## What are the requirements to create a dynamic array with item reduction in Excel?

Among the advantages that Excel offers is the creation of a dynamic matrix . This is used to return values ​​to adjacent cells caused by an overflow. This occurs when a formula has returned multiple values ​​that have been placed in adjacent cells. In order to reduce items, Excel offers you several formulas that will help you reduce them and organize your data more efficiently.

## What formulas should you use to make a dynamic array in an Excel spreadsheet?

Current versions of Excel for making a dynamic array determine if there is the ability to return multiple values. In previous versions it was called a legacy CSE formula and only returned one value, could not be resized, and had no spill border.

We recommend that when sharing spreadsheets , users have the same dynamic recognition features. The first step is to use the dynamic array formula compatibility checker. Dynamic matrix formulas are very useful when we use a two-variable data table  and we need to reduce items to facilitate their analysis.

### With the formula ‘C2:C11*D2:D11’

Using array formulas in your Excel spreadsheet will make it easier for you to manage. Mainly, they give you access to do calculations on columns and rows simultaneously. For example, you can put dynamic array formulas in one range of cells and get the subtotals in another range of columns. In the case of the formula “C2:C11*D2:D11”, you can apply it to calculate the sum of data in three columns and combine the results.

Let’s say you have data on 5 employees who sold two different types of products with different prices. Empty that data into the Excel sheet and type the formula “=SUM(C2:C11*D2:D11)” and Excel will calculate the grand total. To get the grand total for each product select the cell range of the two products and type “= C2:C11*D2:D11” and press “ctrl+shift+enter”. And to get the grand total of all sales type “=SUM(C2:C11*D2:D11)” and press “ctrl+shift+enter”.

### Using the formula ‘=ORDER(D2:D11,1,-1)’

This formula is suitable for data overflow . If you use the formula “=SORT(D2:D11,1,-1)” to sort an array in descending order, the data will be returned to an array 10 rows high. Just copy the formula and it will automatically overflow to cell F11. Confirming the formula by pressing enter will adjust the range size and dynamically place the data in that cell.

Overflowed array formulas are not supported in your own tables so you will have to design a pivot table with dynamic range in Excel . This tool gives you the opportunity to summarize, analyze and compare trends and patterns in your data. You can create it by following these steps:

2. Select a cell and click on the “insert” tab.
3. Click pivot table.
4. In “create pivot table” press accept.
5. Another spreadsheet will be created.
6. Displays “PivotTable Field List”.
7. Check the box to add them to the report and they will be reflected on the sheet.
8. By exchanging the data: row labels, columns, values ​​and report filters the table will organize your data.

## What is the process to create the dynamic array with item reduction in Excel?

The first step in organizing and viewing a data set for statistical analysis is to dump it into your Excel spreadsheet. The dynamic array will help you access them quickly.

Let’s take as an example your interest in observing the relationship of four variables such as age, bank balance, academic degree and marital status. The first two data are numerical represented by quantities, the following are categories represented by 1 number that will correspond to a comment (1 for married, 2 for single and 3 for divorced).

After emptying all this information, you can use the data validation tool to generate a list of values ​​that reduces the number of items using the formulas “=ORDER(D2:D11,1;-1 or C2:C11*D2:D1. With them based on data overflow, you can achieve the reduction of possible answers by reducing them in an organized way without repeating them unnecessarily.

## How to know if the matrix that you created in Excel was made correctly?

One way to verify that a matrix was made correctly is by consulting data in an Excel sheet with the function CONSULTAV . When in doubt, use this function to search for data vertically. You must know a basic value to do your search .

This value can refer to the exact category of the search or be linked to the cell that contains it. Another argument to use this function is the range of the column where you want to see the result. If these match it is proof that you made your matrix correctly.
