In Excel, what does the term "cell reference" refer to?

A cell reference in Excel refers to the address of a cell in a worksheet, which is typically indicated by a combination of letters and numbers. For example, the cell reference "A1" refers to the cell located at the intersection of column A and row 1. Cell references are essential for creating formulas and functions, as they allow users to refer to the values contained in other cells within calculations. When writing a formula, referencing other cells enables dynamic calculations; if the data in the referenced cells change, the formula automatically updates to reflect those changes. This functionality is crucial for data analysis and helps maintain accuracy throughout a spreadsheet.

The other choices focus on different aspects of Excel but do not accurately define the term "cell reference." The color code assigned to a cell pertains to formatting rather than its address. A formula used within a cell represents the calculations or functions applied, rather than the cell's address itself. Lastly, a unique identifier for a worksheet usually refers to the worksheet name or ID within a workbook, which is not synonymous with the concept of a cell reference.
