This question can, I guess, be part of the same problem mentioned in another question that I have asked a couple of days ago.
My problem is that I have an array formula that looks in a table for cells containing FAIL. Basically, if there is a FAIL in the table, the array formula returns the line of the fail if there is none it says No failure.
But I also have buttons running some macros that filter the data in the same table (but do not remove the FAIL). When I click on the button/run the macro the macro display No failure which is not correct. However if I press ctrl+shift+enter (without changing the formula) it updates to the correct value (being the line of the FAIL).
So in a nutshell my array formula is not updating until I press ctrl+shift+enter a second time and i don't know why.
Refreshing the sheet, closing-opening again, or using the calculate now function do not work.
My formula (fairly messy I admit haha) is:
=IF(TEXTJOIN(",",TRUE,IF((Table1[Load Pass fail]="FAIL"),IF(NOT(ISBLANK(Table1[Measure])),ROW(Table1[Load Pass fail]),""),""))="",IF($E$23="","Not run","No failure"),TEXTJOIN(",",TRUE,IF((Table1[Load Pass fail]="FAIL")*(NOT(ISBLANK(Table1[Measure]))),ROW(Table1[Load Pass fail]),"")))
If you can help me thank you in advance.
EDIT: it appears that when I change one of the value in the parts of the table targeted by my array formula it triggers the formula and it goes back to the correct value.

I have a python 3.7 script that has been developed using the OPENPYXL (v2.5.10) library to take data from a number of excel workbooks, to process that data and then to write to a separate excel workbook. The results workbook contains around 100 named ranges and numerous formula which all work as expected including automatically calculating when the workbook is opened in excel.
I am having trouble with one particular formula group which includes the AGGREGATE function. In this case the formula writes to the results workbook, to the correct cell and in the correct form. While other formulas show the resulting value on opening the workbook, this sequence of formulas only show a result if you select the cell, place the cursor in the formula bar (as if you are editing the formula) and then you push the enter/return key. No change or edit is made to the formula. Once you have done this the formula works as expected.
I have tested this on both the latest macOS and windows versions of excel and I get the same behaviour. I should add that trying the 'calculate now', CtrlShiftAltF9, and 'calculate sheet' options do not have any impact. The only time the formula calculates is if you use the enter/return key.
The code that writes the formula is:
activeSheet.cell(row, col).value = f"=IFERROR(INDEX({rngData}, AGGREGATE(15,3,({rng}={cellRef})/({rng}={cellRef})*ROW({rng}),{nth}),{colIndex}),\"\")"
which gives, for example, a correct result in the excel workbook cell as:
=IFERROR(INDEX(_monthAgedDebt_Data, AGGREGATE(15,3,(_monthAgedDebt_ProjectNumbers=$L$4)/(_monthAgedDebt_ProjectNumbers=$L$4)*ROW(_monthAgedDebt_ProjectNumbers),1),6),"")
So in summary:
the code works as it writes the correct formula to the correct cell and in the correct form
in excel the formula does not automatically calculate but only works if you edit the formula in the cell, make no changes, and push enter/return to exit the edit
Is it an issue with AGGREGATE producing an array result? I chose this form of formula principally because you do not need a CTL-SHIFT-ENTER to make it work. If you enter it directly into a cell in excel you can enter it as a normal formula.
I haven't been able to find help on stack overflow other than this one. However, the solution proposed here doesn't work either.
This question poses a similar issue but has no relevant responses.
This question may hold a clue but I don't seem to be able to make that work as well.
Any thoughts on how to fix this issue appreciated. I am not sure if it is an openpyxl issue or an excel issue and am not sure what else to test.
All - the final answer for completeness.
It turns out that the key to solving this issue lay with OPENPYXL and that the guidance provided in the answer by Charlie Clark to this
question
was correct. I had initially applied the solution incorrectly.
I changed the formula to:
activeSheet.cell(row, col).value = \
f"=IFERROR(INDEX({rngData}, _xlfn.AGGREGATE(15,3,({rng}={cellRef})/({rng}={cellRef})*ROW({rng}),{nth}),{colIndex}),\"\")"
by adding in the '_xlfn.' to the front of the AGGREGATE function statement.
The excel spreadsheet now works as expected without the need to edit the cell containing the formula.
