Getting last non-empty column on each row Google Sheets - google-sheets

I have this data as output from an ARRAYFORMULA:
A
B
C
test1
test2
test3
test1
test1
test2
test1
test2
test3
And would like to have this output:
D
test3
test1
test2
test3
How do I get the output above? Having issues with using INDEX and can only pass a single column. If I pass 3 as the column parameter, it will get blank cells on the 2nd and 3rd row. I'm not sure how to proceed after this.

You could create an arrayformula to do this in a single go:
Formula in D1:
=INDEX(REGEXEXTRACT(TRANSPOSE(QUERY(TRANSPOSE("|"&A1:C),,COLUMNS(A1:C))),"([^|]*)[|\s]*$"))
Note: I assumed that "Getting last non-empty column on each row..." meant not all previous column are populated.

In general rules of formula you can user below formula-
=INDEX($A$1:$C$4,ROW(A1),COUNTA(A1:C1))

Referencing a cell's row value using a formula

Suppose my excel sheet looks like this:
Name
Houses
Cars owned
column D
John
3
3
=A&MAX(30,3)
Harry
2
4
..
Vik
5
1
..
..
p
k
..
...
q
n
..
In column D, I want to return the row in column A that corresponds to the larger of the two values in cells B2 and C2. So in cell D2, I would want to return "Vik" because the larger of the two values in B2 (3) and C2 (3) is 3. And the value in cell A3 is Vik.
So in order to arrive at my result, I would input something like ="A"&MAX(B2,C2) in D2.
But suppose my formula was a lot more complex and with different data.
=IFERROR(ArrayFormula(ADDRESS(MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""),,IF($A$1:$D6=B7,COLUMN($A$1:$D6)),"")),MAX(IF($A$1:$D6=B7,COLUMN($A$1:$D6),"")))),"")
and I wanted the result of the first chunk of the formula (from ADDRESS() onwards)
MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),"") (which is 3, say) to be the row number that is input into
MAX(IF($A$3:$D3=B7,COLUMN($A$1:$D6),"")) for the range inside the IF condition.
(notice how $A$1:$D6 changed to $A$3:$D6)
So, going by the tabular example above, I would simply input MAX(IF("$A$"&MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""):$D6=B7,COLUMN($A$1:$D6),"")) and that should do the trick. Except it doesn't and I get a formula parse error which I cannot resolve.
Here is the specific excel sheet I'm working on: https://docs.google.com/spreadsheets/d/12U8U7Jp4FscobIvgr4_sADJB_oSdIHrboCk02cxF_u0/edit?usp=sharing
Can anyone see what I'm doing wrong? The solution, I think, should be simple enough but I can't seem to figure it out.
Sorry if it's a bit long but I've been struggling with this for a while now.
I hope this formula will help
=ARRAYFORMULA(IFNA(VLOOKUP(QUERY(TRANSPOSE(QUERY(TRANSPOSE(B2:C6);"select "&JOIN(",";"max(Col"&row(B2:C6)-1&")")));"select Col2+1 label Col2+1''");{row(A:A)\A:A};2;False)))
Solved using the indirect function and ampersand concatenation.
New function would be: =IFERROR(ArrayFormula(ADDRESS(MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""),,IF($A$1:$D6=B7,COLUMN($A$1:$D6),""))),MAX(IF(INDIRECT("$A$"&(MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""))))):$D6=B7,COLUMN($A$1:$D6),"")))),"")

Number rows for each unique value using arrayformula in google sheet

A B
DOG 1
DOG 2
DOG 3
DOG 4
CAT 1
CAT 2
BIRD 1
B1 is where the formula goes.
I'm trying to use arrayformula to number each row that contains the same value in column A. The number should change when the value changes. I was trying to use countif and indirect but it seems indirect doesn't work with arrayformula.
the way to do this type of cumulative count is with a countifs() using ROW() as a second parameter. So in B1, you would put:
=ARRAYFORMULA(IF(A:A="",,COUNTIFS(A:A,A:A,ROW(A:A),"<="&ROW(A:A)))
hope this helps.

