I did [depreciation, calculations] with spreadsheets before, but, because of tax laws changing so much, you have, to keep track of ACE (adjusted current earnings),, AMT (alternative minimum tax) and four or five, other methods of reporting. And updating would, take four or five hours. Now, with one button,, the information just rolls over.”, Terry Rogers, Consultant, Datacentrik Solutions, Vancouver., , Introduction, In our daily life, we may have come across a list of, items in tabular form several times. For example,, the shopping bills, the school annual report card,, or the cricket match scorecard. These tables with, rows and columns are called spreadsheets. If we, have to tabulate and analyse the data for the, Indian team’s performance in a cricket series and, submit a project as part of our course evaluation,, we will perhaps take a chart paper and design the, project, write a report and submit it. That’s the, way we have done it all along. The project may, completely cover all aspects of the series but we, are not happy with it. This is because the project, report is static – we cannot make dynamic analysis, using this paper report. How do we then get, attention of our audience? Welcome to the world, of electronic spreadsheets, where we can do all, these, and much more. Let us see how.

Electronic Spreadsheet, , 4.1 A SPREADSHEET, A spreadsheet is defined as a large sheet which contains data and, information arranged in rows and columns. There are different spreadsheet, programs available; some are proprietary, like Microsoft Excel, Lotus 123,, etc., others are free/open source like, Gnome Office Spreadsheet Gnumeric,, KOffice KSpread, OpenOffic.org Calc. Spreadsheets, also known as, worksheets, allow us to perform detailed analysis on numerical data., Data is entered in a cell, which represents the intersection of a row and a, column. The most powerful feature of a spreadsheet is that it automatically, recalculates the result of mathematical formulas if the source data changes., A spreadsheet can help us quickly record and manipulate a large amount, of numerical information and share it with others in a wide variety of, forms. Since MS-Excel, an integral, Standard Toolbar, Title bar, Formatting, component of MS-Office, is one of the, programs which has all these features, and many more we have taken it as a, spreadsheet program., Active Cell, , 4.2 STARTING A, SPREADSHEET, PROGRAM, To start follow the steps given below:, 1. Click on, button on the, Taskbar., option in, 2. Click on, the pop-up window., 3. Click on, , Active, , Figure 4.1 : A blank spreadsheet, , A blank spreadsheet as shown in figure 4.1 is displayed., , 4.3 BASIC SPREASDSHEET ELEMENTS, 4.3.1 WORKBOOK AND WORKSHEET, Each speadsheet file is known as a workbook and is stored with a default, extension of .xls. Each workbook can contain many sheets, so various, kinds of related information can be organised in a single file. Each, workbook can contain up to 255 worksheets, but by default it displays, only three. Worksheet is the area where the data is stored and work is, performed. Extra worksheets can be added as and when required., , 4.3.2 ROWS, COLUMNS, , AND, , CELLS, , The rows in a worksheet are numbered from top to bottom along the, left column of the worksheet. The columns are labeled from left to, right with letters. The total number of rows in Excel are 65536 and the, , 97

Page 3 :
Computers and Communication Technology, , total number of columns are 256. Columns are named from A to IV., The rows are numbered from 1 to 65536., A cell is the intersection of a row and a column. A cell is identified, by an address that consists of the column name followed by the row, number. For example, the first cell is referred to as A1, which indicates, that it lies at the intersection of the column A and row 1. This is the, active cell. The active cell is ready for accepting any action or input. A, small group of contiguous cells is defined as a range. The range is, referred to by writing the starting address of the cell in the range:, Ending address of the cell in a range or vice versa. For example A1:A10, (can also be referred as A10 : A1)., , 4.4 NAVIGATING IN A WORKSHEET, The cursor keys, mouse and the scroll bar can be used to navigate, through the worksheet. However, navigating through the 65,536 rows, and 256 columns using these techniques is very inefficient. To move to, any cell directly without scrolling through the entire worksheet, use, any of the following shortcut methods:, Method 1 : Using key combinations, Movement, , Key Stroke, , One cell up, , Up arrow key (“, “), , One cell down, , Down arrow key or ENTER (”, ”), , One cell left, , Left arrow key (‘, ‘), , One cell right, , Right arrow key or TAB (’, ’), , Top of the worksheet, (cell A1), , CTRL + HOME, , End of the worksheet, (last cell containing data), , CTRL + END, , End of the row, , CTRL + right arrow key or END +, right arrow key, , End of the column, , CTRL + down arrow key or END +, down arrow key, , Method 2 : Using the name box, 1. Type the cell address in the Name Box, 2. Press ENTER to reach the desired cell., For example, to move to cell D6, enter D6 in the Name Box and press, ENTER. The cursor is positioned on the cell in the D column and 6th row., , 9988, , Method 3 : Using the go to dialog box, 1. Press F5 or CTRL + G or choose Go To option from the Edit menu to

