I want to determine if either column H >1 and/or column I >1...basically a yes or no answer...but I don't want a value of 2 if both of them are...I'm having to put whatever formula will do this over in column M because all of the preceding columns are already the product of a query (you'll see that in cell A3)
this is the sheet I'm in
can't you just add them to check if the sum is greater than 1?
=N(H3+I3>1)
N() turns true falses into 1s and 0s

I'm trying to understand this auto-increment formula, that my colleague has written. I understand how arrayformula usually works and also countifs.
Formula from the screen: =ARRAYFORMULA(COUNTIFS(ROW(B2:B), "<="&ROW(B2:B)))
I'm stacked about why ROW(B2:B) (1param in COUNTIFS) as a range works fine. It should be a range, not just a number that ROW function returns.
I have been trying to find an answer, read documentation, but nothing helped.
I think that, for example, for 4th line the formula would look like this (if we seperate from ARRAYFORMULA):
COUNTIFS(ROW(B4:B), "<="&ROW(B4:B)),
COUNTIFS(4, "<=4")
I need to understand this code, not other solutions.
The best way to understand how an ARRAYFORMULA works is to write down the equivalent drag-down formula.
The equivalent drag-down formula for:
=ARRAYFORMULA(COUNTIFS(B2:B, B2:B, ROW(B2:B), "<="&ROW(B2:B)))
is
=ARRAYFORMULA(COUNTIFS($B$2:$B, B2, ROW($B$2:$B), "<="&ROW(B2)))
=ARRAYFORMULA(COUNTIFS($B$2:$B, B3, ROW($B$2:$B), "<="&ROW(B3)))
=ARRAYFORMULA(COUNTIFS($B$2:$B, B4, ROW($B$2:$B), "<="&ROW(B4)))
...
(We only need ARRAYFORMULA because ROW($B$2:$B) is an array formula, which means that if you type it in a cell without wrapping it an an array-enabling function it will only evaluate ROW($B$2))
If we recall the COUNTIFS parameters:
=COUNTIFS(criteria_range1, criterion1, criteria_range2, criterion2)
We can see that in the drag-down formula, every parameter that by default expects a range, becomes an absolute reference and every parameter that by default does not expect a range, is just a single value that increments each row.
This is true for any other function: if a function has a parameter that by default expects a range, when we wrap it in ARRAYFORMULA(), that range stays the same throughout the entire computation, which means that every single value in that range is seen by the array formula at any time. What increments, and therefore is only seen by the array formula on that specific row, are the parameters that do not natively expect a range.
This seems like an obvious observation but I'm sure it's the reason many people are confused about how that formula works.
If you understand this concept, then you can also understand how the other variants of the formula work:
=ARRAYFORMULA(COUNTIFS(B2:B, B2:B, ROW(B2:B), "<"&ROW(B2:B)))
=ARRAYFORMULA(COUNTIFS(B2:B, B2:B, ROW(B2:B), ">="&ROW(B2:B)))
=ARRAYFORMULA(COUNTIFS(B2:B, B2:B, ROW(B2:B), ">"&ROW(B2:B)))
every next row is by logic an incrementation of the previous row +1. what this formula does it checks the given row number against row number. for example, for row 4, COUNTIFS checks if ROW(A4) is smaller or equal to ROW(A4). then the evaluation is "yes, row 4 is equal to row 4" and the output is TRUE. what COUNTIF actually does is counting these TRUE outputs up to every row summing all the previous rows. something like:
rows
COUNTIFS processing
output
counting TRUEs
final output
row 1
row 1 equal to row 1?
TRUE
1st TRUE
1
row 2
row 2 equal to row 2?
TRUE
2nd TRUE
2
row 3
row 3 equal to row 3?
TRUE
3rd TRUE
3
row 4
row 4 equal to row 4?
TRUE
4th TRUE
4
row 5
etc

I have a column of strings of the form
n|m
where n<m are natural numbers and I want to calculate the sum of this column where each cell has value m-n (m minus n). I can calculate the respective values into a separate cell via:
=INDEX(SPLIT(A1,"|"), 0,2)-INDEX(SPLIT(A1,"|"), 0,1)
and sum over those but I would like to do it in one step just as one formula below the specified column in one cell. Is that possible?