I've been struggling with this longer than I care to admit, but I have a fairly simple OFFSET function call which works on one sheet, but if I copy it to a different sheet it gives a #VALUE error.
On a sheet named "Deliverable" I have this formula in a cell:
=OFFSET(Deliverable!$B$72,1,0,,3)
and it works fine.
If I go to any other sheet and use the same exact formula, or use it in the Name Manager, it gives a #VALUE error.
If I leave off the final parameter indicated the number of columns I want, it does work:
=OFFSET(Deliverable!$B$72,1,0)
but of course isn't giving me the range I need.
Any idea what's going on with this?
I'm using Excel 2016 on Windows 7.
-- Updated Info --
In a nutshell, my spreadsheet has two cells which I'm using as dropdown lists, where the 2nd cell's list feeds off the selection in the first. The data they are based on has this format:
OptionA A B C D
OptionB A B
OptionC D E F
So the first dropdown uses a simple Data Validation source pointing to the column with OptionA, OptionB, etc. Once that's chosen, the second dropdown list should contain the appropriate options for the one selected. So if OptionB is selected, then the 2nd dropdown list should show A and B.
When I initially wrote this, the data validation source was just a simple VLOOKUP entry, but the lists often had blanks since the number of options varies for each entry. Wanting to fix it up a bit, I ended up with this formula:
=OFFSET(Deliverable!B72,Deliverable!B87,0,1,COUNTA(OFFSET(Deliverable!B72,Deliverable!B87,0,1,5)))
There won't be any more than 5 options, and there are no empty cells in the middle of the data to filter out.
In one spreadsheet I have I used this as a named range definition, then specified the named range for the cells data validation source and it worked. In this other spreadsheet however, it gave me the error described earlier.
However, it looks like when I enter the statement directly into the data validation source field and not in the name manager, it works as expected.
Am I taking the totally wrong approach?
What is it that you want this formula to do? As written, it is returning a block of three horizontal cells. The #VALUE error is Excel's way of telling you "Hey, you're trying to return three cells, but I can't fit them all in the one cell that you are calling this formula from".
The reason you see a result in some places and not others is because of something called Implicit Intersection. Give it a spin on Google. But basically, it just returns whichever one of those three results corresponds to the column that the formula is entered into. If you copy that exact same formula to say row F you will see that it returns a #VALUE error there, because it doesn't know what cell it should return given the column you're calling it from doesn't match any of the cells it is returning. The fact that you don't know this indicates that the formula you're using doesn't in fact do what you think it does.
--UPDATE --
Okay, following your further clarificaiton it seems that you're talking about Cascading Dropdowns aka Dynamic Dropdowns. Lots of info on Google about how to set these up, but you may be interested in an approach I blogged about sometime back that not only provides this functionality, but also ensures that someone can't later on go and change the 'upstream' dropdown without first clearing the 'downstream' one should they want to make a change.
Note that those links talk about a slightly complicated method compared to others, but the method has it's advantages in that it also handles more levels than two, and your DV lists are easily maintained as they live in an Excel Table.
This sounds like an array equation. Try hitting Ctrl+Shift+Enter in the other sheets to validate it as an array equation.
Whenever you need to reference ranges instead of single cells, Excel needs to know that you are working with arrays.
The following multi-match array function fails against a table with only 1 row. However it works as as soon as there is another row added.
{=MATCH("A"&"C",myTable[Col1]&myTable[Col3],0)}
curly brackets added to show array formula
See picture as example
Is there anyway to force this to work for at times my real data may only have 1 row in the table? (And this also works with only one row of data not explicity formatted as a table).
This modification doesn't work either:
=MATCH("A"&"C",myTable[[#Data],[Col1]]&myTable[[#Data],[Col3]],0)
I do not know why but, you can avoid it by using Aggregate:
=AGGREGATE(15,6,(ROW(Table1[Col1])-MIN(ROW(Table1[Col1]))+1)/((Table1[Col1]="A")*(Table1[Col3]="C")),1)
This modification works, for an alternative to #ScottCraner's answer.
{=MATCH("A"&"C",myTable[[#All],[Col1]]&myTable[[#All],[Col3]],0)-1}
Curly brackets added to designate this needs to be entered as an array formula (by pressing Ctrl+Shift+Enter
If you prefer, it seems you can just wrap your original formula in an iferror:
{=IFERROR(MATCH("A"&"C",myTable[Col1]&myTable[Col3],0),IF("A"&"C"=myTable[Col1]&myTable[Col3],1,0))}
This also gives you the opportunity to build in a return value in the case that you do not have a match in the table at all.
