Background: In the formulas below, I am trying to find any number that has the sequential pattern of +1. Example: 1011 (after 10, comes 11) =(FirstTwo+1=11)=Last 2.
Current Formulas:
A1 =ARRAYFORMULA(ROW(1000:1011)) //List numbers from 1000 to 1011.
B1 =ARRAYFORMULA(LEFT(A1:A,2)) //Only retrieve the first 2 digits.
C1 =ARRAYFORMULA(RIGHT(A1:A,2)) //Only retrieve the last 2 digits.
D1 =ARRAYFORMULA(if((B1:B12+1=C1:C12),TRUE,FALSE)) // If first 2 digits +1 = last 2 digits, TRUE.
Expected Outcome: D12 = TRUE
Actual Outcome: D12 = FALSE
My only found solution (not a good one)
Delete formula in C1.
Manually type each number in column C (resulting in C12 containing "11")
And now the array formula works for D1, and correctly applied TRUE in D12.
Why cant I achieve the same results using the formula in C1?
The problem is that the output data type is text and not an integer. You can test it by using the function type(). Reference document link.
You can fix it by multiplying the outputs by 1. Eg.:
B1: =ARRAYFORMULA(LEFT(A1:A,2)*1)
C1: =ARRAYFORMULA(RIGHT(A1:A,2)*1)

Suppose my excel sheet looks like this:
Name
Houses
Cars owned
column D
John
3
3
=A&MAX(30,3)
Harry
2
4
..
Vik
5
1
..
..
p
k
..
...
q
n
..
In column D, I want to return the row in column A that corresponds to the larger of the two values in cells B2 and C2. So in cell D2, I would want to return "Vik" because the larger of the two values in B2 (3) and C2 (3) is 3. And the value in cell A3 is Vik.
So in order to arrive at my result, I would input something like ="A"&MAX(B2,C2) in D2.
But suppose my formula was a lot more complex and with different data.
=IFERROR(ArrayFormula(ADDRESS(MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""),,IF($A$1:$D6=B7,COLUMN($A$1:$D6)),"")),MAX(IF($A$1:$D6=B7,COLUMN($A$1:$D6),"")))),"")
and I wanted the result of the first chunk of the formula (from ADDRESS() onwards)
MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),"") (which is 3, say) to be the row number that is input into
MAX(IF($A$3:$D3=B7,COLUMN($A$1:$D6),"")) for the range inside the IF condition.
(notice how $A$1:$D6 changed to $A$3:$D6)
So, going by the tabular example above, I would simply input MAX(IF("$A$"&MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""):$D6=B7,COLUMN($A$1:$D6),"")) and that should do the trick. Except it doesn't and I get a formula parse error which I cannot resolve.
Here is the specific excel sheet I'm working on: https://docs.google.com/spreadsheets/d/12U8U7Jp4FscobIvgr4_sADJB_oSdIHrboCk02cxF_u0/edit?usp=sharing
Can anyone see what I'm doing wrong? The solution, I think, should be simple enough but I can't seem to figure it out.
Sorry if it's a bit long but I've been struggling with this for a while now.
I hope this formula will help
=ARRAYFORMULA(IFNA(VLOOKUP(QUERY(TRANSPOSE(QUERY(TRANSPOSE(B2:C6);"select "&JOIN(",";"max(Col"&row(B2:C6)-1&")")));"select Col2+1 label Col2+1''");{row(A:A)\A:A};2;False)))
Solved using the indirect function and ampersand concatenation.
New function would be: =IFERROR(ArrayFormula(ADDRESS(MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""),,IF($A$1:$D6=B7,COLUMN($A$1:$D6),""))),MAX(IF(INDIRECT("$A$"&(MAX(index(IF($A$1:$D6=B7,ROW($A$1:$D6),""))))):$D6=B7,COLUMN($A$1:$D6),"")))),"")
I'm trying to write a formula that gives a running count of Issues for a given day. In other words: the output should enumerate each Issue for a given date (returning blank if Issue is blank), and then start again at 1 for the first issue in a subsequent date.
I've hard-coded the expected outputs in the "desired output" column (column I):
Sample dataset is in this sheet. Key pieces:
Column B contains the date
Column E contains the T-shirt size severity of each Issue
Column F contains a numerical translation of column E
Column G contains a binary output of whether there was an Issue
In my attempt (column J), I've gotten close using
=ArrayFormula(MMULT((ROW($B3:$B)>=TRANSPOSE(ROW($B3:$B))) * EXACT($B3:$B,TRANSPOSE($B3:$B))^1, ($G3:$G)^1))
...but it's not quite what I want, as:
this repeats values instead of giving blanks (e.g. row 8, 11)
this gives 0s instead of giving blanks (e.g. row 3, 4)
See Validation (column L).
Any ideas on how to get to what I'm looking for?
