Excel function =isnumber(search *)) not working as expected - excel

When I running formula =ISNUMBER(SEARCH($B$2,$A3)), the output is true. Cell B2= "Red" and "Red" appears in cell A3. The condition is TRUE.
This formula fails when cell E2 is blank. There are no spaces or hidden characters.
Why is =ISNUMBER(SEARCH(E$2,$A3)) returning True?

You need to first check if E2 is blank and then proceed with ISNUMBER if true
=IF(ISBLANK(E$2), FALSE, ISNUMBER(SEARCH(E$2,$A3)))

SEARCH will interpret blanks as empty strings.
Another approach to what it looks like you're trying to do is to replace the substring with an empty string and see if the length changes:
=LEN($A2)>LEN(SUBSTITUTE($A2,E$1,""))

So, two variations, one as per the other answer but the other using find().
For the first, it returns a blank.
For the second with find() then iferror will deal with the value error.

Is it possible to use the "IsBlank()" function on a function's result?

I have created a function, where I would like to have a blank result in some cases, in order to use the IsBlank() function on it afterwards, but this seems not possible, as you can see from this example (the top row contains the used formulae):
As you see, the column "E" formula sometimes results in an empty string, but in Excel, an empty string is not blank (=IsBlank("") seems to yield FALSE).
Is there an Excel constant of function I can use as a "blank" result?
IsBlank tests if a cell is Empty. An empty string is != an empty cell. A regular formula cannot return Empty. So the answer to your Q is No.

Lookup and join text gives zero instead of blank

I am trying to lookup values based on two simple criterias.
Here is my formula:
{=TEXTJOIN(". ";TRUE;IF(F1=A2:A6;IF(F2=B2:B6;C2:C6;"");""))}
However, I get 0 in the middle of the text join. How can I ignore values in Text when it is actually empty or blank and get expected value of One. Two. Three. Five instead of One. Two. Three. 0. Five, where cell B5 is ignored and blank.
It's completely logical. It's just not as you intended it to work. Both IF conditions are TRUE and the next thing you tell the formula to return C2:C6 values. Therefore the IF returns a zero (you should use the evaluate formulas option to see what's going on), and therefore no longer an empty cell in a range, but a zero in an array. The TRUE parameter in the TEXTJOIN is therefor no longer helping you. To overcome this you could try:
=TEXTJOIN(". ",TRUE,IF((A2:A6=F1)*(B2:B6=F2)*(C2:C6<>""),C2:C6,""))
Note: It's an array formula and need to be confirmed through
CtrlShiftEnter
Try using array formula as below to get the desired result. Place the TEXTJOIN inside IF.
=IF(F1=A2:A6, IF(F2=B2:B6, TEXTJOIN(". ", TRUE, C2:C6), ""), "")

Excel formula to return value instead of TRUE or False

I am very newbie in excel, I wanted to make my formula to return matched value instead of TRUE/FALSE
=NOT(NOT(SUM(--NOT(ISERR(SEARCH($D$2:$D$21;$B2))))))
is there anyway this formula can be revised to return like for example: found word "wow" and return the word into the cell instead of TRUE/FALSE?
thank you
Use the =IF function.
=IF(condition; value if true; value if false)
condition is your condition to test. For example $A$1 < 5
value if true is a value returned if condition is true
value if false opposite to previous part, this is a value returned if condition is false.
Following formula will return a $A$1 cell value if less than 5 and too big literally if $A$1's value is bigger or equal to 5:
=IF($A$1<5; $A$1; "too big")
Just combine it with your condition.
You can use IF function:
=IF(logical_test, CONCAT("Found word", $YourWord), "Not found")
This will help You Remember the "Text" must be in " "
=IF(ISNUMBER(SEARCH(substring;"WOW")); "Yes"; "No")
The Value will be only Yes or No , You may change that
There are two cases and I'm not sure which one you need
(1) You have a word like WOW, and you want to find matches in a list of strings like BOWWOW
(2) You have a word like WOW, and you want to find matches for part of it in a list of substrings like OW
The easiest way to do the first one is to use MATCH with a wildcard
=INDEX($D$2:$D$21,MATCH("*"&B2&"*",$D$2:$D$21,0))
For the second one you would need to modify your formula a bit
=INDEX($D$2:$D$21,MATCH(0,(ISERROR(SEARCH($D$2:$D$21,$B$2))+($D$2:$D$21="")),0))
or
=INDEX($D$2:$D$21,MATCH(1,ISNUMBER(SEARCH($D$2:$D$21,$B$2))*($D$2:$D$21<>""),0))
the last two entered as array formulae using CtrlShiftEnter

IF statement: how to leave cell blank if condition is false ("" does not work)

