Prompt:I have a table with sales data, including the salesperson's name in column A, the product category in column B, the sales amount in column C, and the date of sale in column D. I want to calculate the total sales amount for each salesperson, but only for sales of products in the "Electronics" category that occurred in the month of January. Can you help me with the Excel formula to achieve this?

## Sample response

To calculate the total sales amount for each salesperson for sales of products in the "Electronics" category that occurred in the month of January, you can use the following array formula in Excel:

```
=SUMIFS(C:C, A:A, "Salesperson's Name", B:B, "Electronics", MONTH(D:D), 1)
```

Let's break down the formula:

`SUMIFS`

: This is a function that calculates the sum of a range based on multiple criteria.`C:C`

: This is the range of sales amounts (column C) that we want to sum.`A:A`

: This is the range of salesperson names (column A) that we'll use as one of the criteria.`"Salesperson's Name"`

: This is the specific salesperson's name for whom we want to calculate the total sales amount.`B:B`

: This is the range of product categories (column B) that we'll use as another criterion.`"Electronics"`

: This is the specific product category (Electronics) for which we want to calculate the total sales amount.`MONTH(D:D)`

: This extracts the month component from the date of sale (column D).`1`

: This represents January, as January is the first month of the year.

The `SUMIFS`

function evaluates each row in the specified ranges and includes in the sum only those rows that meet all of the given criteria (salesperson's name, product category, and sale date in January).

Please note that this formula should be entered as an array formula by pressing `Ctrl + Shift + Enter`

after typing it into the formula bar in Excel. Also, ensure that the cell references and criteria match the layout of your actual data table.
