How do I create a dynamic array in Excel VBA?

Dynamic Array

First, we declare the array named numbers.
Next, we determine the size of the array and store it into the variable size.
We now know the size of the array and we can redimension it.
Next, we initialize each element of the array.
We display the last element of the array using a MsgBox.

Can you have an array of arrays in VBA?

“Jagged array” is slang for array of arrays. VBA’s Variant data type can contain just about anything*, including an array. So you make an array of type Variant , and assign to each of its elements an array of arbitrary length (i.e. not all of them have to have equal length).

The ReDim statement is used to size or resize a dynamic array that has already been formally declared by using a Private, Public, or Dim statement with empty parentheses (without dimension subscripts). You can use the ReDim statement repeatedly to change the number of elements and dimensions in an array.

How do you create a multidimensional array?

Creating Multidimensional Arrays You can create a multidimensional array by creating a 2-D matrix first, and then extending it. For example, first define a 3-by-3 matrix as the first page in a 3-D array. Now add a second page. To do this, assign another 3-by-3 matrix to the index value 2 in the third dimension.
