Detailed explanation-1: -What Is An Absolute Reference? In Excel, an absolute reference is a cell reference in which the column and row coordinates stay constant while copying a formula from one cell to the other. A dollar symbol ($) is used before the coordinates to correct them. For instance, $D$2 is an absolute reference to cell D2.

Detailed explanation-2: -A cell reference refers to a cell or a range of cells on a worksheet and can be used in a formula so that Microsoft Office Excel can find the values or data that you want that formula to calculate.

Detailed explanation-3: -By default, a cell reference is a relative reference, which means that the reference is relative to the location of the cell. If, for example, you refer to cell A2 from cell C2, you are actually referring to a cell that is two columns to the left (C minus A)-in the same row (2).

Detailed explanation-4: -To reference a cell or range of cells in another worksheet in the same workbook, put the worksheet name followed by an exclamation mark (!) before the cell address. For example, to refer to cell A1 in Sheet2, you type Sheet2!A1.

Detailed explanation-5: -These are called “relative” cell references, since they change relative to where you copy the formula. If you do not want cell references to change when you copy a formula, then make those cell references absolute cell references. Place a “$” before the column letter if you want that to always stay the same.
