Excel is Product of Microsoft:

An Excel Workbook consists of many worksheets to perform these calculations. A worksheet is made up of Rows and columns. Intersection of a Row and Column generate a cell.

Formatting Cells:

Each cell in a worksheet can be formatted. Changing the format of a cell doesn’t affect the cell value.
There are six tabs in the “Format Cells” window. All formatting options may be found on these tabs. Multiple cells can be formatted in one step by first selecting the cells and applying formatting.

Merge and Centre

Merging cells is used when a text is to be centered over a particular section of a spreadsheet. When a group of cells is merged, then the text of this cell is merged as per selection and aligned center.

Numbers Group

A number format does not affect the actual cell value that Excel uses to perform calculations. The actual value is displayed in the formula bar. By applying different number formats, we can display numbers as percentages, dates, currency, and so on.

Number Formats available in MS Excel:

PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 7

Styles in MS Excel:

A style is just a set of cell formatting settings. All cells to which a style has been applied look the same according to formatting. When we change a part of a style, all cells to which that style has been applied also change their formatting accordingly to new style.

Conditional Formatting

Conditional Formatting is a tool in MS Excel that allows applying formats to a cell or range of cells. It also allows formatting change depending on the value of the cell or the value of a formula.

Formulas & Functions:

To maximize the capabilities of Excel, it is important to understand how to create simple formulas.
Creating simple formulas:
Excel uses standard operators for equations, such as a plus sign for addition (+), minus sign for subtraction (-), asterisk for multiplication (*), forward slash for division (/), and caret (A) for exponents. All formulas must begin with an equals sign (=).

To create a simple formula in Excel:
1. Select the cell where the answer will appear.
2. Type the equals sign (=).
3. Type in the formula we want Excel to calculate.
4. Press Enter. The formula will be calculated, and the value will be displayed in the cell.

Creating formulas with cell references:

When a formula contains a cell address, it is called a cell reference. Creating a formula with cell references is useful because you can update data in our worksheet without having to rewrite the values in the formula.

To create a formula using cell references :

  1. Select the cell where the answer will appear.
  2. Type the equals sign (=).
  3. Type the cell address that contains the first number in the equation.
  4. Type the operator we need for our formula. For example, type the addition sign (+).
  5. Type the cell address that contains the second number in the equation.
  6. Press Enter. The formula will be calculated, and the value will be displayed in the cell.

Edit a Formula:

A formula in excel can be edited as per requirement.

  1. Click the cell we want to edit.
  2. Insert the cursor in the formula bar and edit the formula as desired. We can also double-click the cell to view and edit the formula directly from the cell or press F2 key.
  3. When we’re done, press Enter or select the Enter command.

Cell Reference:

Cell Reference is termed to calculate important calculations by using a cell or a range of cells for a formula to calculate the result of the formula in a worksheet. We can use a cell reference for a single formula or for multiple formulas.

PSEB 9th Class Computer Notes Chapter 2 MS Excel Part-I

Types of Cell Reference

  1. Relative Reference.
  2. Absolute Reference.
  3. Mixed Reference.

1. Relative Reference:

In Excel Relative reference is used by default. When it is copied to multiple cells then it changes according to cell position.
1. Type data in a worksheet.
2. Now type our formula in cell B1 = A1 * 10.
3. Drag the fill handle of cell Bl, we will see that the formula becomes in celi B2 = A2 * 10.
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 26

2. Absolute Reference:

Sometimes we want that during copying a formula from, one cell to another, its cell reference should not be changed. In this case Absolute Reference is used. Dollar($) sign is used during typing a formula using Absolute Reference. Dollar($) sign can be used either for a row or a column. We can also use it for both together.
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 27
1. Type data in a worksheet.
2. Now type our formula in cell B1=$A$1 + 5
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 28
3. Drag the fill handle of cell C1, we will see that the formula becomes in cell B2 = $A$1 + 5.
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 29

3. Mixed Reference:

Mixed Reference is the combination of both Relative and Absolute Reference. In Mixed Reference a Dollar($) sign is used either to a Row or Column.
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 30

Basic functions:

A function is a predefined formula that performs calculations using specific values in a particular order. They can save our time because we do not have to write the formula yourself. Excel has hundreds of functions to assist with our calculations.

The parts of a function

The order in which we insert a function is important. Each function has a specific order – called syntax – which must be followed in order for the function to work correctly.
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 31
1. First of all equal to (=) sign is written.
2. After this the function name is written.
3. After this argument is written. Arguments contain the information we want the formula to calculate, such as a range of cell references.

PSEB 9th Class Computer Notes Chapter 2 MS Excel Part-I

Working with arguments:

Arguments are a vital-part of a Function.
1. Arguments must be enclosed in parentheses.
2. If there are Individual values or cell references inside the parentheses are separated by either colons or commas. Commas separate individual values, cell references, and cell ranges in parentheses.
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 32
3. If there is a ceil range in argument then it is written with colon in braces. Colons create a reference to a range of cells.

To create a basic function in Excel

1. Select the cell where the answer will appear (J3, for example).
2. Type the equals sign (=), then enter the function name (SUM, for example).
3. Enter the cells for the argument inside the parentheses.
4. Press Enter, and the result will appear.

Using AutoSum to select common functions

The AutoSum command allows us to automatically return the results for a range of cells for common functions like SUM and AVERAGE.
1. Select the cell where the answer will appear.
2. Click the Home tab.
3. In the Editing group, click the AutoSum drop-down arrow and select the function we want.
PSEB 9th Class Computer Notes Chapter 1 MS Excel Part-I 33
4. A formula will appear the selected cell.
5. Press Enter, and the result will appear.

1. Text Functions:

  • Clean: This Function removes all non-printable characters from asupplied text string.
  • Trim: This Function removes duplicate spaces, and spaces at thestart and end of a text string
  • Concatenate: This Function Joins together two or more text strings
  • Left: This Function returns a specified number of characters fromthe start of a supplied text string
  • Mid: This Function Returns a specified numberfrom the middle of a supplied text string
  • Right: This Function Returns a specified numberfrom the end of a supplied text string

2. Logical Functions:

IF: This Function tests a user-defined condition and returns one result if the condition is TRUE, and another result if the condition is FALSE

3. Date and Time Functions:

  • Date: This Function returns a date, from a user-supplied year,month and day
  • Time: This Function returns a time, from a user-supplied hour, minute and second
