I have a list of days and times in column A. Column B is a dollar value for each time value.
I want to get a specific time for each day and list the price in the next column. I have this right now:
The formula for column J is this:
=filter(A11:B,(mod(A11:A,1)*24)>=4.5,(mod(A11:A,1)*24)<=4.6)
This formula filters 4:30AM and the price associated with it.
Formula for column L is this:
=filter(A11:B,(mod(A11:A,1)*24)>=9.5,(mod(A11:A,1)*24)<=9.6)
Which filters only 9:30AM for each day and the price that goes with it.
As you can see, the dates stop matching when column J is 8/12/2021 and column L is 8/13/2021. This is because column L didn't have 9:30AM for 8/12/2021 so it skipped to 8/13/2021.
How can I make so that one of the columns skip a date if the other column doesn't match that time? I don't know if I explained that well but in the example above, column J should skip 8/12/2021 because column L didn't have 8/12/2021.
Another way of dealing with this issue is perhaps using UNIQUE and FILTER formulas but I'm not sure how that could be done. Any help would be greatly appreciated!
Here's a link to the spreadsheet: https://docs.google.com/spreadsheets/d/1TvP0_UsYJbLb5bscx2e4nTEnSkP5roBZpP8aIGdl414/edit?usp=sharing
I'm not 100% sure, but if you need to filter values so the time element is 09:30 and 04:30, then hide values where a date only occurs once (ie. no 09:30 value or no 04:30 value), you could use:
=arrayformula(filter(
filter(A11:B,(round(mod(A11:A,1)*24,2)=9.5)+(round(mod(A11:A,1)*24,2)=4.5)),
countif(int(filter(A11:A,(round(mod(A11:A,1)*24,2)=9.5)+(round(mod(A11:A,1)*24,2)=4.5))),int(filter(A11:A,(round(mod(A11:A,1)*24,2)=9.5)+(round(mod(A11:A,1)*24,2)=4.5))))>1)
)
Adjust >1 at the end to whatever logic you need (=2, <>1 etc).
You can also add sort() around everything if you need to.
Explanation:
It turns out that mod(A11,1)*24 doesn't round particularly well, so I suggest round(mod(A11:A,1)*24,2).
Therefore to filter the date/times for 9.30am and 4.30am, you can apply:
round(mod(A11:A,1)*24,2)=9.5
and
round(mod(A11:A,1)*24,2)=4.5
like this:
=arrayformula({filter(A11:B,(round(mod(A11:A,1)*24,2)=9.5)+(round(mod(A11:A,1)*24,2)=4.5))})
filter is usually AND but to get OR condition it's filter(A:B,(A=1)+(A=2))
This gets the dates only:
=arrayformula(int(filter(A11:A,(round(mod(A11:A,1)*24,2)=9.5)+(round(mod(A11:A,1)*24,2)=4.5))))
Then this counts how many times a date appears:
=arrayformula(countif(int(filter(A11:A,(round(mod(A11:A,1)*24,2)=9.5)+(round(mod(A11:A,1)*24,2)=4.5))),int(filter(A11:A,(round(mod(A11:A,1)*24,2)=9.5)+(round(mod(A11:A,1)*24,2)=4.5)))))
Combining the elements gets the solution.
I'll add a tab to your sheet.
You could filter each list on finding a match for each date (integer part of datetime) in the other list:
In J:
=filter(A11:B,(mod(A11:A,1)*24)>=4.5,(mod(A11:A,1)*24)<=4.6,isnumber(match(int(A11:A),int(filter(A11:A,(mod(A11:A,1)*24)>=9.5,(mod(A11:A,1)*24)<=9.6)),0)))
In L:
=filter(A11:B,(mod(A11:A,1)*24)>=9.5,(mod(A11:A,1)*24)<=9.6,isnumber(match(int(A11:A),int(filter(A11:A,(mod(A11:A,1)*24)>=4.5,(mod(A11:A,1)*24)<=4.6)),0)))
Note
Plz see Aresvik's answer for a possibly better approach to rounding, but note that 4:30 (3/16) actually has an exact representation as a binary decimal so rounding errors aren't an issue here.
I need to write a formula that enters 'Y' if the patient is up to date with their immunizations based on their record and age, and 'N' if they are not. Age (D$) is in months and I have a column for every immunization (8 weeks(E$), 12 weeks(F$), 16 weeks(G$), 1 year(H$), 3 years and 4 months(I$)) which is marked as either ("Y" or colored Grey) as well as a final column which the formula is being entered into(J$). Any ideas what formula I need to use?
So far I have been thinking to use an IFS statement { =IFS(D$>=2, AND(E$="Y"),"Y")}. Although I can see the limitations to using this.
For every immunization, the patient is not up to date if the corresponding cell is blank and their age is older than the immunization date. You want to check this for multiple immunizations. You can use COUNTIFS to evaluate two (or more) conditions.
=IF(COUNTIFS(E3:I3,"",E$1:I$1,"<="&D3)>0,"N","Y")
Explanation:
COUNTIFS returns the number of shots for which the patient is not up to date.
IF returns N if the previous value is greater than 0, Y otherwise.
Note that I'm assuming the information on the number of months corresponding to each immunization (E$1:I$1 in the formula above) is present somewhere in the sheet or that you can add it. If this is not the case, you would indeed need to use IFS or something similar.
Is there a way to take a date in one row and auto calculate another date in another column 10 days out?
ex: (column a) 12/11/20 -auto calculate the date 10 days from then
and put in (column d) 12/21/20.
So anytime I enter a date and need the 10 day out date it just auto calculates so I don't have to keep entering the date over and over again.
This is possible by using ARRAYFORMULA().
ARRAYFORMULA enables the display of values returned from an array formula into multiple rows and/or columns and the use of non-array functions with arrays.
Try this: =Arrayformula(TO_DATE(IF(A1:A="","", A1:A+10))).
Example:

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'm sure this is doable and I'm just not finding the solution in the documentation, so big thanks in advance for your help. I want to calculate sales growth month over month.
For example, I'm posting this question on 10/22/2014. Calculating sales thus far for this month is easy, but I also need to know what sales were for the first 22 days of LAST month.
I already have a column containing the values for each day this month, and another column containing the values for each day last month. All I need to do is a way to sum the values for the first 22 days of last month.
Column AH = A list of the dates for last month: 9/1/2014, 9/2/2014...
Column AI = A helper column containing only the DAY of the month of the value in Column AH: 1,2,3,4...
$AJ35 = The day of today's date =DAY(TODAY())
Column AN = The numbers I want to (conditionally) sum
Why won't this formula work?
=SUMIF(AI1:AI34,"<=$AJ35",AN1:AN34)
It calculates a sum of 0.
If I take out the comparison ("<=$AJ35") and manually insert a number, it works fine:
=SUMIF(AI1:AI34,"<=22",AN1:AN34) returns a value of 362, as expected.
That is because you have put a cell reference inside a string (surrounded by double quotes)
which means that google is trying to compare against a literal string "$AJ35"
you have to concatenate the cell reference and the operator like so:
=SUMIF(AI1:AI34,"<=" & $AJ35,AN1:AN34)