Googlesheet merge 2 cells in next column based on their content

I have a Googlesheet with Column A= ID like B-124992 or D-133739 and several different ID's as well, Column B= Title description. I want to Merge only the "B-" and "D-" -like ID's with their respective Title description. I'm using ArrayFormula in column C like:
= ArrayFormula(IF(ISNUMBER(FIND({"B-","D-"};'BacklogData'!A2));A2&" - "&B2;""))
The result is merging as expected but the output is distributed in column C (shows all "B-" merge results) and column D ((shows all "D-" merge results).
How can I get the results all in column C?
In C2 try:
=ArrayFormula(if(len(B2:B); if(regexmatch(A2:A; "(B-|D-)"); A2:A&"-"&B2:B;);))
This will reference the colA and output the concatenation of col A and colB if col A starts with either B- or D.
NOTE: you will have to erase all formulas you currently have in col C.
Hope that helps ?
EDIT: not sure if you are referencing another sheet, but in that case you will have to add in the sheet name, like you did in the example you gave.
I don't think you need an array formula for this - all you need is an OR condition in a standard formula:
=IF(OR(LEFT(A2,2)="B-",LEFT(A2,2)="D-"),A2&" - "&B2,"")
and copy as far down column C as you need. Since this is not an array, it will only return one result per cell which is what you want.

Display a range of filtered values as a comma-delimited list in one cell on a Google sheet?

Two sheets, one called Core Data, one called Schedule. The Schedule sheet needs to take information about deadlines from Core Data and display it concatenated in deadline-order. (Simple example with numbers and letters instead of dates and tasks given below.)
Here's what I have so far in 'Schedule' (cell B2 specifically in this case):
=JOIN(", ", FILTER('Core Data'!A2:A, 'Core Data'!B2:B=A2))
It's saying no matches are found so I assume this is a problem with the filter component of the formula. However, I've checked the help pages and can't see a problem with the condition I've created.
The formula should:
Get all the values in the given range (cells A2 downward on a 'Core Data' sheet),
Filter them so that only those with certain values are selected. (The information from 'Core Data' should only be selected if the date in the same row on column B matches the date in the cell in the A column on the Schedule sheet.)
Join all these values together and list them as a comma-delimited list.
Example (without dates, for ease):
Core Data sheet:
A | B
-----
a | 5
b | 7
c | 5
d | 3
Schedule sheet (or what it should look like):
A | B
---------
3 | d
5 | a, c
7 | b
Any idea what is going wrong with my formula or if there is an easier way to solve this problem?
The error message I was getting in the cell is:
Error: No matches are found in FILTER evaluation.
It turns out that the cell I was trying this formula on simply had no matches from the filter (no dates corresponded) but instead of returning empty it threw an error. This sounds simple but it's an annoying quirk for me that the cell didn't end up empty which made me assume the formula was at fault.
While the example in the question works you can quickly break it by adding an extra row to the 'Schedule' table with "8" as the value in the A column and the formula in B:
A | B
---------
3 | d
5 | a, c
7 | b
8 | N/A
The "8" throws an error since it isn't found in the 'Core Data'.
Conversely, on my original spreadsheet, When I tried the formula in a cell which did correspond to a noted deadline, it worked.
I found the solution here is to add an IFERROR function to the formula to deal with this.
So a formula that works for this is:
=JOIN(", ", IFERROR(FILTER('Core Data'!A:A, 'Core Data'!B:B=A5)))
One does not use the second IFERROR argument as advised in Google's own helpsheet. I tried putting in an empty array at first ({}) but this threw a different error. It seems if you miss the argument out, the JOIN knows it has nothing to work with and the cell ends up with a nice blank value.

