**SPREADSHEET**

Spreadsheet application is a computer program that allows us to record,calculate and compare numerical or financial data. A spreadsheet is a configuration of rows and columns. Rows are horizontal vectors while columns are vertical vectors.. LibreOffice Calc, MS Office Excel, Open Office Spreadsheet, etc. are examples of Spreadsheet software.

**Workbook**

A file in spreadsheet is known as a “Workbook”. A workbook is a collection of a number of “Worksheets”.

**Worksheet**

A page in a workbook is called Worksheet. It is a collection of cells where you can keep and manipulate the data. we can add as many worksheets as the memory capacity of our computer.

**LibreOffice Calc**

LibreOffice Calc is a spreadsheet application that you can use to calculate, analyse, and manage data. It includes in LibreOffice Package, which is Free and Open Source software under the General Public Licence (GPL)

**Features of LibreOffice Calc**

- Easy calculation:-

It can perform complex calculations with ease.

- What -if Calculations:-

Calc lets users to predict what will happen if certain conditions change.

- Serve as a Database:-

Huge volume of data can be organised , stored and filtered without much efforts.

- Arranging data asper user requirement:-

The stored data can be organised or reorganised according to the needs of the users.

- Can provide dynamic Charts:-

Different inbuilt charts and graphs are available for presenting the data in appealing manner.

**Components of LibreOffice Calc**

**Row**

A row is the range of cells that go horizontally in a worksheet. Rows are identified by numbers like 1, 2,3 and so on.There are 10,48,576 rows are in Calc.

**Column**

A column is the range of cells that go vertically in a worksheet. Columns are identified by letters like A, B, C and so on. When it reaches Z, the next columns are identified as AA, AB, AC and so on.In Calc there are 1024 columns named as A to AMJ in a single worksheet.

**Inserting Rows and Columns**

We can add or delete Rows and columns in a Spreadsheet. To add a column,click at the column header (right click on the mouse), there we get an option to add column. Likewise we can add row.

Insert column Insert row

**Cell**

Each rectangular box in a worksheet is referred to as a cell. In other words a cell is the intersection point of a column and row. Data entered into Calc is always stored in a cell. To keep track of where data is stored, each cell has a cell reference consisting of the column letter and row number of where the cell is located. Ex: A10

**Range**

Range is a group or block of cells. Ranges are identified by the cell references of the cell in the upper left and lower right corners of the range. These two references are separated by a colon ( : )

For example, the range D1:E10 includes a block of 20 cells starting from D1 and ending to E10.

**Naming Ranges**

This means giving a name to a specific range.For example , scores obtained by students in Accounting is given in in the range C2:C10 , you can name this range as “Marks” also this name can be used in formulas and functions instead of quoting cell range as C2:C10.

**Types of worksheet Data **

**1- Value**

Value is a number that you enter in a cell.Thus numerical data is called a value.It also include currency symbol,minus,plus signs,decimal points and comma.

**2- Labels**

The text data is called label.It includes alphabets and symbols.they are non-numeric data but may include digits also. Ex: Name, Date of Birth , Mark etc.

**3- Formula**

Formulas are self-defined instructions entered in cell for performing calculations. Formula should begin with an ‘= ‘ sign. Ex =A1+B1

**Components of a Formula**

A standard formula may have three components

- Cell Reference
- Mathematical operators
- Functions

**1 – Cell Reference**

To identify the location of a cell, a reference is given to a cell. It is also referred to as Cell Address. A cell reference or cell address consists of the column letter and row number that intersect at the cell’s location. Ex : A1,E11,X18

**Relative Cell Reference**

Normally, when a formula or function from one cell is copied to another, the references given in the formula or function automatically changes to suit the new locations. This type of reference is called Relative Reference.

**Absolute Cell Reference**

Unlike relative references, absolute references do not change when copied to another location. You can use an absolute reference to keep a row and/or column constant. An absolute reference is designated in a formula by the addition of a dollar sign ($). Ex: $A$1

**Mixed Cell Reference**

It is a combination of relative and absolute Cell references that holds either row or column constant when the formula or function is copied to another location.This is known as mixed reference. Ex:$A1 , B$10

**Basic and Derived Values**

If we directly enter a value or piece of data in a cell, it is called Basic Value. If the data in a cell is generated by an arithmetical expression or as the result of a function or formula, it is called derived value.

