For example I have a cell:
A
B
B
A
C
I want to have a summary of total count of each character:
A 2
B 2
C 1
How can I do this in Excel?
Insert > PivotTable
Select your column as the row field and as the value field. Change the value field calculation from sum to count if it defaults to sum.

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.
It's possible use Rank like Subtotals, that only use de showing data?.
If I filter data by a column, I want than Rank function only use these datas
Example
A B C The column C its Rank of column B
a 5 3
b 9 1
a 2 4
c 7 2
Now if I apply a filter in column A for value 'a'
A B C I want the rank recalculate with this new data
a 5 1 --> column C change from value 3 to value 1
a 2 2 --> column C change from value 4 to value 2
Thanks
You cannot do it by using RANK() formula, but you can create customizable rank formula. For this, You should add column at the and of table to indicate the row visibility, and put this formula into this column:
=(AGGREGATE(3;5;B2)>0)+0
Then put this formula into column C:
=SUMPRODUCT(($B$2:$B$9<B2)*($E$2:$E$9=1))+1
To check real example, download my sample file
I have the table in Excel:
In column C (Sum) I want to get sum this way:
If in column A or B value is 1 then take Amount 48 and multiply by Multiplier (1) = 2.
If in column A or B value is 0 then take Amount 48 and multiply by Multiplier (0) = 1,5.
Then K1 and K2 summed.
So for row 2 the result in column C will be: 48*2 + 48*2 = 192.
For row 5 the result in column C will be: 48*1,5 + 48*2 = 168.
Is it possible to automate this process using Excel formula for C column (inspite of number of columns)?
Or you could use Countif (no shorter though)
=COUNTIF(A2:D2,0)*I$2*I$1+COUNTIF(A2:D2,1)*I$3*I$1
Use Ctrl+Alt+Enter when entering (since it's an array formula)
EDIT: I'm not great with formulas, so there is I'm sure a shorter alernative...
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:
