I have got an excel question that I can not answer. Here is my table:
ID Key Count Unique Available Text Results
1 0 Text-1 Dupe-Y
2 1 Y Text-1 Y
3 0 Text-1 Dupe-Y
4 0 Text-1 Dupe-Y
5 1 N Text-2 N
6 1 Y Text-3 Y
7 0 Text-2 Dupe-N
8 0 Duplicate Text-2 Dupe-N
9 0 Duplicate Text-2 Dupe-N
10 0 Y Text-2 Dupe-N
Id Key is just unique key.
Count unique picks up the first time each value in column Text appears. Available can have Y, N, Duplicate and Text is the main column I need to analyze my table. The Results are for the first time each value in Text appears (Count unique = 1), if there is a value in Available then that is the value I need, if Count Unique is 0 then is either Dupe-Y or Dupe-N depending on the value in Available.
I tried with a formula like this one but got stuck after initial progress. =IF(B2=0,"",IFERROR(IF(COUNTIF(D:D,D2)>1,IF(COUNTIF($D:$D,D2)=1,"",C2),1),1))
Note that the column Results is the one I need to populate with a formula that is not affected by sorting or lack of it.
I guess you got all those values and you just need a formula for column Results.
My formul will work only if the data is sorted like in your example. If sorting changes, formula will fail:
My formula is:
=IF(B2=1;D2;"Dupe-"&RIGHT(G1;1))

I have a list of 4 values in Sheet1 and 4 values in Sheet2.
In Sheet3 I will combine a random selection of these numbers and return the value in a column. (edit: no random selection from Excel, its a part picked from a bucket)
(A fifth column in Sheet3 will be used to do calculations with ValueS1 and ValueS2)
Sheet1
NumberS1
ValueS1

What kind of function can give the desired return?
I have looked into examples using "Indirect" but cannot see how they will solve my problem.
for the randomization: =ROUNDUP(RAND()*4,0)
rand() gives you a number between 0 and 1, so rand()*4 gives you a number between 0 and 4.
roundup(x,y) round up the number x with y digits you want to round the number up to (in our case 0).
for import the right number from sheet 1 or 2: =VLOOKUP(A1,Sheet1!A1:B2,2,0)
A1 - The value you look for in sheet 1 or 2.
Sheet1!A1:B4 - The array he look for your value on the firs column, always on the first column.
2 - The column you want to import the value from. (because we write an array of tow columns. we can write here only 1 or 2)
0 - it's an Optionally index (0 or 1). o is if you want an exact match of the return value.
Regular Lookup could do:
=LOOKUP(A2:A5,Sheet1!A2:A5,Sheet1!B2:B5) in Sheet3!C2
And
=LOOKUP(B2:B5,Sheet2!A2:A5,Sheet2!B2:B5) in Sheet3!D2
Note that LOOKUP will give the result to the closest match smaller than the search value.
Or VLOOKUP:
=VLOOKUP(A2:A5,Sheet1!A2:B5,2,0) / =VLOOKUP(B2:B5,Sheet2!A2:B5,2,0)
VLOOKUP will error if the value is not found (the way used above). It uses arguments like this:
=VLOOKUP(What you want to look up, where you want to look for it, the column number in the range containing the value to return, return an Approximate or Exact match – indicated as 1/TRUE, or 0/FALSE)
Office 365 has XLOOKUP which combines the logic of the two above and some more:
=XLOOKUP(A2:A5,Sheet1!A2:A5,Sheet1!B2:B5,"value not found",0)
XLOOKUP uses the following arguments:
=XLOOKUP(lookup_value, lookup_array, return_array, [if_not_found], [match_mode], [search_mode])
I'm looking for a formula calculating : distinct Count + multiple criteria
Countifs() does it but do not includes distinct count...
Here is an example.
I have a table on which I want to count the number of distinct items (column item) satisfying multiple conditions one column A and B : A>2 and B<5.