Just wrap your formula in the IF function
=ArrayFormula(IF(F3:F="",,YOUR.....FORMULA))
In other words
=ArrayFormula(IF(F3:F="",,
MMULT((ROW($B3:$B)>=TRANSPOSE(ROW($B3:$B))) * EXACT($B3:$B,TRANSPOSE($B3:$B))^1, ($G3:$G)^1)
))
I'm trying to CONCATENATE two cells in order to compare the results so that I can search by them, however the values of the two CONCATENATE outputs are different as one inputs is coming from the another formula.
Screen shots attached
I'm basically trying to compare the start time and channel number from A and B, with the data from G and H, so that I can update D with the relevant information in F (in the same format as A).
I first convert the EPOC time to human time readable, but when i try and CONCATENATE with the channel number, I get a different value to when i do that with A and B.
formula for c2 =CONCATENATE(A2,B2)
formula for i2 =G2/86400000+date(1970,1,1)
formula for k2 =CONCATENATE(G2,H2)
As you can see, the values for c2 and k2 are different event though a2 and i2 are the same (looking).
I've tried using CELL, INDEX, and INDIRECT but just can't seem to get it right, and I've tried various formatting options
Hopefully i've explained this right. Any solution welcome
raw data csv here START ,CHANNEL,concat,end?,,EndDateTime epoc,startDateTime epoc,channel,converted start,converted end,concat
12:58:00 AM,10,,,,1520391600000,1520382480000,7,,,
12:28:00 AM,7,,,,1520395200000,1520384280000,10,,,
So you have a couple of issues here.
CONCATENATE(A2,B2) will never equal CONCATENATE(I2,H2) because the values in A2 (12:58) and B2 (10) do not equal the values in I2 (12:28) and H2 (7). I think you meant to compare A2,B2 to I3,H3
A2 (12:58) does not equal I3 (12:58). You'll see this for yourself if you convert both to the date or number formats. The date value of A2 is 12/30/1899, the default when you enter only a time in the cell. The date value of I3 is 3/7/2018, because you converted the exact date and time from the EPOCH value.
For the two concatenations to equal each other, you need to resolve the issues above. You can do this by adding a date to column A's values.
On another note, I think there are better ways of populating column D based on the data in column F. A simple Vlookup should do the trick, once you resolve issue #2 above.
I'm new to Sheets and I don't know any terminology yet so I wasn't sure how to look this up.
If I have:
A1[=SUM(B1:1)]
How do I automatically copy that to A2 so that:
A2[=SUM(B2:2)]
And the same thing continues either indefinitely or until I declare a stopping point?
First of all, if you simply copy-paste the formula from A1 to A2 (or several cells below), it will automatically change as you want. This is how relative references work.
But it's also possible to get all the sums with one formula.
The following formula, entered in A1, will create sums of the first seven row in column A. To change the number of rows summed, replace 7 in B1:7 with another number.
=arrayformula(mmult(B1:7 + 0, transpose(B1:1 * 0 + 1)))
Explanation:
B1:7 + 0 coerces the entries to numbers (so that blank cells become 0).
transpose(B1:1 * 0 + 1) creates a column vector of 1s of suitable size.
matrix multiplication mmult by a column of 1s amounts to summing each row.
the wrapper arrayformula indicates that the operations are to be done on arrays.
Given a spreadsheet with two columns, say A and B, each containing n values under it, all text; is there a formula that allows me to fill just one cell containing the amount of equal values in columns A and B?
Example:
A B
-----
1 M M
2 L M
3 L L
4 M M
5 M L
-----
3
Since columns A and B both contain an M in rows 1 and 4, and an L in row 3, the result is (i.e. 2+1).
A simple solution is to use QUERY function in google spreadsheet:
=SUM(QUERY(A1:B5, "Select 1 where A = B"))
Or using SUMPRODUCT:
=ARRAYFORMULA(SUM(((A:A)=(B:B)) * (1) ))
One of possible solution will be to add the following formula in column C: =N(EXACT(A1,B1)),
copy it throughout the column down to the last row and then sum up the column C values using =SUM(C1:C5).
Here we go:
=IF(EQ(LEFT(A0, 1), "A"),
SUM(ARRAYFORMULA(N(EXACT(TRANSPOSE(A1:A5), TRANSPOSE(B1:B5))))),
"")
Reading: if the value in row 0 (it doesn't exist, but my example above does ;) ) is equal to the text "A", take the sum of an array N, otherwise put in an empty string. ("")
Array N is build by taking the transpose of columns A and B. (Turning them, so they look like a row) and comparing the values. (Burnash gave me the options "N" and "EXACT") The formula N transforms this into a 1 or 0.
Copy paste the formula in an entire row and what do you know... It worked! That was hellish for something so trivial.
Thanks anyway.
