lookup functions
Lookup Functions
  • Lookup functions are used to look up values in a table to perform calculations or display results
  • A Lookup table is a range that contains data for the basis of the lookup and data to be retrieved.
vlookup
VLOOKUP
  • Used to gauge an entered value against a range of corresponding results
  • Well suited for large tables of data, such as tax tables
  • Also to convert the number grades into letter grades
  • Has three mandatory arguments
vlookup contd
VLOOKUP(contd.)
  • Syntax

=VLOOKUP(lookup value , lookup table , column index number , [range lookup])

  • The lookup value ─ value to look up in a reference table
  • The lookup table ─ a range of cells containing the reference table
  • The column index number ─ the column number in the lookup table that contains return values
example
Example

Converting the

Number grades to

the letter grades

hlookup function
HLOOKUP Function
  • The HLOOKUP function is used when the breakpoints and return data are placed in rows
  • The third argument now lists the row index
financial functions
Financial Functions
  • Used for decisions involving payments, investments, interest rates, etc.
  • Allows you to consider several alternatives
  • PMT
pmt function
PMT Function
  • Used to calculate loan payments
  • Has three arguments:
    • the interest rate per period
    • the number of periods
    • the amount of the loan
  • Computes the associated payment on a loan
pmt contd
PMT(contd.)
  • Syntax:

Pmt( interest_rate, number_payments, PV, [FV],[Type] )

  • Example:
    • Pmt(7%/12, 2*12, 5000, 0, 0)
    • returns the monthly payment on a $5,000 loan

at an annual rate of 7%. The loan is paid off in

2 years (ie: 2 x 12).

    • E2 - 7% ; E3 - 24 ; E4 - $5,000.00
    • PMT ( E2/12 , E3 , - E4 )
range names
Range Names
  • A range name is a word or phrase used to identify a cell or cell range
  • Range names make formulas easier to read
  • Range names use the following rules:
    • 1to 255 characters
    • Begin with a letter or underscore (_)
    • Contain letters, digits, period, underscore.
creating and maintaining a range name
Creating and Maintaining a Range Name
  • Type the range name in the Name Box area
  • Enter the name using New Name dialog box
  • Name Manager dialog box is used to edit or delete a range name
  • Insert a table of Range Names ( Use in Formula -> Paste Names)
rank function
Rank Function
  • The RANK function is useful for producing a ranking by using a formula
  • Syntax

=RANK(number, range, order)

number: the number/cell for which you want to find the ranking within the “range”

range: range of numbers/cells within which the “number” will be ranked

order: not really required for our purposes. Leave it blank do not put anything.

rank function example
Rank Function Example
  • Insert a Rank function in cell D3
  • Type =rank(c3,c3:c8)
  • Autofill the formula to remaining cells. Observe the cell references and make the references absolute
  • =rank(c3,$c$3:$c$8)
conditional formatting
Conditional Formatting
  • Formats the data in excel sheet if and only if the data satisfies the condition.
  • We wish to apply conditional formatting for the values in column3
  • Select all the values in column3

->Click on conditional formatting in styles group

->Give the condition

importing
Importing
  • Importing –Inserting data from one application or file into another.
  • Text, CSV, XML and Database files are the commonly imported files.
  • Before importing we have to check if we want to manage the data as a separate entity in Excel or you want a connection to the original data source/application.
text files
Text files
  • The text file has .txt extension and contains only text (alphabets, numbers and symbols).
  • We must choose a delimiter for importing.

Ex: Space, tab or Comma etc

  • Columns align according to the delimiters.
csv files
CSV Files
  • CSV abbreviated as Comma-Separated Values

Text Manipulation
  • Other text functions
xml files
XML Files