Image description here
Line Item ColA ColB
1 QQQ 3 4
2 QQQ 3 3
3 QQQ 5 4
4 TTT 4 4
5 TTT 2 3
6 TTT 0 1
7 XXX 1 2
8 XXX 5 3
9 zzz 1 9
Countifs works this way : COUNTIFS([ColumnA], criteria A, [ColumnB], criteria B)
COUNTIFS([ColumnA], > 2 , [ColumnB], < 5)
Returns : lines 1,2,4,5,8 => Count = 5
How can I add a distinct count function based on the Item Column ? :
lines 1,2 are on a unique item QQQ
lines 4,5 are on a unique item TTT
Line 8 is on a unique item XXX
Returns Count = 3
How can I count 3 ?!
Thanks

Newer versions of Excel allow for this problem to be solved in a (relatively) more simple way. It certainly is easier to follow and understand, conceptually.
First, filter the table based on multiple criteria (join multiple with the *):
=FILTER(Table,(Table[Column A]>2)*(Table[Column B]<5))
Then, grab the "Item" column with INDEX:
=INDEX(FILTER(Table,(Table[Column A]>2)*(Table[Column B]<5)),,2)
Next, filter for unique entries:
=UNIQUE(INDEX(FILTER(Table,(Table[Column A]>2)*(Table[Column B]<5)),,2))
Finally, perform a count:
=COUNTA(UNIQUE(INDEX(FILTER(Table,(Table[Column A]>2)*(Table[Column B]<5)),,2)))
Ugly formula, but it works.
=SUM(((FREQUENCY(IF(C2:C10>2,1,0)*IF(D2:D10<5,1,0)*(COUNTIF(B2:B10,">"&B2:B10)+1),ROW(B2:B10)-ROW(B2)))*(ROW(B2:B11)-ROW(B2))>0)*1)
I'll start with the criteria IFS:
IF(C2:C10>2,1,0)*IF(D2:D10<5,1,0)
Gives an array of 1s and 0s for the rows that satisfy both criteria. ARRAY = {1;1;1;1;0;0;0;1;0} for your example.
Where B2:B10 is the Item column, the countif formula:
COUNTIF(B2:B10,">"&B2:B10)
returns {6;6;6;3;3;3;1;1;0} where the number equals the number of item values in B2:B10 alphabetically less than the tested item value.
QQQ goes to 6 [3"TTT", 2"XXX", 1"zzz"]
TTT goes to 3 [2"XXX", 1"zzz"]
XXX goes to 1 [1"zzz"]
zzz goes to 0 [0 less than "zzz"]
Need to add 1 to this array to make sure there are no 0 values:
{7;7;7;4;4;4;2;2;1}.
So when multiplying the criteria, and the countif statement:
(IF(C2:C10>2,1,0)*IF(D2:D10<5,1,0)*(COUNTIF(B2:B10,">"&B2:B10)+1)
You get ARRAY = {7;7;7;4;0;0;0;2;0}.
FREQUENCY(ARRAY,ROW(B2:B10)-ROW(B2))
ROW(B2:B10)-ROW(B2) sets the frequency bins to {0;1;2;3;4;5;6;7;8}. So the output of the frequency formula is {4;0;1;0;1;0;0;3;0;0} where the last 0 is for all values greater than 8.
((ROW(B2:B11)-ROW(B2)>0)*1) equals {0;1;1;1;1;1;1;1;1;1}. Multiplying ARRAY by this removes the 0 count at the start: ARRAY = {0;0;1;0;1;0;0;3;0;0}. [NOTE: B11 is lowest item column cell+1 because of the added array value from the frequency formula for values over 8]
(ARRAY)>0)*1 = {0;0;1;0;1;0;0;1;0;0}
SUM this = 3.
ctrl + shift + enter, because it's an array formula.
cmd + shift + enter for mac.
You could try this:
=SUMPRODUCT(1/COUNTIF(B2:B10,B2:B10))
Credit where credit due, however ... I found it over here:
https://exceljet.net/formula/count-unique-values-in-a-range-with-countif
I'm looking for a way to find the first specific value above a certain cell.
Using the example below, in the result column every time I hit a A in COL2, I need to substract the value in COL1 to the first A value above.
