I have an Excel sheet with dates in the rows. A given month should be used only once in a row. How can I filter out, if there are two dates in the same row from the same month?
For example I have the following array, and I would like to have as a result, that there is a match in this row (2012-03).
2012-03-04 2012-02-05 2012-04-06 2012-03-07 2012-10-08 2012-11-09 2012-12-10
I have tried to combine aggregate and match functions, but I cannot find out how to do it properly.
One of my codes, of course it gave an error:
=aggregate(9,6,(MATCH("*"&LEFT(A8,7)&"*","*"&LEFT(b8,7)&"*",0), MATCH("*"&LEFT(b8,7)&"*","*"&LEFT(c8,7)&"*",0)))
Ok, now I have tried another way, and I could get a solution, but with a code which is like a km long...I have first created a new dataset, cutting down the days by using: =""&LEFT(A8,7)&""
Then I have compared all the cells in a given row of my new dataset. Could someone help me how to shorten the exact( ) parts? The aim is to compare all.
=if((or(exact(A2, B2), exact(A2,C2),exact(A2,D2),exact(A2,E2),exact(A2,F2),exact(A2,G2),exact(A2,H2),exact(A2,I2),exact(A2,J2),exact(A2,K2),exact(A2,L2),exact(A2,M2),exact(A2,N2),exact(A2,O2),exact(A2,P2),exact(A2,Q2),exact(A2,R2),exact(B2,C2),exact(B2,D2),exact(B2,E2),exact(B2,F2),exact(B2,G2),exact(B2,H2),exact(B2,I2),exact(B2,J2),exact(B2,K2),exact(B2,L2),exact(B2,M2),exact(B2,N2),exact(B2,O2),exact(B2,P2),exact(B2,Q2),exact(B2,R2),exact(C2,D2),exact(C2,E2),exact(C2,F2),exact(C2,G2),exact(C2,H2),exact(C2,I2),exact(C2,J2),exact(C2,K2),exact(C2,K2),exact(C2,L2),exact(C2,M2),exact(C2,N2),exact(C2,O2),exact(C2,P2),exact(C2,Q2),exact(C2,R2),exact(D2,E2),exact(D2,F2),exact(D2,G2),exact(D2,H2),exact(D2,I2),exact(D2,J2),exact(D2,K2),exact(D2,L2),exact(D2,M2),exact(D2,N2),exact(D2,O2),exact(D2,P2),exact(D2,Q2),exact(D2,R2),exact(E2,F2),exact(E2,G2),exact(E2,H2),exact(E2,I2),exact(E2,J2),exact(E2,K2),exact(E2,L2),exact(E2,M2),exact(E2,N2),exact(E2,O2),exact(E2,P2),exact(E2,Q2),exact(E2,R2),exact(F2,G2),exact(F2,H2),exact(F2,I2),exact(F2,J2),exact(F2,K2),exact(F2,L2),exact(F2,M2),exact(F2,N2),exact(F2,O2),exact(F2,P2),exact(F2,Q2),exact(F2,R2),exact(G2,H2),exact(G2,I2),exact(G2,J2),exact(G2,K2),exact(G2,L2),exact(G2,M2),exact(G2,N2),exact(G2,O2),exact(G2,P2),exact(G2,Q2),exact(G2,R2),exact(H2,I2),exact(H2,J2),exact(H2,K2),exact(H2,L2),exact(H2,M2),exact(H2,N2),exact(H2,O2),exact(H2,P2),exact(H2,Q2),exact(H2,R2),exact(I2,J2),exact(I2,K2),exact(I2,L2),exact(I2,M2),exact(I2,N2),exact(I2,O2),exact(I2,P2),exact(I2,Q2),exact(I2,R2),exact(J2,K2),exact(J2,L2),exact(J2,M2),exact(J2,N2),exact(J2,O2),exact(J2,P2),exact(J2,Q2),exact(J2,R2),exact(K2,L2),exact(K2,M2),exact(K2,N2),exact(K2,O2),exact(K2,P2),exact(K2,Q2),exact(K2,R2),exact(L2,M2),exact(L2,N2),exact(L2,O2),exact(L2,P2),exact(L2,Q2),exact(L2,R2),exact(M2,N2),exact(M2,O2),exact(M2,P2),exact(M2,Q2),exact(M2,R2),exact(N2,O2),exact(N2,P2),exact(N2,Q2),exact(N2,R2),exact(O2,P2),exact(O2,Q2),exact(O2,R2),exact(P2,Q2),exact(P2,R2),exact(Q2,R2))),"same month","ok")
Thank you in advance.
I am not sure if there is a better way, but this is how I'd tackle the problem based on my Excel knowledge:
Add data of dates above in cells A1-G1
On row below date add formulas for dates: A2=DATE(A1) ..... G2=DATE(G1)
At the end of the original row of dates add the numbers 1 thru 12:
using formula cell H1=1, I1=H1+1 ..... S1=R1+1
After the months on row 2:H2=COUNTIF($A2:$G2,H1) ..... S2=COUNTIF($A2:$G2,S1)Counting frequency for each of the 12 months
T2=MAX(H2:S2)
Then select on cell T2being more than 1.
Here it is as a Google sheet (you can download it and open in Excel if you want)
Maybe this will help. Assume that the range of dates is in $A$1:$G$1. Also assume that the entries are numerical dates; if they are instead text you can handle this by using the DATEVALUE function. Then we can get the years and months of the range with:
{=YEAR($A$1:$G$1)}
{=MONTH($A$1:$G$1))
This and all other formulas must be entered as array formulas (CrtlShiftEnter).
We next convert back to a date, but use 1 for the day, so that all dates get shifted to the first day of the month (this means that any dates from the same month are shifted to the same date):
{=DATE(YEARS,MONTHS,1)}
We can produce an NxN comparison of the shifted dates by:
{=TRANSPOSE(SHIFTED_DATES)=SHIFTED_DATES}
We can count the number of True's in this array by:
{=SUM(--(ARRAY))}
If there we no dates from the same month we'd expect this to sum to N because this method compare each date to itself as well as the other dates. The causes the N elements on the main diagonal of this array to be True. If any dates are in the same month off-diagonal elements will also be True. So to detect if there are dates from the same month we make the comparison:
{=SUM(--(ARRAY)) > N}
or more generally:
{=SUM(--(ARRAY)) > COUNT($A$1:$G$1)}
Rolling all of these up into one formula:
=IF(SUM(--(TRANSPOSE(DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1))=DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1)))>COUNT(DATE(YEAR($A$1:$G$1),MONTH($A$1:$G$1),1)),"same month","ok")
If your dates are in a range other than $A$1:$G$1 then make the appropriate substitutions.
Hope that helps.
I'm trying to sum the values in sheet GLTB column D where the value in column A starts with 2.21 and the value in column E is equal to the date in the cell A1. I tried this formula:
=SUMIFS(GLTB!$D$3:$D$26522,GLTB!$A$3:$A$26522,"2.21*",GLTB!$E$3:$E$26522,GLTB!$A$1)*-1
The problems:
The date in A1 doesn't appear anywhere else on the GLTB sheet, so I should get 0 for a sum, but I don't. I get some number that doesn't correspond to anything I can find.
I can make all the values in column D where column A starts with 2.21 equal to 0 (or any other number) and it has no effect on the result of the formula.
I tried this formula based on answers to other questions:
=SUMIFS(GLTB!$D$3:$D$26522,GLTB!$A$3:$A$26522,"2.21*",GLTB!$E$3:$E$26522,GLTB!"="&$A$1)*-1
This just changes the last criterion reference. However, Excel gives me a formula error response.
Any ideas?
This should get you a little closer:
=SUMIFS(GLTB!$D$3:$D$26522,GLTB!$A$3:$A$26522,">=2/21/16",GLTB!$E$3:$E$26522,GLTB!$A$1)*-1
This assumes that column A contains date values which are formatted as string. If these values are not date values, then please give some example of what cell contents in column A.
Note: I'm not clear on why you're searching for "2.21*" so I used the >= operator. That can be changed, or we could add additional criteria to the SumIfs based on your needs.
Other things to be careful of:
Ensure that column E and cell A1 both contain the same type of data (either date formatted as string, or string data representing dates. If you have inconsistent data types, the equivalence test in your Criteria2 (GLTB!$E$3:$E$26522,GLTB!$A$1) will not return the desired results.
To start with, you should format your data as table. To do this, use "Start > Format as table". This will also give you the option of giving your table a name, e.g. data. Basically this makes performing the following steps easier.
From then on, you don't need to reference with GLTB!$A3:$A26522anymore, but can use data[ColumnA].
I'm assuming you have a column ValueA with something in there that might start with 2.21, then ValueD which you want to sum and DateE which should be equal to a certain date.
The formula you are looking for is not SUMIF, but the much better SUMPRODUCT, as this allows you to check multiple conditions.
The final formula will look like this:
=SUMPRODUCT((data[DateE]=A1)*(LEFT(data[ValueA],4)="2.21")*data[ValueD])
Now what does this do. SUMPRODUCT first builds a product and then sums that up. Let's assume the following values:
A1 = 2016-03-01
DateE = 2016-03-01
ValueA = 2.213454
ValueD = 3
The formula will then do the following:
(2016-03-01=2016-03-01) is 1
("2.21" = "2.21) is 1
3 is 3
1*1*3 = 3
Now if you change the date in A1, the value of your SUMPRODUCT cell should change accordingly.
As a starter I recommend using Tables - it's much easier to read and maintain your data: Insert-->Table.
e.g.
Here I have "Table1", with the Date column formatted as a Short Date.
Name Date Quantity
Alpha 17-Mar-16 1
Beta 15-Feb-16 2
Charlie 11-Mar-16 3
Dog 11-Feb-16 4
Echo 9-Feb-16 4
Foo 6-Jan-16 5
Then in a separate row/cell, you can input a formula to sum the quantity column where the data is from 1st Feb onwards.
