In excel, how can we return true or false in a column based on comparing 2 columns in each cell. for an example
we have a table looks like this in excel
ROW
Column : A | B | C |
1 apple motor
2 pineapple train
3 car plane
4 motor durian
in the given example of the table above.
in column C , first row should return true followed by false. i know we can compare directly using
=if(b1=a4,TRUE,FALSE)
in the first column , this will return true . but i want compare each cell in column b to column a. i have tried this in excel but its returning false instead of true
=if(b1=a1:a4,True,false)
What approach should i use ?
You can use array formula with OR:
=OR(B1=A:A)
Array formula after editing is confirmed by pressing ctrl + shift + enter
Or if you don't want to use an array formula, use COUNTIF:
=COUNTIF(A:A,B1)>0

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$2:A2, B2), "000"))
Column A Has Text & Columns B, C & D contain numbers.
For Ex.)
A... …B C D
John 4 6 2
Dave 4 6 4
Mike 4 5 1
Bill 2 5 9
I would like a cell to return the name in column A that has the Largest Number in Column B. And if there are similar numbers, go to the next column and determine which is highest, and if that is tied go to the next column and so on.
Any help would be appreciated.
We can de-conflict ties.In E1 enter:
=B1 + C1/(10*MAX(C:C))+D1/(100*MAX(D:D))
and copy down. Then in another cell enter:
=INDEX(A:A,MATCH(MAX(E:E),E:E,0))
EDIT#1
This is only good for 3 columns of numbers, but it is very easy to add additional de-confliction terms if necessary:
=B1 + C1/(10*MAX(C:C))+D1/(100*MAX(D:D))+E1/(1000*MAX(E:E))
For an expandable number of rows/columns, use a helper row with the same number of columns as number columns in your data. The formulas below reference the following image (the data are in A1:G7):
B9-->=MAX(B1:B7)
C9 (fill over the remaining columns to G9)-->
=MAX(IF(MMULT(--($B1:B7=$B9:B9),--(ROW(INDIRECT("1:"&COLUMNS($B9:B9)))>0))=COLUMNS($B9:B9),C1:C7))
The following formula will give the answer (shown in A9 above):
=INDEX(A1:A7,MATCH(TRUE,(MMULT(--($B1:G7=$B9:G9),--(ROW(INDIRECT("1:"&COLUMNS($B9:G9)))>0))=COLUMNS($B9:G9)),0))
UPDATE WITH ALTERNATIVE METHOD
Using a helper column instead, again referencing the image below (the data are in A1:G7):
I1 (fill down to I7)-->
=SUM(--(MMULT(SIGN(B1:G1-$B$1:$G$7)*2^(COLUMN(G1)-COLUMN(A1:F1)),--(ROW(INDIRECT("1:"&COLUMNS(B1:G1)))>0))>0))
The following formula will give the answer (shown in J1 above):
=INDEX(A1:A7,MATCH(MAX(I1:I7),I1:I7,))
As a bonus, notice that the helper column corresponds to the order that you would get from sorting the data by each column left-to-right. In other words, you could use the helper column to perform a formula-based multi-column sort on strictly numeric data. For the last image, entering the following array formula into a range with the same dimensions as A1:G7 gives a descending sort on columns B through G:
=IF(A1:A7=A1:A7,INDEX(A1:G7,MATCH(ROW(A7)-ROW(A1:A7),I1:I7,0),))
I have a table of data that include a name column and two numeric columns. Example:
A B C
Fred 4 2
Sam 3 6
George 1 7
I'm wanting to retrieve the name in column A for the largest sum of columns B and C. In the example above, I would want "Sam" because 3+6 is greater than any of the other sums.
I know I could create a hidden column (D) that's filed with
=SUM(B2,C2)
and do something like this:
=INDEX(A:A,MATCH(MAX(D:D),D:D,0))
but I'd rather avoid the hidden column, if possible. Is there a way to perform an index-match based on the sum of two cells?
Use the array formula:
=INDEX(A:A,MATCH(MAX((B:B)+(C:C)),(B:B)+(C:C),0))
Array formulas must be entered with Ctrl + Shift + Enter rather than just the Enter key.
(Note the appearance of braces in the formula bar)
I have an excel sheet in CSV that has 8 columns A-H and thousands of rows with values 0 or 1 depending on truth value.
I'm looking for the Excel function in which I can select rows where column A and B are true so that I can check another columns probability given A&B. IE P((A&B)|D) (where | means given).
I'm really new to excel and having difficulties finding how to only select rows that meet this criteria.
The following formula entered in I1 will return a 1 if both A1 and B1 are true.
=IF(AND($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 have a spreadsheet that has 4 columns sheet 1, and 5 columns sheet2 and I need to do a vlookup on Sheet1!a2&c2 and match the row in sheet2!a2&c2 and return sheet2!c5.
I think Index and Match would do it but all the examples have been matching a single value to an array which isn't what I need for eg.
Can't do attachments yet :( text it is sorry for the format
Sheet1
R1 A B C D
R2 2 D 3 Result will match sheet1!a2&c2 to sheet 2!A3&C3 and return Sheet2!e3 ie 34
Sheet2
R1 A B C D E
R2 2 F 5 GR 72
R3 2 X 3 FR 34
Any links or help?
Update
Sorry I wasn't clear I want to match the cobination of A2 and C2 in sheet 1,
ie in the example =sheet1!A2&sheet1!c2=23
to the values in sheet2!a2 plus sheet2!c2,
ie in this example =Sheet2!a3&Sheet2!c3=23,
and then return the value in Sheet2!E? , ie Sheet2!E3=34 here
I've done this before by creating a cheat column in sheet 2 = a2&c2 in say d2 and filling down then using, assuming 3 rows, however I can't create the cheat column in sheet2
=vlookup(a2&c2,sheet2!d2:e3, 2, false)
The rows sheet2! look like, sorry about the formatting
Picture attached, which I suddenly got to do , where I need to match the yellow columns in the lookup then return the brown column to sheet1!E2 but I can't add the cheat column Sheet2!d2:3 to the sheet cause the user is difficult :)
Thanks again. Any good tutorial on Index?
Try using LOOKUP like this
=LOOKUP(2,1/(A2=Sheet2!A$2:A$10)/(C2=Sheet2!C$2:C$10),Sheet2!E$2:E$10)
The two "tests", i.e.
(A2=Sheet2!A$2:A$10)
and
(C2=Sheet2!C$2:C$10)
return "arrays" of TRUE/FALSE values but when you divide 1 by one of those and then the other TRUE is converted to 1 and FALSE to 0 so you get a resulting array of either 1s (where both conditions are TRUE) or errors [#DIV/0!] where one or both are FALSE.
When you lookup 2 in that array it will never be found so it matches with the last 1, i.e. the match is with the last row where both conditions are satisfied...and the corresponding value from Sheet2!E$2:E$10 is returned. Another way is like this:
=INDEX(Sheet2!E$2:E$10,MATCH(1,(A2=Sheet2!A$2:A$10)*(C2=Sheet2!C$2:C$10),0))
which requires "array entry" with CTRL+SHIFT+ENTER
