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.

Very interesting article, I had the following problem which shows how important it is to have a understanding about blank and empty cells but also how excel is dealing with it:

I wanted to calculate a weighted result with the following formula, I always have arrays but there is one example where it is just one cell.

In this example the column K has the weights for calculation while L has the numeric OR NV values.

if L68 is #NV I get a completely wrong result when I use the following formula:

=SUMPRODUCT(K68,IFERROR(L68;""))/SUMPRODUCT(K68)

it returns 0, but 0 in my case is fatal as I am calculating a rating which has a range from -1 to +1 and 0 would be a rating which would lead to a wrong aggregation on a top level.

the correct way would be to leave the argument out as you showed in your example:

=SUMPRODUCT(K68,IFERROR(L68;))/SUMPRODUCT(K68)

this returns an ERROR which I could convert to NV and the SUMPRODUCT handels it as if L68 would be an empty cell, although it isn't empty as ISEMPTY(IFERROR(L68;)) would be FALSE.

this is really confusing, sometimes frustrating.

I currently have an IF formula in the cell next to it to only show a value if the formula in question has displayed a figure. However, the IF Formula thinks that the actual formula is classed as a cell with content.

Is there a way of making this cell 'blank' or a way of making the IF Formula work?

I am not sure how to keep a formula going when at the end of my column so that it doesn't keep pasting the same number until data is entered.

My formula is: F9=D10-E10 It is repeated for the 11 rows I have entered data; however, if I pull the formula to down to continue to row 25, the number on row 11 (column F)is just shown repeatedly til row 25

Can't I have the formula there but not show the data until it is entered. Column F is where the data is totaled.

This one does not work:

IF(OR(D10="",E10=""),"",D10-E10)

I have formulated cells on column A.

Some are % values some are blank ("") as a result of the formula.

Column B cells rank according to couln A values.

But, I jus want to have a ranking f the cells where there is a%. Instead it is ranking the total.

In other words if 3 out of 10 cells on column A are blank I want the ranking amongst the other 7.

Use a "IF" statement. If cell(workbook cell) = "", "", cell(workbook cell)

That means if the cell equals blank, return blank, if not return cell value

I need to fix it so that if the cell it is pulling info from is blank, then the cell on the all in compassing worksheet is also blank. Instead it returns a 0. When I use this all in compassing worksheet to make address labels then it leaves a 0 on the label. Help!!!!

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.

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)

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!

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

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.

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.

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.

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.
