Using Counta in Excel 2010

The COUNTA function counts the number of cells that are not empty in a range (range: Two or more cells on a sheet. The cells in a range can be adjacent or nonadjacent.).

Syntax

COUNTA(value1, [value2], ...)

The COUNTA function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

  • value1    Required. The first argument representing the values that you want to count.
  • value2, …    Optional. Additional arguments representing the values that you want to count, up to a maximum of 255 arguments.

Remarks

  • The COUNTA function counts cells containing any type of information, including error values and empty text (“”). For example, if the range contains a formula that returns an empty string, the COUNTA function counts that value. The COUNTA function does not count empty cells.
  • If you do not need to count logical values, text, or error values (in other words, if you want to count only cells that contain numbers), use the COUNT function.
  • If you want to count only cells that meet certain criteria, use the COUNTIF function or the COUNTIFS function.

Using the Countif Function in Excel 2010

Countif Counts the number of cells within a range that meet the given criteria.

Syntax

COUNTIF(range,criteria)

Range    is the range of cells from which you want to count cells.

Criteria    is the criteria in the form of a number, expression, cell reference, or text that defines which cells will be counted. For example, criteria can be expressed as 32, “32”, “>32”, “apples”, or B4.

Remarks

  • 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.
  • Microsoft Excel provides additional functions that can be used to analyze your data based on a condition.
    • To calculate a sum based on a string of text or a number within a range, use the SUMIF worksheet function.
    • To have a formula return one of two values based on a condition, such as a sales bonus based on a specified sales amount, use the IF worksheet function.
    • To count cells that are empty or not empty, use the COUNTA and COUNTBLANK functions.