I would like to write an IF statement, where the cell is left blank if the condition is FALSE.
Note that, if the following formula is entered in C1 (for which the condition is false) for example:
=IF(A1=1,B1,"")
and if C1 is tested for being blank or not using =ISBLANK(C1), this would return FALSE, even if C1 seems to be blank. This means that the =IF(A1=1,B1,"") formula does not technically leave the cells blank if the condition is not met.
Any thoughts as to a way of achieving that? Thanks,
Unfortunately, there is no formula way to result in a truly blank cell, "" is the best formulas can offer.
I dislike ISBLANK because it will not see cells that only have "" as blanks. Instead I prefer COUNTBLANK, which will count "" as blank, so basically =COUNTBLANK(C1)>0 means that C1 is blank or has "".
If you need to remove blank cells in a column, I would recommend filtering on the column for blanks, then selecting the resulting cells and pressing Del. After which you can remove the filter.
Try this instead
=IF(ISBLANK(C1),TRUE,(TRIM(C1)=""))
This will return true for cells that are either truly blank, or contain nothing but white space.
See this post for a few other options.
edit
To reflect the comments and what you ended up doing: Instead of evaluating to "" enter another value such as 'deleteme' and then search for 'deleteme' instead of blanks.
=IF(ISBLANK(C1),TRUE,(TRIM(C1)="deleteme"))
I wanted to add that there is another possibility - to use the function na().
e.g. =if(a2 = 5,"good",na());
This will fill the cell with #N/A and if you chart the column, the data won't be graphed. I know it isn't "blank" as such, but it's another possibility if you have blank strings in your data and "" is a valid option.
Also, count(a:a) will not count cells which have been set to n/a by doing this.
If you want to use a phenomenical (with a formula in it) blank cell to make an arithmetic/mathematical operation, all you have to do is use this formula:
=N(C1)
assuming C1 is a "blank" cell
You could try this.
=IF(A1=1,B1,TRIM(" "))
If you put this formula in cell C1, then you could test if this cell is blank in another cells
=ISBLANK(C1)
You should see TRUE. I've tried on Microsoft Excel 2013.
Hope this helps.
I've found this workaround seems to do the trick:
Modify your original formula:
=IF(A1=1,B1,"filler")
Then select the column, search and replace "filler" with nothing. The cells you want to be blank/empty are actually empty and if you test with "ISBLANK" it will return TRUE. Not the most elegant, but it's quick and it works.
The easiest solution is to use conditional formatting if the IF Statement comes back false to change the font of the results cell to whatever color background is. Yes, technically the cell isn't blank, but you won't be able to see it's contents.
This shall work (modification on above, workaround, not formula)
Modify your original formula:
=IF(A1=1,B1,"filler")
Put filter on spreadsheet, choose only "filler" in column B, highlight all the cells with "filler" in them, hit delete, remove filter
You can do something like this to show blank space:
=IF(AND((E2-D2)>0)=TRUE,E2-D2," ")
Inside if before first comma is condition then result and return value if true and last in value as blank if condition is false
The formula in C1
=IF(A1=1,B1,"")
is either giving an answer of "" (which isn't treated as blank) or the contents of B1.
If you want the formula in D1 to show TRUE if C1 is "" and FALSE if C1 has something else in then use the formula
=IF(C2="",TRUE,FALSE)
instead of ISBLANK
Here is what I do
=IF(OR(ISBLANK(AH38),AH38=""),"",IF(AI38=0,0,AH38/AI38))
Use the OR condition OR(ISBLANK(cell), cell="")
I think all you need to do is to set the value of NOT TRUE condition to make it show any error then you filter the errors with IFNA().
Here is what your formula should look like =ifna(IF(A1=1,B1,NA()))
Here is a sheet that returns blanks from if condition :
https://docs.google.com/spreadsheets/d/15kWd7oPWQmGgYD_PLz9YpIldwnKWoXPHtHQAT3ulqVc/edit?usp=sharing
Nope ... that only works for Googlesheets ... not Excel.
To Validate data in column A for Blanks
Step 1: Step 1: B1=isblank(A1)
Step 2: Drag the formula for the entire column say B1:B100; This returns Ture or False from B1 to B100 depending on the data in column A
Step 3: CTRL+A (Selct all), CTRL+C (Copy All) , CRTL+V (Paste all as values)
Step4: Ctrl+F ; Find and replace function Find "False", Replace "leave this blank field" ; Find and Replace ALL
There you go Dude!
Instead of using "", use 0. Then use conditional formating to color 0 to the backgrounds color, so that it appears blank.
Since blank cells and 0 will have the same behavior in most situations, this may solve the issue.
This should should work: =IF(A1=1, B1)
The 3rd argument stating the value of the cell if the condition is not met is optional.

=IF(ISERR(SEARCH query

I have a formula which is =IF(ISERR(SEARCH("M004",$H26)),NA(), "G26"). I have multiple words in cells 'H26' of which I am trying to find 'M004' but I want the formula once it identifies M004 to input the value in G26, not 'True, False.... etc' Is this possible???
For example, 'In 'I26', I want see if H26 contains the value M004, if so I want the cell to equal the value in G26
Possible?
Forgot to ask, what do I type so if 'false' to leave box blank?
If you want to leave the cell blank if N/A, do the following instead:
use ISERROR instead of ISERR: ISERROR will trap all error values, while ISERR will trap errors except #N/A
Change NA() to "" to get a blank cell in case of an error.
=IF(ISERROR(SEARCH("M004",H26)),"", G26)
I don't think getting FALSE is an option when you use SEARCH(), so you are covered for error cases when you use ISERROR().
Remove the quotation marks from around "G26" so that it is just G26
Also, here is an alternate formula that you can use:
=IF(COUNTIF(H26,"*M004*")>0,G26,NA())