The trouble seems finding a way to keep the range dynamic...
I thought of =IF(B5="A";A5-INDIRECT("A"&MATCH("A";B:B;0));"")
But of course that only works for the first one as Match will always pick up the first one.
Any ideas? Thanks!
Example :
COL1 COL2 Result
1 A
2 0
3 0
4 A 4 - 1 = 3
5 0
6 A 6 - 4 = 2
7 0
8 0
9 0
10 A 10 - 6 = 4
Try this:
=IF(AND(ROW(B2)<>2,B2="A"),A2-INDEX($A$1:$A1,AGGREGATE(14,6,ROW($1:1)/($B$1:$B1="A"),1)),"")
The AGGREGATE() Function was introduced in 2010.
In D2 enter =IF(B2="A",A2-INDIRECT("A"&MATCH("A"&(E2-1),F:F,0)),"")
In E2 enter =IF(B2="a",COUNTIFS($B$2:B2,"a"),"")
In F2 enter =B2&E2
Copy formulas from D, E and F down all your rows
Column D is the result you're looking for
I have numeric data under fifty samples that are mostly similar. I want to count identical columns and give statistics on the same. There are too many rows to select them (37,888). Data looks like:
Sample 1 Sample 2 Sample 3 ........ Sample 50
4 4 0
4 4 0
4 4 ...
0 0
0 0
0 0
0 0
... ...
upto thousands of rows for each sample.
There is a column for date/time as well, would be nice if I could include that in the grouping.
In this snippet, there are many rows. Sample 1 and 2 are identical hence should be grouped together. Sample three would form another group and so on.
While I'm not sure what "There are too many rows to select them" means in this context (there is no limit on the number of rows or items that can be selected and included in a formula), this looks like a job for array formulas.
If you want to determine (for instance) whether columns C and D are equal, from rows 1 through 37888, you can use this formula:
=AND(C1:C37888=D1:D37888)
To make Excel treat this as an array formula, you need to press CTRL-SHIFT-ENTER (Windows) or CMD-ENTER (Mac) after typing the formula. The "AND" function will return TRUE if and only if all corresponding entries are equal: C1=D1, C2=D2, C3=D3, ..., C37888=D37888. It returns FALSE if any corresponding entries disagree.
Exactly what you do next will depend on the nature of the statistics that you want to compute for each group, but this formula will at least help you figure out which columns belong in the same group together.
I have an Summary sheet set up data set up as follows-
Cat A Cat B Cat C Cat D
Name 1 0 0 0 0
Name 2 2 3 2 2
Name 3 2 2 2 2
Name 4 3 2 2 3
Name 5 2 3 2 3
I also then have separate tabs for each of Name1 through to Name 5.
The summary sheet contains the maximum values for each category from each tab. So the Cell at Cat A Name 1 should show the maximum value on Sheet(Name1) in the Cat A column.
So far so good. However each tab may not contain the same categories, so therefore I would like teh summary sheet to check the maximum value in each column by doing a search on the Cat name.
So far I have this-
=MATCH(Overview!S$1,Name1!$C$1:$V$1,0)
Which returns the column number with the right Category, in this case 13. So I can find the right column. What I am struggling with is to now find the maximum value in the column.
Can anyone help?
Thanks
IAssuming your search range goes to row 1000:
=MAX(INDEX(Name1!$C$2:$V$1000,0,MATCH(Overview!S$1,Name1!$C$1:$V$1,0)))
The 0 Row argument in Index means to select the entire column.
The Offset function is your key here.
After you've got the value from the match, you can pass it to the offset to get the correct column.
So, for example, you probably want something like:
=Max(Name1!$C1:$C2000)
But you don't know whether you should use the C column or the D column or whatever, in this case, it was 13, so is that the P column? (c=3, the match was 13 so 3+13 = 16 = P?), so I think you want something like this:
=Max(Offset(Name1!$C$1:$C$2000, 0, [result of your match expression] - 1))
Here's an example of what I think you want in GoogleDocs:
