• Microsoft Office Excel is a powerful tool used to create and
format spreadsheets.
• Spread-sheets allow information to be organized in rows and
tables and analyzed with automatic mathematics.
• Spreadsheets are commonly used to perform many different
types of calculations.

1. File Menu and Backstage View - This view contains all the new, open, creation,
save, save as, share, and print options for your worksheets
2. Quick Access Toolbar (QAT) - This is a customizable toolbar placed by default on
the top of Ribbon ,you can add icons for your often used commands to this toolbar
3. Ribbon - It has tabs which contain groups of buttons for various options
4. Name Box - Displays the name of the cell .The cell name is a combination of the
column letter and row number.
5. Formula Bar - Displays the formulas or text written in a cell
6. Sheet Tabs - Displays a list of Sheet names
7. Worksheet Area
Note : There are 10,48,576 Rows and 16,384 Columns in an MS Excel 2010 Worksheet.

5. Whenever you want to perform any calculation based on a certain condition, you use an If
Function.
Syntax :
= IF(Logical_test,[Value_If_True],[Value_If_False])
Logical_Test - The condition that you want the function to evaluate
Value_If_True - The value to be returned if the condition is satisfied
Value_If_False - The value to be returned if the condition is not satisfied

Logical
Test
Value If
True Value If False

The And function is a logical function which returns TRUE if all conditions are TRUE. It
re-turns FALSE even if any one of the condition is FALSE.
Syntax :
=IF(And(logical1,logical2…),[Value_If_True],[Value_If_False])
Logical - The condition that you want the function to evaluate
Value_If_True - The value to be returned if the condition is satisfied
Value_If_False - The value to be returned if the condition is not satisfied
Logical
Test
Value If
True
Value If False

The OR function is a logical function which returns TRUE even if any one of the
condition is TRUE. It returns FALSE only if all the conditions are FALSE.
Syntax
=IF(Or(logical1,logical2…),[Value_If_True],[Value_If_False])
Logical - The condition that you want the function to evaluate
Value_If_True - The value to be returned if the condition is satisfied
Value_If_False - The value to be returned if the condition is not satisfied

8. Counting numbers
 “count” function is use to count number of cells with numbers
 Alphabets and alphanumeric are not counted
8
Alphabe
t
Only 1 number
in the count
range
Number

“count”

9. Counting data cells
 “counta” function is used to count all cells which are filled with data
9
Function
“counta”
Unfilled cell

Mixed
data
Range size
10
Total count
9
Space “ “ is also treated as data

10. Conditional Counting
 “countif” function is used for conditional counting
 Conditions like
 Greater than, less than, equal, not equal
 Only alphabetic and alpha numeric filed

If the cell is blank or contains text, the cell will not be used in the average
calculation. If the cell contains zero , the cell will be included in the average
calculation.
Syntax :
=AVERAGE(Range1,Range2,Range3... through to Range30)
Rather than using a combination of Sum and Counta
function , Average function can be used.

13. 13
This function joins separate pieces of text into one item.
Up to thirty pieces of text can be joined using this function.

This function is
extensively
used for
punctuation.
Can be used
for more than
2 words also

16. 16
This function shows the current date and time. The result will be updated each
time the worksheet is opened and every time an entry is made anywhere on the
worksheet.
Syntax :
= Now()
The result will be shown as a date and time. If it is formatted to show as a number
the integer part is used for the date and the decimal portion represent the time.

17. 17
Upper Function
This function converts all characters in a piece of text to upper case.
 Syntax :
= UPPER(Text To Convert)
Lower Function
This function converts all characters in a piece of text to lower case.

Combination of
Numbers and letters is
also a valid input
Irrespective of preceding
nos. function operates
properly.

18. 18
Left Function
This function displays a specified number of characters from the left hand side of a
piece of text.
 Syntax :
= LEFT ( Original Text , No Of Char Required)
Right Function
This function displays a specified number of characters from the right hand side of
a piece of text.
 Syntax :
= RIGHT ( Original Text , No Of Char Required)

19. 19
Max Function
This function picks the highest value from a list of data.
 Syntax :
= MAX(Range1,Range2,Range3... through to..)
This table
indicates
max sales
amongst
regions
This array is

both can be used
to sort dates too.

21. 21
Sum Function
This function creates a total from a list of numbers. It can be used either
horizontally or vertically. The numbers can be in single cells, ranges etc.

can be applied
on row wise
basis.
Sum function
can be
applied
coloum wise
basis.

Sum with Offset Function
This is used when it is necessary to base a calculation on a set of cells in
different locations. The =OFFSET() picks out a cell a certain number of cells
away from another cell.
 Offset Function :
The =OFFSET() needs to know three things
1. A cell address to use as the fixed point from where it should base the offset.
2. How many rows it should look up or down from the starting point.
3. How many columns it should look left or right from the starting point.

This function raises a number to a user specified power.
• Syntax:
=POWER(Number To Be Raised, Power)
.
It is the same as using the
^ - caret operator, such as
3^4, which result is 81.
Both the POWER()
function and the ^
(caret) operator are
the same as using
3*3*3*3.

27. 27
This function picks from a list of options based upon an Index value given to
by the user.
• Syntax:
=CHOOSE(UserValue, Item1, Item2, Item3 through….)
Same formula can be sued on Numbers as well. User
Value
User

• Use Vlookup when the database is verticle
• VLOOKUP stands for vertical lookup
• Syntax
= vlookup(lookup_value,table_array,col_index_num,range_lookup)
Lookup_Value – It is the value that you are looking for.
Table_Array – It is the source database, from where you will get the data.
Col_Index_Num – It is the column number of that column in the table array from
which the values has to be returned.
Range_lookup – it specifies whether you want VLOOKUP to find an exact match or
an approximate match. If range lookup is set as False or 0, Vlookup will find an exact
match. If range lookup is set as True or Vlookup will find the nearest value that is less
than the lookup value.

• Use Hlookup when the database is horizontal
• Hlookup function searches for a value in the top most row of a table, and then
returns a value in the same column from a row you specify.
• HLOOKUP stands for horizontal lookup
• Syntax
= hlookup(lookup_value,table_array,row_index_num,range_lookup)
Lookup_Value – It is the value that you are looking for.
Table_Array – It is the source database, from where you will get the data.
row_Index_Num – It is the row number of that row in the table array from which the
values has to be returned.

Rept Function
This function repeats a piece of text a specified number of times.
• Syntax
= REPT(Text To Repeat , Repetitions)
You need to specify the text to be repeated and how many times to repeat it for this
function to be executed.
Rather than using cell
references you can
directly enter text to
repeat and repetitions

33. 33
Convert Function
This function converts a value measure in one type of unit, to the same value
expressed in a different type of unit.

GCD can also be
termed as HCF i.e
Highest Common
Factor.The result is
always a whole
number. Where
there is no
common divisor
the value of 1 is
GIVEN AS
OUTPUT.
36c

37. Quotient Function
This function calculates the number of times a number can be divided by
another number. This function calculates the largest number which can be used
to divided all the values specified.
• Syntax :
