Google Sheets: Cell formula NOT working in ARRAYFORMULA - google-sheets

I've a regularly updating sheet of daily foreign exchange rates (descending order sorted).
I've written a cell formula, which works fine if I drag it to the end.
=IFNA( VLOOKUP(A2,USD_TRY!$A$2:$B$3289,2,FALSE), INDEX(USD_TRY!$A$2:$C$3289, MATCH(A2,USD_TRY!$A$2:$A$3289,-1), 3 ) )
Column A2:A is daily dates, merged from 2 different sheets of daily rates and different currencies (so it skips some dates) but it has more dates than the column USD_TRY!A2:A. This formula gets the Price rate from column USD_TRY!B2:B if the VLOOKUP() date matches but if it doesn't match then it gets the Open rate from column USD_TRY!C2:C a row before (a day after) the closest match. However, if I convert the same formula to ARRAYFORMULA() then the VLOOKUP() part works fine but the INDEX(MATCH()) part gives a wrong result of USD_TRY!C2 every time.
IF(
AND(NOT(ISBLANK(A2:A)), NOT(ISBLANK('USD_TRY Historical Data'!A2:A)), NOT(ISBLANK('USD_TRY Historical Data'!B2:B)), NOT(ISBLANK('USD_TRY Historical Data'!C2:C)) ),
ARRAYFORMULA(
IFNA(
VLOOKUP(A2:A,'USD_TRY Historical Data'!A2:B,2,FALSE),
INDEX('USD_TRY Historical Data'!A2:C, MATCH(A2:A,'USD_TRY Historical Data'!A2:A,-1), 3 ) )
)
)
}
How do I correct the ARRAYFORMULA() and is there any simpler way to get the correct results as array?
Source data:
Correct output (with cell formula):
Wrong result (with array formula):

try:
=ARRAYFORMULA(IFNA(
VLOOKUP(A2:A4, E2:F6, 2, 0),
VLOOKUP(90000-A2:A4, {90000-E2:E6, G2:G6}, 2, 1)))

ARRAYFORMULA is only populating the first row

I have financial data that I am trying to summarize in a format that can be used by a line chart.
The example spreadsheet is here.
In my source data on the left, I have an entry per Date, Symbol, Account. I need to transform this data so there is a row per Date and a column for each Symbol. I will SUM Total Value regardless of account.
I found a way to pull a unique Date (see H2), and then transpose unique Symbols into columns (see I1).
I also found a way to use SUMIFS to get the aggregation I want (take a look at cell I2), but I can't figure out how to use ARRAYFORMULA to apply this value to all rows in column I.
I know I can drag my formula from I2 down to I3,I4,I.. etc, but this sheet is part of a larger project so I'd like it to auto-populate as dates are added to H.
From what I've read ARRAYFORMULA should apply the formula to multiple rows. What am I missing?
Thanks
use:
=QUERY(A1:F, "select A,sum(F) where A is not null group by A pivot B", 1)
Use formulas like this
=ARRAYFORMULA(IF(H2:H="",,SUMIFS($F$2:$F, $A$2:$A, $H2, $B$2:$B, I$1)))
Add IF(H2:H="",,

