MAP function

PRO

The MAP function in Jspreadsheet Formulas Pro is used to apply a certain formula or function to every individual cell within a specific range, and it then provides the results in the form of a new array. This allows for mass calculations to be done across a data set, saving you the time and effort of doing each calculation independently. Simply put, it is a way of applying the same operation to many cells at once, and then collecting all the results.

Documentation

Applies a formula or function to every cell in a range and returns the results as a new array.

Syntax

MAP(array, formula)

Parameter	Description
`array`	The range of cells that you want to apply the formula to.
`formula`	The formula or function that you want to apply to each cell in the array. The formula can reference the current cell with a dot (.) or the entire array with square brackets ([]).

Behavior

Empty cells: The MAP function will treat them as zeros.
Text: If the MAP function is designed to work with numerical data, it will return an error if a cell containing text is included in the range of cells it is mapping over.
Booleans: The MAP function treat boolean values as 1 (for TRUE) and 0 (for FALSE).
Errors: If one of the cells in the range that the MAP function is mapping over contains an error, the MAP function will return an error.

Common Errors

Error Name	Description
#VALUE!	This error occurs when one or more of the cells in the range that the `MAP` function is mapping over contains a type of data (such as text or a boolean value) that the `MAP` function can't handle.
#REF!	This error occurs when one of the cell references in the range that the `MAP` function is mapping over is not valid (for example, if the cell has been deleted).
#NUM!	This error occurs when the `MAP` function encounters a number that it can't handle (for example, a number that's too large or too small).

Best practices

Always check the data types in the cells that the MAP function will be mapping over. Make sure they are compatible with the function's requirements.

Use error handling functions to catch and handle any errors that may occur when using the MAP function.

If possible, avoid using the MAP function on large ranges of cells as it may slow down your spreadsheet's performance.

Usage

A few examples using the MAP function.

MAP(A1:A5, LAMBDA(x, x*2)) applies the formula x*2 to each cell in the range A1:A5 and returns the resulting array