While i have seen this topic answered before i cant seem to understand the solution :(
Here is my worksheet:
https://docs.google.com/spreadsheet/pub?key=0AsCQyX3EZ40SdC1FNFBjVDh6d01iY2g0WnVXOU5GeFE&output=xls
As you can see i need the second INDEX in the first sheet to return the second value looked, but instead (as expected) it shows the first one again.
I am not the best with excel, explain slowly and i will understand fast!
Thanks in advance!
Try this "array formula" in Calculator sheet cell A3
=IFERROR(INDEX(IngredientDB!B$1:B$100,SMALL(IF(IngredientDB!$A$1:$A$100=$B$1,ROW(IngredientDB!$A$1:$A$100)),ROWS(A$3:A3))),"")
confirmed with CTRL+SHIFT+ENTER and copied across and down. When you run out of entries you get blanks - assumes up to 100 rows of data, increase as required
If you wanted to go the pivot table route you can start with this as a base and then customize it to your exact liking.:
Start with your info:
Then add a pivot of your data:
Then set the properties as so and then you can select the search terms, you can also change the settings to allow someone to type it in also:
The result will be as so:
Update: File

I have transformed my original data into a game-like context, in which the sheet keeps track of points for completed activities and upon reaching various point amounts, the user goes up in rank. An easy way to see the issue is to enter a 1 (and then 2 and 3) into F15 next to the cell with 500. When you do so, notice how the values in Q5:Q6 change from 0 to 1, but Ranking in C2 which is the SUM function which counts this range does not increase to 3 like it should. And consequently the values in L12 and L14 which are based on it also don't update. Now, if you recalculate, the rank goes up and the L cells update. NOW, cell E3 which is based on the L cells doesn't reflect the correct value, and you have to once again recalculate the sheet for it to update.
Hope all that makes sense - let me know if you need any clarification!
Original Question
Some of my formulas are not updating right away after I have entered in data. Just to get this out of the way before someone suggests it, I DO have the calculation of the workbook set to automatic, and I DON'T open any other workbooks with their calculation method set to manual. So that's not the issue.
I would give specifics on formulas, but I don't think it has anything to do with that. The formula is a simple SUM function which adds together a range. The range updates properly - as soon as I've entered data, the numbers in the range change accordingly. The SUM function should likewise automatically update, but I have to enter data in another cell or press delete in an empty cell (basically, get the sheet to recalculate once again) to get the SUM function to reflect the changes in the range.
The only thing that I can think is that it's because I've enabled iterative calculation (in File > Options > Formulas tab) in order to allow cells to retain their previous value if a certain condition is true, else update their value. My settings are 1 for Maximum Iterations and the default of 0.001 for Maximum Change. However, I've used that before without having issues with a simple SUM function. And I have other just as simple functions in my sheet that DO update properly, so I'm a little confused...
Let me know if any more info would be helpful. Thanks for any suggestions!
UPDATE:
Sorry, I didn't catch that this is for a formula, not function. My bad.
I'll leave the answer up in case someone has the same issue, but with a function. Sorry!
Try adding this inside the code:
Application.Volatile
This will force recalculation for the function each time a cell is changed on the sheet in which this function appears.

You have circular references: cell formula in range S4:AL103 all refer to themselves (under cetain conditions). This will cause excel to stop calculating because it can't resolve the conflict.
You wll need to redesign your formulas
Originally added to my initial post; moved it to an actual answer so that it could be accepted
So I figured out the solution. From doing a little more reading up on iteration, I discovered that in iterative mode, Excel processes cells one at a time, in a certain order (alphabetical, I think?). So if cell A is dependent on cell B, but cell B changes value later in the process, cell A will retain a value based on cell B's old value, rather than the new one, until another recalculation is prompted... OR, until another iteration starts. So, setting maximum iteration to a higher number than 1 fixes the issue. Since I had two cells not updating in the example sheet I gave you guys, it would need to be set at about 3. In my actual sheet, I had to set it at 5.
Thanks for the thoughts! Hope this helps some other confused soul!