**2 – Mathematical Operators**

- Arithmetic
- Comparison
- Reference

Operation Performed | Operator Symbol |

Arithmetic OperatorsAdditionSubtractionMultiplicationDivisionPercentExponential | +–*/%^ |

Comparison OperatorsEqual toGreater thanLess thanGreater than or equal toLess than or equal toNot equal to | =><>=<=<> |

Reference Operators Range OperatorsUnion operators | :, |

**3 – Functions**

A function is a predefined formula which can be written directly into a cell, to display an outcome. which starts with ‘ Equal to sign’(=)Ex: SUM,MAX, MIN etc

**Important Predefined functions in calc**

- Date and time function
- Statistical Functions
- Logical Functions
- Mathematical Functions
- Text Functions
- Spreadsheet Functions
- Financial functions

**1- Date and Time functions**

This function is used to perform operations on date and time values..The important date and time functions are TODAY(),NOW(), DAY() ,MONTH(), YEAR(), DATEVALUE()

**TODAY()**

This function shows current computer system date in the cell.The current date is automatically returned when we open the document on a future date. its syntax is **=TOADAY ()**

**Eg**: in cell A1 if we enter =TODAY() it gives the result of today’s date ie, current system date. 26/09/2019

**NOW()**

NOW function displays the current system date and time. its Syntax is =NOW(). in cell A1 if we enter =NOW() it gives the result of today’s date and time, current system date and time. 26/09/2019 10:45

**YEAR()**

YEAR function returns the ‘year’from the date or date value given in the brackets. its Syntax is =YEAR(“Date” or Cell reference) It ranges from 1900 to 9999.For example in the above case Year(A1) results in 2019. Ie; the 2018^{th }year.

**MONTH()**

This function shows the serial number of the month ranging from 1 to 12. its Syntax is =MONTH(“date” or Cell reference).For example in the above case Month(A1) returns 9, i.e. the 9^{th }month

**DAY()**

it shows the day of the date.Its syntax is =DAY() (“Date” or cell reference). For example if A1 = 26/09/2019, the Day(A1) will result in 26. Because it is the 26^{rd }day of the month.

**DATE VALUE**

This function converts the given date to the corresponding value.LibreOffice calc considers 30/12/1899 as the base date with date value zero(0) .The syntax is =DATEVALUE(“ date”)

For example we enter in cell A1 =DATEVALUE(“26/09/2019”) It gives the result of 43734. There are 43734 days from 30/12/1899 to 26/09/2016.

**DATE**

This function returns a date, when the year ,month and day parameters are given as integer seperated by commas.

Syntax : DATE(Year,Month,Day)

Ex : DATE(2019,09,26) it is displayed as 26/09/19

**2- Statistical Functions**

Statistical function operates on a set of data and gives summarised results.

**COUNT()**

The COUNT function will count cells that contain numbers or count the numbers given in the arguments separated by commas.Only numbers,dates and time are counted here.

** The syntax is =COUNT(A1:B5) or**

** =COUNT(Value1; Value2; … Value30)**

** Value1; Value2, …** are 1 to 30 values or ranges representing the values to be counted.

**COUNTA()**

The COUNTA function counts the number of cells that contain any type of data. In other words it counts the number of cells that are not empty in a range. The cells that contain a formula, but the result as empty (” “) is also counted here.

**Syntax is =COUNT(A1:B5) **

** =COUNTA(Value1; Value2; … Value30)**

**Value1; Value2, …** are 1 to 30 arguments representing the values to be counted.

**COUNTBLANK()**

COUNTBLANK function counts the number of empty cells in a range. It is an opposite function of COUNTA. A cell that contains formula is not treated as empty, even if its result is empty.

**Syntax is =COUNTBLANK(Range)**

Returns the number of empty cells in the range.

**COUNTIF()**

This function counts the number of cells within a range that meet the given criteria or condition. here the blank cells and text values are ignored.

**Syntax is =COUNTIF(range,criteria)**

**AVERAGE**

Average is calculated by adding a group of numbers and then divided by the count of those numbers

Content in the Cell B1 | Content in the Cell C1 | Content in the Cell D1 | Function in Cell E1 | Result in Cell E1 |

20 | 30 | 40 | =AVERAGE(B1:D1) | 30 |

**MIN()**

It finds the smallest number in** **a set of values

Content in the Cell B1 | Content in the Cell C1 | Content in the Cell D1 | Function in Cell E1 | Result in Cell E1 |

20 | 30 | 40 | =MIN(B1:D1) | 20 |

**MAX() **

It finds the largest number in a set of values.

Content in the Cell B1 | Content in the Cell C1 | Content in the Cell D1 | Function in Cell E1 | Result in Cell E1 |

20 | 30 | 40 | =MAX(B1:D1) | 40 |

**3 – Logical Function**

Logical functions are used to compare two values or statements.The commonly used logical functions are IF,AND and OR

**IF()**

The IF function is one of the most popular and useful functions. IF function test a condition and to

return one value if the condition is true, and another value if the condition is false.

