Entering Data in Worksheet:
Entering Data in a Cell:
The data can only be entered in the active cell, so following are the steps that
have to be performed for entering the data into a cell.
(a)
Make the cell active, in which you want to enter the data, by moving the cell
pointer to the desired cell.
(b)
Enter the data, using keyboard. Note that when you keyin the data then it
gets entered in formula bar, a copy of it gets displayed in the current cell
also. Any changes that you make in the data will have to be made in the
formula bar.
(c)
Press Enter or click the tick mark button, which appears in the Formula bar.
Basically there are two types of entries, which can be made in any cell. They
are categorized as follows:
(a)
(b)
(a)
Constants
Formula
Constants:
Constants can be defined as data, whose values do not change, unless you
physically change them yourself. For example, if you write "12500" in cell B1 then
the value "12500" will be treated as constant. Similarly if you write “Sales” in cell
D1 then the text "Sales" will be treated as constant. Constant entries can further be
classified into four categories as follows:
i.
Numbers
ii.
Text
iii.
Date
iv.
Time
2.
(i) Entering Numbers 
Numbers are the basic data for any worksheet. They are
often referred to as constant value or simply value. Any valid number is a
combination of ten digits i.e. from 0 to 9 and few special characters like +
(
)
/
$
%

etc.
Excel supports negative, commas, dollar signs and scientific notations. For
Example, some valid constant numbers are: 159, 168.89, 10 e 6, $750, 188, and
1,302. All the numbers that you enter, by default, get right aligned in the cell.
(ii) Entering Text  Text is generally used to put the labels so that the data of a row
or column could be identified. Any data, which is neither number, nor date or time
is treated as Text. For example, "JAN", "FEB", "Lucknow" etc. A cell can hold up
to 255 characters.
The text that you enter in the cell always gets left aligned in the cell.
(iii) Date and Time – The date and time can be entered as independent entities.
(b)
Formula:
Formula is a function, which comprises of constant values, function and
mathematical operators. The basic objective of defining the formula is to calculate
the values automatically. Mostly formulae are defined to manipulate numerical
values but some times they are utilized to manipulate date, time and text also.
For example (A1+B1)*60 is a valid formula, which instructs Excel to add the
values in cell A1 and cell B1 and then multiply it by 60. If we enter 5 in A1 and 6 in
cell B1 then Excel interprets the formula as (6+5)*60 which results in 660. In fact,
this formula has to be entered as =(A1+B1)*60. The formula that you enter in Excel
can be up to 255 characters long.
Excel formula can be classified into three categories:
(a)
Numeric Formula
(b)
Logical Formula
(c)
Text Formula
(a) Numeric Formula 
Numeric formulae are created for performing arithmetic
operations on cell values. A formula that uses arithmetic operators will be
categorized as numeric formula. The arithmetic operators are +, , *, /, %, and ^.

For example, Following are valid numerical formula:
(a)
=(A1+B1+C1)
(b)
=(B1+C1)
(c)
=(B1+C1)D1
(d)
=(A1+B1)*10%
(e)
=(3^2)+B1
(b) Logical Formula  Logical formulae are the formulae that are formed for
performing comparison operations. The result of comparison is displayed as TRUE
or FALSE. Any formula that contains logical operators (< <= > >= = <>) is termed
as logical formula.
For Example, say the cell B1 contains the value 500 and the cell A1 contains 200
then following logical formula will have results as displayed below:
Formula
=(B1<A1)
=(B1>A1)
=(B1=A1)
=(B1<>A1)
(d)
Result
TRUE
FALSE
FALSE
TRUE
Text Formula  Text formulae are written to join two or more strings
of characters. Any formula that contains text operator is called Text
formula. "&" is a text operator (called concatenation operator) which
joins two or more strings.
For example, if the cell A1 contains "Information" and B1 contains
"Technology"
then
the
formula
=A1&B1
will
produce
the
result,
"InformationTechnology". Note that there will be no gap between Information and
Technology. Say the cell C1 has one blank space in it then the
formula=A1&C1&B1 will result into "Information Technology”.
Editing a Workbook:
Making error is a common phenomenon in data entry operation, but before
worksheet is finalized, all the mistakes have to be rectified. Excel provides many
powerful editing features as follows:
Opening an Existing File:
3
4.
Select File option from bar menu, Excel displays a submenu. Select Open,
which will display a dialog box. From this dialog box, select the drive, folder and
the name of the file that you have to open. Select Open button from this dialog box.
On selecting this button, Excel will load the selected file and place you in the first
worksheet of the workbook. Once you have been placed in the worksheet, you can
move around in the worksheet or workbook and work with any cell of the
worksheet.
Editing the Contents of a Cell:
To edit the contents of a cell, simply click the mouse at that cell and its
contents will appear in the formula bar. Now the contents can be modified either
in the formula bar or in the cell itself.
Modifying the Contents in Formula Bar:
To modify the contents in the formula bar, take the mouse pointer there. As
soon as you point the mouse pointer in the formula bar, its shape changes to that of
Insertion Pointer. Using, either arrow keys or mouse you can place the insertion
pointer at the desired place and modify the contents with the help of keyboard.
Modifying the Contents within the Cell:
To modify the contents within the cell, double click on the cell, whose
contents have to be modified. As soon as you double click on the cell, mouse
pointer will change to Insertion Pointer. you can edit the contents of the current
cell and after modifying the contents, press Enter key.
Apart from editing the contents of the cell, there are various other
activities to be performed e.g. copying the cells, moving the cells, inserting rows,
inserting columns etc.
Selecting a Cell or Group of Cells:
A cell can be selected by moving the cell pointer to that cell. Recall that
when you select a cell, it's border gets outlined by a thick frame. On the right hand
side lower corner of which, appears a black square spot. This spot is called Handle.
The exact shape of the selected cell is illustrated below for you reference.

Following steps are
observed to select a group of cells:
1. Click the mouse on the first cell of the range.
2. Drag the mouse over all the cells of the range.
3. Release the mouse on the last cell of the range.
This process will select the desired group of cells and the selected cells
will get blackened/dark, indicating that this is the portion, which has been selected
for operation.
If you click the mouse outside the selected then the entire range gets
deselected.
