I have a Google sheet which has two columns. Column F has a numeric value in it and I want column G to contain the value of column G in the previous row plus the value of column F in the current row, basically a running total.
I'm trying to use an array formula to do the calculation and it works for the first couple of rows but after that Column G contains the same value as Column F.
The formula I'm using is:
=arrayformula(F3:F10+G2:G9)
What am I doing wrong?
In general, nothing should not use its own output as input. Iterative calculation would be required, and that's a trap-laden path to be avoided whenever there's an established alternative. In this case, the usual approach to a Running Total is MMULT and some garnishing.
If your data starts in F2, put this in G2:
=ArrayFormula(IF(F2:F10,
MMULT(
TRANSPOSE((ROW(F2:F10)<=TRANSPOSE(ROW(F2:F10)))*F2:F10),
SIGN(F2:F10)),
IFERROR(1/0)
))
Or, slightly more opaque, but able to cope with negative values:
=ArrayFormula(IF(F2:F10,
MMULT(
TRANSPOSE((ROW(F2:F10)<=TRANSPOSE(ROW(F2:F10)))*F2:F10),
IF({F2:F10}<>0,1,0)),
IFERROR(1/0)
))
a slight alternative would be:
=ARRAYFORMULA(IF(F2:F;
MMULT(TRANSPOSE((ROW(F2:F)<=TRANSPOSE(ROW(F2:F)))*F2:F);
SIGN(F2:F)^2); IFERROR(1/0)))
I've got the following Google spreadsheet:
item have ready need1 need2 need3
A 1 2 1
B 1 2 1 1
C 2 2
etc
I want to fill ready column as follows:
find the first column in need1, ..., needN range which has a non-empty value
if the value found is less or equals the value in have column, set ready column to something cheerful (e.g. yes)
if the value found is larger than the value in have column, don't do anything
So above input, when processed should look like this:
item have ready need1 need2 need3
A 1 2 1
B 1 2 1 1
C 2 yes 2
For the first step I found a suggested solution, which did not work for me:
=INDEX( SORT( FILTER( D10:H10 , LEN( D10:H10 ) ) ,
FILTER( COLUMN( D10:H10 ) , LEN( D10:H10 ) ) , 0 ) , 1 )
(it returns #REF!) Not sure what's wrong with it or how to proceed to the next step.
Thanks in advance!
If you know how many need columns you have, or even just how many columns are on the sheet, this is quite straightforward. If not and you need to look at the entire row, you might have to redesign a bit to avoid a circular reference from the cell with the formula being part of that row.
Your second two steps are fairly simple either way - you want one of two results based on a condition, so you're going to want to use =IF. Your condition is that the 'need' number is less than or equal to the 'have' number, and you want it to say 'yes' if that's true, and nothing if it isn't. So, that gives us:
=IF(need<=have, "Yes", "")
The examples below assume your table above starts from cell A1 in the top left, and that the last column in your sheet is Z
Next we need to find 'need' and 'have'. Finding 'have' is pretty easy - it's just the number in column B.
Finding 'need' is slightly more complicated. You've got the right idea using INDEX and FILTER, but your formula seems a little overcomplicated. Basically we can use FILTER to filter out the blank values, and INDEX to find the first one that is left. First, FILTER:
The range you want to filter from is everything in the same row from column D to column Z (or whatever the final column is), and the condition you want to filter for is that those same cells are not blank. For the formula you're typing into cell C2, that gives us:
=FILTER(D2:Z2, D2:Z2<>"")
Next, INDEX: If you give INDEX an array, a row number, and a column number, it will tell you what is at that the cell where that row and column meet. As we've filtered out the blanks, we just want whatever is left in the first column of our filtered array, which gives us:
=INDEX(FILTER(D2:Z2, D2:Z2<>""), 1, 1)
Or, as we only have one row in our array, and INDEX is pretty smart, simply:
=INDEX(FILTER(D2:Z2, D2:Z2<>""), 1)
So to bring it all together, our final formula for cell C2 is:
=IF(INDEX(FILTER(D2:Z2, D2:Z2<>""), 1)<=B2, "Yes", "")
Then just drag the formula down for as many rows as you need. If your sheet is or becomes wider, just change Z to whatever your last column is.
When you don't know the size of a range, use functions row, column, rows, columns.
Simple formula
Here's an example of what you are looking:
=if(INDEX(FILTER(OFFSET(D2,,,1,COLUMNS(1:1)-column(D2)+1),OFFSET(D2,,,1,COLUMNS(1:1)-column(D2)+1)<>""),1)<=B2,"yes","")
this part of formula:
OFFSET(D2,,,1,COLUMNS(1:1)-column(D2)+1)
returns the range starting from given cell (D2) to the end of Sheet (COLUMNS(1:1)-column(D2)+1)
ArrayFormula
I suggest using ArrayFormula, it'll expand automatically:
=ARRAYFORMULA(if(REGEXEXTRACT(SUBSTITUTE(trim(transpose(query(transpose(OFFSET(D2,,,COUNTA(A2:A),COLUMNS(1:1)-column(D2)+1)),,COLUMNS(OFFSET(D2,,,COUNTA(A2:A),COLUMNS(1:1)-column(D2)+1)))))," ",", "),"\d+")*1<=OFFSET(B2,,,COUNTA(A2:A)),"yes",""))
It assumes that 'Item' column has no blank values.
The solution from #Max Makhrov works, and has the advantage of using a single formula for the whole column.
However, it assumes that all of your columns at the right from your ready column (D) will be need_ columns.
