MAKEARRAY function

PRO

The MAKEARRAY function in Jspreadsheet Formulas Pro is a tool that allows you to create an array, which is essentially a structured set of data, with dimensions that you specify. This means you can decide how many rows and columns your array should have. Additionally, you have the option to fill up this array with a certain value of your choice, or leave it empty. This function is particularly useful in handling and organizing large volumes of data.

Documentation

Creates an array of specified dimensions and fills it with either a specified value or no value.

Syntax

MAKEARRAY(rows, columns, function)

Parameter	Description
`rows`	The number of rows in the array.
`columns`	The number of columns in the array.
`function`	The LAMBDA function to apply for generating the array values.

Behavior

The MAKEARRAY function generates an array of specified dimensions, filled with a specific value or formula. Here are some behaviors to note:

Empty Cells: If the dimensions point to empty cells, MAKEARRAY will create an array filled with null values. The function does not automatically fill empty cells with a default value.
Text: MAKEARRAY can generate an array filled with text values if the value or formula argument is a text string.
Booleans: If the value or formula argument is a boolean (TRUE or FALSE), MAKEARRAY will create an array filled with that boolean value.
Errors: If the dimensions are not valid (e.g., negative numbers, non-integer values), or if the array size exceeds the range limit supported by Jspreadsheet, MAKEARRAY will return an error.
Numbers: MAKEARRAY can generate an array filled with numeric values if the value or formula argument is a number.

Common Errors

Error Name	Description
#VALUE!	This error occurs if the dimensions provided are not valid (e.g., negative numbers, non-integer values).
#REF!	This error occurs if the generated array exceeds the range limit of the spreadsheet software.

Best practices

Here are some best practices when using MAKEARRAY:

Use the MAKEARRAY function to initialize large arrays with a specific value or formula instead of filling them in manually.

Be aware that MAKEARRAY will fill in empty cells with null values. If this is not desired, ensure you provide a value or formula argument.

Use clear and descriptive names for the ranges you create with MAKEARRAY to make your spreadsheets easier to understand and maintain.

Usage

A few examples using the MAKEARRAY function.

MAKEARRAY(3, 2, MyLambdaFunction) returns a 3x2 array by applying MyLambdaFunction to each element.  
MAKEARRAY(2, 2, AnotherLambda) returns a 2x2 array by applying AnotherLambda to each element.  
MAKEARRAY(4, 4, SomeOtherLambda) returns a 4x4 array by applying SomeOtherLambda to each element.
