Load Variant Arrays From Ranges Using the Evaluate Function

The Evaluate function provides a fast way to load a variant array from any adjacent range of cells. The resulting variant arrays are always 2 dimensional when two or more cells are loaded. The code examles below show various ways to load a Variant array.

Program Code

Option Explicit
' *******************************************************************
' All of the examples below in which the range is more than one cell
' create a 2-dimensional Variant array where:
'    The first dimension is the row number relative to 1
'    The second dimension is the column number relative to 1
'
' For example:
'    varArray1 = Evaluate("=[" & ThisWorkbook.Name & "]Sheet1!E5:G14")
'    Creates varArray1 with these dimensions:
'    varArray1(1,1) through varArray1(10,3)
'
' To Test The Upper Bounds use this command in the Immediate Area
'    ? UBound(varArray1,1)  'First Dimension of Rows
'    ? UBound(varArray1,2)  'Second Dimension of Columns