The solution from #dmusgrave also works, provided you remove the extra "=" before INDEX:
=IF(INDEX(FILTER(D2:Z2,D2:Z2<>""),1)<=B2,"Yes","").
However, it makes the same assumption, and also limits at column Z.
Such assumptions seem reasonable, but if they are limiting you, here's how you can have any number of need_ columns starting right of your ready column:
=IF(INDEX(FILTER(INDIRECT( "D"&ROW()&":"&CHAR(67+COLUMNS(FILTER($1:$1,LEFT($1:$1, 4)="need")))&row() ), INDIRECT( "D"&ROW()&":"&CHAR(67+COLUMNS(FILTER($1:$1,LEFT($1:$1,4)="need")))&row() )<>""),1)<=B2,"Yes","")
The idea is simply to replace D2:Z2 (in #dmusgrave's solution) by :
INDIRECT( "D"&ROW()&":"&CHAR(67+COLUMNS(FILTER($1:$1,LEFT($1:$1, 4)="need")))&row() )
Explanation: You start from D at current row, and you go until the last need_ column on the same current row.
CHAR(68) is D, to which you add the number of columns titled need.*, minus one (hence the 67).
Using the same logic, you can easily make your formula more robust/generic, such as not having the need_ columns starting right form the ready column, etc.
Based on this sample data, I have this formula which gives me the accurate results with one major problem... It does not auto-populate to new rows
=arrayformula(if(countif(filter(G$2:G,A$2:A=A2,B$2:B=B2),">"&G2)>0,countif(filter(G$2:G,A$2:A=A2,B$2:B=B2),">"&G2),COUNTIF(filter(E$2:E,A$2:A=A2,B$2:B=B2),"Finished")))
I have tried this formula to see if it will auto-populate to the new rows...
=arrayformula(IF(ISNA(A2:A),,if(countif(filter(G$2:G,A$2:A=A2,B$2:B=B2),">"&G2)>0,countif(filter(G$2:G,A$2:A=A2,B$2:B=B2),">"&G2),COUNTIF(filter(E$2:E,A$2:A=A2,B$2:B=B2),"Finished"))))
...the above formula does auto-populate; however, every value is 1 instead of the correct value.
I tried a simple formula which does not do everything the above does but might help troubleshoot. I was under the suspicion that the above formula was only displaying results of the first row over and over. To test I tried this formula...
=arrayformula(IF(ISNA(A2:A),,indirect("g"&ROW(indirect("g2:g"&counta(G2:G))))))
...it turns out that the above formula does display the results from G2 into each row. If I could figure out the reason why, I am sure I could take the concept from the solution to this simple formula and add it to the above more complex one.
Please, try this formula:
=ArrayFormula(if(
mmult(
--(A2:A=TRANSPOSE(A2:A))*
--(B2:B=TRANSPOSE(B2:B))*
--(G2:G<TRANSPOSE(G2:G)),
row(A2:A)^0)>0,
mmult(
--(A2:A=TRANSPOSE(A2:A))*
--(B2:B=TRANSPOSE(B2:B))*
--(G2:G<TRANSPOSE(G2:G)),
row(A2:A)^0),
mmult(
--(A2:A=TRANSPOSE(A2:A))*
--(B2:B=TRANSPOSE(B2:B)),
--(E2:E="Finished"))
)
)
Caution! It works slow, so it's better to delete blank rows in the worksheet. Even better to use this formula in 2 steps. Step 1 formula:
=ArrayFormula(mmult(--(A2:A=TRANSPOSE(A2:A))*
--(B2:B=TRANSPOSE(B2:B))*
--(G2:G<TRANSPOSE(G2:G)),
row(A2:A)^0))
And step 2 formula:
=ArrayFormula(mmult(--(A2:A=TRANSPOSE(A2:A))
*--(B2:B=TRANSPOSE(B2:B)),
--(E2:E="Finished")))
Open ranges overload this formula. It also could work faster if you use:
offset(E2,,,counta(E2:E)) instead of E2:E
I've been at this problem for a while now. I am trying to sum numbers under a specific column when the rows equal a certain text and then display that sum on a different sheet. So far I came up with this formula: =IF(EXACT(A2,Table!A2:A)=TRUE,SUM(Table!C2:C)); however the only problem is that is sums everything in column C (which makes sense).
I wish there was a way to do something like the following: SUM(Table!C2:C where EXACT(A2,TABLE!A2:A)=TRUE). I've also tried the SUMIF(), DSUM(), and QUERY() functions to no avail. I must be getting logically tripped up somewhere.
Figured it out: =SUM(FILTER(Table!E4:E, EXACT(Table!A4:A,A4)=TRUE)).
=sum ( FILTER (b1:b10, a1:a10 = "Text" ) )
// the above formula will help you to take the sum of the values in column B when another column A contain a specific text.
The formula is applicable only in Google Spreadsheets
I have a formula that will take the data from the past 30 days (column A are dates, column F has the data which is always either blank or above 0).
=AVERAGEIFS(F3:F, A3:A,">"&TODAY()-30, F3:F, ">0")
I need another, similar formula to apply to column H, however H will have negative numbers and 0. I would have thought this would work but it is simply not ignoring the blanks and the average does not match when I do a regular average and manually select the non blanks.
=AVERAGEIFS(H3:H, A3:A,">"&TODAY()-30, H3:H, "<>''")
What am I missing?
Apparently, it's just:
=AVERAGEIFS(H3:H, A3:A,">"&TODAY()-30, H3:H, "<>")
That unfortunately wasn't very clear in the documentation.
