# 10 Best formulas in Excel

Excel has provided a vast formula to perform different operations.

## 1. Sum

Syntax

Sum(Number 1, Number 2.,Number 9) or SUM( Starting location of data: Last location of data)

Example

sum(20,30,40) = 20+30+40 = 90

=SUM(A1:A8) = add all numbers updated in column A from row 1 to 8 =SUM(A1:B8) = add all numbers updated in column A and column B from row 1 to row 8. ## 2. Count

Used to count numbers in the selected range.

Syntax

COUNT( Value 1, Value 2, …. , Value N) or COUNT(First cell of data range: Last cell of data range)

Example

COUNT(B1:B16) is equal to the count of numerical data points in column B from row 1 to row 16. ## 3. Average

Used to average/mean of the given set. I,e the sum of all data points divided by the count of data points.

Syntax

AVERAGE(Value 1, Value 2…., Value N) or COUNT (First cell of data range: Last cell of data range)

Example

=AVERAGE( B1:B16) = SUM( B1:B16)/COUNT(B1:B16)

This function will not consider empty cells and non-numeric cells. ## 4. IF Function

IF function is used to perform the required action if a predefined condition is either TRUE or FALSE.

IFERROR is used to manage error evaluated while performing another function.

Syntax

If ( Logical condition, Value_if_true, Value_if_false)

IfERROR(value, value_if_error)

For example if Function to return True or False =IF(B4>30,"True","False") ## 5. VLOOKUP

used to find a required value in a table in a corresponding referred now

Syntax

VLOOKUP(Lookup_value, table_array,col_index_num),[range_lookup]

Example

Let's look up the price of Volvo from the following list. Use =VLOOKUP(A11,A1:B8,2,FALSE) ## 6. Offset

Returns a reference to a range that is a specified number of rows and columns from a cell or range of cells.

Syntax

OFFSET(reference, rows, cols,[height],[width])

Example ## 7. COUNT employees

From the data, calculate the count of data equal to, not equal to, less than, or higher than a given number. COUNTIF can be used.

Example

Cells equal to 20.

=COUNTIF(B2:B16,F13) ## 8. MAX, MIN

MAX will return the largest numeric value of the range, MIN will return the smallest numeric value of the range. They will include only numeric values

MAXIF MINIF will return the largest and smallest values respectively only among the cells.

Syntax

MAX (Range); MIN(Range);

MAXIF([Max_Range], Criteria Range 1, Criteria Range 2, Criteria Range N)

MINIF [(MIN_Range], Criteria Range 1, Criteria Range 2, Criteria Range N)

Example

Example lets find the largest value =MAX(B2:B16) ## 9. Round

The ROUND function is used to round numbers to a specified number. ROUNDUP, ROUNDDOWN can be used to round numbers away from Zero.

Syntax

ROUND(Number, digit)

ROUNDUP(Number, digit)

ROUNDDOWN(Number, digit)

Example

For Example, let's round down a number to 1 decimal place =ROUNDDOWN(B4,1) ## 10. Replace

Used to search and replace a character to the text

Syntax

REPLACE(old_txt, Start num,num_char_to_replace, new text)

For example, let's replace the last 2 characters with an empty string. Use =REPLACE(A2,6,2,"")
