What is a variant array VBA?
Arrays are a variant type variable that you can use in VBA coding to store a list of data. Think of it as a mini-spreadsheet inside of a single variable. You store data into an array by referring to a reference number that corresponds with the location that the piece of data is positioned in.
What is a dynamic array in VBA?
Dynamic arrays can be resized at run-time using the “ReDim” statement. These are also known as Variable Arrays or Variable-Length Arrays. This type of array is very useful when you don’t know the exact size of the array at design time. Before you can use a dynamic array you must define an initial number of elements.
How do I set dynamic range in VBA?
- First, we declare one variable and two Range objects.
- We add the line which changes the background color of all cells to ‘No Fill’.

- Reduce the number of lines using Colon(:)
Why do we use ReDim?
Remarks. You can use the ReDim statement to change the size of one or more dimensions of an array that has already been declared. If you have a large array and you no longer need some of its elements, ReDim can free up memory by reducing the array size. The ReDim statement is intended only for arrays.
What is a dynamic range in VBA?

What is the function of dynamic arrays?
Summary Dynamic Arrays will make certain formulas much easier to write. You can now filter matching data, sort, and extract unique values easily with formulas. Dynamic Array formulas can be chained (nested) to do things like filter and sort. Formulas that return more than one value will automatically spill.
