choose the target cell range where we want to display the output and then enter the formula.
- The selected target cell range should have the correct size. Otherwise, a smaller selection will not display the entire output, while a larger selection will return an
**#N/A error.** - To remove a multi-cell array function, choose the entire cell range where we applied the formula and press
**Delete**. Alternatively, we can select the formula in the**Formula Bar**, press**Delete**, and then press the keys**Ctrl+Shift+Enter**together. - If we want to update the formula to apply it to fewer target cells, delete the command and enter the new function with the required cell range.
- While
**updating Array Formulas in Excel**to apply them to new cells, select all the existing and the new cells and enter into the edit mode. Then type in the command with the updated cell range and press the Excel array function keyboard shortcut to apply the updated array function. - The multiple arrays output scenario does not work when using Excel tables. Also, we cannot edit the data in the cells referenced in the multi-cell
**Array Formula**.

**Using F9 To Evaluate Array Formula**

We will use the function key **F9 To Evaluate Array Formula** for the total expenses incurred from the seafood purchase.

In the following table, the data is,

- Column A contains the Seafood.
- Column B contains the Units Bought.
- Column C contains the Price Per Unit.

Also, the two arrays, **B2:B7** and **C2:C7**, are the input. The formula **{=SUM(B2:B7*C2:C7)} **in cell **E2** first calculates the total amount spent on each item and then adds all the values to determine the total expenses, **927**.

The steps to understand the internal evaluation of the above calculation using the **F9** key are:

__Step 1__**: **Choose the required arguments we want to evaluate in the array function i.e., in the **Formula Bar,** select cell **E2** formula arguments **B2:B7*C2:C7**.

__Step 2__**: **Now, press the **F9** key to see how the arguments evaluate to give the final output.

The **Formula Bar **shows how the chosen terms calculate the product of units bought and the respective price per unit for each item. The **SUM() **Excel function then adds these products to determine the final output.

[**Note: **Ensure we select the part of the array function we want to evaluate and press **F9**. Otherwise, if we place the cursor on the formula and press **F9**, the key will replace the formula with the value we determined. To exit the **Array Formulas** in Excel evaluation process, we need to press the **Esc** key].

**Important Things To Note**

**Array Formulas in Excel**help execute multiple calculations and process values in a single cell or multiple cells.- Select the correct target cell range when the output is in multiple arrays to avoid incorrect results.
- If we want to edit an
**Array Formula**,

- Delete the function and re-enter it.
- Update the new cell references in the function in the edit mode and press
**Ctrl+Shift+Enter**to execute the command. - If we get a
**#Value!**error, so go again and press**Ctrl+Shift+Enter**to execute and exit.
