How can one use efficiently MicrosoftExcel? Excel is without doubt a very powerful spreadsheet application and arguably the best in the world. However, many people often design their spreadsheets with no foresight at all. This means most spreadsheets have poor foundations and have limited life spans. Perhaps the number one rule when designing a spreadsheet is, we should start with the end in mind and never assume you will not need to add more data or formulae to your spreadsheet, because, the chances are that you will. A good spreadsheet should have about 80% planning and 20% implementation. While this can seem extremely inefficient in the short run, I can assure you that the long term gain will far outweigh the short-term pain. Remember that spreadsheets are about giving correct information to the user, not possible erroneous information that looks good. Let’s look at how a spreadsheet should be set up efficiently. The very 1st thing you SHOULD know about Excel is that ALL versions contain far more rows than the Application can ever hope to handle. Why Microsoft continue to mislead its users by supplying far more rows than it can handle remains a mystery. My best guess is that, like most car speedometers, the upper range exceeds the cars capabilities. Even with newer versions, the expectations far exceed the Applications capabilities. In fact, the problems (misleading of its users) gets worse. For Example, Excel 2007 now has 1 million rows and if you fill just 1 column using all rows, save a close, you will very likely never be able to open the Workbook again. BUYER BEWARE AND DON’T FORGET ABOUT MS ACCESS! While a spreadsheet should be easy to read and follow, this should rarely be at the expense of efficiency. I myself am a big believer in ‘keep it simple stupid‘ (K.I.S.S). Far too many people spend about 30%, or more, of their time formatting their spreadsheets. This time (although they don’t realize it) often comes at the expense of efficiency and accuracy. Often the overuse of formatting adds size to your Workbook and while it may look like a work of art to you, it may look terrible to another. Some very good universal colors are black, white and grey. Only ever use the cell format of Text if really necessary. This is because all data entered into the cell becomes text and spreadsheets are all about numbers. Worse still, is any cell housing a formula, that is referencing a Text formatted cell, will also become formatted as Text. Believe me, you do not want formula cells to be formatted as Text! This format is VERY rarely needed, yet frequently used. If you apply a number format to specific cells try to not apply the format to the entire column. If you do, Excel will assume you are using these cells. This can give unexpected results when locating the last used cell. With 65536 (1 Million in 2007) rows in Excel it wont take too long before you had told Excel that you are using millions of cells, when in reality the number is only in the thousands! Having said not to format entire columns & rows, it should be noted that intermittent & sporadic formatting to individual cells can increase file size. If you want your formatting to automatically apply to new data, either use the “Format Painter” (paint brush icon on the formatting toolbar). Or go to Tools>Options | Edit and check “Extend list formats and formulas” (checked by default) this will format new items added to the end of a list to match the format of the rest of the list. Formulas that are repeated in every row are also copied. To be extended, formats and formulas must appear in at least three of the five last rows preceding the new row. Microsoft’s Tips For Optimizing Speed In Microsoft Excel, recalculation performance is affected by the way data and formulas are arranged on the worksheet. The following list contains tips for optimizing your worksheet to improve recalculation speed: Organize your worksheets vertically. Use only one or two screens of columns, but as many rows as possible. A strict vertical scheme promotes a clearer flow of calculation. When possible, a formula should refer only to the cells above it. As a result, your calculations should proceed strictly downward, from raw data at the top to final calculations at the bottom. If your formulas require a large amount of raw data, you might want to move the data to a separate worksheet and link the data to the sheet containing the formulas. Formulas should be as simple as possible to prevent any unnecessary calculations. If you use constants in a formula, calculate the constants before entering them into the formula, rather than having Microsoft Excel calculate them during each recalculation cycle. Reduce, or eliminate, the use of data tables in your spreadsheet or set data table calculation to manual. If you only need a few cells to be recalculated, replace the equal signs (=) of the cells you want to be recalculated. This is only an improvement if you are calculating a very small percentage of the formulas on your worksheet. When a certain group of formulas must be recalculated a great number of times, then it may be helpful to replace the equal sign (=) in the formulas that you do not need to recalculate with a unique string that does not appear elsewhere. The formulas without the equal signs will not be recalculated (they are no longer considered formulas). When Microsoft Excel has recalculated the formulas that still contain equal signs, search for the unique string and restore the =. Microsoft Knowledge Base Article – Q72622 Recalculation in Microsoft Excel Improving Performance in Excel 2007 How do you get started in Excel? This handout introduces the basic features of Microsoft Excel, a spreadsheet program on Macintoshes and on computers running Microsoft Windows. The handout covers entering and editing data, formatting, formulas, page setup, and printing spreadsheets. Starting Excel You can start Excel by:1. Double-clicking on the Microsoft Excel application icon. This application is usually in a folder called Excel. An alias for this icon appears on the desktop of the computers in the Student Microcomputer Facility. 2. Double-clicking on the icon of any Excel document. When you double-click an Excel document, Excel opens with the document already loaded. Exploring the Excel Interface Components of the Excel Window Besides the usual window components (close box, title bar, scroll bars, etc.), an Excel window has several unique elements identified in the figure below. Standard Toolbar The Standard toolbar, located beneath the menu bar, has buttons for commonly performed tasks like adding a column of numbers, printing, sorting, and other operations. Excel let’s you customize the toolbar or even display multiple toolbars at the same time. The Standard Excel XP toolbar appears in the figure below. Formatting toolbar The Formatting toolbar, located beneath the Standard toolbar bar, has buttons for various formatting operations like changing text size or style, formatting numbers and placing borders around cells. Formula bar The formula bar is located beneath the toolbar at the top of the Excel worksheet. Use the formula bar to enter and edit worksheet data. The contents of the active cell always appear in the formula bar. When you click the mouse in the formula bar, an X and a check mark appear. You can click the check icon to confirm and completes editing, or the X to abandon editing. Name box The Name box displays the reference of the selected cells. Row and column headings Letters and numbers identify the rows and columns on an Excel spreadsheet. The intersection of a row and a column is called a cell. Use row and column headings to specify a cell’s reference. For example, the cell located where column B and row 7 intersect is called B7. Active cell The active cell has a dark border around it to indicate your position in the worksheet. All text and numbers that you type are inserted into the active cell. Click the mouse on a cell to make it active. Fill handle The lower right corner of the active cell has a small box called a Fill Handle. Your mouse changes to a cross-hair when you are on the Fill Handle. The Fill Handle helps you copy data and create series of information. For example, if you type January in the active cell and then drag the Fill Handle over four cells, Excel automatically inserts February, March, April and May. Worksheet tabs An Excel workbook consists of multiple worksheets. Use the worksheet tabs at the bottom of the screen to navigate between worksheets within a workbook. Working with Excel documents Opening and Closing Documents To open an existing Excel workbook, choose Open from the File menu or click the Open tool on the toolbar. Excel will display the Open dialog box, which is similar in appearance and function to the Save As dialog box. It contains a File Name: box for you to type a file name or file specification, a Look In: box to designate a location, and a drop-down menu of file types.
