I have 2 columns looking like this:
Column 1 Column 2
1 x
x 2
2 2
x x
1 2
I want to do two things;
For each row match (row n column 1 = row n column 2) it should mark cell n in column 1 green if there is a match and red if it is not.
It should create a sum cell where each match is worth 1 point, in this case column 1 should result in 2 points.
Is this even possible with excel and if so, how is it done?
For the first part of your question:
It should mark cell n in column 1 green if there is a match and red if it is not
You can do this using Conditional Formatting.
Ex:
Assume column A and column B, with the values starting in row 2.
The following conditional formatting would highlight column A values in green if they match the corresponding value in column B in the same row, otherwise red.
Highlight the values in column A, then apply this conditional formatting.
For the second part of your question
It should create a sum cell where each match is worth 1 point, in this case column 1 should result in 2 points
The following array formula will tally all the matches and show you how many there are:
=SUM(IF(A2:A6=B2:B6,1,0))
Assuming again that we are in columns A & B with your sample data.
Remember to commit this formula using Ctrl+Shift+Enter.
Per comment from andy holaday, here is another formula that will work:
=SUMPRODUCT(N(A2:A6=B2:B6))
or
=SUMPRODUCT(--(A2:A6=B2:B6))
These are not CSE formulas so you would not need Ctrl+Shift+Enter to commit them.

Suppose I have a simple dataset in Excel:
Column 1 Column 2
A 1
B 1
C 2
D 4
E 5
F 9
Now I want to mark the whole row with green color, if the value in column 2 is larger than 3. I apply a conditional format with the formula =$B2>3 applied on range =$A$1:$B$7 and it does not work:
One line where the value is 2 is marked green and one where it is 9 is not marked.
Now I want to mark the row, however only, if the value in column 2 is between 3 and 6. I apply the formula =AND(3<$B2;$B2<6) to the same range and it does not work:
Nothing is marked green.
Where is my mistake?
Update:
I now also tried =AND(3<$B1;$B1<6), but still nothing is marked green?
Change =$B2>3 to =$B1>3 which should work for you.
Your formula start range and apply start range must be same. Otherwise CF will highlight different cells.
Ok I have 2 excel columns
1st column A "Workstream", is a data list with three numbers as a dropdown. 1,2,3
2nd column B "ID", would like to auto-populate based on the selection made from the left adjacent cell + perform a lookup to get the MAX number in the current column and ADD by 1.
For Example:
Workstream
ID
1
W1-001
1
W1-002
1
W1-003
1
W1-004
2
W1-001
1
W1-005
2
W1-002
So when a user selects from the drop-down in column A then Column B auto-populates with something like this
="W"&A:1&"-"
However, in order to complete the value, it needs to do the following:
="W"&A:1&"-" Search for the Max Record in Column B that starts with 1 or whatever value was entered into Column A, then include the next number based on the MAX value selected in Column A
So in the above example, let's say I Enter "2" in column A, then the value that auto-populates in column B would be
| 2 | W2-003
or if I selected 1 from column A given where we left off then the value that would auto-populate in column B would be:
| 1 | W1-006
If I am understanding correctly and you want the format to be "W" followed by number of the workstream (as inferred from the text of your question) try:
="W"&A2&"-"&TEXT(COUNTIF(A$2:A2, B2), "000")
If instead you want the output exactly as shown in the picture you provided, it's even easier:
="W1-"&TEXT(COUNTIF(A$2:A2, B2), "000")
EDIT: You might consider pre-dragging the formula to all the rows that you think have the possibility of being impacted so that you don't have to drag the formula each time you add a row. In that case, try:
=IF(A2="","", "W"&A2&"-"&TEXT(COUNTIF(A$2:A2, B2), "000"))
I have an excel sheet in CSV that has 8 columns A-H and thousands of rows with values 0 or 1 depending on truth value.
I'm looking for the Excel function in which I can select rows where column A and B are true so that I can check another columns probability given A&B. IE P((A&B)|D) (where | means given).
I'm really new to excel and having difficulties finding how to only select rows that meet this criteria.
The following formula entered in I1 will return a 1 if both A1 and B1 are true.
=IF(AND($A1=1,$B1=1),1,0)
Copy it down or autofill to identify all rows where A and B are true.
The $ sign before A and B make the column references absolute meaning if you drag the formula to the right, the references to columns A and B will remain.
Because Excel implicitly interprets 0 = FALSE and 1 (or any other number) = TRUE the formula could be shortened to:
=IF(AND($A1,$B1),1,0)
The probability of C being 1 given that A and B are 1 can be calculated by counting all rows where A, B and C are all 1 and dividing by the number of rows where both A and B are 1:
=COUNTIFS($A:$A,"1",$B:$B,"1",C:C,"1")/COUNTIFS($A:$A,"1",$B:$B,"1")
Again, references to A and B are absolute, while C is relative so you can drag right to get probabilities for columns D to H.
COUNTIFS only counts the rows where all of the criteria are met and allows you to specify up to 127 range/criteria pairs.
EDIT
You could also use:
=AVERAGEIFS(C:C,$A:$A,1,$B:$B,1)
to get the probability.
I need to drag cells which equal values of columns which have a distance of for example 4 columns horizontally. Is there any way to add a number for example in column A to get column E?
Example:
A B C D E F G H I J K
1 2 2 3 4 1 5 6 9 1 2
I need the values only of columns A, E and I in other cells which are at the right of these cells without leaving empty cells and by dragging horizontally.
A wax to do this is to change the numbering of the columns from letters to numbers (file->options->formulas->work with formulas-> tick the first field Column Line).
Then the programming with numbers is easier than using commands to change the column letters in numbers and vice versa. To change the column letters into numbers can also be done with thefunction column. However the inverse function of this is a combination of functions and it is quite difficult to do.
I have a worksheet that has information like this:
a
a
b
c
c
c
How do I format it so that all of the rows that have a value of a in the first column are one color, then all the rows that have a value of b in the first column are a different color, etc. ?
Edit not from OP to add clarification from comment:
Everything is already sorted alphabetically, and will stay that way, and I want multiple colors.
Create a helper column with a formula like this;
=MOD(IF(A3=A2,0,1)+B2,2)
In this example column A is the column of sorted values to be grouped by, and column B is the helper column. The formula is entered on row 3. Set the first row of the helper column to the value 0 and the others to the formula. This will result in alternating values in the helper column for each group, ie;
a 0
a 0
b 1
c 0
c 0
c 0
d 1
d 1
e 0
You can then set conditional formatting based on the column value. If the value is 1 then highlight the row; if it is 0 do not highlight it. Or use alternating colors or whatever. You can reference any of the articles on the web that describe how to conditional format the entire row based on the value in the column.
IF(A3=A2,0,1) compares the current row (3) and prior row (2) returning a 1 or 0.
MOD( [...] +B2,2) accomplishes the alternation between 0 and 1 when the grouping column value changes.
I think you need a helper column, say B seeded with 1 in row1, and =IF(A1=A2,B1,B1+1) in B2 and copied down to suit. Then formulae of the kind below should suit for conditional formatting:
