In Excel and other spreadsheets, a relative cell reference identifies the location of a cell or group of cells.
By default, a spreadsheet cell reference is relative. What this means is that as a formula or function is copied and pasted to other cells, the cell references in the formula or function change to reflect the function's new location.
In contrast, an absolute cell reference does not change when it a formula is copied and pasted to other cells.
An example of a relative cell reference would be C4, G15, or Z2345.
Note: When listing a cell reference - either relative or absolute, the column letter is always listed first.