Multiple search criteria in google sheets

I am trying to make an automated attendance sheet
I have 2 google sheets,
the first one is the responses from a google form that has the name of the students and the date they attended, so it will have duplicated name and duplicated dates.
The second sheet have the names of the students on the left and the dates on the top.
I am trying to automate the second sheet to put "P" under the date that the student was present and "A" when his name is not in the first sheet with that date.
Best i could do was adding an extra column with the letter "p" in the first sheet and using dget to search for the name and date and output the "p" from the extra column, which only worked for one of them for some reason.
=DGET('ATTENDANCE DATE !B:D, "AT", {"NAME", "DATE"; $H$4,12})
I tried to use query also but no luck.
=QUERY('ATTENDANCE DATE'!B7:D,"
SELECT D
WHERE B MATCHES'"&$H9&"' AND C MATCHES '"&I$2&"'
")
Sorry if my question was confusing.
A good solution is to use 4 formulas to do exactly what you like. Each formula has a function:
B1 formula: generates the headers for all the dates with data.
B2 formula: generates the sub-header with the day of the week for each date.
A3 formula: gets all the names.
B3 formula: gets the attendance values for all users. This is the most complexs one.
Here is how it looks:
A
B
1
< fromula 1 >
2
name
< formula 2 >
3
< formula 3 >
< formula 4 >
Before starting there a few things to note
Questions and more information
Please, if at any point you don't understand something, let me know (I'd like this to be a nice resource on how to do formulas).
Also, at the end I left links to all the formulas I use, so you can see what they exactly do.
Locale
I'm using the English locale. this means that I'm using commas , to separate arguments (instead of ;) and array literals (instead of \). if you have function formatting errors, look into it, as this could be the issue.
Sheet names
I've changed the Sheet's names as they are very long and made the formulas harder to follow. Fell free to replace the names on the formulas back to the original name. Here is how I named them:
ATTENDANCE RESPONSES FROM GOOGLE FORM ⟶ Att
LATE/ABSENT RESPONSES FROM GOOGLE FORM ⟶ Late
Formula format
Almost all formulas require "ARRAYFORMULA" to show their full effects. I won't be adding it everywhere as it could get confusing. If you'd like to see what a formula part (doesn't have an equal sign =) does, go to a sheet and do:
=arrayformula(
<paste formula part>
)
Also, parts that are in <some name> are not literal, and represent the code named in between the brackets.
Formula 1
It can be split into 2 formulas:
Get the ordered unique dates
Add a Reason column for each date
Get the dates
The first thing you can use is UNIQUE to get only the unique ones and SORT to sort them. You also need to get them from both sheets as there could be a day that everyone is absent or another where everyone came. SORT(UNIQUE({Att!B2:B; Late!B2:B})) does most of the trick but you also get empty cells. because of that we add a filter. So together:
SORT(UNIQUE(FILTER({Att!B2:B; Late!B2:B}, {Att!B2:B; Late!B2:B}<>"")))
Adding Reason
The problem of it is that the number of column is not fixed (it grows over time). A good workaround is to concatenate the date with a separator and Reason and then split it again. This only works for columns and generates a 2 column, result. Then it can be moved into a single column by using FLATTEN.
FLATTEN(SPLIT(
<previous part>&"␟Reason",
"␟"
))
I'm using ␟ (Symbol For Unit Separator) as the separator as it indicates exactly what it is and is very-very unlikely to be included in the sheet.
If you use that you'll see that the date is shown in numbers. To Change that we'll format the date before concatenating and splitting:
FLATTEN(SPLIT(
TEXT(
<previous part>,
"dd/mmm/yyyy"
)&"␟Reason",
"␟"
))
Now we need to make it a row instead of a column. There is a function that does that: TRANSPOSE.
Complete formula 1
=ARRAYFORMULA(
TRANSPOSE(FLATTEN(SPLIT(
TEXT(
SORT(UNIQUE(FILTER({Att!B2:B; Late!B2:B}, {Att!B2:B; Late!B2:B}<>""))),
"dd/mmm/yyyy"
)&"␟Reason",
"␟"
)))
)
Formula 2
To add the day of the week we need to format the date with TEST and the format ddd, which is the short-version of the name of the day of the week (Mon, Tue, etc).
TEXT(B1:1, "ddd")
