=SUM(A11:E11) – This formula will sums the values of selected rows.

=SUM(C1:C3,C5,C7:C8) – It will sums values from range C1 to C3, skips C4, adds C7, then add C7 and C8.

=SUMIF() -This SUMIF formula add cell values upon specific condition.

=SUMIFS() – In excel, SUMIFS function sum cell values depend upon multiple condition match.

Average Formula:

In excel, Average function calculate the average value of given numbers present in cells.

=Average(C3:E3)

=AVERAGE(A1:A5,A8,A12:A15) – Average with mixed arguments. it will provide average value of periodic selected cells only.

=AVERAGEIFS(C5:C14,D5:D14,”Kolkata”) -It will only average of numbers from kolkata.

Maximum Formula:

Find maximum value from given range.

=MAX(B1:D3)

Minimum value:

Thi formula find out smallest number from given range.

=MIN(B1:D3)

Product Formula:

This formula multiplies string value of any given range.

=PRODUCT(B1:D3)

Change Case:

Change Case is used to convert data into Uper, Lower or in Proper case.

• =UPPER(A2) – Display cell data in uppercase format.
• =LOWER(A2) – Display cell data in uppercase format.

• =COUNTIF(C2:C7, “Star”)
• =COUNTIFS(B3:B8,”Star”, A3:A8, “Kolkata”)

OR Operator Formula:

Select cell > =or(A2<=A3) [ Range of data cells & output is True of data]

Select cell > =or(A2=A3) [ Range of data cells & output is False of data]

Sqrt Formula:

Select the cell > =sqrt(A4) [ Range of data cells & output is square number of data]

Trim Formula:

This formula is used to remove extra spaces between words of a cell allow only one space.

• =TRIM(A1:D1)

Concatenate Formula:

This formula will join multiple cell data in one cell. Some examples-

• =CONCATENATE(B2&C2) | =CONCATENATE(B2,C2)
• =CONCATENATE(B2, ” “,C2) Add space ( space under quote) between two cell data.

Percentage Calculation:

Calculate 15% value of 850.

IF Function:

Example-1: Specify bonus, If salary Under 20000- MOBILE, If salary more than 20000- LAPTOP.

Example-2: Calculate Grade of mark sheet- TOTAL: 400=A, 300=B, 200=C, below 199=FAIL.

• =IF(C4>=400,”A”,  IF(C4>=300,”B”,  IF(C4>=200,”C”,”FAIL”)))
