What is Excel Used For?

    A Brief MS Excel Tutorial

Microsoft Excel provides a grid interface to organize nearly any type of information.  The power of Excel lies in it's flexibility to define the layout and structure of the information you want to manage.  Basic tasks require no special training, and Excel allows you to work with text, numbers, and date information in a relatively open and unstructured way.  Nearly 30 years after it's initial introduction, Excel remains the worlds leading spreadsheet software.

This brief article provides an introduction to Microsoft Excel, major uses, and key features every Excel user should be aware of.

Major Uses for Excel

Excel is used widely in any financially-related activity.  The ability to create new spreadsheets where users can define custom formulas to calculate anything from a simple quarterly forecast to a full corporate annual report makes Excel highly appealing.  Excel is also used widely for common information organization and tracking like a list of sales leads, project status reports, contact lists, and invoicing.  Finally, Excel is a useful tool for scientific and statistical analysis with large data sets.  Excel's statistical formulas and graphing can help researches perform variance analysis, chi-square testing, and chart complex data.

How Excel Works

An Excel document is called a Workbook.  A workbook always has at least one Worksheet.  Workseets are the grid where you can store and calculate data.  You can have many worksheets stored inside a workbook, each with a unique worksheet name.

Worksheets are laid out in columns (vertical) and rows (horizontal).  The intersection of any given row and column is a cell.  Cells are really where you enter any information.  A cell will accept a large amount of text, or you can enter a date, number, or formula.  Each cell can be formatted individually with distinct border, background color, and font color/size/type. 

Excel Formulas

You can create simple and complex formulas in Excel to calculate just about anything.  Inputs to a formula may be other cells, the results of other formulas, or just straight-forward math (5*2+3).  Excel includes a formula library for calculating things like Net Present Value (NPV), standard deviation, interest payments over time, and other common financial and mathematic formulae. Excel's formula bar includes a feature to help you search for a formula you need, and also helps you select the appropriate cells in your workbook to calculate the formula.

Excel Charting

Excel offers a wide array of charts to visualize data.  They range from simple line graphs to bubble and radar charts.  Excel has two main tools for charting:  standard charts and pivot charts.

Excel worksheet

A standard chart is relatively static one you create it.  As you change data in your spreadsheet, related cells will refresh the chart to show the new updates.  A pivot chart is more dynamic, allowing you to "slice-and-dice" your data in several different ways by choosing which columns contain the information you want to group by, or apply mathematical operations (sum, count, average, find the maximum, etc).

Excel vs Word Tables

A common question is when to use the table layouts in Word, and when to use Excel to present a list.  Both have important features appropriate for specific uses.  Even if you have a Word document where you want to display tabular information, the easiest path may be to embedd an Excel sheet within the Word document.  In general, Excel shines with sorting, conditional formatting, and when the table should be dynamically calculated (to save from copy/pasting into Word as totals change).  On the other hand, if your table is mostly just textual information, Word is an excellent tool to display the tabular information.

Need Best Application
Primarily textual information Word table
Text and numeric/date information Word table or Excel
Numeric information based on dynamic calculations Excel
Conditional formatting of date fields compared to current date Excel
Sorting by text, date, or numeric values Excel
