Count and sum cells that match conditions: COUNTIF and SUMIF
The COUNTIF and SUMIF functions calculate their values based on search criteria. The search criteria can be a number, expression, text string, or even a regular expression. The search criteria can be contained in a referenced cell or it can be included directly in the function call.
The COUNTIF function counts the number of cells in a range that match specified criteria. The first argument to COUNTIF specifies the range to search and second argument is the search criteria. Table 7 illustrates different search criteria using the COUNTIF function referencing the data shown in Table 1.
The first two arguments for SUMIF serve the same purpose as the arguments for COUNTIF; the range that contains the cells to search and the search criteria. The third and final argument for SUMIF specifies the range to sum. For each cell in the search range that matches the search criteria, the corresponding cell in the sum range is added into the sum.
