A “cell reference” means the cell to which another cell refers. Cells in the spreadsheet are referred to by rows and columns. For learning purposes about cell references, we will at times write them as row, column, this is not valid notation in the spreadsheet and is simply meant to make things clearer. Absolute – This means the cell reference stays the same if you copy or move the cell to any other cell.This is done by anchoring the row and column, so it does not change when copied or moved.
For example, you could anchor the row reference then move a cell down two rows and across four columns and the row reference stays the same. Let’s refer to that earlier example – suppose in cell A1 we have a formula that simply says =A2.In this lesson we discuss cell references, how to copy or move a formula, and format cells.To begin, let’s clarify what we mean by cell references, which underpin much of the power and versatility of formulas and functions.A concrete grasp on how cell references work will allow you to get the most out of your Excel spreadsheets!we’re just going to assume that you already know that a cell is one of the squares in the spreadsheet, arranged into columns and rows which are referenced by letters and numbers running horizontally and vertically. Let’s review what we said in Lesson 2 about rows and columns so that we can explore cell references further. The first cell in the spreadsheet is A1, which means column A, row 1, B3 refers to the cell located on the second column, third row, and so on.As you move the cell to the right, the column number increases. The cell that it points to, the cell reference, changes as well.
This is illustrated below: Continuing with our example, and looking at the graphic below, if you copy the contents of cell A1 two to the right and four down you have moved it to cell C5.
We copied the cell two columns to the right and four down.
That means Excel output in cell A1 whatever is inputted into cell A2.
In cell A2 we have typed “A2” so Excel displays the value “A2” in cell A1.
Now, suppose we need to make room in our spreadsheet for more data.
We need to add columns above and rows to the left, so we have to move the cell down and to the right to make room.
