Excel provided one most important keyword that is COUNT function. COUNT Functions used to count total number of cells in a selected range of data. COUNT function's return total number only those cells that contain numbers. COUNT function ignores empty cells or those contain text. If a number is later added to an empty cell or inserted into new row then function will be automatically updated to include this new data. 

Figure 1:

 COUNT function formula

=COUNT (range) 

For example calculate total number of sales Person then formula become as below

=COUNT(B4:B9)

Result: 6 

See Figure 2.

COUNTIF 

The COUNTIF function combines the IF functions and COUNT function in Excel. This combination return number of times specific data is found in a selected group of cells. The IF portion of the function determines what data meets the specified criteria and the COUNT part does the counting. 

COUNTIF function formula 

=COUNTIF (range,condition) 

For example calculate total number which value greater than $15000from column “Total” then formula become as below 

=COUNTIF(G4:G9,F14) 

Result: 3 

F14 is a cell index where we have defined condition. 

See Figure 2. 

COUNTIFS 

Excel's COUNTIFS function can be used to count up the number of data records in a selected range that match specific criteria. COUNTIFS function allowing you to specify from 2 to 127 criteria rather than just one as in COUNTIF. 

COUNTIFS function formula

=COUNTIFS (range, range, …..n) 

For example calculate total number which value greater than $5000from “January”, $6000 from “February” and $7000 from “March”column then formula become as below 

=COUNTIFS(D4:D9,F15,E4:E9,G15,F4:F9,H15) 

Result: 1 

F15, G15, H15 are a cell index where we have defined formula. 

See Figure 2.

MAX

MAX function will be return maximum numeric value from selected range 

MAX function formula

=MAX(Range) 

For example I want to find out maximum value from moths column (January, February, March) then formula become as below 

=MAX(D4:F9) 

Result: $9,568.00 

See Figure 2. 

MIN 

MIN function will be return minimum numeric value from selected range 

MIN function formula

=MIN(Range) 

For example I want to find out minimum value from moths column (January, February, March) then formula become as below 

=MIN(D4:F9) 

Result: $1,205.00

See Figure 2.
