 # Function List For Excel and Google Sheet

Last Updated on 2021-09-23

Functions are predefined formulas in Excel. A formula is an expression that calculates values in cells.
To start a function, you have to start with “=”. And once we input some parameters, it will show us the result.

Before we get started, try to familiarize yourself with HOTKEYS.

## Basic Hotkey

• Insert columns or rows : Ctrl + “+”
• Delete columns or rows : Ctrl + “-”
• Look for and replace : Ctrl + F
• Inconsecutive select : Ctrl + mouse
• Fill in downward with forluma : Ctrl + D
• Fill in rightward with forluma : Ctrl + R
• Select all : Ctrl + A
• Save file : Ctrl + S
• Close file : Ctrl + W
• Zoom in and out : Ctrl + mouse wheel
• Switch between Relative and Absolute reference : F4

## Common Function

### SUM

You can write like this : B3+B4+B5+B6+B7. Use the mouse to select the cells in range like
“=SUM( selected cells )”
Another way to do it is “=SUM( B3 : B7 )”

### MIN

Purpose : To find out the minimum value within selected cells. Use the mouse to select the cells in range like
“=MIN( selected cells )”
Another way to do it is “=MIN( B3 : B7 )”

### MAX

Purpose : To find out the maximum value within selected cells. Use the mouse to select the cells in range like
“=MAX( selected cells )”
Another way to do it is “=MAX( B3 : B7 )”

### COUNT

Purpose : To count how many cells are there. Use the mouse to select the cells in range like
“=COUNT( selected cells )”
Another way to do it is “=COUNT( B3 : B7 )”
The result will be 5(B3 to B7) in this case.

### COUNTA

Purpose : To count how many cells are there ( Only cells with a value that counts ). Use the mouse to select the cells in range like
“=COUNTA( selected cells )”
Another way to do it is “=COUNTA( B3 : B7 )”

### AVERAGE

You can write like this : (B3+B4+B5+B6+B7)/5. Use the mouse to select the cells in range like
“=AVERAGE( selected cells )”
Another way to do it is “=AVERAGE( B3 : B7 )”

### RANK

Purpose : To find out what is the ranking of the value in the selected cell. Use the mouse to select the cells in range like
“=RANK( the selected cell, reference range, ascending / descending sort )”
Another way to do it is “=RANK( B3, \$B\$3 : \$B\$7, 0 / 1 )”
PS. Ascending sort : 1 / Descending sort : 0

### IF

Purpose : If it meets the condition, output A result, otherwise output B result.
“= IF ( Judgement/Condition , meet the condition output A result , otherwise output B result )”
For example :
Then, the student is getting grade A if the number is bigger than or equal to 90, otherwise is grade B. Grade A and Grade B can also be replaced with cells that are filled with formula or even empty(it shows blank then).

However, it seems a bit unreasonable to give Bs to all the students who get grades under 90, doesn’t it? We can try to solve this by using multiple layers of IF. For example :
And it can go on and on and on for infinity.

### IFS

Now we’re thinking that there are so many IF. Is there a way to solve this formula and make it easier?
Here comes IFS :

Purpose : If it meets the condition, output A result, otherwise output B result. It’s a clean and easy function for humans to read.
“= IF ( Condition A , Output result A , Condition B , Output result B , Condition C , Output result C , otherwise result D )”
For example, we can rewrite IF to IFS as below :

### SUMIF

Purpose : Sum up the values among selected cells with a designated condition such as the brand’s sales number.
“= SUMIF ( Condition Range , Designated Condition , Calculate Range )”
For example :
= SUMIF ( \$B\$2 : \$B\$6 , “HP” , \$C\$2 : \$C\$6 )
Refer to the below chart, the result of the above formula will be 2600+2400=5000.

### AVERAGEIF

Purpose : Calculate the average among selected cells with a designated condition such as the brand’s sales number.
“= AVERAGEIF ( Condition Range , Designated Condition , Calculate Range )”
For example :
= AVERAGEIF ( \$B\$2 : \$B\$6 , “HP” , \$C\$2 : \$C\$6 )
Again, refer to the below chart, the result of the above formula will be (2600+2400)/2=2500.

### COUNTIF

Purpose : Count the number of cells among selected cells with a designated condition such as the brand’s sales number.
“= COUNTIF ( Condition Range , Designated Condition )”
For example :
= COUNTIF ( \$B\$2 : \$B\$6 , “HP” )
Refer to the below chart, the result of the above formula will be 2.

### IFERROR

Purpose : To beautify the error message due to any reason but mostly caused by something went wrong in the formula.
“= IFERROR ( Under normal condition showing the correct result , When error messages occur showing the way you wanted )”
Referring to the below chart, D6 cell is showing an error message. We could do this for example :
= IFERROR ( B2 * C2 , “Invalid Data” ) D6 will be showing “Invalid Data”
= IFERROR ( B2 * C2 , ” ” ) D6 will be showing ” ” – empty blank

### VLOOKUP

Purpose : To find out the specific values we wanted from a large amount of raw data and place them in our arrangement/will.
NOTE : It is very important to know how to switch between Relative and Absolute references by using “F4”.
Absolute reference : \$ was shown in front of it. Relative reference : There is no \$ sign.
Since Vlookup function is kind of complicated, I’ve found a video that is very easy to understand with his explanation.
