Highlight duplicate cell values in different colours - excel

I'm using conditional formatting to highlight duplicate cells, but I have up to 5 instances of a duplicated value. How can I apply a separate colour to each duplicated cell?
So if I have 5 instances of ABC123, how can the first instance be red, the second green, the third blue, fourth yellow, fifth orange (or whatever colours)?

I take it this is in Excel 2007? In earlier versions you can only have three different conditions.
The way I'd do this is to introduce a 'helper' column, containing a formula which provides the count of duplicates up to that row number:
Say you have your list (including dupes) in range A1:A10, and in column B1:B10, a formula of the form =COUNTIF($A$1:A1,A1) through =COUNTIF($A$1:A10,A10), you'd have
A B
------------
1 4 1
2 2 1
3 4 2
4 3 1
5 1 1
6 2 2
7 4 3
8 2 3
9 2 4
10 1 2
I don't know your exact Conditional Formatting requirements, but you can now use 5 nested IF formulas to take account of not only the fact that something is a dupe (cell in B is >= 2), but also the count of the dupe.

How to create two columns that match all values from a third in excel or OpenOffice?

I have one column with 10 cells, every cell have a different value in it. How can I create two columns that have every cell matching with the other 9.
Example :
1
2
3
4
5
6
7
8
9
10
Become
1 2
1 3
1 4
1 5
......
2 1
2 3
2 4
2 5
.....
10 1
10 2
10 3
10 4
10 5
10 6
10 7
10 8
10 9
I am not sure I read the same question as others did. I think your example was merely that, an example, and that these first 10 cells could contain anything and you wanted every permutation that could result. While I think that the other answers might work for the specific situation you describe, they may not work if you had other data in those cells. Hence I am offering a variation which uses a similar technique to reference the cells indirectly. The permutations of 2 objects from a set of 10 unique objects would result in 90 objects (which is why the above technique from Tom Sharpe references 90).
Assuming that you have your 10 items in A1 through A10, I would put the following formula in B1 and copy it down through B90:
=INDIRECT("R"&QUOTIENT(ROW()-1,9)+1&"C1",FALSE)
Also, I would use this formula in C1 and copy it down through C90:
=INDIRECT("R"&MOD(ROW()-1,9)+1+((MOD(ROW()-1,9)+1)>=QUOTIENT(ROW()-1,9)+1)&"C1",FALSE)
The result should give you something like what is shown in the attached matching your example.
Likewise, it would show the permutations of any values you had in A1 through A10 as shown in the second attached picture with words instead of the numbers 1 through 10.
In Excel (without VBA or such like), one way:
In A1 and copied down to A100: =INT((ROW()+9)/10).
In B1 and copied down with Ctr to B10: 1.
Select B1:B10 and copy down with Ctrl to B100.
In C1 and copied down to C100: =A1=B1.
Select ColumnsA:B, Copy, Paste Special, Values.
Filter A:C ,select TRUE in ColumnC and delete all blue indexed (visible content) rows.
Delete ColumnC.
Or in A1:
=QUOTIENT(ROW()-1,9)+1
copied down to A90 just to be different.
Then in B1:
=MOD(ROW()-1,9)+1+((MOD(ROW()-1,9)+1)>=A1)
copied down to B90.

Dynamically change row number in excel

I got a file in excel that often changes the row number (My first column) whenever there is a insertion of data. However, there is multiple rows of data with the same row number.
Example:
1
1
2
3
3
3
Is there a way I can change them dynamically beside grouping the number together via Filter and change it manually?
Edited.

Better example. Sorry about the indentation.
I can propose a partial solution.
Set the value only in the first identical value and change only those unique values when a group of rows is inserted:
1 1
1 =A1
1 =A2
2 2
3 3
4 4
4 =A6
4 =A7
Otherwise, you do it from VBA to change all values when a new row is inserted.

Sum across columns based on 3 criteria

I'm trying to get a Sumif working across multiple rows.
For example, say my data source is below:
A B C
1 1 10 11
2 2 9 12
3 3 8 13
4 4 7 14
5 5 6 58
I want to sum from Columns A to C, in row 3. Output would be 24.
Ideally my criteria for the Horizontal Start, Horizontal End and Vertical would all be referenced in different cells which can be updated to get a new result depending on the criteria.
Is this possible so that the criteria cells can be updated and the formula will update accordingly?
Use a SUMIF, and betweem the logical criteria, simply use 3 criterias by seperating each with "&"'. This says that excel will sum if a happens, and b and c.

Summing a set of values based on cell content and row position

In the below table rows 2,3 and 4 have some details of a sporting event.
Range A2:C4 has a set of squad numbers and range D2:F4 has the details of who scored goals.
A B C D E F
1 Squad # Scorers
2 1 3 6 2 8 3
3 3 6 7 6 1
4 1 5 6 7 2 4
As an example squad # 6 has scored 8 goals based on the values equivalent position in the Squad section and relative to the Scorers range.
What formula will give me this total value and the equivalent total values for all squad numbers like the table below?
Some cells will be empty like F3.
1 9
3 14
5 2
6 8
7 0
A simple SUMPRODUCT function should take care of this.
=SUMPRODUCT($D$2:$F$4, --($A$2:$C$4=H2))
Fill down as necessary.
        
With only 3 games, the simplest way that I can see to do this would be to use 4 SUMIFS statements, as follows [assumes that your results data is in columns A & B, starting at row 5 and moving down; A5:A12 would hold the IDs for the different squads, and this formula would go in B5 and be copied down]:
=SUMIFS($D$2:$F$2,$A$2:$C$2,A5)+SUMIFS($D$3:$F$3,$A$3:$C$3,A5)+SUMIFS($D$4:$F$4,$A$4:$C$4,A5)
What it does is sum columns D:F, for row 1, row 2, and row 3, based on the fact that columns A:C for those rows match the appropriate squad ID.
This would be possible with an arguably shorter but more complex Array Formula, but with the data as you've presented it, I feel this is the clearest method.

Return list of matching rows

Sheet1
A B C D
1 2 3 4
2 4 5 6
3 3 5 6
4 7 3 1
5 4 6 7
Sheet 2
A B C D
1 4
2 1
3 1 3 4
4 1 2 5
5 2 3
6 2 3 5
7 4 5
Column A of Sheet 2 has a non repeating listing of all values in Sheet 1. I would like a forumla so Col B of Sheet 2 lists the value of Sheet 1 Col A for each row where the Sheet 2 Col A lookup value is found. Either giving me a comma sep list or putting the results in sheet 2 Col B,C,D,...
I came up with a solution, but it involves a handful of formulas, not just one. Hopefully, you will still find it useful.
Your Sheet2 would basically look like this:
Here are the formulas you need to enter:
B1: =IFERROR(SMALL($G4:$U4,COLUMN()-1),"") [drag down and across to D7]
G1: =IF(F2=$W2,F1+1,MAX(1,F1)) [drag across to U1]
G2: =IF(F2=$W2,1,F2+1) [drag across to U2]
G3: =INDEX(Sheet1!B$1:D$5,G1,G2) [drag across to U3]
G4: =IF(G$3=$F4,G$1,"") [drag down and across to U10]
What this does is organize the Sheet1 data into rows, where each row corresponds to a lookup value. Then, it grabs the smallest value, the second smallest value (if one exists), and third smallest value (if one exists) from each row.
This should be easy to scale to as large a spreadsheet as you need (as long as you don't run out of columns).
