Each cell in the array formula calculates the result for *a specific combination of product and region*. Consequently, this capability *enhances the efficiency* of *data analysis and decision-making processes*.

### 2. Aggregating Data from Different Ranges

*Aggregating data* from different ranges in Excel allows you to **consolidate information** from multiple sources. This can be helpful for creating **summary reports** or *analyzing large sets of data*. By using functions like SUM, AVERAGE, or **COUNT**, you can perform *calculations* on data from different ranges and obtain the desired results. By using *array formulas*, you can extend these calculations to multiple rows or columns, making data aggregation even more efficient. With the right use of Excel’s features, **aggregating data** from different ranges becomes a *breeze*, providing valuable insights for **decision-making** and *analysis*.

### 3. Filtering Data based on Multiple Criteria

To efficiently filter data based on multiple criteria in Excel, you can follow these simple steps:

- Start by selecting the desired range of data.
- Navigate to the “Data” tab and locate the “Filter” feature.
- Activate the filter by clicking on the filter icon found in the column header.
- Choose the desired column by clicking on the drop-down arrow and select either
*Filter by Color*or*Text Filters*to add your criteria. - For further specificity, you can add more criteria by either utilizing the
*Add Criteria*button or employing logical operators such as*AND*or*OR*. - Excel will then exhibit only the rows that meet all the selected criteria.

Here is how the table will look after filtering:

Criteria | Filtered Data |

Region: West |
Sales > 1000 |

Product: A |
Quantity < 10 |