Here I've used a different date format, but Excel is fine with it.
Feb Onwards Total: 14 =SUMIFS(Table1[Quantity],Table1[Date],">=01-Feb-16")
Feb Only Total: 10 =SUMIFS(Table1[Quantity],Table1[Date],">=01-Feb-16", Table1[Date],"<29-Feb-16")
Try something like this:
=SUMPRODUCT((INT(GLTB!$E$3:$E$26522)=INT(GLTB!$A$1))*(ROUNDDOWN(GLTB!$A$3:$A$26522,2)=2.21)*(GLTB!$D$3:$D$26522))
If this Returns and error, then one of two things:
your dates are not true dates but text that look like dates.
your have errors in your cells in some of the columns.
My problem is the following...
I have a little aeroplane and I need to track the hours. I have to track the hours by sectors and not the total of the day (that's why sometimes I have 2 or 3 on the same day).
Now this is the problem... On column C I need to SUM the hours of the last 7 days. And any given 7 days, not just last week. To do it manually is quite easy... the problem is that I need a formula as my records are quite large...
Here with a small example (let's say that there was NO HOURS before 15/01/2009)...
COLUMN A-------COLUMN B-------COLUMN C
DATE--------------HOURS-------HOURS LAST 7 DAYS
15/01/2009-------01:00-------01:00
15/01/2009-------02:15-------03:15
16/01/2009-------01:15-------04:30
17/01/2009-------01:30-------06:00
18/01/2009-------01:30-------07:30
18/01/2009-------01:00-------08:30
18/01/2009-------02:00-------10:30
19/01/2009-------02:30-------13:00
19/01/2009-------03:00-------16:00
20/01/2009-------////////--------16:00
21/01/2009-------01:00-------17:00
22/01/2009-------01:30-------15:15
23/01/2009-------02:00-------16:00
I've been fighting for the last weeks trying to figure out a formula but no luck... any suggestions?
Thanks
Another solution that basically does much the same as the earlier offered solutions:
In C1, enter the following formula:
{=SUM(IF(($A$1:$A1>=($A1-6))*($A$1:$A1<=$A1), $B$1:$B1, 0))}
And then just drag the formula down.
If you're not familiar with array formulas, the {} outer brackets just indicate that the formula is an array formula. To get it to execute correctly, you need to copy the part inside the {} brackets into the formula bar, and then hit Ctrl+Shift+Enter to indicate that it's an array formula.
First thing is to get the begin date, which would be the following function:
=Now() - 7
If you renamed that cell to "WeekBegin", then you could use the following formula to calculate the total hours:
=SUMIF(A:A,">=" & WeekBegin,B:B)
Notice that I used column references; this was to both simplify the formula, but also allow you to add new data to the end of the range easily. You will need to take care that your WeekBegin cell is not in that column A or column B, otherwise you'll get a circular reference warning.
If you planned to have numeric data above or below your input range, you would need to explicitly call out the sum and criteria ranges as follows:
=SUMIF(A2:A14,">=" & WeekBegin,B2:B14)
Additionally, you may find that your result comes up initially as a decimal. That's Excel's date serial format, so you may need to format your result as time.
Hope that helps!
[Edit: On second pass, if you're looking to sum a range based on a from and to date (so any 7 days as you seem to imply in your post), look for the previous poster's note, i.e.:
=SUM(B:B) - SUMIF(A:A, "<="& BeginDate, B:B) - SUMIF(A:A, ">"& EndDate, B:B)
A more elegant solution is offered in Excel 2007 using the SumIFS() function:
=SUMIFS(B:B, A:A, ">=" & FromDate,A:A, "<" & ToDate)
Note that the arguments for SUMIFS are in a different order than the standard SUMIF.
Happy Summing!]
Here's the data in better format if someone wants to try:
15-Jan-2009 01:00
15-Jan-2009 02:15
16-Jan-2009 01:15
17-Jan-2009 01:30
18-Jan-2009 01:30
18-Jan-2009 01:10
18-Jan-2009 02:00
19-Jan-2009 02:30
19-Jan-2009 03:00
20-Jan-2009
21-Jan-2009 01:00
22-Jan-2009 01:30
23-Jan-2009 02:00
I got the function:
=SUM($B$1:$B$13)-SUMIF($A$1:$A$13, "<="& (A1- 7), $B$1:$B$13) - SUMIF($A$1:$A$13, ">"& (A1), $B$1:$B$13)
This was based on Sum of named ranges conditional to date?.
The idea is to first compute the total sum: SUM($B$1:$B$13)
then subtract any values that happened older than 7 days ago: SUMIF($A$1:$A$13, "<="& (A1- 7), $B$1:$B$13)
then subtract any values that happened in the future: SUMIF($A$1:$A$13, ">"& (A1), $B$1:$B$13)
The point is to use SUMIF function, which "adds the cells specified by a given criteria."
