Two ways you can use Evaluate to generate a reference to a Range object, and assign a value to that object

 
Sub evalDemo()
     Evaluate("A1").value = 10
     [A1].value = 10
End Sub

1.	Fill formula to cell
2.	Inserts a formula in cell A11 of a worksheet that calculates the sum of the values in the range A2:A10 using the Excel application's SUM function
3.	Use [] to evaluate formula
4.	Is active cell empty
5.	The Evaluate method can also be used with arrays.
6.	Assigns the values 101 to 200 to the range B1:B100, and again does it more efficiently than a For...Next loop
7.	Use Copy and Paste or AutoFill functions
8.	Create a set of related formulas in a column: use a looping structure to iterate through the cells that receive the formula
