It returns the sum of all the cells in a given range that meet a specific criterion.

The syntax of the function is the following:

SUMIF(range, criterion, [sum_range])range: The cells or range of cells we want to calculate the sum for, unless the sum_range argument is defined. If the optional attribute sum_range is defined then range is the range to which we apply the criterion.criterion: It is the criterion that defines which cells of the range should be included in the calculation of the sum.[sum_range]: Optional. The actual set of cells to sum. If this argument is omitted the range attribute is used.

If the cells in range are empty or contain logical or text values they are ignored.

If a criterion cell is empty, it is treated as a zero.

You can use the wildcard characters, question mark (?) and asterisk (*), in criteria. A question mark matches any single character; an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.
