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.
I have set of columns that I am attempting to calculate the combined total of those columns then subtract from that total 8, if the difference after 8 is equal to or less than 0 I want to only show zero in the column I am doing this formula in. For those who might ask, I am using the ARRAYFORUMLA cause I want this calculation to repeat as I add new rows, keeping the totals I am seeking on the same row as the calculation is being done onto. So far I have most of this working. Well up to the IF ELSE THEN type of portion. My attempt is/was
=if(LTE((B3:B)+(C3:C)-8,0),ARRAYFORMULA((B3:B)+(C3:C)), 0)
As long as I'm understanding you correctly, I believe this will work:
=if(lte(sum(B2:C)-8,0),0,sum(B2:C))
It's at the top of the row and sums columns B and C. You can add more columns easily this way by either changing B/C to something else or passing more columns in.
Sum-8 is greater than 0
Sum-8 is less than 0
If what you want to do is to add each row to the total but only if its sum is 8 or greater, then your original formula was nearly OK but the two parts of the IF statement should have been reversed
=sum(ArrayFormula(if(LTE((B3:B)+(C3:C)-8,0),0,(B3:B)+(C3:C))))
You could also take most of the brackets out
=sum(ArrayFormula(if(LTE(B3:B+C3:C-8,0),0,B3:B+C3:C)))
and this would also work
=sum(ArrayFormula(if(LTE(B3:B+C3:C,8),0,B3:B+C3:C)))
Short answer
ARRAYFORMULA that can show 0 if the value is less than or equal to zero. Otherwise show the value of that set of data:
=ArrayFormula(IF(LTE(A1:A3,0),0,A1:A3))
Explanation
The basic IF syntax requires the use of scalar values, to use it with arrays, ARRAYFORMULA is required as an outer function:
ARRAYFORMULA(IF(array_logical_expression,array_if_true,array_if_false))
For the specific case described on the body of the question, the corresponding formula is:
=ARRAYFORMULA(IF(LTE(B3:B+C3:C-8,0),0,B3:B+C3:C))

Using arrays in Google Sheets
I'm trying to count the number of times something of a given type occurs and I need this behaviour to automatically expand to inserted rows. Something like:
=Arrayformula(COUNTIFS(I:I,I:I,H:H,H:H,G:G,G:G))
The nested countif formula will result in a correct value when used on a single row but currently the array formula is outputting 1 all the way down.
My data resembles:
Column1 Column2 Column3 Result
--------------------------------------------
apple green eaten x
orange orange noteaten x
apple red eaten x
orange orange noteaten x
apple green eaten x
...
The x column is where the arrayformula would output.
X on Row 1 should look through all the data and count up the number of green apples eaten, the next row would count noneaten orange oranges, and so on. I know that arrayformula doesn't take aggregate functions but I didn't find anything on alternatives to countif.
Unfortunately, in Google Sheets, COUNTIFS can not be iterated over an array, as eg COUNTIF can (at the time of writing this, anyway).
You would need to resort to MMULT, something like:
=ArrayFormula(IF(ROW(G:G)=1,"Result",MMULT((G:G=TRANSPOSE(G:G))*(H:H=TRANSPOSE(H:H))*(I:I=TRANSPOSE(I:I)),SIGN(ROW(G:G)))))
but be aware there appears to be a limitation in Sheets whereby the 2D array formed by G:G=TRANSPOSE(G:G) etc cannot exceed 10 million elements. This corresponds to a maximum of 3162 rows.
Another option is to use concatenation of strings:
=ArrayFormula(COUNTIF(G:G&CHAR(9)&H:H&CHAR(9)&I:I,G:G&CHAR(9)&H:H&CHAR(9)&I:I))
which gets around the "3162" limitation. CHAR(9) is a tab character, but it could be any character that you are certain will not appear in your data.
This is old but I found two workarounds.
Adding an if statement to the ArrayFormula does the trick.
E.g.:
=ArrayFormula(IF(I:I="","",COUNTIFS(I:I,I:I,H:H,H:H,G:G,G:G)))
Otherwise, if you can afford to have an extra column, you could combine the data in your three columns and run a COUNITF on that.
That said, you'd need to include an if statement in that to exclude the count for empty rows.
Column K:
=ArrayFormula(G:G&H:H&I:I)
In the Result Column:
=ArrayFormula(IF(I:I="","",COUNTIF(K:K,K:K)))
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.
