Excel is the most popular application mostly for official purposes. Professionals who work with large amounts of data easily rely on Excel. With the help of Excel, we can organize data smoothly. Lots of functions are used in Excel for different purposes. This article is all about the** SUMPRODUCT function**. We will discuss how to use the **SUMPRODUCT function **across multiple sheets. So, let’s begin.

**Introduction to Excel SUMPRODUCT Function**

The Excel **SUMPRODUCT **function multiplies the cells of range or arrays and sums them together. If we elaborate 1st it will multiply the elements of a range. Then it will give a sum of the multiplied elements.

**Purpose**

Multiply, then sum arrays/ranges

**Syntax**

**=SUMPRODUCT (array1, [array2], …)**

**Arguments**

* array1 *– The first array or range to multiply, then add.

* array2 *– [optional] The second array or range to multiply, then add.

**Return value**

The result of multiplied and summed arrays/ranges

**Notes:**

The **SUMPRODUCT **function multiplies arrays or ranges together and returns the sum of products. If a single array is supplied, **SUMPRODUCT **will simply sum the items in the array. We can supply up to **30** arrays or ranges.

At the first glance, **SUMPRODUCT **may seem boring, complex, and even pointless. But **SUMPRODUCT **is an amazingly versatile function with many uses. Because it will control arrays nicely. We can use it to process ranges of cells in clever, elegant ways.

In this topic, we will use **SUMPRODUCT **across multiple sheets in Excel. We will discuss two methods in this regard. All the processes will be shown here.

**2 Methods to Use SUMPRODUCT Function Across Multiple Sheets in Excel**

We take a data set of a stationary shop 1st *3* months of *2021* in three different sheets. Here, we have used the * Microsoft Excel 365* version.

**1. Applying with SUMIF and INDIRECT Functions**

In this section, we will use the **INDIRECT **and **SUMIF **functions along with the **SUMPRODUCT **function.

**Introduction to INDIRECT Function**

The** INDIRECT function** returns the reference specified by a text string. References are immediately evaluated to display their contents. We use it when we want to change the reference to a cell within a formula without changing the formula itself.

**Syntax**

**INDIRECT(ref_text, [a1]**

**Arguments**

* Ref_text *– A reference to a cell that contains an A1-style reference, an R1C1-style reference, a name defined as a reference, or a reference to a cell as a text string. If ref_text is not a valid cell reference,

**INDIRECT**returns the #REF! error value.

** a1 –** A logical value that specifies what type of reference is contained in the cell ref_text. If a1 is

**TRUE**or omitted, ref_text is interpreted as an A1-style reference. If a1 is

**FALSE**, ref_text is interpreted as an R1C1-style reference.

**Introduction to SUMIF Function**

The** SUMIF function** adds the cells specified by a given condition or criteria.

**Syntax**

**SUMIF(range, criteria, [sum_range])**

**Arguments**

** range –** It defines the range of cells that we want. Cells in each range must be numbers or names, arrays, or references that contain numbers.

** criteria – **The criteria may be a number, expression, cell reference, text, or function. It defines which cells will be added.

**SUMPRODUCT with INDIRECT & SUMIF**

Now, we will show the process of **SUMPRODUCT **with the **INDIRECT **function across multiple sheets.

**Steps:**

- Firstly, modify the data set. add the sheet names in the Month section on
**Sheet1**.

- Secondly, go to cell
**C5**. and write down the formula. So, the formula is:

`=SUMPRODUCT(SUMIF(INDIRECT("'"&$B$11:$B$13&"'!$B$5:$B$8"),B5,INDIRECT("'"&$B$11:$B$13&"'!$C$5:$C$8")))`

- Consequently, press the
**ENTER**button.

**Formula Breakdown:**

In the formula, we used the absolute reference so that the reference doesn’t change. We listed the sheet names from **B11 **to **B13** and used them in the formula. Range** B5 to B8** is used to match the product name of the reference sheets with present sheets cell **B5 to B8**. And **C5 to C8** is used to return the value of the reference sheets.

- Finally, pull down the
**Fill Handle**icon from cell**C5**to**C8.**

Now, get the final result. It is the sum of all three months of different elements.

**2. SUMPRODUCT with SUM function Across Multiple Sheets**

**SUMPRODUCT **can be applied with **the SUM function** across multiple sheets.

**Introduction to SUM Function**

The** SUM function** adds values. We can add individual values, cell references or ranges, or a mix of all three.

**Syntax**

**SUM(number1,[number2],…)**

**Argument**

** number1 – **This is the first number we want to add. This can be any single number, cell reference, or cell range.

* number2 *– This is the second number that we want to add. We can add up to 255 numbers in this way.

**SUMPRODUCT with SUM Function**

Now, we will show the steps to apply **SUMPRODUCT** with **SUM** across multiple sheets.

**Steps:**

- Firstly, go to cell
**C5**of Sheet 2**SUM**and**SUMPRODUCT**functions. - Secondly, we will go to the worksheet
*Jan*.

- Moreover, after going to sheet
**Jan,**select range**B5**to**B8.**

- However, move to
**Sheet2.**and compare to cell**B5.** - Apparently, close the bracket.
- Sequentially, put a
**multiplication(*) sign.**Thus, again go to the worksheet*Jan*. - Eventually, select the range
**C5:****C8.**

- Similarly, add
and**Feb**sheets and complete the formula*Mar***.**So, the formula becomes:

`=SUM(SUMPRODUCT((Jan!B5:B8=Sheet2!B5)*(Jan!C5:C8)),SUMPRODUCT((Feb!B5:B8=Sheet2!B5)*(Feb!C5:C8)),SUMPRODUCT((Mar!B5:B8=Sheet2!B5)*(Mar!C5:C8)))`

Here, the **SUM **function is used to sum the **SUMPRODUCT **results. First, we find out the **SUMPRODUCT **for each sheet. Then we add them using the **SUM **function.

- Finally, press
**ENTER.**and drag down the**Fill Handle**icon from cell**C5**to**C8**and get the final return.

Now, get the result for all the cells.