Page 4 :
Electronic Spreadsheet, , invoke the Go To dialog box., 2. Enter the cell coordinates in the Reference textbox., 3. Click OK to move to the desired cell., , 4.4.1 NAVIGATING BETWEEN WORKSHEETS, To move between worksheets,, simply click on the sheet number, in the lower left corner of the, screen (Figure 4.2). In case the, number of worksheets is more than, the number which can be displayed, use the tab scrolling buttons,, located next to the sheet numbers, and then click on the sheet, number to select it., The tab scrolling buttons and, their use are given below:, , Click on the Sheet, number to open the sheet, , Tab scrolling, buttons, , Figure 4.2 : Spreadsheet showing different worksheets, , Icon, , Movement, , t|, , To display the first worksheet, , u|, , To display the last worksheet, , t, , To display adjacent worksheets on the left, , u, , To display adjacent worksheets on the right, , 4.5 SAVING A WORKBOOK, To save a Workbook:, 1. Choose the Save As option from the File menu or Click on the Save, button on the Standard Toolbar or Close the workbook by clicking, on the Close button. The Save As dialog box is displayed as shown, in the figure., 2. Select the directory in which the file is to be saved., 3. Type the name of the file in the File Name text box., 4. Click Save., , 4.6 OPENING A WORKBOOK, To open a workbook:, 1. Choose Open option from the File menu or Click on the Open button, on the Standard Toolbar., 2. Select directory in which the file has been saved., 3. Type the name of the file in the File Name field or select the name, by clicking on it., 4. Click Open., , 99

Computers and Communication Technology, , 4.7 USING FORMULAS AND FUNCTIONS, Formulas are entries containing an equation that calculates the value, to be displayed. Please remember, when working with formulas, do not, type in the numbers but type in the equation. This equation will be, automatically updated upon the change or entry of any data that is, referenced in the equation., , 4.7.1 ENTERING FORMULAS, Cells in a worksheet can also contain formulas that are helpful in, performing calculations. Formulas are mathematical equations. They, are useful for establishing the relationship between two or more cells., They contain the coordinates of the, Value displayed in the cell, cells that are used in the formula,, operators and functions. When a, formula is entered, the cell, displays the result of the formula., Formulas must begin with an =, sign, otherwise it is treated as a, text entry (Figure 4.3)., , Figure 4.3 : Using formula in a Spreadsheet, , Whenever any cell value is, changed it automatically, recalculates the values of any, formula and displays it in the, relevant cell., , Using Arithmetic Operators, When a number is entered into a cell, it is possible to perform, mathematical calculations using them. Spreadsheets have many, mathematical functions built into, them. The most basic operations, used widely are addition,, subtraction, multiplication and, division. Follow the given steps to, perform addition., 1. Move the cursor to cell A1., Type 1., 2. Press Enter to move to cell A2., Type 1 in cell A2., 3. Press Enter to move to cell A3., 4. Type =A1+A2 in cell A3., Place the cursor in cell A3, and look at the Formula bar., , 110000, , Figure 4.4 : Working with Math Function, , Note that the contents of cell, A1 and A2 have been added and, the result is shown in cell A3, (Figure 4.4).

