Databases

Databases manages data. For example, once you enter data onto a worksheet, Excel can sort the data, search for specific data and select data that meets a criteria.

Web Support

Support allows Excel to save workbooks or parts of a workbook in HTML (Hyper Text Markup Language) format so that they can be viewed and manipulated using a browser

A new workbook opens with 3 worksheets. If necessary, with 3 worksheets. If necessary, you can add additional worksheets you can add additional worksheets to a maximum of to a maximum of 255 worksheet255 worksheetss

The Worksheet.

The worksheet is organized into a rectangular grid containing columns (vertical) and rows (horizontal).

A column letter above the A column letter above the

The intersection of each row and column is a cell.

A cell is the basic unit of the worksheet into which you enter data. Each worksheet in a workbook has 256 columns and 65,536 rows for a total of 16,777,216 cells.

Only a small fraction of the active worksheet displays on the screen at one time.

A cell is referred to by its unique address, or cell reference, which is the coordinate of the intersection of a row and a column. To identify a cell, specify the column letter first, followed by the row number.

One cell on the worksheet designated the active cell, is the one in which you can enter data. The active cell is identified in three ways.

First, a heavy black border surrounds the cell;

second, the active cell reference displays in the Name box;

and third, the column and row heading light up.

The horizontal and vertical lines on the worksheet itself are called gridlines.

Worksheet Window

You view the portion of the worksheet displayed on the screen through a worksheet window. Below and to the right of the worksheet window are, scroll bars, scroll arrows, and scroll boxes that you can use to move the window around to view different parts of the active worksheet.

The Excel Worksheet.

The workbook is like a notebook. It has sheets called worksheet.

Sheet tabs are used to display sheet names

A workbook opens with 3 sheets, if desired 252 more can be added.

There are 256 columns in a spreadsheet. Each column is represented by a LETTER (A – IV)

There are 65,536 rows in a spreadsheet. Each row is represented by a NUMBER. (1 – 65,536)

A CELL is formed where a row and a column intersects (cross).

There are 16,777,216 cells in a worksheet. Each cell is identified by its unique CELL ADDRESS or CELL REFERENCE. (A1 – IV65,536)

The Active cell can be identified as followings:

1. Heavy black border surrounds the cell

2. The cell name is displayed in the name box

3. The row and column heading light up

Name box – identifies the worksheet for the computer

Part 2: Understanding Formulas

In excel, formulas are used to perform all kinds of calculations on your Excel data. You can build formulas using mathematical operators, values, and cell references.

Formula Structure In Excel, formula structure works a bit

different from the ordinary mathematical formula. All Excel formulas begin with an equal sign (=), such as = 2+2. The equal sign immediately tells Excel to recognize any subsequent data as a formula rather than as a regular cell entry.

Cont’d Referencing Cells

Although you can enter specific values in your Excel formulas, you can also easily reference data in specific cells. For e.g., you can add 2 cells together or multiply the contents of one cell by a value.

Every cell in a worksheet has a unique address, also called a CELL REFERENCE.

By default, cells are identified by their specific column letter and then by their row number, i.e. cell D5 identifies the fifth cell down in column D.

Cont’d. Cell Ranges A group of related cells in a worksheet is

called a range. Excel identifies a cell range by the anchor points in the upper-left and lower-right corners of the range.

The range reference includes both anchor points separated by a colon. E.g., the range name A1:B3 includes cells A1, A2, A3, B1, B2, B3. Can also assign unique names to your ranges to make it easier to identify their contents. Spaces are NOT allowed in range names