Note though that if the value formatted is already text, it will pass it. Because of that, we need to only do this for the columns with dates. One way that I found is to get the even-numbered columns. TO do that, it's a combination of COLUMN (get the number of the column), MOD (get the module), and IF:
IF(MOD(COLUMN(B1:1),2)=0, <formatted text>, "")
This does what we want but we now get "Sun" on columns that there is nothing. The reason is that empty cells are being interpreted as zeros. Because of that we need to add another condition: the cell is not empty.
IF((MOD(COLUMN(B1:1),2)=0)*(B1:1<>""), <formatted text>, "")
To do the logical and I'm using the product because the formula AND would return a single value ("eats" the passed array).
Complete
=ARRAYFORMULA(
IF(
(MOD(COLUMN(B1:1),2)=0)*(B1:1<>""),
TEXT(B1:1, "dddd"),
""
)
)
Formula 3
The third formula is the simplest and should be self-explanatory:
=ARRAYFORMULA(
SORT(UNIQUE(Att!A2:A))
)
Formula 4
This is the final formula. This formula is based on using VLOOKUP to know the value for each person and date.
Making a table to VLOOKUP into
The way of doing that is to generate a key by joining both values into a single text value and set the other values on the other columns. To prevent problems we add a separator to make sure that there are no combination that will be equal. Here is how the table to lookup into looks like:
< name >␟< date >
< status >
< reason >
< name >␟< date >
< status >
< reason >
< name >␟< date >
< status >
< reason >
⋮
⋮
⋮
The key for the first sheet is:
Att!$A$2:$A&"␟"&Att!$B$2:$B
To add the other 2 columns (Present and an empty one) we use a similar trick to Formula 1: we add a separator to split it later on. Because we already are using ␟ for the key, we need another one. In the same block there is another meant for this cases: ␞ (Symbol For Record Separator).
Att!$A$2:$A&"␟"&Att!$B$2:$B&"␞"&"Present"&"␞"&""
or joining the literal text:
Att!$A$2:$A&"␟"&Att!$B$2:$B&"␞Present␞"
This need to be filtered, as there are empty values, which we don't want. We'll use FILTER to do exactly that:
FILTER(Att!$A$2:$A&"␟"&Att!$B$2:$B&"␞Present␞", Att!$A$2:$A<>"", Att!$B$2:$B<>"")
For the second sheet, we do something similar but including the other columns:
FILTER(Late!$A$2:$A&"␟"&Late!$B$2:$B&"␞"&Late!$C$2:$C&"␞"&Late!$D$2:$D, Late!$A$2:$A<>"", Late!$B$2:$B<>"", Late!$C$2:$C<>"")
Note that I've added more conditionals.
This needs to be vertically joined. This can be done with an array literal:
{
<Attr formula>;
<Late formula>
}
Then we need to split the rows to expand into the multiple columns:
SPLIT(
{
FILTER(Att!$A$2:$A&"␟"&Att!$B$2:$B&"␞Present␞", Att!$A$2:$A<>"", Att!$B$2:$B<>"");
FILTER(Late!$A$2:$A&"␟"&Late!$B$2:$B&"␞"&Late!$C$2:$C&"␞"&Late!$D$2:$D, Late!$A$2:$A<>"", Late!$B$2:$B<>"", Late!$C$2:$C<>"")
},
"␞"
)
Using VLOOKUP
Now that we have where to lookup into, we can do it like so:
VLOOKUP(
A3:A&"␟"&C1:1,
<lookup table>,
2,
false
)
Note that the key that we are looking up is the one we generate. Also, this will get the values only below the dates (will fail otherwise).
Adding the reason
Since we know that the cells which are for the reason fail (since <name>␟Reason shouldn't exist), we can use IFERROR to detect it:
IFERROR(
<vlookup status>,
<vlookup reason>
)
The formula for reason is almost identical to the one for status. The only changes are that we lookup into the third column (instead of the second) and we look one to the left:
VLOOKUP(
A3:A&"␟"&OFFSET(C1:1, 0, -1),
<lookup table>,
3,
false
),
Using OFFSET instead of a range ensures that they have the same size.
Final error management
This formula fails when the key doesn't have name or date (which is outside the table or there that entry missing). For that case we add another IFERROR:
IFERROR(
<formula>,
""
)
Complete formula
=ARRAYFORMULA(
IFERROR(
IFERROR(
VLOOKUP(
A3:A&"␟"&C1:1,
SPLIT(
{
FILTER(Att!$A$2:$A&"␟"&Att!$B$2:$B&"␞Present␞", Att!$A$2:$A<>"", Att!$B$2:$B<>"");
FILTER(Late!$A$2:$A&"␟"&Late!$B$2:$B&"␞"&Late!$C$2:$C&"␞"&Late!$D$2:$D, Late!$A$2:$A<>"", Late!$B$2:$B<>"", Late!$C$2:$C<>"")
},
"␞"
),
2,
false
),
VLOOKUP(
A3:A&"␟"&OFFSET(C1:1, 0, -1),
SPLIT(
{
FILTER(Att!$A$2:$A&"␟"&Att!$B$2:$B&"␞Present␞", Att!$A$2:$A<>"", Att!$B$2:$B<>"");
FILTER(Late!$A$2:$A&"␟"&Late!$B$2:$B&"␞"&Late!$C$2:$C&"␞"&Late!$D$2:$D, Late!$A$2:$A<>"", Late!$B$2:$B<>"", Late!$C$2:$C<>"")
},
"␞"
),
3,
false
)
),
""
)
)
Final touches
The final result is something like this.
After that you can simply add formats to your taste. You can also add conditionals ones to more easily see the result.

