I am using the following formulae for a truly unique ranking of values: How to Rank Duplicate Values Sequentially.
(As you may or may not be aware the other option (see ##) can produce erroneous results!)
However, there is a problem: I would like to ignore empty cells! Currently, empty cells are counted as having the value zero.
How do I need to change the formulae in 1 to ignore empty cells and to return no value at all? Is that even possible with an array formula?
I avoid VBA as I need to keep this dynamic.
Thank you in advance for any hints!
pascal
(##): =RANK(A2,$A$2:$A$10)+COUNTIF($A$2:A2,A2)-1
End result:
Method (A1 is top left):
Data2: =IF(ISBLANK($A2),"",VALUE($A2&"."&(ROW()-ROW($B$1))))
Sorted: =SMALL($B$2:$B$8,ROW()-ROW($C$1))
Rank: =IFERROR(MATCH($B2,$C$2:$C$8,0),"")
I think this formula should work OK, to create "unique ranks" and return blanks for blanks
=IF(A2="","",RANK(A2,$A$2:$A$10)+COUNTIF($A$2:A2,A2)-1)
I'd expect that to calculate correctly assuming A2:A10 contains numbers (not text formatted) and where the numbers don't exceed 15 significant digits....but if you want to avoid COUNTIF then this formula with SUMPRODUCT should do the same:
=IF(A2="","",SUMPRODUCT((A$2:A$10>A2)*(A$2:A$10<>""))+SUMPRODUCT((A$2:A2=A2)*1))

We use this format in our casino to know where we have to send our employees to certain tables or games. We recently changed the way we do this and we now need to have some checks to make sure we didn't forget certain tables.
Every hour/half hour/20mins we assign a table to a person, everyone else moves one up. We know exactly which tables are open at which times. We fill this in at the top. When we fill in the upcoming timeslot we would like to have some check so we don't forget a table and maybe miss out a employee.
Example:
In the example supplied you can see that we accidentally have two number 6's but no 7 I highlighted the number 7 in the top row but it would be nice if this is doable automatically
I used VLOOKUP and INDEX/MATCH in the formula for Conditional formatting but that does not seem to create the correct outcome.
Here is an example of how it can be done:
The formula used has the array {1;2;3;4;5;6;7} hard written into it, assuming that the number of tables does not vary. The output is 0 when no table is missing, otherwise it returns a list of missing tables separated by commas.
Note: That of course means, the comma separated list is not a numeric value but a string value and cannot be used for further calculations. If further calculations on this output are required, the 'solution' has to be changed accordingly.
Formula
=IFERROR(CONCAT(FILTER({1;2;3;4;5;6;7},ISERROR(MATCH({1;2;3;4;5;6;7},H5:H24,0)))&", "),0)
Explanation
The MATCH() function checks which of the numbers 1 to 7 are present in the given range (here H5:H24) and returns the cell index of where it is found. When a number does not appear in the range, the MATCH() function will generate an #N/A error for that number.
Then, the ISERROR() function will output a FALSE value for all numbers found by MATCH() and a TRUE value for those numbers where the MATCH() function lead to an error.
The FILTER() function filters and thereby reduces the number array {1;2;3;4;5;6;7} to only those numbers where the ISERROR() function is TRUE.
The CONCAT() function concatenates the resulting array from the FILTER() function (in case more than 1 number is missing) to a single string of numbers separated by commas.
However, when there are no open tables, i.e. the MATCH() function finds all numbers 1 to 7 in the given range, then the ISERROR() function will only return FALSE values and the thus the FILTER() function returns an 'empty' array, which is not allowed in excel and leads to an #CALC error in excel. This case is captured by the IFERROR() function encapsulating the whole calculation, and instead of showing the error, returning 0.
What about this formula:
=AND(COUNTIF(A$2:A$10,1)=1,COUNTIF(A$2:A$10,2)=1,COUNTIF(A$2:A$10,3)=1,COUNTIF(A$2:A$10,4)=1,COUNTIF(A$2:A$10,5)=1,COUNTIF(A$2:A$10,6)=1,COUNTIF(A$2:A$10,7)=1)
A bit clearer:
=AND(COUNTIF(A$2:A$10,1)=1,
COUNTIF(A$2:A$10,2)=1,
COUNTIF(A$2:A$10,3)=1,
COUNTIF(A$2:A$10,4)=1,
COUNTIF(A$2:A$10,5)=1,
COUNTIF(A$2:A$10,6)=1,
COUNTIF(A$2:A$10,7)=1)
... which means that the number of ones need to be 1, the number of twos need to be 1, ..., up to the number of sevens.