Page 6 :
Electronic Spreadsheet, , The same steps can be followed to perform other mathematical, operations by simply changing the formula typed into cell A3., Using Auto Sum, The addition of numbers is one of the most frequently used actions., Thus, a toolbar button, AutoSum, has been provided to accomplish, this task. The AutoSum button on the Standard toolbar automatically, adds the values above the destination cell or to the left of the destination, cell. The steps to illustrate this are as follows:, 1. Click on the destination cell i.e. the cell in which the result is to be, displayed., 2. Click on the AutoSum button, which is located on the Standard, toolbar. The cells containing the numbers to be added automatically, should now be highlighted., 3. Press Enter to see the result in the destination cell., , 4.7.2 FUNCTIONS, This has a set of prewritten formulas called functions. Functions are, special programs that accept data and return a value after processing, the data. Functions differ from regular formulas because they accept, values and not the operators, such as +, -, *, or /. For example, the, SUM function can be used to add numbers in place of the ‘+’ operator., When using a function, remember the following :, •, •, •, •, , Use an equal to sign (=) to begin a formula., Specify the function name., Enclose arguments (data accepted by a function) within parentheses., Use a comma to separate arguments., , Some commonly used Functions are listed in Table representing, some commonly used Functions (Appendix 4.1), , 4.7.3 COPYING, , AND, , PASTING FORMULAS, , AND, , FUNCTIONS, , Sometimes when working with formulas, the need arises to repeat the, same formula for many different cells. The formulas can be copied, using various methods., Method 1 : Using the Edit menu, Steps are given below:, 1., 2., 3., 4., , Click on the cell that contains the formula., Choose the Copy option from the Edit menu., Click on the cell where the formula is to be copied., Choose the Paste option from the Edit menu. Note the change in, the cell reference., 5. Press Esc to exit the Copy mode., , 101

Page 7 :
Computers and Communication Technology, , Method 2 : Using the Formatting Toolbar / Keyboard Shortcuts, Steps are given below :, 1. Click on the cell that contains the formula., 2. Click on the Copy icon, press Ctrl + C keys., , located on the Formatting toolbar or, , 3. Click on the cell where the formula is to be copied., 4. Click on the Paste icon, press Ctrl + V keys., , located on the Formatting toolbar or, , 5. Press Esc to exit the Copy mode., If a formula needs to be copied to multiple cells, use the AutoFill, feature discussed later in the lesson., , 4.7.4 CELL REFERENCING, Observe that when you copy and paste formulas, they are pasted relative, to the position they are copied from. This is because of the way the, formula treats the cell references. The cell coordinates in the formula, are known as cell references. Two commonly used cell references are –, Absolute and Relative., Absolute Referencing, Absolute referencing implies that the coordinates of a cell are not, changed when a formula is copied from one cell to another. To make a, cell address an absolute cell address place a dollar sign in front of, both the row and column identifiers. For example, $A$1 implies that, both row and column have been fixed or made absolute. In simple, words this means that while copying this formula to another cell,, neither the column name nor the row number will change., Relative Referencing, With relative cell referencing, when we copy a formula from one area, of the worksheet to another, it records the position of the cell relative, to the cell that originally contained the formula. This is the default, mode of referencing in a spreadsheet., The F4 key is used to toggle between the absolute and relative, modes of referencing cells., , 4.8 WORKING WITH WORKSHEET RANGES, 110022, , Each cell is referred to by a cell address. A group of cells are referenced, using a reference operator. There are two types of reference operators,, range and union.