How to create a Google Spreadsheet sum() which always ends on the cell above, even when new cells are added? I have several such calculations to make on each single column so solutions like this won't help.
Example:
On column B, I have several dynamic ranges which has to be summed. B1..B9 should be summed on B10, and B11..B19 should be summed on B20. I have tens such calculations to make. Every now and then, I add rows below the last summed row , and I want them to be added to the sum. I add a new row (call it 9.1) before row 10, and a new raw (let's call it 19.1) before row 20. I want B10 to contain the sum of B1 through B9.1 and B20 to contain the sum of B11:B19.1.
On excel, I have the offset function which does it like charm. But how to do it with google spreadsheet? I tried to use formulas like this:
=SUM(B1:INDIRECT(address(row()-1,column(),false))) # Formula on B10
=SUM(B11:INDIRECT(address(row()-1,column(),false))) # Formula on B20
But on Google Spreadsheet, all it gives is a #name error.
I wasted hours trying to find a solution, maybe someone can calp?
Please advise

You are probably looking for formula like:
=SUM(INDIRECT("B1:"&ADDRESS(ROW()-1,COLUMN(),4)))
Google Spreadsheet INDIRECT returns reference to a cell or area, while - from what I recall - Excel INDIRECT returns always reference to a cell.
Given Google's INDIRECT indeed has some hard time when you try to use it inside SUM as cell reference, what you want is to feed SUM with whole range to be summed up in e.g. a1 notation: "B1:BX".
You get the address you want in the same way as in EXCEL (note "4" here for row/column relative, by default Google INDIRECT returns absolute):
ADDRESS(ROW()-1,COLUMN(),4)
and than use it to prepare range string for SUM function by concatenating with starting cell.
"B1:"&
and wrap it up with INDIRECT, which will return area to be sum up.
REFERRING TO BELOW ANSWER from Druvision (I cant comment yet, I didn't want to multiply answers)
Instead of time consuming formulas corrections each time row is inserted/deleted to make all look like:
=SUM(INDIRECT(ADDRESS(ROW()-9,COLUMN(),4)&":"&ADDRESS(ROW()-1,COLUMN(),4)))
You can spare one column in separate sheet for holding variables (let's name it "def"), let's say Z, to define starting points e.g.
in Z1 write "B1"
in Z2 write "B11"
etc.
and than use it as variable in your sum by using INDEX:
SUM(INDIRECT(INDEX(def!Z:Z,1,1)&":"&ADDRESS(ROW()-1,COLUMN(),4))) - sums from B1 to calculated row, since in Z1 we have "B1" ( the 1,1 in INDEX(...,1,1) )
SUM(INDIRECT(INDEX(def!Z:Z,2,1)&":"&ADDRESS(ROW()-1,COLUMN(),4))) - sums from B11 to calculated row, since in Z2 we have "B11" ( the 2,1 in INDEX(...,2,1) )
please note:
Separate sheet named 'def' - you don't want row insert/delete influence that data, thus keep it on side. Useful for adding some validation lists, other stuff you need in your formulas.
"Z:Z" notation - whole column. You said you had a lot of such formulas ;)
Thus you preserve flexibility of defining starting cell for each of your formulas, which is not influenced by calculation sheet changes.
By the way, wouldn't it be easier to write custom function/script summing up all rows above cell? If you feel like javascripting, from what I recall, google spreadsheet has now nice script editor. You can make a function called e.g. sumRowsAboveMe() and than just use it in your sheet like =sumRowsAboveMe() in sheet cell.
Note: you might have to replace commas by semicolons
NOTE
After testing this answer, it will only work if the sum is in a different column due to a circular dependency error. Otherwise, the solution is valid.
It's a bit of algebra, but we can take advantage of Spreadsheets' lower right corner drag.
=SUM(X:X) - SUM(X2:X)
Where X is the column you are working with and X2 is your ending point. Drag the formula down and Sheets will increment the X2, thus changing the ending point.
*You mentioned that you had tens of such calculations to make. So in order to fit your exact need, we would subtract your last summation to get that "middle" range that we wanted.
e.g.
B1..B9 should be summed on B10, and B11..B19 should be summed on B20
Because of the circular dependency error mentioned earlier, I can't solve it exactly and put the sum on the same line, but this could work in other cases where the sum needs to be stored in a different column.
