Complete Theory & Understanding

Master the fundamentals of Excel MAKEARRAY function

Core Concept

The MAKEARRAY function creates a calculated array of specified dimensions using a LAMBDA function. It is useful for generating arrays with specific patterns or calculations.

Why Use MAKEARRAY?

  • MAKEARRAY generates arrays based on row and column indices passed to a LAMBDA function
  • MAKEARRAY requires a LAMBDA function that takes row and column indices as parameters
  • MAKEARRAY returns a dynamic array that automatically resizes based on the specified dimensions

Key Characteristics

Array Generation

MAKEARRAY generates arrays based on row and column indices passed to a LAMBDA function

Example 1

LAMBDA Integration

MAKEARRAY requires a LAMBDA function that takes row and column indices as parameters

Example 2

Dynamic Arrays

MAKEARRAY returns a dynamic array that automatically resizes based on the specified dimensions

Example 3

Function Anatomy

=MAKEARRAY(parameters...)
Required
Parameters:

Function-specific parameters

Returns
Return Value:

Function-specific return type

VBA Implementation & Automation

MAKEARRAY VBA Example

VBA implementation for MAKEARRAY.

Sub MAKEARRAYExample()
    Dim result As Variant
    ' Note: MAKEARRAY is not available in VBA, use alternative methods
    ' This is a conceptual example
    result = Application.WorksheetFunction.MakeArray(3, 3, "LAMBDA(r, c, r*c)")
    MsgBox "MAKEARRAY result: " & result
End Sub
