COUNT function

PRO BASIC

The COUNT function in Jspreadsheet Formulas Pro is a useful tool that helps you determine the number of cells within a specified range that contain numerical values. This function scans through your selected range and only counts cells that have numbers, ignoring those with text, blank cells, or cells with non-numerical data. This can be especially useful in large datasets where manual counting would be time-consuming and prone to errors. By using the COUNT function, you can easily and accurately keep track of numerical data in your spreadsheets.

Documentation

Counts the number of cells in a range that contain numbers.

Syntax

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

Parameter	Description
`value1`	The first value or range of cells to count.
`valueN`	Optional. Additional values or ranges of cells to count. You can enter up to 255 arguments.

Behavior

The COUNT function is used to count the number of numerical data entries within a specified range. Here is how it behaves with different data types:

Empty Cells: COUNT ignores empty cells and does not include them in the count.
Text: COUNT does not count cells that contain text. This includes cells with numbers in quotes, which are considered text.
Booleans: COUNT ignores Boolean values (TRUE/FALSE) entirely—they are not treated as numbers and are not included in the count.
Errors: If an error occurs in a cell within the range, COUNT will typically ignore it and not include it in the count.
Dates: COUNT will count cells containing dates, as they are stored as numbers in spreadsheets.

Common Errors

Error	Description
#VALUE!	This error occurs when the function is given the wrong type of argument, such as a string of text.
#REF!	This error is displayed when the function refers to an invalid cell reference.

Best Practices

Always ensure that the range of cells you are counting primarily contains numeric data, as COUNT is designed to handle numbers. If you need to count cells with text, consider using COUNTA.

Check that your referenced cells or ranges are valid to avoid #REF! errors.

Be aware that COUNT includes cells with zero and negative numbers in the count.

If you need to count logical or error values, use COUNTA or COUNTIF as an alternative.

Usage

A few examples using the COUNT function.

COUNT(A1:A10)         // Counts how many cells in A1 to A10 contain numeric values  
COUNT(A1, B1, C1, D1)  // Counts how many of these four cells contain numbers  
COUNT(1, "text", TRUE, "", 5)  // Returns 2 – counts only 1 and 5 (TRUE is ignored)