Hereby a screenshot of an Excel sheet, which contains that formula:
In order to understand how this works, you might work with formula auditing, more especially formula evaluating, hereby an extra screenshot, showing formula evaluating after some steps:

What I'm attempting to do is count the number of blank cells across a dataset where the header of the row matches an array.
=countifs(D1:AZ,D2:AZ,D1:1,A2)
However, it appears that since the array sizes are different, it can't use it as a lookup.
Ideally, I'd be able to get an array formula to count the number of non-blank cells that correspond to each date in A2:A, like this:
Looking at the documentation for COUNTIFS, I don't see anything about it not being able to handle vertical and horizontal matching.
Also, I need to avoid using =query(), since there may be instances in D1:1 where a date is missing. I will be handling that with an iferror().
Any help/advice you all could provide would be greatly appreciated!
I have made an editable copy of the dataset here for reference.
Thanks
Try this. It is a matrix multiplication formula that sums up the nonblank cells for each column. It should work for you.
=arrayformula(mmult(transpose(if(D1:1="",0,if(isblank(D2:BG),0,1))),sign(ROW(D2:BG))))
I can explain it if you are interested.
EDIT: How about this? It adds a vlookup.
=arrayformula(iferror(vlookup(A2:A,{transpose(D1:1),mmult(transpose(if(D1:1="",0,if(isblank(D2:BF),0,1))),sign(ROW(D2:BF)))},2,false)))
This may be a way to do it, on B2:
=COUNTIFS(OFFSET($D$2:$D,,MATCH(A2,$D$1:$AZ$1,0)-1),">0")
Then you auto fill down, the idea is:
MATCH(A2,$D$1:$AZ$1,0) Will match each date on column A to the date on row 1 and return an index (from 1 to N).
OFFSET($D$2:$D,,N) Will take the range D2:D and offset N columns (In this case the output of MATCH).
Finally COUNTIFS will look for >0 values in the column which header matches the date on the left.
I hope it helps
This is what I am trying to figure out:
IF date in cell matches dates in range
and
If name in cell matches names in range
then
count/sum the number of unique ID#s
This is the formula I have:
=IF(Data!A:A=E10,(IF(Data!D:D=D11,(IF(Data!D:D=D11,SUM(IF(FREQUENCY(Data!C:C,Data!C:C)>0,1)),"ERROR3")),"ERROR2")),"ERROR1")
It does not output the correct info. It either counts all the unique IDs or it Errors out when it should have a result.
I hope I am on the right track, thank you for any help.
Sample dataset:
Try it as,
=SUMPRODUCT(SIGN((B$2:B$10>=E2)*(B$2:B$10<=F2))/
(COUNTIFS(B$2:B$10, ">="&E2, B$2:B$10, "<="&F2, A$2:A$10, A$2:A$10)+(B$2:B$10<E2)+(B$2:B$10>F2)))
First let me say that the question was pretty confusing before you posted an image of the data, as it appears that the term "dates in range" was completely misleading. In fact you are trying to match exact dates, not "ranges of date".
FREQUENCY is useful to detect the first appearance of an item in a column, but unfortunately, this "artificial trick" is not flexible enough to be mixed easily with other criteria, and most importantly FREQUENCY is not array friendly.
There's another method to achieve you goal, which is:
=SUMPRODUCT(((Data!$A$1:$A$24=E$10)*Data!$C$1:$C$24=$D11))/
COUNTIFS(Data!$A$1:$A$24,Data!$A$1:$A$24,Data!$B$1:$B$24,Data!$B$1:$B$24,Data!$C$1:$C$24,Data!$C$1:$C$24))
You can enter this formula in E11 in your sample image and copy/paste in the whole matrix.
The denominator of the formula (the second line) generates an array that counts for each row the number of duplicates.
The numerator sets the criteria. Since each successful row will repeat as many times in the numerator and in the denominator, each matching row will be counted for a total of one.
As a result, we obtain the number of "unique rows" that match the criteria.
The formula should not use complete columns such as A:A etc, make the effort to limit it to a reasonable number of rows, say A1:A999 or so. Complex formulas involving arrays must avoid as much as possible entire columns.
