return array of #NA - arrays

I have a list of item numbers.Some of them don't have details associated with them. I would like the list of item numbers that don't have info associated. they can be identified with #N/A error.
I'm running excel 2007.
i am using this array formula to return the associated details. which are in column A
=IF(ISERROR(VLOOKUP(J12,A:H,{2,3,4,5,6,7,8},FALSE)),"",VLOOKUP(J12,A:H,{2,3,4,5,6,7,8},FALSE))
if the lookup can't find the associated item number in column a it returns blanks, otherwise it returns the associated data.
the ones that error, i need a list of those.
is there a formula or a vba macro to get this information?
thanks for your time

As XORLX said: why you are using {values} as its picking items from column B?
Anyway you can change your formula with
=IFERROR(VLOOKUP(J12,A:H,{2,3,4,5,6,7,8},FALSE),"N/A")
So in case of error it will give N/A which you can later filter.
But I think you want result as in this pic
Sample File
Where
K6=IFERROR(INDEX(A:H,MATCH(J6,A:A,0),(IF(INDIRECT("B"&MATCH(J6,A:A,0))<>"",2,IF(INDIRECT("C"&MATCH(J6,A:A,0))<>"",3,IF(INDIRECT("D"&MATCH(J6,A:A,0))<>"",4,IF(INDIRECT("E"&MATCH(J6,A:A,0))<>"",5,IF(INDIRECT("F"&MATCH(J6,A:A,0))<>"",6,IF(INDIRECT("G"&MATCH(J6,A:A,0))<>"",7,IF(INDIRECT("H"&MATCH(J6,A:A,0))<>"",8))))))))),"N/A")
In my example I am looking for Joy which is in Row 2.
Now after finding Row 2 it will go and check 2nd Column B which is empty so it will go for 3rd C and so on and when will return the data from the 1st column and if find nothing then will return error.

Vlookup within results of a multiple-match lookup

I am trying to find a way to return values from a table like the bottom table:
The tables are provided externally and my understanding is that I can't run filters or sorts as the table is full of extra irrelevant data that would not sort properly across all columns.
I'm approaching this twofold:
firstly, I wanted to return the row information for any entry in the table that has a CPT matching the lookup value.
Second, (where I'm stuck)--when the lookup returns a DESC that corresponds to a matched CPT, the goal would be to also pull in any Code A/Code B entries that correspond to that DESC value.
I found an existing formula that worked for the first part, shown below. (apologies for formatting--SO keeps flagging my draft as having unformatted code).
IFERROR(INDEX($B$3:$B$3000,SMALL(IF(I$2=$A$3:$A$3000,ROW($A$3:$A$3000)- MIN(ROW($A$3:$A$3000))+1,""), ROW()-1)),"")
Currently, the aforementioned formula does return the DESC entries for any matching CPTs and I use vlookup to pull the rest of the relevant columns for a corresponding row.
I'm coming up short in cases where there are multiple Code A/Code B entries for a given DESC, as the lookup only returns information for the row containing the matching CPT and not any relevant codes contained in subsequent rows.
I was thinking I'd have to use something similar to the existing lookup formula to identify a matched row and then display any subsequent rows containing Code entries until the next row with a non-blank CPT entry.
Unfortunately, I don't know if that's actually the best way to approach this. Any resources/suggestions are greatly appreciated.

Find and repeat a cell value if values match

My spreadsheet is collecting data from a form
On another tab I'm showing the responses that match "Lesson day" with "Today's date" (in the example, all the lessons are showed).
As you can see, the "e-mail" field is filled out only once.
Is there a way to automatically fill the "e-mail" field in the second tab? Maybe matching the "Student Code" with the "e-mail" fields in the first tab?
I've tried the MATCH() function but it returns only the position. I feel like I need to combine MATCH() with other functions but I have no idea about where to start
EDIT: Having the email adresses on another column would work too.
SOmething like: if the "Student Code" in the 2 tabs matches, show the email adress for that "Student code"
try:
=ARRAYFORMULA(IFNA(VLOOKUP(D4:D, FILTER({form!E2:E, form!G2:G}, form!G2:G<>""), 2, 0)))
change form to match the sheet name of your form sheet
As suggested, I created an auxiliary table (just called Sheet7) and getting closer to the desired result
In A column I used
=UNIQUE(Lessons!E:E)
In column B I used
=INDEX(Lessons!A:M, MATCH(A2,Lessons!E:E,0),7)
Then, on my second spreadsheet, I could get all the e-mail adress using the following formula
=INDEX(Sheet7!A:B, MATCH(D4,Sheet7!A:A,0),2)
I've tried to use ArrayFormula on the auxiliary table
ARRAYFORMULA(if(A2:A="",,INDEX(Lessons!A:M, MATCH(A2:A,Lessons!E:E,0),7)))
But it doesn't work. It shows only the email adress matched from the cell A2, ignoring A3, A4,...
A different approach:
Make an extra column in your form responses sheet called "Student E-mail".(In this example it is column "I")
In row 2 of that column, write the following formula:
=ARRAYFORMULA(IF(ISBLANK(G2:G),VLOOKUP(F2:F,INDIRECT("F$2:G"&ROW(I2:I),TRUE),2),G2:G))
Use that column for the emails in your other tab (hide the original email column)
Update:
Using array formula, you don't have to manually drag & drop. And it keeps going as new rows are added.
Usually MATCH is combined with INDEX
You should build an auxiliary table with one column for names and another for ee-mails.
To build the auxiliary table from the collected data you could use something like this
=UNIQUE(FILTER({Lessons!E:E,Lessons!G:G},LEN(Lessons!G:G)))
The above is better than using a formula for each column as this prevent having mismatching data.
INDEX / MATCH usually doesn't return the "expected" results in an ARRAYFORMULA. Instead use VLOOKUP.
NOTES:
Please bear in mind that every time that you edit a value the formula will be recalculated. If you have a lot of formulas (like when doing a fill down to copy a formula to all the cells in a column) or having an ARRAYFORMULA with open ended references i.e. G2:G this could affect your spreadsheet performance.
If you go for using an ARRAYFORMULA, use ARRAY_CONSTRAIN to limit the number of rows returned by your formula.

