In a spreadsheet or worksheet, data is organized into rows and columns.

Rows are numbered numerically from top to bottom while Columns are referred by alpha characters from left to right. In Excel 2007, there are 65536 Rows which are numbered as 1, 2, 3, … 65,536. These numbers are shown on the left most portion of the worksheet. Columns Columns (total 256 in Excel) are identified by letters, such as A, B, C,.. AA… IV, and are shown on the horizontal box just above Row 1. Thus, there are 65,536 x 256 = 1,65,00,000, approximately cells, which is indeed a huge work area, sufficient for all application requirements in one sheet.
