OBJECTIVES

• Cell reference• Basic functions• Logical, lookup and financial functions• PMT function• Range Names• Import text data• Import xml data

3

CELL REFERENCE

• 3 types :– Relative reference– Absolute reference– Mixed reference

4

RELATIVE CELL REFERENCE

• Indicates a cell’s relative location from the cell containing the formula– such as two rows up and one column to the

left

• The cell reference changes when the formula is copied– maintain the same relative distance from the

copied formula cell– Example, =A8-B8

5

RELATIVE CELL REFERENCERelative cell reference

6

RELATIVE CELL REFERENCERelative cell reference

Selected cell

7

RELATIVE CELL REFERENCE

• Why this happen ?– Because you copy the formula down the

column to cell C12– the column letters in the formula stay the

same, but the row numbers change, down one row number at a time.

8

ABSOLUTE CELL REFERENCE

• Indicates a cell’s specific location– provides a permanent reference to a specific

cell

• the cell reference does not change when you copy the formula– Regardless of where you copy the formula– Appears with a dollar sign before both the

column letter and row number, such as $B$5.

9

ABSOLUTE CELL REFERENCE

Absolute cell reference

Selected cell

10

ABSOLUTE CELL REFERENCE

Formulas referringto this cell should contain an absolute reference

11

ABSOLUTE CELL REFERENCE

• For B8 = A8*$B$5– A8 is relative reference, changes as you copy

the formula to C9– *$B$5 is absolute reference, does not change

to B6

12

MIXED CELL REFERENCE

• Contains both an absolute and a relative cell reference in a formula– combines an absolute cell reference with a

relative cell reference

• The absolute part does not change but the relative part does when you copy the formula.– either the column letter or the row number

13

MIXED CELL REFERENCE

• Example – – $B5 or B$5 is a mixed cell reference– $B5, the column B is absolute, and the row

number is relative; when you copy the formula, the column letter, B, does not change, but the row number will change.

– B$5, the column letter, B, changes, but the row number, 5, does not change.

14

MIXED CELL REFERENCEMixed cell reference

Selected cell

15

MIXED CELL REFERENCE

• Because you are copying down the same column, only the row reference 5 must be absolute; the column letter stays the same

16

SHORTCUT KEYS

• The F4 key toggles through relative, absolute, and mixed references. Click a cell reference within a formula on the Formula Bar, and then press F4 to change it. – For example, click in B5 in the formula =A8*B5. Press F4,

and the relative cell reference (B5) changes to an absolute cell reference ($B$5).

– Press F4 again, and $B$5 becomes a mixed reference (B$5); – press F4 again, and it becomes another mixed reference

($B5). – Press F4 a fourth time, and the cell reference returns to the

original relative reference (B5).

• Function ScreenTip, a small pop-up description that displays the function’s arguments

LOGICAL FUNCTION

• The IF function evaluates a condition and returns one value if the condition is true and a different value if the condition is false.=IF(logical_test,value_if_true,value_if_false)

• The logical test is an expression that evaluates to true or false.– result is either true or false

PMT FUNCTION

33

PMT FUNCTION

• The PMT function calculates the periodic payment for a loan with a fixed interest rate and fixed term.

• =PMT(rate,nper,pv,[fv],[type])

34

PMT FUNCTION

• =PMT(rate,nper,pv,[fv],[type])• The rate is the periodic interest rate, such

as a monthly interest rate.• The nper is the number of total payment

periods.• The pv is the present value of the loan.

35

RANGE NAMES

• Range names make it easier to specify ranges in formulas and find ranges within large spreadsheets– Must begin with a letter or underscore– Only letters, numbers, underscores, and

periods

• You can reference the range in formulas with the name instead of using absolute references

36

RANGE NAMES

• Grades - Acceptable range name• COL - Acceptable abbreviation for cost-of-living• Tax_Rate - Acceptable name with underscore• Commission Rate - Unacceptable name; can’t use

spaces in names• Discount Rate % - Unacceptable name; can’t use

special symbols and spaces• 2009_Rate - Unacceptable name; can’t start with a

number• Rate_2012 - Acceptable name with underscore and

numbers

37

MANAGING RANGE NAMES

• Name Box• Name Manager Tool

– Formulas->Name Manager– Can add, edit, or delete ranges names

• Use in Formula– Paste Names as documentation– Find name for formula

• Autocomplete will show range names, double click the name to fill it in

IMPORTING TEXT

• A text file is a data file that contains letters, numbers, and symbols only.

• A delimiter is a character used to separate data in a text file.– A tab-delimited file is a text file that uses tabs

to separate data.

40

IMPORTING TEXT

• Data->From Text• Delimited/Fixed Width• Delimiters• Formatting

41

TEXT MANIPULATION

• Convert Text to Columns– Data->Text to Columns– Just like importing text files

• CONCATENATE()– Combines text

42

CHANGING CASE

• PROPER()– Also known as title case– First letter of each word capitalized

• UPPER()• LOWER()

43

SUBSTITUTE

• SUBSTITUTE(text, old text, new text, n)– text: the text you want to make the

substitution to– old text: the text you want to remove– new text: the text you want to replace old text

with– n: which occurrence to change

• If n is not specified, all text matching old text will be replaced with new text

44

OTHER TEXT FUNCTIONS

• TRIM()– Removes leading and trailing spaces

• LEFT(text, n)– Returns the leftmost n characters of text

• RIGHT(text, n)– Returns the rightmost n characters of text

• MID(text, start, n)– Returns n characters of text, starting with the

character in the position specified by start

XML

• eXtensible Markup Language• Each piece of data has a tag that specifies

what it represents• A tag is like a label• HTML is a specific form of XML with

limited tags (<h1>header</h1>, <b>bold</b>, etc.)

• XML can have any tag

47

XML SYNTAX

• Element– Start tag, end tag, and data

• Tags– Tags use angled brackets <>– End tags must have the same name as the start tag, but

are prefixed with a /– <example>data</example>– Tags are case sensitive so you can’t end an <example>

with </Example>

• Comments <!-- comment tags do not need an end tag -->

48

XML IMPORT

• Data Ribbon->From Other Sources->From XML Data Import

49

CUSTOM XML IMPORTS

• File->Open->Select XML File• Choose “Use the XML Source task pane”• Drag elements to the desired cells• Right click on the XML area, XML->Import

and select the XML file again• Excel will import the data in the format you

laid out

ATTENDANCE

• Record from the classroom Computers• Otherwise it will show FRAUD.
