When the program starts, an empty workbook appears on the screen, which is a set of three sheets (by default), each of which has a table. The rows of the table are numbered from 1, and the columns are denoted in Latin letters, starting with A. In total, more than 65 thousand rows and more than 250 columns are placed on the sheet. Excel spreadsheets consist of cells designated by type A1, where A is the column designation, 1 is the row designation. You can also select a block of cells. For example, A1: C4 is a designation of a set of cells that fall into a rectangular region, the corners of which are cells A1 and C4.
Formatting characters in cells is very similar to a text editor, only Excel has fewer parameters that can be changed. All cell manipulations can be performed using the "Format Cells" dialog.