Page 8 :
Electronic Spreadsheet, , • A range reference refers to all, the cells between and including, the reference (Figure 4.5). A, range reference consists of two, cell addresses separated by a, colon. The range reference, B1:B4 includes cells B1, B2, B3, and B4. The range reference, A1:B3 includes A1, A2, A3, B1,, B2 and B3., • A union reference includes two, Figure 4.5 : Worksheet Range, or more references. A union, reference consists of two or, more cell addresses separated by a comma. For example, the, reference A1, B5, C7 refers to cells A1, B5, and C7. Similarly, the, reference A1:A3,B4:B6 refers to cells A1, A2, A3, B4, B5 and B6., , 4.8.1 USING RANGE NAMES, , IN, , FORMULAS, , When working with large volumes of data in a worksheet, it is frequently, desirable to refer to a range of cells repeatedly. For example, if a column, in the worksheet contains the price of products, it will be required, again and again for calculating the total price of all products or, calculating the average price and so on. In such a case, it is convenient, and efficient to name this range meaningfully and use the name of the, range instead of the cell coordinates. Naming a range of cells has the, following advantages:, • Names are easier to remember than cell coordinates., • Names make navigation in a worksheet easier., • Named ranges can be used throughout a workbook easily. This is, very helpful while linking, worksheets in a workbook., , 4.8.2 CREATING RANGE, NAMES, Steps to create a named range are:, 1. Select the cell or range of cells, to be named., 2. Choose the Name option from, the Insert menu., 3. Choose the Define option from, the Name sub-menu. The Define, Name dialog box is displayed as, in figure 4.6., 4. Type in the name of the range in, the Names in a workbook text box., , Type the name, of the Range, , The Range, reference, , Figure 4.6 : To create Range Name from Name Option, of the Insert Menu, , 103

Page 9 :
Computers and Communication Technology, , 5. Click on the Add button to create the name. The name is, immediately added to the existing names in the box., 6. Click on the OK button to close the dialog box., , 4.8.3 USING RANGE NAMES, Simply type the name in the formula in place of the cell coordinates., For example, to find the maximum of a range of marks named Maths,, the formula will be =MAX(Maths)., , 4.9 WORKING WITH ROWS AND COLUMNS, To add extra information to a, worksheet, it may sometimes be, desirable to insert new rows and, columns. To insert a new row/, column, execute the following steps:, , 4.9.1 INSERTING, , Figure 4.7 : Inserting a row, , A, , ROW, , 1. Click on the Row Number (or any, cell in that row) above which, the new row is to be added., 2. Choose the Rows option from, the Insert menu. A row is, inserted above the selected row, (Figure 4.7)., 3. Click any where in the, spreadsheet to remove the, selection., , 4.9.2 INSERTING, , A, , COLUMN, , 1. Click on the Column name (or, any cell in that column)., 2. Choose the Columns option from, the Insert menu. A column is, inserted to the left of the, selected column (Figure 4.8)., 3. Click, anywhere, in, the, spreadsheet to remove the, selection., Blank, , 4.9.3 DELETING ROWS, COLUMNS, , Figure 4.8 : Inserting a column, , 110044, , AND, , When the contents of an entire row, , or column are to be deleted, perform the following steps:, 1. Click on the Row Number/Column Name to be deleted.

Click anywhere in the spreadsheet to remove the selection., , 4.9.4 INSERTING, , AND, , DELETING CELLS, , We can insert or delete individual cells also, rather than the entire, row or column., , Inserting a Cell, 1. Click on the cell where new cell(s) is to be inserted., 2. Choose the Cells option from the Insert menu., The Insert dialog box is displayed (Figure 4.9)., 3. Choose the appropriate option. The result of, each option is explained as under:, (a) Shift cells right – adds a blank cell to the, left of the selected cell., (b) Shift cells down – adds a blank cell above, the selected cell., (c) Entire row – adds a new row above the, selected cell., (d) Entire column – adds a new column to the, left of the selected cell., , Figure 4.9 : Insert dialog box, , 4. Click on OK button., , Deleting a Cell, 1. Click on the cell which is to be deleted., 2. Choose the Delete option from the Edit menu., The Delete dialog box is displayed as shown, in figure 4.10., 3. Choose the appropriate option. The result of, each option is explained as under:, (a) Shift cells left – the cells to the right of, the deleted cell are moved left., (b) Shift cells up – the cells below the deleted, cell are moved up., (c) Entire row – deletes the entire row and, moves the row below upwards., (d) Entire column – deletes the entire column, and moves the row to the right leftwards., , Fiugre 4.10 : Delete dialog box, , 4. Click on OK button., Note: If there is any data at the extreme right or at the end of the worksheet, it, does not allow us to insert cells or rows. This is because, it does not delete, existing contents from the worksheet while inserting cells. For example, if there, is data in row number 16,384, then inserting a row will result in an error., , 105
