COLUMNS function

PRO

The COLUMNS function in Jspreadsheet Formulas Pro is a tool that provides the total number of columns within a selected range or array. For example, if you have a table of data and you want to know how many columns it contains, you would use this function. It's as simple as inputting the range of cells into the function, and it will return the count of columns. This is particularly useful in data analysis when you need to work with large datasets.

Documentation

Returns the number of columns in a range or array.

Syntax

COLUMNS(array)

Parameter	Description
`array`	The range or array of cells for which you want to count the number of columns.

Behavior

The COLUMNS function is used to return the number of columns in a given cell range. It takes a range as an argument and outputs an integer representing the total number of columns within that range. Here's how it handles various scenarios:

Empty Cells: If the range includes empty cells, these cells are still counted as columns by the COLUMNS function. Each column in the range is counted regardless of whether the individual cells within it are empty or contain data.
Text: If the range includes cells with text, the COLUMNS function will still count these cells as columns. The type of data in the cells does not affect the function's output.
Booleans: Like text and numbers, Boolean values (TRUE/FALSE) are also counted as columns by the COLUMNS function.
Errors: If the range includes cells with errors, these cells are also counted as columns by the COLUMNS function. However, if the specified range is invalid or non-existent, the function will return an error.

Common Errors

Error	Description
#VALUE!	Occurs when the argument is not a proper range or array (e.g., a plain number or string).
#REF!	This error happens when the range specified in the function refers to a location that is not valid. This could be a cell that doesn't exist, or a range that has been deleted or moved.

Best practices

Always ensure that the range you specify in the COLUMNS function is valid and exists in your spreadsheet. This will help you avoid errors.

Remember that COLUMNS returns the count of columns, not the number of populated cells or values within those columns.. So, if you need to count cells with data, consider using a different function.

When using COLUMNS function in a formula, remember that it returns the total number of columns in a range, not the column index. If you need the column index, you might need to adjust your formula.

Be aware that the COLUMNS function will count all columns in the range, including those with errors, text, or Boolean values. Make sure this is what you want before using the function.

Usage

A few examples using the COLUMNS function.

COLUMNS(A1:D5) returns 4  
COLUMNS(A1:C1) returns 3