Excel: Array formula to return the column data that matches multiple criteria

I would like to submit an Excel problem I tried to solve for the past few days. I am not allowed to use macro, only formulas.
I have 3 tables (see link):
The first one (purple) contain a list of employees and their initials, no duplicates;
The second one (blue) is the main database (+ 500 columns), where all the employees codes are reported and each check mark (ΓΌ) represent the specific options related to that employee; this table is always modified (employees come and go, options are added, etc.);
The third one (Green) is the table that we need to make functional; when we select the name of an employee (yellow), it returns the matching initials (orange); we would like this table to automatically search the initials of the employee in the blue table heading and return the Codes that match the check marks in the respective column; I need a particular array formula to do so.
As you can notice, I calculated various formulas tests and, although I might be on the right path, I lack the necessary skills to create a complex formula that will return the matching codes of the preferences (check marks) from the array column. Does someone have an idea what should be modified to achieve this goal ? Thank you all for any solution you can propose.

Excel array function return all fields found with index and match

Here is the array function I am using:
=IFERROR(INDEX('Master Data'!$D$2:$D$153,MATCH(1,(B9='Master Data'!$J$2:$J$153)*('Master Data'!$W$2:$W$153=1),FALSE)),"")
Where D is the name of a project, J is a persons name and W is a flag to check if they are assigned to a project either equal to 0 or 1. B is also an instance of the persons name that is built up from a seperate list.
It basically references the master data and returns any rows with the criteria specified. However a single person may have two instances where the assigned flag is equal to 1 and thus as the master data is filtered different results are given back by the function.
Another problem I have is that the persons name is not repeated either so maybe the best way would be to start populating the names in the assigned table from the master data as well.
As requested here is an slight example of the data. On the left is the master data, the middle is the assigned table thats being built and the right is the list of employees that builds up the names in the assigned table.
Please note that there is two instances of david smith in the master data but only one in the assigned table as its being built with the employees list.
What I was thinking was to build up the names in the assigned table from the master data using an array where the assigned indicator is equal to 1 and to completely scrap the employees list, but I'm really unsure if this is possible or how to go about it.
Or even if there was some sort of way to select a few columns from the master data where the assigned indicator = 1?
Not sure if I understood it right. But the problem how to list multiple lookup results is achievable with SMALL function in combination with getting an array of ROW numbers.
For example have a sheet like this:
Then formulas are:
F4 downwards:
=COUNTIFS($B:$B,$E4,$C:$C,1)
G4 and then copied in G4:J8:
{=INDEX($A$1:$A$1000,SMALL(IF($B$1:$B$1000=$E4,IF($C$1:$C$1000=1,ROW($1:$1000))),COLUMN(A:A)))}
But if the goal is only to have a filtered list of all assigned resources, then the formulas could be
E13:
{=INDEX($B$1:$B$1000,MATCH(1,($C$1:$C$1000=1)*1,0))}
E14 downwards:
{=INDEX($B$1:$B$1000,MATCH(1,(COUNTIF($E$13:$E13,$B$1:$B$1000)=0)*($C$1:$C$1000=1),0))}
Formulas in {} are array formulas. These are entered into the cell without the curly brackets and then [Ctrl]+[Shift]+[Enter] is pressed to finish.
I have not handled the error values for better understanding the formulas. You can later hide the error values with IFERROR. You seems to know how to do this.

Create array with vlookup

I want to conditionally grab lines from a database-style spreadsheet in Google Spreadsheets (a list with a name, location, description, price) after checking the value with a vlookup - I've used this a while ago and expected it to CONTINUE an array across for the other columns next to the one 'looked up', but it seems my memory fails me here and it just retrieves the 'searched out' value.
=vlookup("Yes",'All 2014-15'!A2:G,2)
This formula basically finds the first value of the desired rows and should create a 'Selected items from 2014-15' list, but I can't work out how to expand it to produce a list of all the rows I want. Is there a simple way to retrieve this, I've tried playing with arrayformula but no success.
I can change the index simply to get the other values across, but if this could be filled out through an array too that would be preferable...?
Can you try this...
=FILTER('All 2014-15'!A2:G,'All 2014-15'!A2:A="Yes")
Edit:
As suggested by Immx, added apostrophes to sheet name and the second range changed to A2:G to A2:A assuming the yes/no data is in A column.
