The purpose of formulas is to return a value based upon a calculation or comparison. For instance, if you use the formula =1+1, the sum is calculated and the value 2 is returned. There might be times, however, when you want to use a formula and actually return nothing. For instance, you might want to compare a value in a cell to some constant and return a numeric value if they are equal or return nothing if they are different.

The problem is that a formula must, under all circumstances, return something—for it not to do so would go against the very purpose of formulas. There are two ways to approach the problem, and how you do so will affect what you can and cannot do with your results. Consider the following formula:

=IF(A1=0,"",1)

In this instance, the cell containing this will contain a blank value ("") if A1 is 0 or it will contain a numeric value (1) if it is not 0. In either case, something is being returned. You could, however, use the following variation on the formula:

=IF(A1=0,,1)

The only difference here, of course, is that the quote marks have been removed. Interestingly enough, in this case Excel assumes there is a zero between the two consecutive commas, and if A1 is 0, the formula returns a 0. Again, formulas must return something.

The way that Excel's other functions interpret the results of these two formulas is also very interesting. It is instructive to look at how the COUNT, COUNTA, and COUNTBLANK functions interpret the results.

COUNT is used to count the number of cells in a range that contain numeric values. If the cells contain text, or if they are empty, they are ignored. In the case of our formulas, if you use the first formula, COUNT counts the cell if A1 is not zero. If you use the second formula, COUNT will always count the result, since it always returns either 0 or 1, which are both numeric.

COUNTA is used to count the number of cells in a range that contain anything. Regardless of which formula you use, COUNTA will count the cell since formulas always return something. (It can also be argued that COUNTA counts the cell because it contains a formula, but that is probably a fine semantic difference.)

COUNTBLANK examines cells and counts them only if they are blank. In the case of the first formula, COUNTBLANK will count the cell only if A1 is 0. In the case of the second formula, COUNTBLANK will never count the cell, since the formula always returns a 0 or 1 and is therefore never blank.

The above discussion applies if the COUNT, COUNTA, or COUNTBLANK functions are evaluating the results of a series of cells that actually contain formulas. However, if the range includes cells that are really blank (i.e., they contain nothing, not even a formula), then that can affect what is returned by the functions. Blank cells don't affect the results returned by either COUNT or COUNTA, but they do affect the results returned by COUNTBLANK.

What does all this mean? It means that a cell that contains a formula is never really, truly blank—only cells with nothing in them are blank. How the result of the formula is interpreted, however, depends on the Excel functions being used to perform the interpretation. Since different functions interpret formula results differently, you need to be concerned with what you really want to find out about the formula results, and then use the function that will help you best determine that information. If you don't get the result you expect with a particular function, search around—chances are good that Excel has a different function you can use to get the desired results.

That being said, if you have a range of cells that all contain formulas similar to =IF(A1=0,"",1), and you want to delete the formulas in the cells that return a blank value (""), you can quickly do so by following these steps:

- Select the range containing the formulas in question.
- Press
**F5**. Excel displays the Go To dialog box. (See Figure 1.) - Click Special. Excel displays the Go To Special dialog box. (See Figure 2.)
- Make sure the Formulas radio button is selected.
- The only check box that should be selected under Formulas is Text.
- Click OK. Excel selects all cells where the formula returned a text value. (This should be all the formulas that returned "".)
- Press Delete.

Ok. I hope I am wording this right.

I have a workbook set up where I enter data into the first sheet and the sheets after all have their own functions and auto populate data entered from sheet 1. I.E. Serial numbers change but other information is static so the other sheets auto populate the serial numbers. These serial numbers are made up from 3 cells, a "Prefix", the number (which is the changing data) and a "Suffix". My dillema is that I'm combining the values of the three cells, twice, into one cell value to show "ABC123X and ABC124X". Here's how the formula looks now.

"='INPUT INFO HERE'!G1&'INPUT INFO HERE'!C3&'INPUT INFO HERE'!G2&" and "&'INPUT INFO HERE'!G1&'INPUT INFO HERE'!C4&'INPUT INFO HERE'!G2"

What I need is an "IF='INPUT INFO HERE'!C4=0,""," function inserted so that if the C4 cell has no value, then the cell will only show the value of the one half like so "ABC123X" and not "ABC123X and" or "ABC123X (and the rest of the bad formula"

Any ideas? I'm going to write this once and then cope the cells over and over, inserting the $ before the static values like $G$1 and $G$2.

Hi Everyone can someone correct this formula

E26 cell contain = Sunday

G26 cell contain = Blank

Another

G26 cell contain = 9:26

IF(and(E26<>ISBLANK(G26),"Absent",E26<>isnumber(G26),"Working")))

E26 cell contain = Sunday

G26 cell contain = Blank

Another

G26 cell contain = 9:26

IF(and(E26<>ISBLANK(G26),"Absent",E26<>isnumber(G26),"Working")))

Need help. Need to create a formula if and sum

I have 3 different columns need to get the total based on Yes Or No condition

If A=Yes value is $250 if A=No Value is $0

Then If B=Yes value is $300 if B =No value is $0

Total column should be based on answer Yes or NO

I need some help with creating a formula. I'm creating a call center monitoring form and 1.) I need all cells add up to 100%. 2.) I need my cells to equal 5 points.

If you are wanting a blank cell returned for visual purposes and not necessarily a trully blank value in the cell you can let the standard formula return a 0 in the cell and then conditionally format the cell to change the color of the text to match the fill background of the cell color when there is a 0 in the cell. This will make it look blank for visual evaluation purposes.