I've completed a not-so-neat solution for you, starting on Row10 in the 'AUTO ATTENDANCE' sheet. It's divided into 4 parts:
The formula in cell D10 auto-populates Row10 with dates and empty cells in between:
=SPLIT(JOIN("|REASON|",SORT(UNIQUE({'ATTENDANCE RESPONSES FROM GOOGLE FORM'!$B$2:$B;'LATE/ABSENT RESPONSES FROM GOOGLE FORM'!$B$2:$B}))),"|")
Row 11 gets the day of the week from row 10 (if the cell above it contains a date:
=IF(ISDATE(D10),TEXT(D10,"dddd"),)
Cell C12 gets all unique names from both response sheets (auto-populates the name column):
=SORT(UNIQUE({'ATTENDANCE RESPONSES FROM GOOGLE FORM'!$A$2:$A;'LATE/ABSENT RESPONSES FROM GOOGLE FORM'!$A$11:$A}))
Cell D12 onwards gets the form responses and does the auto-attendance:
=IF($C12<>"", IF(ISDATE(D$1), IF(IFERROR(QUERY('ATTENDANCE RESPONSES FROM GOOGLE FORM'!$A$2:$B,"select A where A = '"&$C12&"' AND B = datetime '"&TEXT(D$1, "yyyy-mm-dd hh:mm:ss")&"'"), "noresult")=$C12, "PRESENT", IFERROR(QUERY('LATE/ABSENT RESPONSES FROM GOOGLE FORM'!$A$2:$D, "select C where A = '"&$C12&"' and B = datetime '"&TEXT(D$1, "yyyy-mm-d hh:mm:ss")&"'"), "NO RESPONSE")), IFERROR(QUERY('LATE/ABSENT RESPONSES FROM GOOGLE FORM'!$A$2:$D, "select D where A = '"&$C12&"' and B = datetime '"&TEXT(C$1, "yyyy-mm-d hh:mm:ss")&"'"), )), )
The cells with yellow background contain formulae, the ones with green background do not contain formulae but will be auto-populated as the forms get more responses. The single cell with red background (C11), you'll have to write manually ;) Hope this solves your issue!

