**A Brief Overview of Array Formula in Excel**

**Excel array formula** is one such feature that can execute multiple calculations over single or multiple numbers of items in the array. You can consider this array as the combination of value’s rows and columns. Array formulas can give you single or multiple results in return.

The array formula which has multiple cells is known as a multi-cell formula. Whereas, the array formula present in the single-cell is known as the single-cell formula.

**What Does It Mean When Excel Says You Cannot Change Part of An Array?**

The error specifies that you’re trying to edit or modify a portion of the array, which is not allowed. However, the array formulas involve consistency & integrity in their structure. Any alteration must be applied to the whole array, not just the subset of its elements.

**Root Causes of the Error:**

**Array Dependencies-**The array formulas are interrelated with each other, and changing one part without considering others can cause an error.**Mismatched Functions:**Certain functions & formulas may not be compatible with an array, triggering the error unexpectedly.**Data Validation:**The existence of data validation rules can restrict changes, resulting in you can’t change part of an array Excel error.

**How to Fix Excel You Can’t Change Part Of An Array Error?**

Try the below step-by-step workarounds to fix this error.

**Method 1- Match The Syntax**

Usually, the array formulas strictly follow the **standard formula syntax**. It starts with an equal sign. In the array formulas, you can use the Excel built-in functions. So, press the **Ctrl + Shift + Enter** keys to enter the formula.

Excel closes the array formula within the braces. But if you manually add these braces then the array formula will get converted to the text string and this won’t work correctly.

To build a complex formula, Array functions are quite an efficient option to choose from.

Suppose you are using a complex formula like this:

**=SUM(C2*D2,C3*D3,C4*D4,C5*D5,C6*D6,C7*D7,C8*D8,C9*D9,C10*D10,C11*D11)**.

So instead of using the above complex formula, you can use the **array formula** **=SUM(C2:C11*D2:D11 )**

- After that press the
**Ctrl+Shift+Enter**button from your keyboard. - If in case, you are entering the multi-cell array formula then choose the entire cell having this formula and then press the F2 button. after that mentioned set of rules:
- You are not allowed to move individual cells having the formula, but as a group, you can all of them at once. Ding this will automatically change the formula cell references accordingly.

To shift this to a new place, choose the entire cell and press the Ctrl+X. Choose any new location, where you want to paste it. After that make press the Ctrl+V button.

- In the array formula, you can’t delete any cells if you are trying to do so then it’s obvious to get the

**Method 3- Use Ctrl+Shift+Enter**

It is the basic and most important component of array formulas which you need to enter by using the Ctrl+Shift+Enter.

Here are the steps to create an array formula:

- Choose cells that contain the array formula.
- Assign the formula either by typing or using the formula bar.
- After completing all these, enter the formula and then type
**Ctrl+Shift+Enter.** - Just put the formula within the array.

**Method 4- Evaluate the Array Formula**

Microsoft Excel offers an excellent feature known as “**Evaluate Formula**” that help you to step through the formula to check the intermediate results. You can even use this feature to deal with this error.