@Danny,

For earlier versions than "Excel 2007" try:

=IF(ISERR(A1/A2),"",A1/A2)

For Newer versions try:

=IFERROR(A1/A2,"")

This formula will do as you ask but will display 0 if A1 is 0

=IF(OR(A1="",A2=0),"",A1/A2)

if you want the result to be blank if A1 is 0 then use this formula:

=IF(OR(A1=0,A2=0),"",A1/A2)

This formula will do as you ask but will display 0 if A1 is 0

=IF(OR(A1="",A2=0),"",A1/A2)

if you want the result to be blank if A1 is 0 then use this formula:

=IF(OR(A1=0,A2=0),"",A1/A2)

Hello,

This is my formula.

=(SUM(L13+P13)-(L12+P12))*24.

I would like to return a 0 if there are not values in the targeted cells. Thank you for your help.

Hi,

I'm trying to use this IF formula.

What i'm trying to say is that if a cell is empty do not have comma, if there is text in it start with "," and then the text after that.

I use the If formula in a CONCATENATE fomula.

Really appriciate your help!

great tip. thanks for sharing

how do I hide and display the end product of rank formula i.e in the result cell it will indicate 1.

Hi im am really hitting a wall

I have a simple formula that calculates the ratio (=a2/a1). however I would love for it to be blank if there is an error. E.g. if there is nothing in a1 or a2, I would like the cell the be blank and not (#Dive/0!)

Any advice? :)

Thanks

Hi,

I wonder if anyone can help me with this "blank" cells isuue that I am having. I used "find and replace" to replace cells containing only "X" with blank. After replacing, although the cell is blank, when I view formula bar, it has a " ' " in each cell. As such when I use isblank()to check on each of those cells, it is indictaed as false.

How can I use "find and replace" to truly replace the cell with a blank?

Thanks.

@ Laine

This can be solved using an IF function.

Change your formula to: =IF(D9="","",E8+D9)

@ Adrian

The solution is similar to Laine's but requires both cells to be blank (or have a zero length string) for the results cell (the one with the formula in it) to be blank.

Change the formula to: =IF(AND(F5="",G5=""),"",(F5+G5)/2)

Technically the tested cells (D9, F5 or G5) do not need to be blank they could have a formula that results in a blank or a zero length string.

if I have 2 cells that are empty F5 and G5 how can I leave the cell with the formula in blank =(F5+G5)/2

This is driving me mad but I suspect it is a simple fix. EG. Cell D8=22.00. D9 is blank. E8=22.00. Formula in E9 is E8+D9. But if D9 is blank, I don't want the formula to display after I copy the formula down the page.

There are two problems with COUNTA - firstly, the Excel documentation says it counts non-blank cells. However, the definition of 'blank' here is different than the definition used by ISBLANK or COUNTBLANK, both of which treat "" as blank. So you get the unexpected result that COUNT(range) may or may not = COUNTA(range) + COUNTBLANK(range).

Secondly, in terms of the various solutions which involves locating 'blank' cells and clearing them in order that COUNTA will give the desired answer, these are not helpful when the 'blank' result is the result of a formula, since this will then clear the formula from the cell.

Hi there,

In my specific situation, I am using a combo-box to filter data based on the value selected from the drop down. The problem I'm running into is that without being able to return a blank cell into the advanced filter criteria I am not able to undo the filter when selecting the blank cell in the dropdown menu. I'd like to be able to use the combobox to choose numbers 1-3 or to undo the sort. Any suggestions?

This is what my VBA looks like for the combo box so far...something is not working. I added the last bit in an effort to clear the cell, but that doesn't seem correct though it doesn't return an error:

Private Sub ComboBox1_Change()

'runs advanced filter based on combobox value'

Range("C31:DM98").AdvancedFilter Action:=xlFilterInPlace, CriteriaRange:= _

Range("C4:DN5"), Unique:=False

ActiveWindow.SmallScroll ToRight:=-86

'specifies if value is zero to clear filter'

For Each cell In [ComboBox1]

If (cell.Value = 0) Then cell.ClearContents

Next

End Sub

THANK YOU IN ADVANCE!!!! No one seems to know the answer.

In the case I just mentioned, you can instead return NA() for the formula and then search for Error only. This should work great for me. Thanks for the idea to use Go T

I like the idea, unfortunately it only works if your formula will only return numeric values. If your formula can return a numeric or text value, this will also highlight any valid text you want to keep.

thomas - you are a genious... no one else could help

I use a method where i intentionally create an error value as

=IF(A1=0,22/0,1)

and then with Goto, Special, formulas,errors box checked, I erase the cells containing the error value.

=IF(A1=0,22/0,1)

and then with Goto, Special, formulas,errors box checked, I erase the cells containing the error value.

I have this formula: =IF(COUNTIF(H2:X2:AB2:AJ2:AM2:AO2:AR2:AZ2:BD2:BP2:BU2:CQ2:CU2:DW2,"Y")=COUNTA(H2:X2:AB2:AJ2:AM2:AO2:AR2:AZ2:BD2:BP2:BU2:CQ2:CU2:DW2),"Y","N") The box this is in returns either a Y or an N depending on the selection in the cells, however it does no return a blank if all the ranged cells are blank.This needs to return a blank only when all cells in those ranges are blank. If even one of the cells has an entry I need it to return that value. Can you help?
