Lesson Summary. This lesson discussed the different types of cell references in Excel. You learned that cell references can be relative, absolute or mixed. The type you use in a formula is important, as each behaves differently when copied or moved.
Absolute references An absolute cell reference in a formula, such as $A$1, always refer to a cell in a specific location. If the position of the cell that contains the formula changes, the absolute reference remains the same.ou can also use a reference style where both the rows and the columns on the worksheet are numbered. The R1C1 reference style is useful for computing row and column positions in macros. In the R1C1 style, Excel indicates the location of a cell with an R followed by a row number and a C followed by a column number.
