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.
Column A Column B
13-06-2013 10:50
13-06-2013 11:30
13-06-2013 12:40
14-06-2013 10:30
I need to find the values which are before a particular entry date and time.
For example, say I want to find the values in the example table above that are immediately prior to the values "13-06-2013" and "12:30".
Since 12:30 is not in column B, how do I find the values I am looking for? The answer should be 13-06-2013 and 11:30.
C7 =VLOOKUP(A7&B7,A1:C4,3,TRUE)
Here A1 = B1&C1
A B C
1 414380.451388888888889 13-06-2013 10:50
2 414380.479166666666667 13-06-2013 11:30
3 414380.527777777777778 13-06-2013 12:40
4 414390.4375 14-06-2013 10:30
5
6 Enter date Enter Time Returned Time
7 13-06-2013 12:30 11:30:00
Setting 'range_lookup' as 'True' adds the flexibility to return the closest approximate value if the exact value is not available.
I think you're looking for something like this. using index and match.
I didn't take into account the date for now. but this gives you an example.
You can compare date strings with operators like > or < etc. Concatenate your values in columns A & B, compare to the desired date/time string. In cell C1 put the following formula, and then drag down:
="13-06-2013 12:30"<A1&" "&B1
or more specifically, depending on which "12:30" you want (AM or PM), ="13-06-2013 12:30AM" or ="13-06-2013 12:30PM"
Your data in column B may default to AM unless otherwise specified/imported differently, so you may need to tweak the data or to account for this.
Here is another approach to answering your question that uses a combination of MATCH, INDEX, and array operations to provide a compact formula solution that does not rely on helper columns.
I'll assume that your two columns of dates and times are in cells A2:B5, and the two date and time values that you want to look up are in cells A9:A10. Then the following two formulas will return what you require, the latest date and time values in your data that are less than or equal to the date and time that you are looking up. (The dollar signs in the formulas are hard on the eyes, but they are important if you will need to copy the formulas to other locations; for clarity, I omit them in the discussion that follows.)
DATE: =INDEX($A$2:$B$5,MATCH(A9+A10,$A$2:$A$5+$B$2:$B$5,1),1) --> 13-06-2013
TIME: =INDEX($A$2:$B$5,MATCH(A9+A10,$A$2:$A$5+$B$2:$B$5,1),2) --> 11:30 AM
These are array formulas and need to be entered with the Control-Shift-Enter key combination. (Of course, only the bits starting with the equal (=) sign and ending with the last parenthesis need to be entered into the worksheet.)
Things to consider:
The formulas assume that your data are valid Excel date and time values. Excel date values are whole numbers that count the number of days that have elapsed since January 1, 1900; Excel time values are decimal amounts between 0 and 1 that represent the fraction of 24 hours that a particular time represents. While your example data don't display AM or PM, I assume that their underlying values do have that information.
If your values are text (having been imported from another source, for instance), you should convert them to date/time values, if lucky, using only Excel's DATEVALUE and TIMEVALUE functions; if not so lucky, using some combination of Excel's string manipulation functions as well. (The values could be kept as strings, but you would almost certainly need to massage them so they would compare correctly "alphabetically" - much easier just to deal with Excel date/time values.)
If they are not already, your dates and times will need to be sorted from smallest to largest. (Your sample looks like they are sorted, and the formulas assume as much.)
How the formulas work
The basic idea behind the formulas is two-fold: first find the row in your data that holds the latest (largest) date and time that is still less than or equal to the date and time you are looking up. That row information can then be used to fetch the final result from each column of the data range (one for date and one for time).
Since both date and time figure in to what point in time is latest, the date and time components of both the value to be looked up and the values that will be searched must be combined somehow.
This can be achieved by simply adding the dates and times together. This does nothing more than what Excel does: an Excel date/time value has an integer part (the number of days since 1/1/1900) and a decimal part (the fraction of 24 hours that a particular time represents).
What is neat here is that the adding up of the dates and times - and the lookup of the particular date and time - can be done all at once, on the fly.
Take a look at the MATCH: The cells that contain the date and time to be looked up - A9 and A10 - are added together, and then this sum is matched against the sum of the date column (A2:A5) and the time column (B2:B5) - an operation that is possible of Excel's array arithmetic capabilities. The match returns a value of 2, indicating correctly that the date and time that fill your requirements are in row 2 of the data table.
DATE/TIME MATCH: = MATCH( A9+A10, A2:A5 + B2:B5, 1 ) --> 2
The 1 that is the final argument to the MATCH function is an instruction that the match results be calculated to be less than or equal to the value to be looked. It is the default value and is often omitted, or replaced with another value (for example, using a value of 0 will produce an exact match, if there is one).
(For readability, I've removed the dollar signs that are in the full formula; these anchor a range so that it remains the same even if the formula is copied to another location.)
