Excel Functions COUNTIFS, SUMIFS, and AVERAGEIFS INDEX and MATCH Date/Time Functions Text Manipulations

COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2]…) The COUNTIFs function Syntax: COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2]…) Arguments: criteria_range1    Required. The first range in which to evaluate the associated criteria. criteria1    Required. The criteria in the form of a number, expression, cell reference, or text that define which cells will be counted. For example, criteria can be expressed as 32, ">32", B4, "apples", or "32". criteria_range2, criteria2, ...    Optional. Additional ranges and their associated criteria. Up to 127 range/criteria pairs are allowed.   IMPORTANT   Each additional range must have the same number of rows and columns as the criteria_range1argument. The ranges do not have to be adjacent to each other.

The COUNTIFs function Description: Remarks: Errors: Applies criteria to cells across multiple ranges and counts the number of times all criteria are met. Remarks: Each range's criteria is applied one cell at a time. If all of the first cells meet their associated criteria, the count increases by 1. If all of the second cells meet their associated criteria, the count increases by 1 again, and so on until all of the cells are evaluated. If the criteria argument is a reference to an empty cell, the COUNTIFS function treats the empty cell as a 0 value. You can use the wildcard characters— the question mark (?) and asterisk (*) — in criteria. A question mark matches any single character, and an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character. Errors: None

The COUNTIFs function

The SUMIFs function Syntax: SUMIFS(sum_range, criteria_range1, criteria1, [criteria_range2, criteria2], ...) Arguments: sum_range    Required. One or more cells to sum, including numbers or names, ranges, or cell references that contain numbers. Blank and text values are ignored. criteria_range1    Required. The first range in which to evaluate the associated criteria. criteria1    Required. The criteria in the form of a number, expression, cell reference, or text that define which cells in the criteria_range1 argument will be added. For example, criteria can be expressed as 32, ">32", B4, "apples", or "32." criteria_range2, criteria2, …    Optional. Additional ranges and their associated criteria. Up to 127 range/criteria pairs are allowed.

The SUMIFs function Description: Adds the cells in a range that meet multiple criteria. For example, if you want to sum the numbers in the range A1:A20 only if the corresponding numbers in B1:B20 are greater than zero (0) and the corresponding numbers in C1:C20 are less than 10, you can use the following formula: =SUMIFS(A1:A20, B1:B20, ">0", C1:C20, "<10") IMPORTANT   The order of arguments differ between the SUMIFS and SUMIF functions. In particular, thesum_range argument is the first argument in SUMIFS, but it is the third argument in SUMIF. If you are copying and editing these similar functions, make sure you put the arguments in the correct order

The SUMIFs function Remarks: Each cell in the sum_range argument is summed only if all of the corresponding criteria specified are true for that cell. For example, suppose that a formula contains two criteria_range arguments. If the first cell ofcriteria_range1 meets criteria1, and the first cell of criteria_range2 meets critera2, the first cell ofsum_range is added to the sum, and so on, for the remaining cells in the specified ranges. Cells in the sum_range argument that contain TRUE evaluate to 1; cells in sum_range that contain FALSE evaluate to 0 (zero). Unlike the range and criteria arguments in the SUMIF function, in the SUMIFS function, each criteria_rangeargument must contain the same number of rows and columns as the sum_range argument. You can use the wildcard characters — the 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. Errors: None

The SUMIFs function

The AVERAGEIFs function Syntax: AVERAGEIFS(average_range, criteria_range1, criteria1, [criteria_range2, criteria2], ...) Arguments: Average_range Required. One or more cells to average, including numbers or names, arrays, or references that contain numbers. Criteria_range1, criteria_range2, … Criteria_range1 is required, subsequent criteria_ranges are optional. 1 to 127 ranges in which to evaluate the associated criteria. Criteria1, criteria2, ... Criteria1 is required, subsequent criteria are optional. 1 to 127 criteria in the form of a number, expression, cell reference, or text that define which cells will be averaged. For example, criteria can be expressed as 32, "32", ">32", "apples", or B4.

The AVERAGEIFs function Description: Returns the average (arithmetic mean) of all cells that meet multiple criteria. Remarks: If average_range is a blank or text value, AVERAGEIFS returns the #DIV0! error value. If a cell in a criteria range is empty, AVERAGEIFS treats it as a 0 value. Cells in range that contain TRUE evaluate as 1; cells in range that contain FALSE evaluate as 0 (zero). Each cell in average_range is used in the average calculation only if all of the corresponding criteria specified are true for that cell. Unlike the range and criteria arguments in the AVERAGEIF function, in AVERAGEIFS each criteria_range must be the same size and shape as sum_range. If cells in average_range cannot be translated into numbers, AVERAGEIFS returns the #DIV0! error value. If there are no cells that meet all the criteria, AVERAGEIFS returns the #DIV/0! error value. 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. Errors: None.

The AVERAGEIFs function

The INDEX function Syntax: =INDEX(array,row_num,[column_num]) Arguments: array Required A range of cells or an array constant. row_num Optional Selects the row in array from which to return a value. If row_num is omitted, column_num is required. column_num Optional Selects the column in array from which to return a value. If column_num is omitted, row_num is required.

The DATE function Description: Remarks: Errors: Returns the sequential serial number that represents a particular date. Remarks: If the cell format was General before the function was entered, the result is formatted as a date instead of a number. Excel interprets the year argument according to the date system your computer is using. By default, Microsoft Excel for Windows uses the 1900 date system; Microsoft Excel for the Macintosh uses the 1904 date system. Excel stores dates as sequential serial numbers so that they can be used in calculations. Errors: None

The DATE function What is the serial date for the date in A2:C2, using the 1900 date system? =DATE(A2,B2,C2) =39448

The DATE function What is the result of evaluating =DATE(119,2,19)? Answer: 2/19/2019

The NOW function Syntax: =NOW() Arguments: None

The NOW function Description: Remarks: Errors: Returns the serial number of the current date and time. Remarks: If the cell format was General before the function was entered, Excel changes the cell format to the same date and time format that is specified in the regional date and time settings in Control Panel. The NOW function is useful when you need to display the current date and time on a worksheet or calculate a value based on the current date and time, and have that value updated each time you open the worksheet. Numbers to the right of the decimal point in the serial number represent the time; numbers to the left represent the date. The results of the NOW function change only when the worksheet is calculated or when a macro that contains the function is run. It is not updated continuously. Errors: None

The NOW function =NOW()

The NOW function =NOW()

The TODAY function Syntax: =TODAY() Arguments: None

The TODAY function Description: Remarks: Errors: Returns the serial number of the current date. Remarks: If the cell format was General before the function was entered, Excel changes the cell format to Date. If you want to view the serial number, you must change the cell format to General or Number. The TODAY function is useful when you need to have the current date displayed on a worksheet, regardless of when you open the workbook. The TODAY function is dependent on your computer’s system clock being correct. Errors: None

The TODAY function =TODAY()