=SUM(B:B) - SUM(B9:B) //Formula on C10 (Sum of B1..B9)
=SUM(B:B) - SUM(B19:B) - B10 // Formula on C20 (Sum of B11..B19)
This is based on #PsychoFish, here is the solution:
=SUM(INDIRECT(SUBSTITUTE(ADDRESS(1,COLUMN(),4),"1","")&"3:"&ADDRESS(ROW()-1,COLUMN(),4)))
Simply replace the "3:" for the row to start sum.
#PsychoFish is correct but cannot be dragged and copied since the column is literal and hard coded, and #Druvision was in the right direction but was wrong... basically ended up with the same issue of having to re-enter the ranges and then sliding the formulas over and over.
You guys are making this harder than you have to. I just leave a couple of empty rows above by "sum" row (you can format them to be filled with color or something to keep them from being inadvertently used), then just add your new rows just above those special rows.
Agree with what user7255446 said that everyone is overcomplicating. Keep one row blank before your sum row. And then whenever you want to insert a new row, click on your blank row and use "Insert row ABOVE" instead of "insert row below". Your sum formula will automatically adjust.
Example: I want to sum from B1 to B19. I leave row 20 blank. In cell B21, put =SUM(B1:B20). Then if you ever need to insert a new row, click on row 20 and choose "Insert row above". The sum formula automatically changes to =SUM(B1:B21) for you. And of course your sum cell is now B22.
General syntax:
=SUM(INDIRECT(cell_reference_as_string1 &":"& cell_reference_as_string2)
with for example:
cell_reference_as_string1 = ADDRESS(ROW(),COLUMN(),4)
cell_reference_as_string2 = ADDRESS(ROW()-1,COLUMN(),4)
I like how #abernier describes the general solution. So far only alphabet-based A1 notation (A being first column, 1 being first row) are being used. It keeps confusing me, especially when thinking of number of columns left of another column. I like the number-based R1C1 notation much better. To use R1C1 notation for INDIRECT, you need to pass FALSE like so:
=SUM(INDIRECT("R1C"&COLUMN()&":R"&(ROW()-1)&"C"&COLUMN(), FALSE))
I hope you find that helpful, too.
OFFSET() can be used/abused for this purpose. Give it the absolute address of the top left of the range, 0 and 0 for the row/column offsets, and the height/width of the range. Let OFFSET() be the argument to SUM(), SUMIF(), etc.
ROW() and COLUMN() are handy when computing the desired height/width. Be sure to remember to subtract one to exclude the current row/column, or else you're liable to end up with a circular reference. If you have header rows/columns, subtract for them too.
For example, to sum everything from A2 down, excluding the current row, try:
=SUM(OFFSET($A$2,0,0,ROW()-2,1))
To sum everything to the left of the current cell, wherever it may be, try:
=SUM(OFFSET(INDIRECT("RC1",FALSE),0,0,1,COLUMN()-1))
Now let's flip things upside down, to show that this works in the other direction. Suppose you want to sum the B column, starting below the current row, until (and including) row #10. Try this:
=SUM(OFFSET($B$10,ROW()-9,0,10-ROW(),1))
You can avoid negative offsets, while still summing column B:
=SUM(OFFSET(INDIRECT("RC2",FALSE),1,0,10-ROW(),1))
Remove the "2" to instead sum the current column:
=SUM(OFFSET(INDIRECT("RC",FALSE),1,0,10-ROW(),1))
(Credit to Tom Sharpe, who commented above.) INDEX() can be used in a range expression. You might prefer this over OFFSET(), so I'm putting it here. The following sums everything from G1 down to the row above the current:
=SUM(G1:INDEX(G:G,ROW()-1))
Here's how I do it.
This formula does not require you to edit or enter anything about the particular column you would like to sum
=SUM(INDIRECT(CONCATENATE(address(1,column(),4),":",LEFT(address(1,column(),4),1))&ROW()-1))
The answer by #PsychoFish led me in the correct way.
The only issue that I had to rewrite the formula again from each column and each sum. So here is the improved formula, which sums the previous 9 cells on the same column, without hardcoding the column or row numbers:
=SUM(INDIRECT(ADDRESS(ROW()-9,COLUMN(),4)&":"&ADDRESS(ROW()-1,COLUMN(),4)))
The only issue is that I had to rewrite the formulas if someone adds or deletes a row. In this case I should change 9 to 10 or 8 corrspondingly.
