What does the SUMIF function do?

The SUMIF function in Excel is used to calculate the sum of cells that meet a single condition. It's a handy tool when you need to add up specific values within a range of data based on a certain criteria.

Here's a breakdown of how it works:

* Syntax: `=SUMIF(range, criteria, [sum_range])`

* Arguments:

* `range`: This is the cell range containing the values you want to evaluate. It must include numbers or cells with numbers.

* `criteria`: This defines the condition for selecting cells. It can be a number, text, expression, a cell reference containing the criteria, or a function that evaluates to TRUE or FALSE. Wildcards (* and ?) can be used for partial text matching.

* `[sum_range]`: This argument is optional. By default, it uses the `range` argument. However, you can specify a different range of cells to sum if the values you want to add reside elsewhere in your worksheet.

For example, let's say you have a list of sales data in column A and product names in column B. You want to find the total sales for a specific product, say "Apples." You can use the following formula:

`=SUMIF(B2:B10, "Apples", A2:A10)`

This formula will:

1. Look at the range B2:B10 (product names).

2. Check if each cell value in that range matches the criteria "Apples" (case-sensitive).

3. If a match is found in column B, the corresponding value in the same row from column A (sales data) will be included in the sum.

4. Finally, it will add up all the sales figures that meet the criteria ("Apples").

The SUMIF function is a great way to automate calculations and summarize data based on specific conditions within your Excel spreadsheets.
