Excel пустая ячейка для формулы

Excel does not have any way to do this.

The result of a formula in a cell in Excel must be a number, text, logical (boolean) or error. There is no formula cell value type of «empty» or «blank».

One practice that I have seen followed is to use NA() and ISNA(), but that may or may not really solve your issue since there is a big differrence in the way NA() is treated by other functions (SUM(NA()) is #N/A while SUM(A1) is 0 if A1 is empty).

You’re going to have to use VBA, then. You’ll iterate over the cells in your range, test the condition, and delete the contents if they match.

Something like:

For Each cell in SomeRange
  If (cell.value = SomeTest) Then cell.ClearContents
Next

Yes, it is possible.

It is possible to have a formula returning a trueblank if a condition is met. It passes the test of the ISBLANK formula. The only inconvenience is that when the condition is met, the formula will evaporate, and you will have to retype it. You can design a formula immune to self-destruction by making it return the result to the adjacent cell. Yes, it is also possible.

All you need is to set up a named range, say GetTrueBlank, and you will be able to use the following pattern just like in your question:

=IF(A1 = "Hello world", GetTrueBlank, A1)

Step 1. Put this code in Module of VBA.

Function Delete_UDF(rng)
    ThisWorkbook.Application.Volatile
    rng.Value = ""
End Function

Step 2. In Sheet1 in A1 cell add named range GetTrueBlank with the following formula:

=EVALUATE("Delete_UDF("&CELL("address",Sheet1!A1)&")")

That’s it. There are no further steps. Just use self-annihilating formula. Put in the cell, say B2, the following formula:

=IF(A2=0,GetTrueBlank,A2)

The above formula in B2 will evaluate to trueblank, if you type 0 in A2.

You can download a demonstration file here.

In the example above, evaluating the formula to trueblank results in an empty cell. Checking the cell with ISBLANK formula results positively in TRUE. This is hara-kiri. The formula disappears from the cell when a condition is met. The goal is reached, although you probably might want the formula not to disappear.

You may modify the formula to return the result in the adjacent cell so that the formula will not kill itself. See how to get UDF result in the adjacent cell.

I have come across the examples of getting a trueblank as a formula result revealed by The FrankensTeam here:

Maybe this is cheating, but it works!

I also needed a table that is the source for a graph, and I didn’t want any blank or zero cells to produce a point on the graph. It is true that you need to set the graph property, select data, hidden and empty cells to «show empty cells as Gaps» (click the radio button). That’s the first step.

Then in the cells that may end up with a result that you don’t want plotted, put the formula in an IF statement with an NA() results such as =IF($A8>TODAY(),NA(), *formula to be plotted*)

This does give the required graph with no points when an invalid cell value occurs. Of course this leaves all cells with that invalid value to read #N/A, and that’s messy.

To clean this up, select the cell that may contain the invalid value, then select conditional formatting — new rule. Select ‘format only cells that contain’ and under the rule description select ‘errors’ from the drop down box. Then under format select font — colour — white (or whatever your background colour happens to be). Click the various buttons to get out and you should see that cells with invalid data look blank (they actually contain #N/A but white text on a white background looks blank.) Then the linked graph also does not display the invalid value points.

If the goal is to be able to display a cell as empty when it in fact has the value zero, then instead of using a formula that results in a blank or empty cell (since there’s no empty() function) instead,

• where you want a blank cell, return a 0 instead of "" and THEN

• set the number format for the cells like so, where you will have to come up with what you want for positive and negative numbers (the first two items separated by semi-colons). In my case, the numbers I had were 0, 1, 2… and I wanted 0 to show up empty. (I never did figure out what the text parameter was used for, but it seemed to be required).

  0;0;"";"text"@
  

This is how I did it for the dataset I was using. It seems convoluted and stupid, but it was the only alternative to learning how to use the VB solution mentioned above.

1. I did a «copy» of all the data, and pasted the data as «values».
2. Then I highlighted the pasted data and did a «replace» (Ctrl—H) the empty cells with some letter, I chose q since it wasn’t anywhere on my data sheet.
3. Finally, I did another «replace», and replaced q with nothing.

This three step process turned all of the «empty» cells into «blank» cells». I tried merging steps 2 & 3 by simply replacing the blank cell with a blank cell, but that didn’t work—I had to replace the blank cell with some kind of actual text, then replace that text with a blank cell.

Use COUNTBLANK(B1)>0 instead of ISBLANK(B1) inside your IF statement.

Unlike ISBLANK(), COUNTBLANK() considers "" as empty and returns 1.

Wow, an amazing number of people misread the question. It’s easy to make a cell look empty. The problem is that if you need the cell to be empty, Excel formulas can’t return «no value» but can only return a value. Returning a zero, a space, or even «» is a value.

So you have to return a «magic value» and then replace it with no value using search and replace, or using a VBA script. While you could use a space or «», my advice would be to use an obvious value, such as «NODATE» or «NONUMBER» or «XXXXX» so that you can easily see where it occurs — it’s pretty hard to find «» in a spreadsheet.

So many answers that return a value that LOOKS empty but is not actually an empty as cell as requested…

As requested, if you actually want a formula that returns an empty cell. It IS possible through VBA. So, here is the code to do just exactly that. Start by writing a formula to return the #N/A error wherever you want the cells to be empty. Then my solution automatically clears all the cells which contain that #N/A error. Of course you can modify the code to automatically delete the contents of cells based on anything you like.

Open the «visual basic viewer» (Alt + F11)
Find the workbook of interest in the project explorer and double click it (or right click and select view code). This will open the «view code» window. Select «Workbook» in the (General) dropdown menu and «SheetCalculate» in the (Declarations) dropdown menu.

Paste the following code (based on the answer by J.T. Grimes) inside the Workbook_SheetCalculate function

    For Each cell In Sh.UsedRange.Cells
        If IsError(cell.Value) Then
            If (cell.Value = CVErr(xlErrNA)) Then cell.ClearContents
        End If
    Next

Save your file as a macro enabled workbook

NB: This process is like a scalpel. It will remove the entire contents of any cells that evaluate to the #N/A error so be aware. They will go and you cant get them back without reentering the formula they used to contain.

NB2: Obviously you need to enable macros when you open the file else it won’t work and #N/A errors will remain undeleted

What I used was a small hack.
I used T(1), which returned an empty cell.
T is a function in excel that returns its argument if its a string and an empty cell otherwise. So, what you can do is:

=IF(condition,T(1),value)

I used the following work around to make my excel looks cleaner:

When you make any calculations the «» will give you error so you want to treat it as a number so I used a nested if statement to return 0 istead of «», and then if the result is 0 this equation will return «»

=IF((IF(A5="",0,A5)+IF(B5="",0,B5)) = 0, "",(IF(A5="",0,A5)+IF(B5="",0,B5)))

This way the excel sheet will look clean…

Well so far this is the best I could come up with.

It uses the ISBLANK function to check if the cell is truly empty within an IF statement.
If there is anything in the cell, A1 in this example, even a SPACE character, then the cell is not EMPTY and the calculation will result.
This will keep the calculation errors from showing until you have numbers to work with.

If the cell is EMPTY then the calculation cell will not display the errors from the calculation.If the cell is NOT EMPTY then the calculation results will be displayed.
This will throw an error if your data is bad, the dreaded #DIV/0!

=IF(ISBLANK(A1)," ",STDEV(B5:B14))

Change the cell references and formula as you need to.
