Ever find it difficult to resize an array formula to the right size?
This is some useful VBA to help you work with array formulas on your
worksheets. I've added this to an add-in (Technicana Utilities) and
assigned it to CTRL+SHIFT+A. You can download a copy at
http://technicana.com/vbaSection/TechnicanaAddin.html
Public Sub SetArrayToNaturalSize()
' Resizes an Array formula to its 'natural size', i.e. a range
' big enough to display all of the array formula results
Dim rngCurrent As Range
Set rngCurrent = Selection
' Get the Contents of the Top Left Cell
Dim vContents As Variant
vContents = rngCurrent.Cells(1, 1).Formula
' Clear the current selection
On Error GoTo FailedToClear
ClearRange rngCurrent
' How big do we need to set our target range?
Dim depth As Integer
Dim width As Integer
Dim vResults As Variant
vResults = Application.Evaluate(vContents)
' Check the result is an array
If Right(TypeName(vResults), 2) = "()" Then
' It's an array, but of how many dimensions?
If GetArrayDimensionCount(vResults) = 2 Then
' 2-D Array
depth = UBound(vResults, 1)
width = UBound(vResults, 2)
Else
' 1-D Array
depth = 1
width = UBound(vResults)
End If
Else
' Just a single result
depth = 1
width = 1
End If
' Write our formula back to the Worksheet
Range(rngCurrent.Cells(1, 1), rngCurrent.Cells(1, 1).Offset(depth -
1, width - 1)).FormulaArray = vContents
Exit Sub
FailedToClear:
MsgBox Title:="Failed to clear the selected range.", _
Prompt:="This can be caused by the presence of another
array function within the bounds of the selection"
Exit Sub
Exit Sub
End Sub
