I have excel sheet contain 600 thousand row, I want to select one column.
for example please see the attachment picture
Here in the column there are multiple values, I want to count it and the result must be for example
number of value 1 it's = 55
number of the value 8 it's = 23
seems this to do it's easy but I have 600 thousand with multiple values.
It all depends on how many times you have to change the column and what you have to do with the informations you get.
Without this info the best solution is the following:
select the column you have to analyze;
push Insert;
hit Pivot table
select Pivot Table.
Now you have only one field that you can put inside ROWS and inside VALUES (select COUNT).
This will give you an unique list of the elements and the amount of each one.

I am having two tables, one table (table 1) below is main data, separated into many columns and blocks per 10 rows in one, as you can see A2:A11, A12:A21 and so on (many rows and columns) ... In Column A are unique numbers, but one number per block as a unique, and all other information in other columns can differ, sometimes will be more data sometimes not. The data is always same structured.
What I am looking is to have report / printable sheet where I will have all my columns on one sheet, but in a Column A2 for instance drop down list that will use all unique numbers from main data table and populate all matches on report page, same as it is on picture below. There are many columns that should work automatically when I choose something from "Number" drop down. The trick here is, there must be 10 rows per block also, I have organized it as it should be, but I can't figure out how to populate using functions. So, you can imagine clicking one drop down and getting those lists updated without scrolling endlessly through columns and rows on main data table...
Where I have a problem is that I am getting matches only for first rows but not whole rows (or all rows where matches are) ...
using this function:
=INDEX(Table1[Datum];SMALL(IF(Table1[Nummer]=Printable!$A$2;ROW(Table1[Nummer])-ROW(INDEX(Table1[Nummer];1;1))+1);1))
If someone can help me out, I would be happy!
Try below formula. After putting formula to cell drag down and across as needed. I have tested this formula in Excel2013 and with range (not as table). So, you have to adjust formula for table. I suggest you to first test the formula in single sheet like my screenshot and if it is successful then go for table in Report sheet.
=INDEX(INDEX(B:B,MATCH($G$2,$A:$A,0)):INDEX(B:B,MATCH($G$2,$A:$A,0)+9),ROW(1:1))
I have a list of items in one column and a total number in another column. I need to combine every instance an item appears in column A and the amounts in column B. I also need it to sort by highest number first on its own if possible. Here is an example of what I mean.
Column A & B is my list, Column D & E is what I want the results to look like:
Can anyone help out? I've racked my brains for days and cant seem to get it to work. Thanks.
This is what pivot tables do...
Create a pivot table Image below.
place cursor in D2
Menu - Insert
Tables - Pivot table
Select range of data
fill out fields on right as in image. (I had A on line 2 = 3 so my total said 14 and didn't refresh before I took the screen capture)
right click on a value in the sum of total column and click sort from popup and select largest to smallest.
I have a bunch of rows in a table. Each row reflects an event in a patient. However, one patient can have experienced multiple events, so it's possible for there to be multiple rows with the same patient number. Now I'd like to count the amount of male patients in my database, without counting the ones that had multiple events multiple times. Each patient is identified by a unique patient ID that could be used for this.
This shouldn't be all that complicated if not for the fact that I'm using a table that also has several filters, so I need to use SUBTOTAL for any counting functions.
I literally have no idea where to start, so I can't really provide any code...
Any function that could point me in the right direction would be greatly appreciated.
Thanks for the help.

Use a Pivot Table to filter and count all your patients database. Select your data and select Insert -> Tables -> Pivot Tables. Put your filters at the Filter section of the table and the Patient ID in the Rows section. Then, you can use COUNT to get the number of patients.
For more information about Pivot Tables, you can check this: https://support.office.com/en-us/article/Create-a-PivotTable-to-analyze-worksheet-data-a9a84538-bfe9-40a9-a8e9-f99134456576
To get the number of unique IDs in the same column, if the IDs are numeric, you can use SUM with FREQUENCY:
=SUM(IF(FREQUENCY($A$1:$A$1000,$A$1:$A$1000)>0,1))
If they're text and numbers mixed, you can get unique IDs with this one:
=SUM(IF(FREQUENCY(MATCH($A$1:$A$1000,$A$1:$A$1000,0),MATCH($A$1:$A$1000,$A$1:$A$1000,0))>0,1))
(From here)
Here you go
You've not mentioned whether an event is optional.
You might want to add extra column H with formula like h2=if(c2="",0,1) with 1/0 and multiply it as well in G.
Basically if column G contains a 1 you include it
Here's what the results of the formula look like:
Revision
Table is sorted by Patient id..
on change of patient id column H contains a 1, it'll be 0 otherwise.
So H2 is hard coded to 1, H3,H4,H6 will evaluate to 1.
So now G2=H2*E2 etc. You can filter by column H.
The beauty of mapping things into binary zeros and ones is you can do multiplication to achieve a logical AND result, whilst at the same time breaking a complex task into a series of steps. You can then apply a filter to the data to get the rows where column G are not zero, and see the totals count. Normally I'd insert a column between header and data on row 2 and then have G2=SUM(G3:G9)
Sum column H for number of patients.
I have a spreadsheet with ~8000 records, there are ~400 unique identifiers (i.e. element 101, 102, 103....500) that I need to calculated means for. Is there a simple way to calculate means on large datasets like this?? Or will I have to do =average('select column block') for each subgroup/unique identifier?
Many Thanks
Use the following formula
=AVERAGEIF($A$1:$A$8000,"=IDNUMBER",$B$1:$B$8000)
Where
Column A is your column of ID numbers
Column B is your list that you need the mean from.
If your ID numbers are sequential, you can set up something like:
=AVERAGEIF($A$1:$A$8000,"="&100+row(A1),$B$1:B8000)
And copy that down from say C1 to C500
Alternatively you could make a list of the unique identifiers with another formula and place that unique list in C1 to C500 and then in column D use the following:
=AVERAGEIF($A$1:$A$8000,C1,$B$1:$B$8000)
If you have a header row you will need to adjust your ranges accordingly
The formula to generate a unique list of IDs is:
=INDEX($A$2:$A$8001,MATCH(0,INDEX(COUNTIF($C$1:C1,$A$2:$A$8001),0,0),0))
Use that in column C but in row 2 and copy down. So if your data starts in row 1 you will want to bump it down 1 row.
Create a pivot table with the unique identifiers in the rows and calculate the average of the values.
For data that is clustered up nicely and immediately ready to be handed off for a visual review of the averages try a creating a Subtotal:
Select your data
Go to Data > subtotal (far right on the tab)
On the menu popup in the At each change in field, select the column header name that corresponds to your unique identifier.
Select Average for Use function. Select the checkbox of the column for which you want to find the group's mean.
Select other formatting features if desired (defaults typically work best)
Click okay.
Take a sip of coffee and let the magic happen.
I have a data set in excel with four columns;
Username, Computer, Department information
I have used a filter to select all unique usernames in the data set, then have used counif() to count how many times the username occurs in the data set - This works fine.
Now I want to search the original data set for every time a specific username appears and when it does, I want to select the 'information' cell to that relevant row. So the output will be an array rather than one value,
example,
Username|Information
A 1
A 2
B 3
A 4
D 5
So if I use my function to search for all values from 'information' with username A, I want this to output,
Information
1
2
4
Thanks.
Here's one method that doesn't involve VBA. It may not be practical for your needs though.
Make a pivot table based on your data
Add Username to the Filter
Add Information as a Row
Change the Filter from (All) to your desired username.
If you need to rerun the underlying dataset, just right click to refresh the pivot table.