I am trying to use a COUNTIFS formula to calculate how many installs are done. This is done by searching through a large table containing many blank cells. When using the following formula, I receive a #VALUE! error because Excel sees the blank cells as 0s and gets confused trying to count strings and integers:
=COUNTIFS(B10:B152,"Installs",D10:N152,"Done")
The range D10:N152 contains blanks and is causing the error.
Can I make Excel ignore those blanks or see them as strings instead of integers?
For COUNTIFS:
Important Each additional range must have the same number of rows and columns as the criteria_range1 argument. The ranges do not have to be adjacent to each other.
Maybe add a helper column, say O with:
=IF(MATCH("Done",D10:N10,0)>=1,"Done","")
copied down to suit and then:
=COUNTIFS(B10:B152,"Installs",O10:O152,"Done")
Now we know only one Done per row (and assuming Done is on its own in a cell) then a helper column with say:
=COUNTIF(D10:N10,"Done")
would be a shorter formula than =IF(MATCH("Done",D10:N10,0)>=1,"Done","") and also allow a shorter formula than =COUNTIFS(B10:B152,"Installs",O10:O152,"Done") for the counting, say:
=SUM(O:O)
instead (assuming the rest of ColumnO is blank or text, otherwise =SUM(O10:O152).
However I aimed for a formula as similar as possible to that used by OP, for which the helper column needed to be populated with Done also. At the time I was allowing for the possibility there might be more than one Done per row.
As pointed out in a comment, the helper column might have been populated with fewer keystrokes than =IF(MATCH("Done",D10:N10,0)>=1,"Done",""), if only by excluding the result for failure of the test, say =IF(MATCH("Done",D10:N10,0)>=1,"Done") since MATCH never ‘fails’ – rather it returns #N/A where no match is found, which is good enough for a COUNTIF function since that does not count #N/As when the criterion is Done.
Try this FormulaArray:
=SUM(($B$10:$B$152="Installs")*($D$10:$N$152="Done"))
I'm having an excel column range (including blank cells) something like:
00EGB00-GE001
00EGB00-GE001
00EGB00-GE001
00EGB00-GE001
00EGB00-GE002
00EGB00-GE002
00EGB00-GE002
00EGB00-GE002
00EGD20-GD101
What I need is to Count total number of similar values and I'm stuck with the logic for counting total unique "similar" values... example "GE" & "GD" separately.
How to count total number of unique "GE" values in the list?
I thought =COUNTIF(B:B,"*GE*") should work but it does not. It gives total count of "GE" but I need to find unique count. Example GE001 & GE002 should be considered as 2 values in total.
Kindly help
EDIT AGAIN: Given further clarification below, and assuming that the data always has the same number of digits, one way to do it is by putting this in Column B:
=RIGHT(A1,5)
Then, if you have Excel 2007 or up, Copy and Paste Values and use Remove Duplicates to leave you with the unique values. Then remove the items with GD, either manually or using a formula.
In this case, the output is:
GE001
GE002
In this case, you can easily see that it's 2. If you have lots of values, you can use COUNTA. Is that what you want?
YET ANOTHER EDIT BASED ON LAST COMMENT: this is probably getting closer:
=SUMPRODUCT(--(MID(A1:A9,9,2)="GE"),1/COUNTIF(A1:A9,A1:A9))
Where the "GE" is hard-coded in the formula above you could also substitute a cell reference where you can alter the value.
Or, if you don't know where the text you want will be exactly because the number of characters change, this will work (but you'd need to be careful with what you were searching on because it might repeat somewhere else in the string):
=SUMPRODUCT(--(ISERR(SEARCH("GE",A1:A9))<>TRUE),1/COUNTIF(A1:A9,A1:A9))
Again, you can replace the "GE" with a cell reference.
As discovered below, though -- blank cells will cause this to fail. There IS almost definitely a way to cater for them (maybe using a FREQUENCY based Array Formula), but if you can live with cleaning out the blank cells then that would be one way of doing it.
LAST EDIT: this will account for blank cells. It is an Array Formula, and CAN be used on whole columns, but that will be quite slow as it takes up a fair bit of calculation effort:
{=SUMPRODUCT(--(MID(A1:A9,9,2)="GE"),IF(ISBLANK(A1:A9),1,1/COUNTIF(A1:A9,A1:A9)))}
As it's an Array Formula, use Ctrl + Shift + Enter to input it.
