# Excel formula for Beginners – How to Sum matching columns and rows in Excel

In this end-to-end excel example, you will learn – Excel formula for Beginners – How to Sum matching columns and rows in Excel.

### Generic formula

`=SUMPRODUCT(data*(range1=criteria1)*(range2=criteria2))`

### Explanation

To sum values in matching columns and rows, you can use the SUMPRODUCT function. In the example shown, the formula in J6 is:

`=SUMPRODUCT(data*(codes=J4)*(days=J5))`

where data (C5:C14), days (B5:B14), and codes (C4:G4) are named ranges.

### How this formula works

The SUMPRODUCT function can handle arrays natively, without requiring control shift enter.

In this case, we are multiplying all values in the named range data by two expressions that filter out values not of interest. The first expression applies a filter based on codes:

`(codes=J4)`

Since J4 contains “A002”, the expression creates an array of TRUE FALSE values like this:

`{FALSE,TRUE,FALSE,FALSE,FALSE}`

The second expression filters on day:

`(days=J5)`

Since J4 contains “Wed”, the expression creates an array of TRUE FALSE values like this:

`{FALSE;FALSE;TRUE;FALSE;FALSE;FALSE;FALSE;TRUE;FALSE;FALSE}`