Having figured out the row to look in, the rest of the formula is straightforward. The INDEX function returns the value in a data range that is at the intersection of a specified row and column. So, for the date in question, the formula reduces to:
DATE FETCH: = INDEX( A2:B5, 2, 1) --> 13-06-2013
In other words, INDEX is to return the value in the second row and first column of the data range A2:B5.
The formula for the time proceeds in exactly the same fashion, with the only difference that the value is returned from the second column of the data range.
I am analysing library statistics relating to loans made by particular user categories. The loan data forms the named range LoansToApril2013. Excel 2007 is quite happy for me to use an index range as the sum range in a SUMIF:
=SUMIF(INDEX(LoansToApril2013,0,3),10,INDEX(LoansToApril2013,0,4):INDEX(LoansToApril2013,0,6))
Here 10 indicates a specific user category, and this sums loans made to that group from three columns. By "index range" I'm referring to the
INDEX(LoansToApril2013,0,4):INDEX(LoansToApril2013,0,6)
sum_range value.
However, if I switch to using a SUMIFS to add further criteria, Excel returns a #VALUE error if an index range is used. It will only accept a single index.
=SUMIFS(INDEX(LoansToApril2013,0,4),INDEX(LoansToApril2013,0,3),1,INDEX(LoansToApril2013,0,1),"PTFBL")
works fine
=SUMIFS(INDEX(LoansToApril2013,0,4):INDEX(LoansToApril2013,0,6),INDEX(LoansToApril2013,0,3),1,INDEX(LoansToApril2013,0,1),"PTFBL")
returns #value, and I'm not sure why.
Interestingly,
=SUMIFS(INDEX(LoansToApril2013,0,4):INDEX(LoansToApril2013,0,4),INDEX(LoansToApril2013,0,3),1,INDEX(LoansToApril2013,0,1),"PTFBL")
is also accepted and returns the same as the first one with a single index.
I haven't been able to find any documentation or comments relating to this. Does anyone know if there is an alternative structure that would allow SUMIFS to conditionally sum index values from three columns? I'd rather not use three separate formulae and add them together, though it's possible.
The sumifs formula is modelled after an array formula and comparisons in the sumifs need to be the same size, the last one mimics a single column in the LoansToApril2013 array column 4:4 is column 4.
The second to bottom one is 3 columns wide and the comparison columns are 1 column wide causing the error.
sumifs can't do that, but sumproduct can
Example:
X 1 1 1
Y 2 2 2
Z 3 3 3
starting in A1
the formula =SUMPRODUCT((A1:A3="X")*B1:D3) gives the answer 3, and altering the value X in the formula to Y or Z changes the returned value to the appropriate sum of the lines.
Note that this will not work if you have text in the area - it will return #VALUE!
If you can't avoid the text, then you need an array formula. Using the same example, the formula would be =SUM(IF(A1:A3="X",B1:D3)), and to enter it as an array formula, you need to use CTRL+SHIFT+ENTER to enter the formula - you should notice that excel puts { } around the formula. It treats any text as zero, so it will successfully add up the numbers it finds even if you have text in one of the boxes (e.g. change one of the 1's in the example to be blah and the total will be 2 - the formula will add the two remaining 1s in the line)
The two answers above and a bit of searching allowed me to find a formula that worked. I'll put it here for posterity, because questions with no final outcome are a pain for future readers.
=SUMPRODUCT( (INDEX(LoansToApril2013,0,3)=C4) * (INDEX(LoansToApril2013,0,1)="PTFBL") * INDEX(LoansToApril2013,0,4):INDEX(LoansToApril2013,0,6))
This totals up values in columns 4-6 of the LoansToApril2013 range, where the value in column 3 equals the value in C4 (a.k.a. "the cell to the left of this one with the formula") AND the value in column 1 is "PTFBL".
Despite appearances, it isn't multiplying anything by anything else. I found an explanation on this page, but basically the asterisks are adding criteria to the function. Note that criteria are enclosed in their own brackets, while the range isn't.
If you want to use names ranges you need to use INDIRECT for the Index commands.
I used that formula to check for conditions in two columns, and then SUM the results in a table which has 12 columns for the months (the column is chosen by a helper cell which is 1 to 12 [L4]).
So you can do if:
Dept (1 column name range [C6]) = Sales [D6];
Region (1 column name range [C3]) = USA [D3];
SUM figures in the 12 column monthly named range table [E7] for that 1 single month [L4] for those people/products/line item
Just copy the formula across your report page which has columns 1-12 for the months and you get a monthly summary report with 2 conditions.
=SUMPRODUCT( (INDEX(INDIRECT($C$6),0,1)=$D$6) * (INDEX(INDIRECT($C$3),0,1)=$D$3) * INDEX(INDIRECT($E7),0,L$4))
