Use pointing to enter a formula


3

Objectives (2 of 2)

Insert a hyperlink into an Excel worksheet

Save a worksheet as a Web page Learn the concept of “round trip

html” Import data from a web query into

an Excel workbook Describe the Today function and

date arithmetic


4

Overview

Review relative, absolute, and mixed references

Isolate your assumptions Learn to use the mouse to enter and

copy formulas quickly Integrate Excel and the World Wide

Web Learn the Today function Learn the use of date arithmetic


5

Cell Referencing

Absolute reference: remains constant throughout a copy operation Specified with a dollar sign before the column and

row, i.e. $B$4 Relative reference: adjusts during a copy

operation Specified without dollar signs, i.e. B4

The F4 key is a quick way to cycle through absolute, relative, and mixed cell references


6

Getting the most from Excel

Point to cell address for formulas or functions Use the mouse to select the cells you

want to include More accurate

Using the fill handle to copy Use the mouse to select the cell(s) you

want to copy and drag to copy to a destination range


7

Hands-on Exercise 1

Objective: Develop a spreadsheet using relative and absolute cell references Compute the gross pay Complete the remaining calculations Copy the formulas Compute the totals Format the spreadsheet Complete the formatting The completed workbook


8

Isolate Assumptions

Base your formulas on cell references, rather than values

The cells containing the values (assumptions) should be clearly labeled and set apart

Change the assumptions in the worksheet and see the effects instantly Also minimizes the chance for error: you

change the assumptions in one place


9

Excel and the Internet

Three basic Internet capabilities: Insert a hyperlink into a worksheet Save a workbook as a Web page Download information from the Web

through a Web query


10

Some Internet Terms

HTML (HyperText Markup Language): a universal standard that can be recognized by all major web browsers A “web page” is a common name for an HTML

document Round trip HTML: allows you to edit a web

13

Web Queries

A web query allows Excel to go to a specific site on the Web to retrieve information Assumes you have an Internet

connection Created using the Import External

Data command Query can be updated anytime by

using the Refresh command


14

Web Queries


15

Date Arithmetic

Excel stores all dates as integers Serial numbers, beginning with January

1, 1900 The difference between dates is

determined by subtracting one number from another

Today() function always returns the current date


16

Hands-on Exercise 3

Objective: To include a Web query into a worksheet; to use the Today() function Open the existing workbook Complete the Web query Compute the gain/loss Copy the formulas Format the worksheet Refresh the query


17

Summary (1 of 2)

Absolute, mixed, and relative references

Isolate your assumptions from the rest of the worksheet

Enter cell references into formulas by pointing to them with the mouse

Use the fill handle to copy a formula to adjacent cells


18

Summary (2 of 2)

Insert hyperlinks into Excel worksheets

Save workbooks or worksheets as Web pages (HTML documents)

Use Web queries to retrieve information from the Web

Dates stored as serial integers Today() function always returns the

current date
