Check if cell is empty or not - excel

I'm new to excel , I need to check if cell is empty put zero and if not don't change value
I tried to use =IF(" ",0,**)
But instead of ** I don't know How can i make it don't change the value?

try this
=IF(ISBLANK(A1),0,A1)
the problem with your formula is that there is no cell reference. Here we are checking the cell A1 if it is empty or not.
Update
Since it seems that the cell are not actually blank, try to use this formulae
=IF(TRIM(A1)="",0,A1)
You can actually join the two formula
=IF(OR(ISBLANK(A1),TRIM(A1)=""),0,A1)

Try this please, =IF(A1>0,A1,0) Please note: this will work on a different column, not the same.

condition formatting based on formula's result

I have a cell (AP21) containing a formula, and I want that the AP22 become black if the AP21 return empty string.
I am using conditionnal formatting but I not able to do that, because when I am using a formula to check the value of AP21, it's always considered as not empty because it contains a formula and not a text.
What I need is to evaluate in my AP22 the result of the formula of the cell AP21 and not the formula itself.
Any clue about how to do that please ?
Here is what I have to help you to understand me more
I tried also what is suggested in comments still didn't work
As #BigBen said in comments, you want to compare to an empty string
=$AP21=""

Keeping cell blank if now values is added in IF formula

I am trying set IF condition, the conditions are working fine, only issue I am facing is that whenever the cell is left empty the resulting cell is still showing "Pass", but I want to keep it blank if nothing is entered in the cell
=IF(B22<=2000,"Pass",IF(B22>2000,"Fail",""))
Try
=IF(B22="","",if(B22<=2000,"Pass","Fail"))
A nested ISBLANK function works well for this:
=IF(ISBLANK(B22),"",IF(B22<=2000,"Pass","Fail"))
Alternative solution:
=IF(B22,IF(B22<=2000,"Pass","Fail"),"")
Note: the value in cell B22 needs to be either a number or blank (cannot be text).
If the value (even if it is showing blank) in Cell B22 is returned by a formula, then you probably want to use the following formula instead:
=IF(LEN(B22)=0,"",IF(B22>2000,"Fail","Pass"))
You can do with the following 2 ways
=IF(ISBLANK(B22),"",IF(B22<2000,"Pass","Fail")) - Isblank used to check whether cell is empty or not.
=IF(B22="","",IF(B22<2000,"Pass","Fail")) - here nested If conditions used to check cell values

Display the value from the formula ONLY if another cell has the value that I want

I've devised a formula that I want my cells to have, but I only want the value to show up if ANOTHER cell is populated with the value that I want.
My current formula is below:
=COUNTIFS($R$3:R21, "Brain")
However, this formula doesn't check whether or not the other cell has the value that I want to check for.
I put together a formula that I thought would check for whether or not the cell is populated:
=COUNTIFS($R$3:R21, "Brain", R21, "Brain")
Unfortunately, this formula doesn't work (it returns #VALUE!). I think it fails because R21 is already included in the COUNTIFS.
I also tried this similar formula, which also failed to work:
=COUNTIFS($R$3:R21, "Brain", R21:R21, "Brain")
I looked online and I found this possible solution:
=IF(ISNUMBER(SEARCH("Brain",R21)),"COUNTIFS($R$3:R21, 'Brain')","")
Unfortunately, this formula displays the text of the formula I want, and not the actual value of the formula.
Does anyone know how I could display the value from the formula ONLY if the cell I'm checking has the value that I want? Thanks.
Try
=IF(ISNUMBER(SEARCH("Brain",R21)),COUNTIFS($R$3:R21, 'Brain'),"")

How can I use a formula with an IF function?

I'm wanting to check for blank cells, and when the cell is not blank, output a formula. However, I am getting errors and I believe you're not allowed to use formulas within an IF function, are you guys able to help me out?
=IF(A1="","",=lastModified(A1))
If the cell is not empty, this formula will return the date the cell was last modified. I do not want the date updated if the cell is blank.
Thanks for the help.
If you want to call the formula, just remove the equals sign. It will call when the FALSE condition triggers in your IF statement.
=IF(A1="","",lastModified(A1))

trying to expand vlookup to other cells without automatically changing values

I am setting up a vlookup to pull product prices from another sheet within the workbook. The code works for the cell but when i try to expand or copy and past the code into the next row it automatically changes the data table_array value.
=VLOOKUP(B5,Prices!1:65536,3)
Within the code i want the first value, B5 to scale with the row it is in, however the second value needs to remain the same. How do i go about doing this? Also is there a way that i can get the cell to remain blank instead of displaying N/A if there isnt a valid part number?
Thanks for your help!
=VLOOKUP(B5,Prices!$1:$65536,3)
The $ lock the range.
For example.
$A1 will lock the column to A when the formulas is copied other
locations.
A$1 will lock the row
$A$1 will lock both the column and the row.
I can't comment because I do not have enough rep but this will fix user3716271 's formula:
=IF(ISERROR(VLOOKUP(B5,Prices!$1:$65536,3)),"", VLOOKUP(B5,Prices!$1:$65536,3))
The following formula should solve both problems as well, a little more compact and would use one less VLOOKUP():
=IFERROR(VLOOKUP(B5,Prices!$1:$65536,3), "")
As guitarthrower had said, the $ before the number is used to lock the range.
For the second part, an IF formula will work fine:
=IF(ISERROR(VLOOKUP(B5,Prices!1:65536,3)),"",VLOOKUP(B5,Prices!1:65536,3)),"")
And if I understand correctly the first part have you tried set an absolute value? Something like:
=IF(ISERROR(VLOOKUP(B$5,Prices!1:65536,3)),"",VLOOKUP(B5,Prices!1:65536,3)),"")
