Actual Formula Copied Formulas Formula Copying • Formula copying results in formula reuse without retyping. • Requirements in Formula Copying 1. Cell addresses in the copied formula should be picked from the same relative positions as they were in the actual formula.
Absolute Position: C2 Copied Formulas ..Formula Copying • Requirements in Formula Copying 2. Cell addresses in the copied formula should be picked from an absolute position.
Relative Cell Name: B5 Absolute Cell Name: $C$2 Copied Formulas ..Formula Copying • Formula Requirement Implementation in Spreadsheet Programs Req#1: Use of Relative Cell Names (like B2, C2 etc.)– for changing cell locations. Req#2: Use of Absolute Cell Names (like $C$2 etc.)– for fixed cell locations.
Example: Relative Reference (C2) Formula Copying in Microsoft Excel • For formula having relative cell names : 1. If copy is made downward (in the same column), Cell’s Row# changes only (by row displacement). 2. If copy is made rightward (in the same row), the Cell’s column letterchanges only (by column displacement).
..Formula Copying in Microsoft Excel • For formula having cell names with $ symbols The cell dimension (column or row) having a $ symbol will not be affected by copying process. Examples $C$2 - Use for an Absolute Cell Reference Downward Copying: No change Rightward Copying: No change $C2 – Use for a Mixed Cell Reference Downward Copying: Row# changes Rightward Copying: No change C$2 – Use for a Mixed Cell Reference Downward Copying: No change Rightward Copying: Column letter changes
Formatting Spreadsheets • Formatting a sheet results in • Improved sheet outlooks. • More understandable sheets. • Categorized into two classes. • Formatting a sheet look/ appearance • Row height / Column widths • Foreground/ background colors (for emphasis) • Selecting Fonts • Borders • Text Control in Cells (Wrap text, angular text label etc.)
Number Formatting in Spreadsheets • ….Two Formatting Classes • Formatting sheet data values. • Currency values with currency symbols/ separator etc. • Desired number of decimals/ negative number representations. • Display decimal values as Fractions. • Display decimal values as percentages. Important: Changing the format, doesn’t change the actual value of a cell, but only the displayed value.
Number Formatting in Spreadsheets • To make a worksheet data (values/ formula results) more readable. • Add useful symbols and/ or separators in the display of a number. • Available Number Format Options in Microsoft Excel are as follows:
Date/Time Arithmetic in Spreadsheets • Date Arithmetic allows the user to do date/ time calculations • Spreadsheet software treats date/time as numeric values (behind the scenes) • Examples: • Number of days between two date values • What will be the date after 20 days from now?
Advanced Formatting Techniques in Excel • Auto Format • Allows the user to quickly format a spreadsheet table. • Every auto-format scheme includes a bunch of format techniques. • Users can collectively apply a selection of these formats by • Selecting a table area on a worksheet. • Apply an auto format scheme from the given list. • Select the formats to be included from that scheme. Microsoft Excel, Formats| AutoFormat…
….Advanced Formatting Techniques in Excel • Conditional Formatting • Content based formatting on spreadsheet cells. • Allows to monitor large data tables efficiently. • Needs user to enter criteria expressions for cell formattings. • Spreadsheet program applies the criteria on each cell dynamically and does the formatting accordingly.
Using Internet Features • Spreadsheet software allows user to • Create documents to be placed on Internet (HTML version) • Communicate with automated sites to receive relevant data (Use of Web Query in Excel) • Example: • In a spreadsheet using stock price details, the current data can be retrieved using a Web Query.