Why my ArrayFormula is giving error? How do I correct it? (I'm not looking for another Arrayformula as solutions!)

I wanted a ArrayFormula at C1 which gives the required result as shown.
Entry sheet:
(Column C is my required column)
Date Entered is the date when the Name is Assigned a group i.e. a, b, c, d, e, f
Criteria:
The value of count is purely on basis of Date Entered (if john is assigned a on lowest date(10-Jun) then count value is 1, if rose is assigned a on 2nd lowest date(17-Jun) then count value is 2).
The value of count does not change even when the data is sorted in any manner because Date Entered column values is always permanent & does not change.
New entry date could be any date not necessarily highest date (If a new entry with name Rydu is assigned a on 9-Jun then the it's count value will become 1, then john's (10-Jun) will become 2 and so on)
Example:
After I sort the data in any random order say like this:
Random ordered sheet:
(Count value remains permanent)
And when I do New entries in between (Row 4th & 14th) and after last row (Row 17th):
Random Ordered sheet:
(Doesn't matter where I do)
I already got a ArrayFormula which gives the required result:
={"AF Formula1"; ArrayFormula(IF(B2:B="", "", COUNTIFS(B$2:B, "="&B2:B, D$2:D, <"&D2:D)+1))}
I'm not looking for another Arrayformula as solutions. What I want is to know what is wrong in my ArrayFormula? and how do I correct it?
I tried to figure my own ArrayFormula but it's not working:
I got Formula for each cell:
=RANK($D2,FILTER($D$2:$D, $B$2:$B=$B2),1)
I figured out Filter doesn't work with ArrayFormula so I had to take a different approach.
I took help from my previous question answer (Arrayformula at H3) which was similar since in both cases each cell FILTER formula returns more than 1 value. (It was actually answered by player0)
Using the same technique I came up with this Formula which works absolutely fine :
=RANK($D2, ARRAYFORMULA(TRANSPOSE(SPLIT(VLOOKUP($B2, SUBSTITUTE(TRIM(SPLIT(FLATTEN(QUERY(QUERY({$B:$B&"×", $D:$D}, "SELECT MAX(Col2) WHERE Col2 IS NOT NULL GROUP BY Col2 PIVOT Col1", 1),, 9^9)), "×")), " ", ","), 2, 0), ","))), 1)
Now when I tried converting it to ArrayFormula:
($D2 to $D2:$D & $B2 to $B2:$B)
=ARRAYFORMULA(RANK($D2:$D,TRANSPOSE(SPLIT(VLOOKUP($B2:$B, SUBSTITUTE(TRIM(SPLIT(FLATTEN(QUERY(QUERY({$B:$B&"×", $D:$D}, "SELECT MAX(Col2) WHERE Col2 IS NOT NULL GROUP BY Col2 PIVOT Col1", 1),, 9^9)), "×")), " ", ","), 2, 0), ",")), 1))
It gives me an error "Did not find value '' in VLOOKUP evaluation", I figured out that the problem is only in VLOOKUP when I change $B2 to $B2:$B.
I'm sure VLOOKUP works with ArrayFormula, I fail to understand where my formula is going wrong! Please help me correct my ArrayFormula.
Here is the editable sheet link
if I understand correctly, you are trying to "rank" B column based on D column dates in such way that dates are in theoretical ascending order so if you randomize your dataset, the "rank" of each entry would stay same and not change based on the randomness you introduce.
therefore the correct formula would be:
={"fx"; INDEX(IFNA(VLOOKUP(B2:B&D2:D,
{INDEX(SORT({B2:B&D2:D, D2:D}, 2, 1),,1),
IFERROR(1/(1/COUNTIFS(
INDEX(SORT(B2:D, 3, 1),,1),
INDEX(SORT(B2:D, 3, 1),,1), ROW(B2:B), "<="&ROW(B2:B))))}, 2, 0)))}
{"fx"; ...} array of 2 tables (header & actual table) under each other eg. ;
outer shorter INDEX or longer ARRAYFORMULA (doesnt matter which one) is needed coz we are processing an array
IFNA for removing possible #N/A errors from VLOOKUP function when VLOOKUP fails to find a match
we VLOOKUP joint B and D column B2:B&D2:D in our virtual table {} and returning second 2 column if there is an exact match 0
our virtual table {INDEX(SORT({B2:B&D2:D, D2:D}, 2, 1),,1), ...} we VLOOKUP from is constructed with 2 columns next to each other eg. ,
we are getting the first column by creating an array of 2 columns {B2:B&D2:D, D2:D} next to each other where we SORT this array by date/2nd column 2, in ascending order 1 but all we need after sorting is the 1st column so we use INDEX where we bring all rows ,, and the first column 1
now lets take a look on how we getting the 2nd column of our virtual table by using COUNTIFS which will mimic the "rank"
IFERROR(1/(1/ is used to remove all zero values from the output (all empty rows would have 0 in it as the "rank")
under COUNTIFS we put 2 pairs of arguments: "if column is qual to column" and "if row is larger or equal to next row increment it by 1" ROW(B2:B), "<="&ROW(B2:B))
for "if column is qual to column" we do this twice and use range B2:D and sort it by date/3rd column 3 in ascending order 1 and of this we again need only the 1st column so we INDEX it and return all rows ,, and first column 1
with this formula you can add, remove or randomize your dataset and you will always get the right value for each of your rows
as for why your formula doesnt work... to not get #N/A error for vlookup you would need to define the end row of the range but still, the result wont be as you would expect coz formula is not the right one for this job.
as mentioned there are functions that are not supported under AF like SUM,AND,OR and then there are also functions which work but in a different way like IFS or with some limitations like SPLIT,GOOGLEFINANCE,etc.
I have answered you on the tab in your shared sheet called My Practice thusly:
You cannot split a two column array as you have attempted to do in cell CI2. That is why your formula does not work. You can only split a ONE column array.
I understand you are trying to learn, but attempting to use complicated formulas like that is going to make it harder I'm afraid.

In Google Sheets, how to check if Cell A (Date) is within the Date range of Cell B and C

