Lesson 16: Cells, Ranges, Columns and Rows in VBA for Excel

Many beginners start their career using Cells. For example:
Cells(1,1).Select means (row 1, column 1) and is the same thing as Range("A1").Select and Cells(14,31).Select means (row 14, column 31) and is the same as Range("AE14").Select.

We strongly recommend that you use Range instead of Cells to work with cells and groups of cells. It makes your sentences much clearer and you are not forced to remember that column AE is column 31.

The only time that you will use Cells is when you want to select all the cells of a worksheet. For example:

To select all cells and then empty all cells of values or formulas  you will use: 


To select a single cell you will write:
To select a set of contiguous cells you will use the colon and write:Range("A1:G5").Select
To select a set of non contiguous cells you will use the comma and write:Range("A1,A5,B4").Select
To select a set of non contiguous cells and a range you will use both the colon and the comma:Range("A1,A5,B4:B8").Select


The Offset property is the one that you will use the most with Range to move around the sheet.
To move one cell down (from B2 to B3): Range("B2").Offset(1,0).SelectTo move one cell to the right (from B2 to C2): Range("B2").Offset(0,1).SelectTo move one cell up  (from B2 to B1): Range("B2").Offset(-1,0).SelectTo move one cell to the left  (from B2 to A2): Range("B2").Offset(0,-1).Select
To move one cell down from the selected cell:ActiveCell.Offset(1,0).Select

As you notice the first argument between the parentheses for Offset is the number of rows and the second one is the number of columns. So to move from A1 to G6 you will need:

You will use very often the following piece of code . It selects a cell PLUS 4 more to the right to be copied/pasted somewhere else:
Notice the comma after the first ActiveCell and the double closing parentheses before the Copy.
