Excel: Basics Excel Objects, User Interface, and Data Entry
The Excel User Interface • Common Features • Application Window • Title Bar • Menu Bar • Toolbars • Status Bar • Worksheet Window • Worksheet Input Area • Row and Column Headings • Sheet Tabs • Scroll Bars
Excel Objects • Excel Application • The Software Application • Workbook • Stored in an Excel data file • Filename has .xlsxextension • Worksheet • Workbook contains 3 by default • Sheet Tabs • Cell • Intersection of a row and a column • Cell Address or Cell Reference (A1, BA542, etc.) • Range • A range is a grouping of two or more cells • Vertical / horizontal grouping of all cells in the dimension • Names are Alpha / Numeric
Excel Data Entry • Data are inputs to Cells • Excel interprets each cell entry as: • Value – numeric constant • Text – any other combination of numeric/nonnumeric chars. • Formula • Each Cell has a Returned Value
Excel Data Entry • Value and Text Entry - the returned value is identical to the entry data • Text • Data Labels like January, February, ... • Value • Numbers that can be used in calculations like 54, 78 • Times or Dates like 2/9/2000
Excel Data Entry - Formula • Formula Entry - the returned value is the result of a computation that may include: • operators • Some formula (arithmetic) operators: * / + - • cell references • Including named cells and/or ranges • A1, B43, A1:D7 • literal values or strings • 46.9, 2.0, 879, January, Monday • worksheet functions and arguments • parentheses • that control the order in which expressions in the formula are evaluated
Excel Data - Formula Entry • Starts with = sign • Examples (assume value A1 is 4, B2 is 3): • Entry: =7+9 Returned Value: 16 • Entry: =A2*5 Returned Value: 20 • Entry: =(A1-B2)*6 Returned Value: 6 • Entry: =“Sat” Returned Value: Sat
Excel Data - Formula Entry • Worksheet Functions a predefined computational task or calculation • Every Function Consists of: • Function Name • Arguments • literal values, cell references, expressions, functions • arguments are separated by commas • argument list is enclosed in parentheses • Example: = SUM(4,6,10,B8)
A Few Functions • Functions: • SUM • AVERAGE • MAX • MIN • COUNT • COUNTIF • SUMIF • ROUND
Why Use Spreadsheet Apps? • Value, Text and Formula Entries can be easily duplicated to other cells • When you copy a cell you are copying both entry and formatting • Formatting refers: • Numeric Formatting • Stylistic Formatting • Copy using: • Home | Copy Home | Paste • Drag n Drop using edge of selection
Copying Considerations • Cell and Range References • Relative • Cell reference adjusts to new location • Absolute • Cell reference does not change • Mixed References • Row Absolute • Column part adjusts, row part does not change • Column Absolute • Row part adjusts, column part does not change
Excel continues • Math operations with multiple spreadsheets • Protection by a password • Conditional formatting • Function If • Function AND • Using IF and AND in a formula • Data tools
Importing Data • Guidelines for importing foreign data: • When possible, save data as tab-delimited ASCII text in a file with a .txt extension; • When data comes from the Web, select a browser that supports Copy/Paste of tagged tables; • When the foreign data format is messed up, use a text editor with Search/Replace, apply placeholder technique, and write the revised data with .txt extension.
