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 generally ask Python or VBA questions, but this has been annoying me for the past 4.5 hours and i need it to finish a macros and i'm just getting div/0 error.
In excel i have five columns:
1. Date when the item entered the queue (A)
2. time when the item entered the queue (B)
3. Date when the item left the queue (C)
4. time when the item left the queue (D)
5. time the item was in the queue (E)
I need the average of time of the items that entered and left the queue between 16:00 yesterday and 16:00 today. Also for it to ignore numbers < than 1 (because if an item has been there for over 24 hours the default value is negative).
I tried tried this and no results :(
=AVERAGEIFS(E1:E4,A1:A4,"=today()-1",B1:B4,">16:00",C1:C4,"=today()",D1:D4,"<16:00")
Any ideas would be appreciated! Thanks in advance :)
Your formula is saying this:
=AVERAGEIFS(E1:E4,A1:A4,"=today()-1",B1:B4,">16:00",C1:C4,"=today()",D1:D4,"<16:00")
Take the average of E1:E4 if...
A1:A4 are equivalent to the string "=today()-1"
B1:B4 are equivalent to the string ">16:00"
C1:C4 are equivalent to the string "=today()"
D1:D4 are equivalent to the string ">16:00"
What you want it to say is:
Take the average of E1:E4 if...
A1:A4 are equivalent to the result of the formula =today()-1
B1:B4 are less than 16 hours
C1:C4 are equivalent to the result of the formula =today()
D1:D4 are less than 16 hours
Let's tackle 2 and 4 first.
In Excel, 1 day (24 hours) = 1. Times are stored as decimal values as a percentage of a day:
1 day = 1
1 day = 24 hours
1 hour = 1 / 24
16 hours = 16/24 = 2/3
So instead of B1:B4,">16:00" you should rewrite the formula as:
B1:B4,">"&2/3
The & concatenates the greater than sign, and 2/3 will give the decimal value equivalent to 16:00. In the end you will get a string equal to ">.6666666666"
(You can also just use B1:B4,">.6666666666666" if you'd like)
For items 1 and 3, you don't need to use quotes at all. So instead of A1:A4,"=today()-1" you can just use the following:
A1:A4,today()-1
C1:C4,today()
Putting this all together, the following formula should work:
=AVERAGEIFS(E1:E4,A1:A4,today()-1,B1:B4,">"&2/3,C1:C4,today(),D1:D4,"<"&2/3)
If you are looking for "items that entered and left the queue between 16:00 yesterday and 16:00 today" isn't it possible that some of those entered the queue today (or left the queue yesterday)? If so you would need to check for items that entered today as well, surely? To do that is difficult with AVERAGEIFS function - it might be easier to use an "array formula" like this:
=AVERAGE(IF(A1:A4+B1:B4>=TODAY()-1/3,IF(C1:C4+D1:D4<TODAY()+2/3,E1:E4)))
confirmed with CTRL+SHIFT+ENTER
I'm assuming that the formula doesn't have to explicitly deal with your negative values because those will only occur for items which have been there for more than 24 hours and the IF functions will exclude those anyway...
If you want to do the same with AVERAGEIFS you'd need to create two additional columns with the entry/exit dates/times added, e.g. if column G is the sum of columns A and B and column H is the sum of columns C and D you could use this version
=AVERAGEIFS(E1:E4,G1:G4,">="&TODAY()-1/3,H1:H4,"<"&TODAY()+2/3)
Note that I used >= and < deliberately to avoid double-counting/non-counting across several days
