## What is Spreadsheet Excel

Excel is a spreadsheet program developed by Microsoft. It is a popular spreadsheet program mostly used for personal, business, and organizational purposes. Excel contains most of the features of all spreadsheet programs.

### Features and terminologies

Cell – A cell is a rectangular area formed by the intersection of a column and a row in a spreadsheet. A cell has a cell reference or name or cell address, which is the combination of the column header and row label, e.g. cell A1, G3, etc.

Active Cell – The active cell is the cell in the spreadsheet that is currently selected for data entry.

Cell Name – This is by default the cell reference or address. However, one may define a particular cell or range of cells with an alternative name. This alternative name can then be used in formulas and functions. It can also provide a quick way to jump to a particular area of the spreadsheet.

Cell Reference – This is the name of the cell that is found by combining the Column Letter with the Row Number. For example, the cell in Column “A” in Row “5” would be cell A5.

Column – This refers to the vertical bars on the
spreadsheet screen. In Excel 2013, it is labeled with alphabet A – XFD. Excel 2013 can
handle up to 2^{14} labels giving a total of 16384 columns.

Chart – This is a pictorial representation that is used to summarize categorized data. There are different types of charts used in the excel spreadsheet, ranging from the bar chart, line graph, pie chart, etc.

Data – This refers to the type of information that can be stored in the cells of a spreadsheet. Spreadsheet data types include values (numbers), labels, formulas, and functions.

Formula – This is a spreadsheet data type that will perform calculation and display the result in the active cell. A formula is written using cell references and must always begin with an equal sign “=” to distinguish it from a label. E.g. “=G5/H5”.

Formula Bar – It appears directly above the column headings of a spreadsheet and will display what has been typed into the active cell.

Function – Functions are built-in formulas in a spreadsheet. It can be simple or complex formulas. Like formulas, functions begin with an equal sign “=” and use cell references in their format. E.g. (=sum A1: A5) will calculate the total sum of values in cells A1 to A5.

Gridlines – These are the horizontal and vertical lines on the screen that separate cells in a spreadsheet. Gridlines do not print by default unless the option is set in the layout options of the spreadsheet.

Name Box – Also called the address bar. It appears to the left of the formula bar and displays the name of the current cell unless you define a cell or range of cells with a specific name.

Range – A range is a group of cells in a spreadsheet that has been selected. E.g. a selection from cells B1 through F5 will be represented as B1:F5 and is shown below:

Rows – Rows are horizontal bars on the
spreadsheet screen. Excel 2013 spreadsheet contains 2^{20} = 1048576 rows
which are labeled from 1 to 1048576.

Values – These are numeric data entered into a cell. Numbers are aligned to the right by default in an excel spreadsheet.

Workbook – Excel spreadsheet files are called a workbook. A workbook is a collection of worksheets that are saved together in one file.

Worksheet – A worksheet is the grid of columns and rows that information is inputted into. In Excel, one workbook can contain several worksheets. Worksheets can be named using the worksheet tabs at the bottom of the spreadsheet window.

The sheet tabs can also be used to switch from one worksheet to another within a workbook. Previous versions of Excel display 3 worksheets by default when it is loaded, but the 2013 and 2016 versions display only one worksheet. The user has the option of adding more worksheets as required.