Syntax

**IF(Test, ThenValue, OtherwiseValue)**

**Test** is logical test.

**ThenValue** (optional) is the value that is returned if the logical test is TRUE.

**OtherwiseValue** (optional) is the value that is returned if the logical test is FALSE.

Marks | Function | Result |

50 | =IF(A2=>30,”PASSED”.”FAILED”) | PASSED |

25 | =IF(A3=>30,”PASSED”.”FAILED”) | FAILED |

**NESTED IF**

An “IF” within another ”IF” function statement, it is known as “NESTED IF”. If first condition is false it is checked next and if the second condition is false it is check next and so on.

Marks | Function | Result |

90 | =IF(A2>=90,”A+”,IF(A2>=80,”A”,IF(A2>=70,”B+”,IF(A2>=60,”B”,IF(A2>=50,”C+”,IF(A2>=40,”C”,IF(A2>=30,”D+”,”D”))))))) | A+ |

**AND**

This function checks more than one condition at the same time and returns TRUE if all the conditions are satisfied. Otherwise it Returns FALSE.

**Syntax**

**AND(LogicalValue1; LogicalValue2 …LogicalValue30)**

LogicalValue1; LogicalValue2 …LogicalValue30 are conditions to be checked. All conditions can be either TRUE or FALSE.

**OR**

Returns TRUE if any argument is TRUE; returns FALSE if all arguments are FALSE.

=ROUND(4.15,1) Rounds 4.15 to one decimal place 4.2.

**ROUNDUP()**

This function is similar to ROUND function.This function rounds a number up away from zero. If the number in rounding position is more than zero, it is rounded to the next.

Ex:

=ROUNDUP(1.1111,2) returns 1.12.

=ROUNDUP(1.2345,1) returns 1.3.

=ROUNDUP(45.67,0) returns 46.

=ROUNDUP(-45.67) returns -46.

=ROUNDUP(987.65,-2) returns 1000.

**7 – Financial functions**

This category contains the finance functions of LibreOffice Calc.

**ACCRINT**

Calculates the accrued interest of a security in the case of periodic interest.Accrued interest is interest due but not received/paid.Companies may pay interest on debentures or bonds periodically( quarterly,half yearly or yearly).If a holder sells his security before next interest due date,the buyer has to pay its market value and plus interest earned up to the settlement date. ACCRINT function helps to calculate such interest easily.

**Syntax**

ACCRINT(Issue,FirstInterest,Settlement,Rate,Par,Frequency, Basis)

**Issue** is the issue date of the security.

**FirstInterest** is the first interest date of the security.

**Settlement** – The settlement date of the security(ie. sold or purchased)

**Rate** is the annual rate of interest (coupon interest rate)

** Par** is the par value of the security.

** Frequency** is the number of interest payments per year (1 for annual, 2for half yearly and 4 for quarterly).

** Basis** (Optional) It indicates how the year is to be calculated.If the basis not given it is automatically counted as zero.

Basis | Calculation |

0 | US method (NASD), 12 months of 30 days each |

1 | Exact number of days in months, exact number of days in year |

2 | Exact number of days in month, year has 360 days |

3 | Exact number of days in month, year has 365 days |

4 | European method, 12 months of 30 days each |

**Example:**

On 1.Mar.2017, Mr.Suresh has invested Rs.5000 in a security having compound interest @10% annually. The next interest date of the security is 31-Dec-2017. But meanwhile on 24-April-2017 he sold the security to Mr.Mahesh. On 31st Dec 2017, Mr.Mahesh will get interest for the 9 months. But Mr.Suresh was the holder of the security for 54 days and hence Mr.Mahesh has to pay interest receivable for these days to Suresh, along with the market value of the security. This interest is

= 5000 X 10100X 54365= 73.97260274

**RATE**

Calculate the interest rate per period of an annuity.

Nper – Total number of payment periods

PMT – payment made each period.Given as minus figure.

Pv – the total amount

Fv – Future value or cash balance after the last payment

Type – 1 for beginning and 0 for the end of the period.

Guess – Is your guess for what the rate will be, by default it is 10%

Asha Menon taken a loan of 500,000 from CANARA Bank, agreed to pay

11,500 per month over a period of 5 years, and the monthly payments are to be made at the end of each month. Compute the rate of interest using Rate Function.

**CUMIPMT**

Returns the cumulative interest paid on a loan between two dates.

**Syntax**

**CUMIPMT(Rate, NPer, PV, S, E, Type)**

**Rate** is the periodic interest rate.(if annual rate is given,find monthly rate)

**NPer** is the length of loan in months (if given in years to be converted in to months).

**PV** is the current value in the sequence of payments.

**S** is the first period.

**E** is the last period.

**Type** is the due date of the payment at the beginning(1) or end(0) of each period.

Example :