Thanks
Try in B1
=ARRAYFORMULA(SUM(IFERROR(INDEX(SPLIT(A1:A,"|"), 0,2)-INDEX(SPLIT(A1:A,"|"), 0,1))))
if you want to get the sum below the last value, i.e. row#8
=ARRAYFORMULA(SUM(IFERROR(INDEX(SPLIT(A1:A8,"|"), 0,2)-INDEX(SPLIT(A1:A8,"|"), 0,1))))
Thank you for your time!
I am trying to make a trade journal in Google Spreadsheets.
What I want is the entry price and exit price of the trades,
Which are cell C10 and cell C11 in the screenshot image below.
I just manually typed the correct value - 960 and 2200.
Fortunately, the entry price for C10 is always what's in cell H2,
Because the first input will always be "Buy" in column F.
However I'm stuck finding the exit value.
I want it to find the last non-zero value of column H, only when column F contains "Sell".
What formula can I write?
enter image description here
You can do it with a combination of
INDEX
QUERY
COUNTA
Query for entries in column H where F is equal to "sell" and H is not 0.
From the retrieved subset of data, get the one with the last index (by counting the total amount of indices with COUNTA).
Sample formula:
=INDEX(
QUERY(F2:H, "select H where (F = 'sell' and H <> 0)"),
COUNTA(
QUERY(F2:H, "select H where (F = 'sell' and H <> 0)")
),
1
)
You can also do it without QUERY() (even though it is a really cool function).
=INDEX(H:H,MAX(IF((F:F="Sell")*H:H,ROW(F:F)),-1))
Find last row number where "Sell" appears in Column F and the corresponding value in Column H is non-zero. Since the row number monotonically increases, MAX() always gives us the last occurrence. If the row says "Buy" instead, or the value is 0, then IF() returns -1. We cannot use 0 because INDEX() evidently returns the whole range if we do that.
Use that row number as an index for column H to get the corresponding value. If no valid value was found, we get a #NUM error, which you can handle with IFERROR() if you'd like.
Note: we can't use a VLOOKUP() and approximate match because Action is unsorted.
I have the following sheet (link). What formula would yield the itemized sums in B2, C2, and D2?
To calculate the value in B2, the formula should check cells B5:B10 and sum the corresponding values from A5:A10 for non-blank cells. Hence: 30+45+30=105.
I have tried ARRAYFORMULA(IF(B5:B10 != ""), sum(A5:A10)) which results in Formula parse error.
Considering that the numbers in column B are not to used (thats what i figured out from your example).
you can use sumIf:
=SUMIF(B5:B10,">0",A5:A10)
so this will check if the cell in column B is greater than 0, then it will add its corresponding value from column A.
please note that if you put a character in the B column the SUMIF will not consider it because we are using ">0" as criterion, instead use ISBLANK.
hope it helps.
Google Spreadsheets, match/lookup in ALL rows, except the current one
I have never come across a method that looks in all rows, except the current.
Say you have a match or vlookup and it looks in ALL the rows except the current one the formula is in.
We use a formula like below that verifies if a certain value already exists (using a MAX), but if it finds itself then the match or vlookup is always 1 (or in error)
A B
1 Formula: Does value 1 from cell A1 exist in column A?
2 Formula: Does value 1 from cell A2 exist in column A?
3 Formula: Does value 1 from cell A3 exist in column A?
4 Formula: Does value 1 from cell A4 exist in column A? Check all except row 4
Something like this
Formula in cell C4: match(A4;A$1:A3&A5:A)
Or Formula in cell C4: match(A4;A:A&[^A4])
You can use this formula from the second row of data onward (B2=):
=IFERROR(MATCH(A2,A$1:A1,0),MATCH(A2,A3:A,0)+ROWS(A$1:A1)+1)
If there is no match above the current cell it will search for a match below, and will return the correct index in the full column range by adding ROWS(A$1:A1)+1 to the below match result.
Copy this formula downward from B2 to B3 and so on.
If you are trying to check whether the value appears in the column except for the current row just use COUNTIF()
Put this formula in B2
=ARRAYFORMULA(IF($A$2:$A="",,IF(COUNTIF($A2:$A,"="&$A2:A)>1,True,False)))
Otherwise please specify what kind of output you want
