Excel Sequential Numbering Based On Cell Value - excel

I need to generate a sequential number in col C based on the value in col B. The number needs to follow the text System and each time the sequence number in col B resets, I need the numbering to reset but start at the next nearest base number, as shown below
Example data...
A ¦ B ¦ C
1 1 End Item
2 2 System10
3 3 System11
4 3 System12
5 2 System20
6 3 System21
7 3 System22
8 2 System30
9 3 System31
I have tried the following formula =IF(B1=B2, "System" & C1+1, "System" & 1)
However this doesn't give me the numbers starting at 10.
Any help would be greatly appreciated.

As a first cut at this, you could try:
=IF(C1="End Item","System10",IF(B2>=B1,"System"&RIGHT(C1,LEN(C1)-6)+1,"System"&ROUNDUP(RIGHT(C1,LEN(C1)-6),-1)))
This does allow for numbers of more than two digits, but doesn't increase to the next multiple of ten if the current number is an exact multiple of ten.
One way of getting round this would be to add a small increment:
=IF(C1="End Item","System10",IF(B2>=B1,"System"&RIGHT(C1,LEN(C1)-6)+1,"System"&ROUNDUP(RIGHT(C1,LEN(C1)-6)+0.1,-1)))

Retrieve column 4 from Column 2 and 3 which contains minimum and maximum conditions along with Column 1 which is a separate value?

Hello I have a table shown below where I have letters in column 1, and min and max ranges for column 2 and 3. I am trying to retrieve the final number in column 4.
I know I can use a VLOOKUP and set the range as TRUE to get the last column. However, how would I factor in multiple columns/criteria to find match the correct range with the correct letter.
For example, I can would like to get value 4 from the last column. I would have to match with "B" and it would be between 0 and $50,000.
A 0 $50,000 1
A $50,001 $100,000 2
A $100,001 $250,000 3
B 0 $50,000 4
B $50,001 $100,000 5
B $100,001 $250,000 6
C 0 $50,000 7
C $50,001 $100,000 8
C $100,001 $250,000 9
Thank you!
Two ways:
If the pattern is the same as to the breaks of the dollar amounts then use this:
=INDEX(D:D,MATCH(G1,A:A,0)+MATCH(H1,$B$1:$B$3)-1)
Where MATCH(G1,A:A,0) returns the first row where the ID is located and MATCH(H1,$B$1:$B$3) finds the relative location of the price in the first pattern. Change $B$1:$B$3 to encompass the whole pattern.
If the patterns are different then you can use this:
=SUMIFS(D:D,A:A,G1,B:B,"<=" & H1,C:C,">=" & H1)
One more for the future when Microsoft releases FILTER():
=FILTER(D:D,(A:A=G1)*(B:B<=H1)*(C:C>=H1))
This is entered normally and does not matter the pattern.

Excel: Count until, then repeat?

I have a list of numbers which are either 1's or 2's. What I'd like to do is count how many 1's there are before a 2 appears, and then keep repeating this down the list (i'm trying to find the average number of 1's between each 2).
What would be the best way of doing this considering I've got over 10,000 rows? (i.e. too many to do manually)
The average number of 1's between each number 2, is the same as the ratio between the number 1 and the number 2.
Example:
1
1
2
1
1
1
1
2
1
1
2
1
1
2
Contains 10 ones and 4 twos.
Or there are five groups of ones, with the following counts: 2, 4, 2, 2
Either way, it will give you and average of 2.5 (10/4 = 2.5)
Note: You have to make a design choice, regarding how to handle beginnings and ends. If you had another one, after the last two, how should it be handled?
You can use the formula as shown in the screenshot below:
Note that the formula in the first row is different.
B C
=IF(A2=1,B1,B1+1) =COUNTIF(B:B,B2)
=IF(A3=1,B2,B2+1) =IFERROR(IF(A4=2,COUNTIF(B:B,B4),"")-1,"")
Then to get the average use:
=AVERAGEIF(C:C,"<>"&0)
Noceo's solution as a formula:
=COUNTIF(A:A,1)/COUNTIF(A:A,2)
The output of all the above:

Compare multiple data from rows

I'm looking for a way to compare multiple rows with data to each other, trying to find the best possible match. Each number in every column must be an approximately match the other numbers in the same column.
Example:
Customer #1: 1 5 10 9 7 7 8 2 3
Customer #2: 10 5 9 3 5 7 4 3 2
Customer #3: 1 4 10 9 8 7 6 2 2
Customer #4: 9 5 6 7 2 1 10 5 6
In this example customer #1 and #3 is quite similar, and I need to find a way to highlight or sort the rows so I can easily find the best match.
I've tried using conditional formatting to highlight the numbers that are the similar, but that is quite confusing, because the amount of data is quite big.
Any ideas of how I could solve this?
Thanks!
The following formula entered in (say) L1 and pulled down gives the best match with the current row based on the sum of the absolute differences between corresponding cells:-
=MIN(IF(ROW($C$1:$K$4)<>ROW(),(MMULT(ABS($C1:$K1-$C$1:$K$4),TRANSPOSE(COLUMN($C$1:$K$4))^0))))
It is an array formula and must be entered with CtrlShiftEnter.
You can then sort on column L to bring the customers with lowest similarity scores to the top or use conditional formatting to highlight rows with a certain similarity value.
EDIT
If you wanted to penalise large differences in individual columns more heavily than small differences to try and avoid pairs of customers which are fairly similar except for having some columns very different, you could try something like the square of the differences:-
=MIN(IF(ROW($C$1:$K$4)<>ROW(),(MMULT(($C1:$K1-$C$1:$K$4)^2,TRANSPOSE(COLUMN($C$1:$K$4))^0))))
then the scores for your test data would come out as 7,127,7,127.
I'm assuming you want to compare customers 2-4 with customer 1 and that you are comparing only within each column. In this case, you could implement a 'scoring system' using multiple IFs. For example,:
A B C D E
1 Customer 1 1 1 2
2 Customer 2 1 2 2
3 Customer 3 0 1 0
you could use in E2
=if(B2=$B$1,1,0)+if(C2=$C$1,1,0)+if(D2=$D$1,1,0)
This will return a 'score' of 1 when you have a match and a 'score' of 0 when you don't. It then adds up the scores and your highest value will be your best match. Copying down would then give
A B C D E
1 Customer 1 1 1 2
2 Customer 2 1 2 2 2
3 Customer 3 0 1 0 1
so customer 2 is the best match.

EXCEL - Comparing Two Columns - Removing Repeats

If two households share, they create a tie and this tie has a kinship rank that does not change, no matter how often two households share with each other.
KINSHIP RANK EXAMPLE
As you can see, it doesn't matter in which "direction" the tie happened whether it was household 5 who shared to household 3 or vice versa, the kinship rank is still 1
HH1 HH2 RANK
5 3 1
3 5 1
Therefore, I do not need every tie that occurs between two households, but only the first instance that a tie occurred between the two households.
So here is a sample list of many households who shared with each other, sometimes sharing resources with themselves, sharing only once, or sharing multiple times with the same household.
TWO HOUSEHOLD WITH REPEATED TIES
COL.A COL.B
ROW HH1 HH2
1 1 1
2 1 2
3 1 3
4 2 1
5 2 4
6 3 1
7 3 2
8 3 4
9 4 2
This is what I need it to look like:
TWO HOUSEHOLDS WITHOUT REPEATED TIES
COL.A COL.B
ROW HH1 HH2
1 1 1
2 1 2
3 1 3
4 2 4
5 3 2
6 3 4
What I have done
I wrote a simple command for placing the HH1 and HH2 information into the same cell:
=A1&"|"&B1
In the case of the second row, this looks like 1|2 inside cell C2
HH1 and HH2 are combined in column C so how will I be able to compare all of the households in column C to each other? Perhaps a highlighting rule if a repeat happens? Or in another column list if it is a delete or a keep?
Thank you for your assistance everyone.
I suggest a simple COUNTIFS to do the job like this:
=(COUNTIFS(A$1:A1,B2,B$1:B1,A2)+COUNTIFS(A$1:A1,A2,B$1:B1,B2))>0
starting in C2 and then copy down. It will show TRUE for each row which is within the range above it and false if not. Ich checks for both x/y and y/x (the order doesn't matter)
Now simply filter col C to only show rows with TRUE in it. Then simply select and delete it.
This also works with non numerical values like names.
If you still have any questions, just ask ;)
You also can wrap it up to get more informations like this:
=IF((COUNTIFS(A$1:A1,B2,B$1:B1,A2)+COUNTIFS(A$1:A1,A2,B$1:B1,B2)),"",COUNTIFS(A:A,B2,B:B,A2)+COUNTIFS(A:A,A2,B:B,B2))
For C2 and copy down. C1 gets:
=COUNTIFS(A:A,B2,B:B,A2)+COUNTIFS(A:A,A2,B:B,B2)
This will show you only at the first occurrence how many times it is within the whole range.
All done by phone, may contain errors
Use =((A1*B1)/(A1+B1))*((A1*B1)+(A1+B1)) to create unique identifiers. Then use Remove Duplicates in the Data Tools Pane of the Data Tab to remove all rows containing duplicates. Or, alternatively, use something like =IF(IFNA(MATCH(A2,A$1:A1,0),TRUE())=TRUE,"First Share","") dragged and dropped from row 2 to identify First Shares.

rearranging data in excel

I'm not sure how to ask this question without illustrating it, so here goes:
I have results from a test which has tested peoples attitudes (scores 1-5) to different voices on a 16 different scales. The data set looks like this (where P1,P2,P3 are participants, A, B, C are voices)
Aformal Apleasant Acool Bformal etc
P1 2 3 1 4
P2 5 4 2 4
P3 1 2 4 3
However, I want to rearrange my data to look like this:
formal pleasant cool
P1A 3 3 5
P1B 2 1 6
P1C etc
P1D
This would mean a lot more rows (multiple rows per participant), and a lot fewer columns. Is it doable without having to manually reenter all the scores in a new excel file?
Sure, no problem. I just hacked this solution:
L M N O P Q
person# voice# formal pleasant cool
1 1 P1A 2 3 1
1 2 P1B 4 5 2
1 3 P1C 9 9 9
2 1 P2A 5 4 2
2 2 P2B 4 4 1
2 3 P2C 9 9 9
3 1 P3A 1 2 4
3 2 P3B 3 3 2
3 3 P3C 9 9 9
Basically, in columns L and M, I made two columns with index numbers. Voice numbers go from 1 to 3 and repeat every 3 rows because there are nv=3 voices (increase this if you have voices F, G, H...). Person numbers are also repeated for 3 rows each, because there are nv=3 voices.
To make the row headers (P1A, etc.), I used this formula: ="P" & L2 & CHAR(64+M2) at P1A and copied down.
To make the new table of values, I used this formula: =OFFSET(B$2,$L2-1,($M2-1)*3) at P1A-formal, and copied down and across. Note that B$2 corresponds to the cell address for P1-Aformal in the original table of values (your example).
I've used this indexing trick I don't know how many times to quickly rearrange tables of data inherited from other people.
EDIT: Note that the index columns are also made (semi)automatically using a formula. The first nv=3 rows are made manually, and then subsequent rows refer to them. For example, the formula in L5 is =L2+1 and the formula in M5 is =M2. Both are copied down to the end of the table.