I have a sheet with a timeline that shows a month per row in column A and an amount in USD next to that month in column B.
I want to be able to specify amounts in column G with a start and end date for that amount in columns E and F.
What I am trying to achieve is that the values in column B are automatically calculated by looking at the start and end dates specified in columns E and F and then taking the corresponding value from column G if the date in column A falls in between the date range specified in E and F.
I have found many suggestions for similar problems online but wasn't able to get any of them to work for my specific case. Any help is very welcome
You could do it as an array formula like this:
=ArrayFormula(mmult((text(indirect("A2:A"&count(A2:A)+1),"YYMM")>=text(TRANSPOSE(indirect("`E3:E"&count(E3:E)+2)),"YYMM"))*(text(indirect("A2:A"&count(A2:A)+1),"YYMM")<=text(transpose(indirect("F3:F"&count(F3:F)+2)),"YYMM"))*transpose(indirect("G3:G"&count(G3:G)+2)),(INDIRECT("G3:G"&count(G3:G)+2)+2)^0))
The idea is to develop a 2D array where the rows are the months and the columns are the amounts for matching time periods. Then use the standard Mmult method to get the row totals of the array.
Using indirect for the ranges makes the formula longer but using full-column references would be slow as it would result in a nearly 1000 X 1000 array for a default-sized sheet.
EDIT 1
Or shorter
=ArrayFormula(mmult((text(indirect("A2:A"&count(A2:A)+1),"YYMM")>=text(TRANSPOSE(indirect("E3:E"&count(E3:E)+2)),"YYMM"))
*(text(indirect("A2:A"&count(A2:A)+1),"YYMM")<=text(transpose(indirect("F3:F"&count(F3:F)+2)),"YYMM"))
,INDIRECT("G3:G"&count(G3:G)+2)))
because you can combine the row totals step with multiplication by column G.
EDIT 2
Alternatively you could just employ a much simpler pull-down formula using SUMIFS:
=ArrayFormula(sumifs(G$3:G,eomonth(E$3:E,-1)+1,"<="&A2,F$3:F,">="&A2))
This uses Eomonth to change all the start dates to the first of the month so they can be compared to the dates in column A correctly. The formula still has to be entered as an array formula because of the Eomonth calculation.
Note
The equivalent pull-down formula to the original array formulas above would be
=ArrayFormula(sumifs(G$3:G,text(E$3:E,"YYMM"),"<="&text(A2,"YYMM"),text(F$3:F,"YYMM"),">="&text(A2,"YYMM")))
but this gives zero for all rows - the reason for this is not obvious to me at time of writing.

How to do VLOOKUP based on multiple criteria and return the latest rows result?

Currently when I use Vlookup, it provides for first matching occurrence of data.
I receive data into a spreadsheet by date, i.e., a record existing for every project with values for status field. I build a consolidated report in a new tab at project level, I need to populate the 'STATUS' column for each project.
The status field value could remain same for few days but would change on a certain date. If I use VLOOKP(Project#, SampleData! Project#:Status, 7 , 0) I would get for first match i.e., most likely will get always 'In-Progress' as result
How can I add another criteria in VLOOKUP to search for max of dates upon the matching project# & return the result?
Google Sheet Link
If projects are sorted by date in ascending order, you can use LOOKUP function to get last status:
=ArrayFormula(LOOKUP(2,1/(A11=$B$2:$B$7),$H$2:$H$7))
if not sorted, then try following:
=ArrayFormula(LOOKUP(2,1/((A11=$B$2:$B$7)*(MAX($A$2:$A$7*(A11=$B$2:$B$7))=$A$2:$A$7)),$H$2:$H$7))
Explanation:
Here is used LOOKUP feature if search key is not found, the lookup will return the last closest matching key in the range with a lower value. In first formula LOOKUP search for value 2 while expression 1/(A11=$B$2:$B$7) returns array with errors and ones {1/TRUE,1/TRUE,1/TRUE,1/FALSE,1/FALSE,1/FALSE} => {1,1,1,DIV/0,DIV/0,DIV/0} so LOOKUP returns value from third row in range $H$2:$H$7.
In the second formula, by analogy.
Using VLOOKUP
Leveraging the ARRAYFORMULA function you can build a search_key for your range:
This will basically multiply the Boolean result of the EQ function (=) for all the possible dates and then take the maximum.
Note: Boolean values are also represented as 1 for TRUE and 0 for FALSE, so every date that is not for the corresponding Project code will result in a very old timestamp.
I will then use this as a search_key to get the status (col 8) for the Project code subset range (built with the IF function):
=ARRAYFORMULA(
VLOOKUP(
MAX($A$2:$A$7*(A11=$B$2:$B$7)),
IF(A11=$B$2:$B$7, $A$2:$H$7),
8,
FALSE
)
)
Dragging down this formula for each project code will return its last status.
Using QUERY
If you prefer to use the QUERY formula instead of the VLOOKUP here is an example:
The query is based on a sub-query that basically leverages the max() aggregate function to find the max date for a specific Project code.
Then it uses this maximum date and the Project code as a key to be sure to exclude date duplicates that belong to other Project codes.
=QUERY(
$A$1:$H$7,
"select H where A = date '"& TEXT(
Query(
$A$2:$H$7,
"select max(A) where B = "&A11&" label max(A) ''",
1
),
"yyyy-MM-dd")&"'",
0
)
Here as well dragging down the formula will return the Project last status.
