The cell range that starts in cell A1 and goes over J15 is written in formula as

In Excel, the notation for a range of cells is expressed as a string that includes the address of the top-left cell and the bottom-right cell, separated by a colon. In your case, the top-left cell of the range is A1, and the bottom-right cell of the range is J15.

Cell Range Formula

The formula for the specified cell range from A1 to J15 is:

$\text{A1:J15}$

Explanation

This notation indicates that the range includes all cells from A1 (the first cell in the first column) to J15 (the last cell in the tenth column of the fifteenth row). This range encompasses a rectangular block of cells that totals 150 individual cells (10 columns × 15 rows). In Excel and similar spreadsheet applications, this range can be utilized for various functions such as SUM, AVERAGE, or applying formatting to multiple cells simultaneously, making it a powerful feature for data manipulation and analysis.

Thus, whenever you want to reference or operate on this block of data, you would use the range "A1:J15".
