A comprehensive guide to Excel formulas

Basic Arithmetic Formulas

Excel provides simple arithmetic formulas for addition, subtraction, multiplication and division. These basic formulas are essential for performing calculations in your worksheets.

Add up

=A1 + B1

 

Subtraction

=A1 - B1

Multiply

=A1 * B1

 

Share

=A1 / B1

Text Functions and Formulas

Excel has a wide range of text functions that can help you manipulate and analyze text data. Some commonly used text functions are:

CONCATENATE

=CONCATENATE(A1, " ", B1)

 

This function merges text from different cells.

 

LEFT

=LEFT(A1, 3)

 

This function returns the specified number of characters from the beginning of a text.

RIGHT

=RIGHT(A1, 3)

 

This function returns the specified number of characters from the end of a text.

 

LEN

=LEN(A1)

 

This function returns the number of characters in a text.

Date and Time functions

Excel provides powerful date and time functions to help you work with these data types. Some commonly used date and time functions are:

TODAY

=TODAY()

 

This function returns the current date.

 

NOW

=NOW()

 

This function returns the current date and time.

DATE

=DATE(year, month, day)

 

This function converts a specified year, month and day to a date.

 

DATEDIF

=DATEDIF(A1, B1, "d")

 

This function calculates the difference between two dates in days, months or years.

Search functions

Search functions in Excel are very useful in finding specific values in your worksheets. Some commonly used search functions are:

VLOOKUP

=VLOOKUP(A1, B1:C10, 2, FALSE)

 

This function searches for a specified value in a table and returns a related value from the same row.

 

HLOOKUP

=HLOOKUP(A1, B1:C10, 2, FALSE)

 

This function works the same as VLOOKUP, but instead searches a row and returns a related value from the same column.

INDEX/MATCH

=INDEX(B1:B10, MATCH(A1, A1:A10, 0))

 

These functions work together to find a value in a table using the row and column labels.

Statistical Functions

Excel offers several statistical functions to help you analyze your data. Some commonly used statistical functions are:

AVERAGE

=AVERAGE(A1:A10)

 

This function calculates the average of a series of numbers.

SUM

=SUM(A1:A10)

 

This function sums the values in a series of cells.

COUNT

=COUNT(A1:A10)

 

This function counts the number of cells in a range that contain a value.

Logical Functions

Logical functions in Excel help you make decisions and perform actions based on certain conditions. Some common logical functions are:

IF

=IF(A1>10, "Yes," "No")

 

This function performs an action based on a certain condition.

 

AND

=AND(A1>10, B1<20)

 

This function returns TRUE if all the specified conditions are true.

OR

=OR(A1>10, B1<20)

 

This function returns TRUE if at least one of the specified conditions is true.

Conditional Formatting

Conditional formatting in Excel allows you to automatically change the appearance of cells based on certain conditions. Some common conditional formatting rules are:

Highlight Cell Rules

These rules allow you to mark cells based on certain conditions, such as cells that contain a certain number or cells that fall within a certain range.

 

Data Bars

These rules allow you to display a data bar in a cell based on the value of that cell.

Color Scales

These rules allow you to apply a color scale to a range of cells based on their values.

Data validation

Data validation in Excel allows you to apply certain rules to user input, such as limiting the values allowed or setting a minimum or maximum value for a cell. Some common data validation rules are:

List

This rule allows you to define a list of allowed values for a cell.

 

Whole Number

This rule limits user input to integers.

Decimal

This rule limits user input to decimals.

Pivot tables

Pivot tables are a powerful feature in Excel that allow you to summarize and analyze large amounts of data. Pivot tables allow you to quickly and easily understand your data and identify trends and patterns. Some common functions of pivot tables are:

Row Labels

This function allows you to group data groups by row.

 

Column Labels

This function allows you to group data groups by column.

Values

This function allows you to display the values you want to summarize.