Lookup value based on latest matching criteria

Below is an example of a table I have, what I am trying to do is get the value in the value column for a specific criteria based on the last occurrence (not including today's date).
So in the example below I want to find the value for the last occurrence of 'A', which is 12.
I think this can be done using an Index-Match, I just can't get my head around it though.
For example
Todays Date: 15/12/2013
---------------------------------|
|Date | Criteria | Value
|--------------------------------|
|12/11/2013 | A | 3 |
|16/11/2013 | B | 6 |
|27/11/2013 | C | 7 |
|3/12/2013 | A | 12 |
|5/12/2013 | B | 8 |
|15/12/2013 | A | |
----------------------------------
EDIT:
I would also like to add that this formula will be in a different sheet to the table above. The sheet reference in the formula also needs to be dynamic, it will draw the sheet name from another cell.
I would use this formula:
=index(C:C,max(arrayformula(match(filter(A:A,B:B="A",C:C<>""),A:A,0))),1)
This formula assumes that your data is in the columns A,B,C and for every "A" value in the Criteria column, the Date is different. (If that's not the case, then this formula won't work, see below.
Let's look the formula inside from outside:
filter(A:A,B:B="A",C:C<>"") - This will result with the dates where there is an "A" in the Criteria column, and where the Value column is not empty.
arrayformula(match(filter(A:A,B:B="A",C:C<>""),A:A,0)) - In this step we basically find the row number in which those dates are present. The match function will search for the dates (counted in step 1). The arrayformula is needed because there will be more results.
max(arrayformula(match(filter(A:A,B:B="A",C:C<>""),A:A,0))) - This will find the maximum row number (The maximum row number which contains an "A" in the Criteria column)
index(C:C,max(arrayformula(match(filter(A:A,B:B="A",C:C<>""),A:A,0))),1) - Finally, we use the INDEX function to navigate to the value, which has the maximum row number.
Now, if you want this formula to work on another sheet, you should write, instead of for example:
=index(C:C,... => =index(Data!C:C,...
Assuming that your data is in your Data worksheet.
If you want to this sheet to be dynamic, it's a bit tricky. Let's assume, that you're getting the value of the sheet name from the G1 cell. Then you should write:
=index(indirect(concatenate(G1,"!C:C")),...
This is not so pretty as you should do this for every occasion when it occurs in that long formula (described earlier). Instead you can do some pre-work.
Let's write this to your H1 cell: =concatenate(G1,"!C:C") - If in the G1 cell the sheet name is "Data", then the H1 cell should contain: Data!C:C, similarly you can add to the
H2 cell: =concatenate(G1,"!A:A"),
H3 cell: =concatenate(G1,"!B:B")
Now you can write (and that's the final answer for your question I think):
=index(indirect(H1),max(arrayformula(match(filter(indirect(H2),indirect(H3)="A",indirect(H1)<>""),indirect(H2),0))),1) - where H1,H2,H3 will reference to your Data sheet's columns.
I hope it helps.
Use the following formula to accomplish that.
Formula
=QUERY(
B1:D6, // data
"SELECT D // select
WHERE // where clause
C = 'A' AND // first criterium
D IS NOT NULL // second criterium
ORDER BY B DESC // order by
LIMIT 1, // limit
0" // headers
)
for copy/paste
=QUERY(B1:D6, "SELECT D WHERE C = 'A' AND D IS NOT NULL ORDER BY B DESC LIMIT 1", 0)
Explained
The clue to the formula is the usage of the ORDER BY and the LIMIT options within the QUERY formula. The WHERE clauses will prepare the result in the first place. Next, column B (the dates) is ordered descendingly (highest first). The LIMIT option sets the amount of rows to be displayed at 1.
Example
I've created an example file for you: Lookup value based on latest matching Criteria
I appreciate this is a slightly old question, but there is a way that I achieved the goal of filtering an array which I found both more conceptually straightforward, and also more generally applicable than the other answers I have seen, using vlookup's definitional ability to pick the first matching value in an array.
PROBLEM, RESTATED:
Assuming sample data:
A...B...C...D...E, created by a google form
A is the form entry date
B, C and D are entries from a list (let's assume they are e.g. product name, geography, and sales date)
E is the value
If a new value is entered for a particular product, in a geography, on a date, then I want this to be used in preference to the older version of that same data.
SOLUTION:
If, in your form, you create three new columns:
F Unique test
G Test cells combined
H Unique cells
Then in column G, you create a combination of all the cells you want to test on (in this case B, C and E)
cell G2: "=arrayformula(B2:B & char(9) & C2:C & char(9) & D2:D)"
The next column is a restatement of the cells you want to filter based on (in this case the date in A)
cell H2: "=arrayformula(A2:A)"
And then finally in column F we actually undertake the test:
cell F2: "=arrayformula(A2:A=vlookup(G2:G,sort({G2:H},2,false),2,false))"
Breaking that down, the vlookup (vlookup(G2:G,[RANGE],2,false) compares the data in G2, G3...Gn with a [RANGE], which is a virtual array consisting of two columns, G and H, pre-sorted according to cell H in descending order.
i.e. For any unique value of G (the combination of test data) the vlookup will return the largest value of H
The last part is a simple comparison to the original data (A2, A3... An) to return TRUE or FALSE based on whether it is the latest version of the unique value.
A final step if needed would be to create a new sheet with "=filter('Form Responses 1'!A:E,'Form Responses 1'F:F=TRUE) to recreate the data without the older versions.
Hope this helps.
